Phillips Lytle LLP is a premier regional firm with a fast-paced energy practice providing cutting-edge expertise to various utilities, developers, owners, pipeline companies, retail energy suppliers, and financial partners involved in renewable and other energy projects. With six offices across New York State and offices in Washington, DC, Cleveland, Ohio and Ontario, Canada, Phillips Lytle’s Energy Practice spans New York State Public Service Commission (PSC) and utility regulatory, siting, zoning and environmental, solar, wind, brownfield and landfill renewable energy projects, energy storage, incentives, bonds and public finance, power purchase agreements, solar leases, microgrids, hydro, biomass, retail energy industry, enforcement and investigations, and litigation and dispute resolution. With the increased demand for energy expertise beyond the legal realm, the firm established Phillips Lytle Energy Consulting Services to help navigate the complex policies in the energy industry and provide guidance for project development, transactional support, energy policy, regulatory counselling and procurement consulting.

The US power industry is comprised of four main segments:

  • generation;
  • transmission;
  • distribution; and
  • supply.

No single entity sets policy for each segment. The US legal system operates according to the concept of shared sovereignty: governmental power is divided between state institutions and the federal government. Wholesale power markets and interstate transmission systems are generally governed by federal regulation, while retail power markets and distribution systems are generally governed by state regulation. The contours of state and federal jurisdiction are increasingly being blurred with the advent of new technologies and policies in the evolving 21st-century power industry.

State Utility Commissions

Individual state utility commissions are the collective architects of the US power sector. They are each uniquely structured, but generally comprised of between three and seven members, who may be elected or appointed, with authority granted by either the state legislature or state constitution to balance policies and preferences related to reliability, affordability, environmental impacts, consumer protection, utility profitability and security. Federal laws and policies governing the power sector are typically implemented by the states, which are layered with independently generated state laws and policies, all of which are distilled and implemented by state utility commissions.

There are two broad classes of utilities in the USA – private investor-owned utilities (IOUs) and public utilities. Within each class are three general types. Private IOUs include vertically integrated, restructured and retail. Public utilities include municipal, co-operative and miscellaneous. Each class and type has a unique historical structure and legal framework.

Vertically Integrated IOUs

Vertically integrated IOUs are for-profit shareholder-owned entities that take on the functions of generating, transmitting and distributing electricity to the customer and operate within a defined service territory as a regulated monopoly. In restructured states, the generation function has been opened up to competition such that retail customers can choose to receive energy supply from an alternative supplier, which is transmitted and distributed by the IOU. Restructured IOUs, therefore, operate primarily as transmission and distribution companies.

In restructured states, a significant share of power is provided by merchant generators as many IOUs were required or incentivised to sell off most of their generation portfolio to make room for competition. The final category of privately owned utilities is competitive retailers that serve as commodity suppliers and brokers.

Public Utilities

Public utilities are comprised of municipal utilities, co-operatives and uniquely structured miscellaneous entities. Municipal utilities are primarily distribution utilities that purchase wholesale power to serve their retail customers. Co-operatives are consumer-owned, not-for-profit entities that can be either distribution-focused businesses that serve member customers, or generation and transmission entities that serve distribution co-operatives. The final category of public utilities includes those that are the product of state and/or federal statute to provide utility services to a particular district, or to market electricity from certain hydroelectric dams.


Integrated IOUs and municipal utilities were the first to emerge in the late 1800s as commercial electrical generation and distribution became widespread. As early utility competition resulted in the construction of parallel redundant power lines and infrastructure, prices plummeted and many utilities were led to bankruptcy. Those that remained were granted a defined geographical service territory in which they could operate as a monopoly in exchange for government regulation under what is known as the "regulatory compact".

In the 1930s, President Franklin D. Roosevelt enacted a series of economic measures to counteract the effects of the Great Depression (the "New Deal"), which included, among other things, passage of the Federal Power Act of 1935 (FPA), the Rural Electrification Act of 1936 (REA), and the creation of certain federally authorised public utilities. The FPA established jurisdictional boundaries between the federal government, which regulates wholesale sales and interstate transmission, and the states, which exercise authority through state utility commissions that oversee retail sales and distribution infrastructure.

To promote electrification of underserved rural areas, the REA provided funding to a new class of utility – publicly owned co-operatives. Further electrification efforts were driven by the creation of various congressionally created federal corporations and authorities such as the Tennessee Valley Authority and the Bonneville Power Administration, among others, which generally fall into a broad class of "miscellaneous" public utilities as each is uniquely structured and governed.


The Public Utilities Regulatory Power Act of 1978 (PURPA), created as a response to the 1970s energy crisis, encouraged conservation and created a market for non-utility power producers by requiring utilities, in certain circumstances, to purchase power generated by qualifying facilities. PURPA was implemented by each state, resulting in a range of regulatory regimes across the country. PURPA paved the way for a series of Federal Energy Regulatory Commission (FERC) orders which promoted open access to transmission facilities (Orders 888 and 889) and independent system operators (ISOs) (Order 2000). Beginning in the 1990s, a number of states further deregulated the vertically-integrated utility sector such that now 16 states and the District of Columbia have active retail choice programmes.

The Energy Policy Act of 2005 (EPAct) represents one of the most significant pieces of federal legislation in the energy sector since the New Deal. It grants FERC enhanced authority to prevent market manipulation and abuse, assess extraordinary civil penalties, approve siting of major transmission projects and implement reliability standards across the county’s electric grid.

The US electric industry is comprised of over 3,000 electricity providers, which include over 2,000 publicly owned utilities, over 800 co-operatives, nearly 200 IOUs and over 200 power marketers. The largest vertically integrated public utility holding companies include Duke, Southern Company, NextEra, Entergy, Dominion and Xcel. The largest restructured public utility holding companies include PG&E, Exelon, Edison International, Consolidated Edison, First Energy, National Grid and Northeast Utilities. The largest retailers include AEP, NRG, EFH, Exelon and ConEd. The largest public power systems, based on net generation, are the New York Power Authority, the Salt River Project and CPS Energy.

While US utilities or utility holding companies may have foreign ownership, and the USA maintains – in principle – an "open investment" policy, that policy has been tempered by concerns about national security. The 1988 Exon-Florio Amendment to the Defense Protection Act of 1950 authorises the President of the United States, through the inter-agency Committee on Foreign Investment (CFIUS), to review foreign investments that may impact national security, and block investment or impose certain conditions upon credible evidence of a security threat. Such executive decisions are not reviewable by state or federal agencies or courts.

The Foreign Investment and National Security Act of 2007 (FINSA) enhances the Exon-Florio Amendment by broadly defining the type of infrastructure transactions covered and adding more stringent rules pertaining to review and investigation of foreign investments. In 2018, Congress enacted the Foreign Investment Risk Review Modernization Act (FIRRMA), which expands the scope of transactions covered under CFIUS’s jurisdiction, including certain real estate transactions and investments involving personal data and critical infrastructure.

On 1 May 2020, President Tump issued an Executive Order prohibiting the acquisition, importation, transfer or installation of any “bulk power system electric equipment” that is designed, developed, manufactured or supplied by entities owned or controlled by a “foreign adversary,” where such transaction would pose undue risks to critical infrastructure or security. The ambiguity of terms, including “bulk power system electric equipment” and “foreign adversary,” has created some uncertainty which will need to be resolved in subsequent guidance or implementing regulations.

The sale of generation, transmission and distribution system assets, as well as the merger of industry entities generally requires federal and state approval. At the federal level, the sale, lease or disposition of facilities valued at over USD10 million under FERC’s jurisdiction that are used for transmission or sale of electric energy in interstate commerce and generation assets making wholesale sales require FERC approval under Section 203 of the FPA. FERC approval is also required to effectuate mergers, acquisitions, or change in control of jurisdictional facilities.

In examining such transactions, FERC reviews the effect on competition, rates, cross-subsidisation and whether the transaction is consistent with the public interest. To streamline the processing of certain transactions, FERC issues "blanket authorisations" for certain dispositions of utility securities and contracts that make it easier for entities to engage in sales and purchases for investment purposes – eg, corporate reorganisations that do not present cross-subsidisation issues, or acquisitions by holding companies of voting securities so long as the acquiring company owns less than 10% of the outstanding voting securities.

Additional requirements may apply to transactions involving nuclear generation facilities, which require NRC approval to effectuate an asset transfer. At the state level, state utility commissions are often required to approve acquisition or divestiture of power assets in accordance with state law and regulation.

The USA does not have a central planning authority that oversees and administers the electricity supply and development of transmission facilities. The USA is broadly divided into three electric grids – the Eastern Interconnection, Western Interconnection and the Electric Reliability Council of Texas. Across those three grids are seven competitive wholesale power markets operated by the following FERC-regulated organisations which provide non-discriminatory access to the transmission network:

  • the New York ISO;
  • the California ISO;
  • the Electric Reliability Council of Texas;
  • New England ISO;
  • PJM Interconnection;
  • Southwest Power Pool; and
  • the Midcontinent ISO.

These nine RTOs/ISOs serve two-thirds of the USA. Certain states in the South, Mountain West and Northwest did not join an RTO/ISO and continue to operate independently of the RTO/ISO wholesale markets. RTOs/ISOs are responsible for maintaining operation of the grid, ensure demand meets supply through capacity auctions and market mechanisms, and are governed by FERC tariffs, rules and regulations.

Neither FERC, nor RTOs/ISOs, are responsible for making resource mix decisions, as such authority lies solely with each state. Some states require utilities to perform integrated resource planning and demonstrate how utility infrastructure and investment will meet the needs of customers. Other states impose legislation and/or regulation to mandate or incentivise a certain resource adequacy mix. State-level policy regarding electric supply varies depending on geography, politics and statutory authority, as well as regulatory goals.

The EPAct empowered FERC with authority to ensure the reliability of the bulk power system. FERC certified the North American Electric Reliability Corporation (NERC) as the Electric Reliability Organization charged with developing and enforcing reliability standards for power system operation to ensure reliability through compliance audits, investigations and training.

Material changes in law or regulation occur frequently at the state level, particularly with respect to the emerging role of alternative energy resources. Notably, in the last year, six states – plus Puerto Rico and Washington, DC – have adopted legislation targeting 100% clean energy, each with distinct timelines, definitions and mandates.

Federal Level

At the federal level, several recent orders and regulations have been promulgated that impact the power industry. In December 2019, FERC issued an order requiring certain new resources that receive state-level clean energy subsidies to be subject to a Minimum Offer Price Rule (MOPR) that would effectively raise the price floor for such resources selling into the PJM Interconnection’s wholesale market (“MOPR Order”). PJM Interconnection, L.L.C., 171 FERC ¶ 61,034 (April 16, 2020) (Docket Nos EL16-49-001, EL 18-178-001, ER18-1343-002 (consolidated)); 171 FERC ¶ 61,035 (April 16, 2020) (Docket Nos EL16-49-002 and EL18-178-002 (consolidated)).

FERC claims the MOPR Order is necessary to prevent potentially distorted price effects allegedly caused by state clean energy policies. Some states in PJM are concerned that the MOPR Order will undermine state-level objectives to develop and expand renewable energy markets, and have launched investigations to evaluate alternatives to PJM Interconnection’s capacity markets to otherwise support clean energy objectives.

Legal Challenges

Legal challenges to the methodology of the United States Environmental Protection Agency’s (EPA) regulation of greenhouse gas emissions for existing power plants under the Clean Air Act remains ongoing. In June 2019, the EPA repealed the Obama administration’s Clean Power Plan (CPP) and replaced it with the Affordable Clean Energy rule (ACE). Unlike the CPP, which would have, among other things, established state-specific carbon reduction targets and allowed states to develop their own unique plans to achieve those targets, the ACE rule sets guidelines for states to establish unit-specific performance standards at certain coal-fired power plants.

A coalition of states, lawmakers and other stakeholders has challenged the repeal of the CPP, the ACE rule replacement and the revisions to the EPA’s regulation of CO2 emissions. While the EPA is obligated to regulate greenhouse gases, the method and manner of such regulation will be tested in ongoing litigation regarding the CPP and the ACE rule. In the meantime, state and local regulations of greenhouse gases are not superseded by the ACE rule and remain an effective tool used by states to achieve clean energy and climate objectives.

"Green New Deal"

As 2020 is an election year, Democratic members of Congress have called for a “Green New Deal” that would aim to promote economic development and job growth through nationwide efforts to reduce greenhouse gas emissions. It would also deploy clean energy assets across all sectors of the economy, including power, transportation, buildings, electric transmission networks, sustainable agriculture, and research and development activities. It remains to be seen how broad decarbonisation policies will be translated into specific, practical programs.

In the meantime, a growing number of state and local governments are pushing clean energy and climate policies on their own initiative, either to maintain operation of low-carbon generation or to deploy additional clean energy resources. Many of those states and local governments are targeting 100% clean power in the coming decades, each with state- or municipal-specific laws, rules and regulations.

Integrating Energy Storage

FERC has begun to integrate energy storage into the wholesale market by issuing Order 841, which directs RTOs/ISOs to establish rules that compensate flexible resources – such as energy storage located on the transmission system, distribution network or behind-the-meter – that can provide value to the capacity, energy and ancillary services markets. FERC has issued several orders on Order 841 compliance filings, including orders which largely accept PJM Interconnection’s and Southwest Power Pool’s tariff revisions and proposed market rules designed to incorporate electric storage resources. In July 2020, the Court of Appeals for the District of Columbia issued a landmark decision upholding FERC’s Order 841 against legal challenges by affirming that energy storage resources must have the option to access wholesale markets and that states may not interfere with FERC’s authority by banning electric storage systems from participating in federally regulated wholesale markets. National Association of Regulatory Utility Commissioners v Federal Energy Regulatory Commission, No 19-1142 (D.C. Circa 10 July 2020).

Carbon Pricing Programme

The New York Independent System Operator (NYISO) has proposed a first-of-its-kind carbon pricing programmme in its competitive wholesale energy market to complement New York State’s Climate Leadership and Community Protection Act, which, among other things, requires 70% of the State’s electricity to be procured from renewable resources by 2030. The NYISO’s carbon pricing program is the first attempt by an RTO/ISO to explicitly integrate the full social cost of carbon into a regional energy market. The carbon pricing proposal would need to be submitted to FERC for approval, at which point it will likely raise questions and face legal challenges regarding the interplay of state, regional and federal jurisdiction over energy markets.

Reforms to Public Utility Regulatory Policies Act

In July 2020, FERC issued Order 872 which revises regulations that govern qualifying small power producers under the Public Utility Regulatory Policies Act of 1978 (PURPA). The rule imposes significant reforms, including granting states flexibility establish avoided cost rates for energy sales; establishing a framework for states to set avoided cost rates based on competitive solicitations; amending the “one mile rule” for determining whether generation facilities are considered to be at the same site for purposes of complying with qualifying size thresholds; and reducing the size thresholds for existing rebuttable presumptions regarding non-discriminatory access to markets.

Investors and market participants should consider the powerful role played by state utility commissions in the architecture and development of the US power industry – particularly as technology applications trend towards smaller-scale distributed energy resources and locational value-based pricing mechanisms.

The COVID-19 pandemic raises concerns for alternative energy project developers, while also providing potential opportunities that could emerge as the federal government and states seek to spur economic development, eliminate inefficiencies and create employment opportunities.


From the developer perspective, construction timelines may be impacted by global disruptions to critical supply chains, state or municipal stay-at-home orders that prohibit construction activities, or social distancing measures that slow down permitting and inspection processes. Alternative energy developers that seek the ITC or PTC may need to evaluate force majeure claims to the extent COVID-19-related disruptions cause delays that could risk receipt of otherwise expected credits or impact contractual obligations. For example, a developer seeking to qualify for the ITC or PTC must have commenced construction by the end of 2019.

In May 2020, the US Department of the Treasury and IRS issued Notice 2020-41, which adds an additional year – from four years to five years – for renewable project developers to complete projects started in 2016 and 2017 that seek the full value of the credit. It also provides a safe harbour for developers that invested at least five percent of the project cost by the end of 2019, which would allow such developers to retain eligibility, so long as they reasonably expected that the equipment would have been delivered within 105 days of purchase, regardless of subsequent events that prevented delivery from occurring on time. Developers will need to evaluate eligibility and conformity with such rules on a project-specific basis, see IRS Notice 2020-41.

Federal Level

At the federal level, the US Congress continues to develop and refine COVID-19 relief and stimulus packages. To date, the alternative energy sector has been largely omitted from receiving explicit and direct incentives or stimulus money. That being said, the COVID-19 pandemic has underscored the value of reliable electric, gas and communications infrastructure as critical networks that enable and facilitate personal, social and business relationships.

As furloughed or unemployed individuals seek new job opportunities, there is an emerging opportunity for governments to develop and support public works and core infrastructure development programs that may provide employment opportunities to help stabilise the market. One example of such a program is the House Democrats’ USD760 billion Moving Forward Framework, which calls for investment in core infrastructure projects. Many states have aging transmission and distribution infrastructure, among other things, that could benefit from such programs in a manner that would enhance the ability of the alternative energy sector to identify and develop cost-effective solutions to modernise the power grid.

While some states face budget constraints that may result in scaling back funds otherwise allocated to clean energy programs, at least one state has integrated alternative energy into COVID-19 recovery efforts. On 3 April 2020, New York State passed legislation, creating a new office of renewable energy siting to streamline and accelerate development and construction of renewable energy facilities. It also requires the development of distribution and local transmission system capital plans to accommodate rapid integration of variable renewable energy resources.

The wholesale electricity market is regulated by FERC, an independent regulatory agency within the US Department of Energy, which implements the FPA, NGA, NGPA and EPAct, among other statutes governing the utility industry. According to Section 201 of the FPA, the wholesale market encompasses all sales of electric energy made to any person for resale (16 U.S.C. Section 824). The FPA requires that all rates for wholesale sales of electric energy in interstate commerce be just and reasonable and not unduly discriminatory or preferential.

Setting Wholesale Rates

FERC oversees three methods for setting wholesale rates. First, Section 205 of the FPA, codified at 16 U.S.C. Section 824(d), requires public utilities to file their rates with the Commission.

Second, Section 206 of the FPA, codified at 16 U.S.C. Section 824(e), empowers FERC to, upon complaint or its own investigation, fix a new rate based on the cost of service when it determines that the existing rate is not just and reasonable or is unduly discriminatory or preferential; see

A third method of rate-setting in wholesale markets is by an avoided cost under PURPA. Under PURPA, certain co-generation and small power production facilities that meet specific operating and ownership standards may become qualified facilities, and their power output must be purchased by an electricity utility. An avoided cost is the cost of the power purchased from the qualifying facility that is lower than the cost of the energy that the buying utility would generate itself or purchase from another source. Qualifying facilities are determined by FERC and are commonly limited to sources whose primary energy source is wind, hydro, solar, biomass, thermal or waste resources. These types of wholesale sales receive special rates and regulatory treatment by FERC.

Bilateral contracts

Wholesale rates can also be set by the marketplace through bilateral contracts or power purchase agreements. Before an entity can make sales at such market-based rates, they must obtain market-based rate authority from FERC upon demonstration that the parties lack market power. FERC will review wholesale contracts to ensure that there is adequate competition in the wholesale market guaranteeing that contracts were freely negotiated. FERC also engages in oversight over wholesale markets by regulating the terms and conditions of wholesale market sales under FPA sections 205 and 206.

The US wholesale market is comprised of seven regional, centralised markets called RTOs and ISOs (collectively, RTOs/ISOs), and a patchwork of decentralised geographic areas that operate outside of a defined centralised operating authority.


FERC has encouraged creation of RTOs/ISOs, which have operational control, but not ownership, of transmission assets necessary to administer the wholesale markets. RTOs/ISOs are required to, among other things, maintain operation of the grid, and are subject to enforcement by the NERC (North American Electric Reliability Corporation), which is the FERC-designated electric reliability organisation of the USA The seven RTOs/ISOs serve two-thirds of the USA. Certain states in the South, Mountain West and Northwest did not join an RTO/ISO and continue to operate independently of the RTO/ISO wholesale markets in individual utility control areas where wholesale sales are made on a competitive basis primarily by power purchase agreements and bilateral contracts. The utilities in these control areas remain subject to certain aspects of FERC’s jurisdiction, and individual control area operators must co-ordinate amongst themselves to ensure region-wide service reliability. Certain service jurisdictions located in regions not within RTO/ISO regions have recently joined a quasi-RTO/ISO wholesale market called the Energy Imbalance Market.

In the seven RTO/ISO regions, wholesale prices are set by the centralised market using locational marginal pricing (LMP). LMP sets the marginal cost of energy for certain locations (or nodes) based on the operational characteristics of the nodal transmission system itself, incorporating the financial value of congestion, energy losses and the actual energy being transmitted. Security-constrained economic dispatch ensures least-cost energy is provided to each node by dispatching resources based on operational, reserve and transmission constraints to address reliability and system needs.

Sales outside the wholesale market

RTOs/ISOs also run capacity markets outside the traditional wholesale energy market to ensure reliable service through competitive auctions for capacity reserves. In capacity markets, generators will submit bids one year or more in advance to be paid for their willingness to provide electricity at any time within the year. This is done to ensure that there are generators and adequate capacity available at peak demand.

Certain sales within RTOs/ISOs may be made on a cost-of-service basis in limited circumstances where competition does not provide adequate price signals, or in non-RTO/ISO regions where a seller may not have market-based rate authority and thus, must provide power under FERC-regulated prices.

Transmission of electricity to a foreign country is regulated by FERC under Section 202(e) of the FPA (16 U.S.C. Section 824a(e)). Upon application, the Commission may grant an order to authorise the requested exportation of electric energy. The Department of Energy has authority over emergency authorisations of electricity transmission; see 16 U.S.C. Section 824a(c). Further, the Department of Energy oversees and is responsible for granting authorisation of importation and exportation of natural gas.

Electricity imported from a foreign country is not regulated by FERC or the Department of Energy, but by the state within which the importing facility is located; see 16 U.S.C. Section 824a(f).

In 2017, the USA imported a combined total of 65 million MWh (megawatt hours) of electricity from Canada and Mexico. Of that total, approximately 9% of that electricity came from Mexico, and 91% from Canada. Meanwhile, the USA exported a total of 9 million MWh of electricity to Mexico and Canada in 2017. Of that total, 65% was exported to Mexico and 35% to Canada. In 2018, the USA imported about 3.6% of its total annual electric energy consumption. For more information, see US Energy Information Administration (EIA).

The EIA estimates that, in 2019, approximately 4,118 billion kilowatt hours (kWh) of electricity was generated by utility-scale power plants of at least 1 MW in capacity, of which approximately 63% came from fossil fuels, with 20% from nuclear energy and 18% from renewable energy sources. An additional 35 billion kWh was generated in 2019 by small-scale solar photovoltaic systems under 1 MW capacity. The following is the relative contribution of each utility-scale fuel source to US electricity generation (see EIA):

  • Natural gas: 38.4%;
  • Coal: 23.5%;
  • Nuclear: 19.7%;
  • Renewable energy (total): 17.5% (comprised of 6.6% hydropower; 7.3% wind; 1.8% solar; 1.4% biomass; 0.4% geothermal).

According to the EIA’s 2020 Annual Energy Outlook, renewable energy is forecast to account for 38% of electricity by 2050.

The wholesale market concentration of electricity supply is regulated by a number of federal government agencies, principally FERC. FERC ensures competition in wholesale markets through, among other things, screening and authorising market participants that seek to make wholesale sales of energy, capacity and ancillary services at market-based rates. Negotiated rates will only be upheld if neither party has market power – the ability of one party to set prices above competitive rates due to their unilateral or coordinated ability to leverage undue influence on the market.

Market participants seeking market-based rate (MBR) authorisation must file an application and receive approval from FERC, which may be granted if the applicant can demonstrate that it lacks, or has adequately mitigated, horizontal and vertical market power. FERC, has adopted two screens for determining whether a party has horizontal market power: a pivotal supplier screen and a market share screen. Applicants that pass both screens are presumed to not have significant market power.

Applicants that fail one or both screens are presumed to have significant market power, but may rebut that presumption through mitigation efforts or by providing a Delivered Price Test analysis. FERC Order 861 recently revised the requirements applicable to MBR sellers in certain RTO/ISO markets, allowing a seller to forego submittal of indicative screens by indicating compliance with FERC-approved market monitoring measures adopted by RTOs/ISOs. FERC also announced the creation of a new regional database to track MBR sellers’ affiliates and owners that will rely on new data collection requirements implemented pursuant to Order 860.

Pivotal Supplier Screen

The pivotal supplier screen is used to determine whether a supplier is pivotal to the market. A supplier passes the pivotal supplier screen if its uncommitted capacity is less than the net uncommitted capacity in the market. In other words, this screen asks whether capacity from other entities, including imports, will be sufficient to meet wholesale demand in the market absent influence from the party being screened. The market share screen calculates a supplier’s share of uncommitted capacity in the wholesale market, and if the supplier’s share of uncommitted capacity exceeds 20% of the uncommitted capacity of the entire market, the supplier fails the screen and is deemed to have market power.

FERC Regulations

Market-based rate sellers must also demonstrate that they do not have vertical market power. FERC has determined that when an applicant owns, operates or controls transmission facilities, a FERC-approved Open Access Transmission Tariff (OATT) adequately mitigates vertical market power. As such, a market-based rate applicant must either be bound by a FERC-approved OATT or receive waiver of the OATT requirement, and certify that it has and will not create barriers to entry into the relevant market in order to demonstrate a lack of vertical market power.

FERC also regulates wholesale market concentration by overseeing mergers and acquisitions of public utilities to ensure that the merger’s effect on competition, rates, regulation and cross-subsidisation is consistent with the public interest. Section 203 of the FPA mandates that public utility mergers, consolidations, acquisitions, sales and leases be authorised by the Commission. Certain transactions are only subject to FERC authorisation if in excess of USD10 million; 16 U.S.C. Section 824b.

Pursuant to the EPAct, when ensuring that a transaction is consistent with the public interest, FERC must also ensure that a proposed transaction will not cross-subsidise any non-utility or associated company, or that such cross-subsidisation is consistent with the public interest.

Herfindahl-Hirschman Index

FERC relies on the Herfindahl-Hirschman Index (HHI) – a commonly accepted measure of market concentration – to determine whether the proposed transaction will increase market concentration to exceed the relevant market’s threshold concentration levels. To determine when a merger and acquisition transaction will have an anti-competitive effect – or increase market concentration above acceptable levels – FERC uses the HHI and its Merger Policy Statement (MPS), issued in 1996, to analyse the transaction. Used across industries, the HHI is a widely accepted measure of market concentration, calculated by squaring the market share of each firm competing in a given market, and summing the results. The MPS articulates methods for further computing market concentration, identifies safe harbour concentration levels and outlines the methods to be undertaken if a transaction failed either screen, see related guidelines.

DOJ Reviews and State Commissions

Energy industry mergers and acquisitions are also subject to review by the Department of Justice (DOJ) and the Federal Trade Commission (FTC). While FERC’s review of mergers and acquisitions is a relatively straightforward public interest inquiry, the DOJ and FTC will typically follow their 2010 Horizontal Merger Guidelines (HMG) for a more complex analysis. DOJ and FTC authorisation may still be required upon FERC’s approval of a transaction, see related guidelines.

State utility commissions may also have jurisdiction to review public utility merger and acquisition transactions. However, instead of focusing on the wholesale market, their review focuses on the impact on retail rates and the public interest.

The EPAct significantly augmented FERC’s authority to prohibit market manipulation, anti-competitive behaviour, and fraud. FERC remains the primary authority overseeing competition in the wholesale electricity markets, while a variety of other federal agencies, such as FTC or DOJ, may also have jurisdiction over electricity market participants, particularly over antitrust violations and criminal behaviour, as part of their generalised authority to regulate anti-competitive behaviour across a variety of market sectors in the USA.

Manipulation and Deception

In the EPAct, Congress enhanced and added sections to the FPA, NGA and NGPA, which prohibit manipulative or deceptive practices and provided for maximum civil penalties of USD1 million per day, per violation of rules, regulations and orders issued under those acts. It also expanded FERC’s authority with respect to anti-competitive behaviour by expressly prohibiting fraudulent or manipulative acts by “any entity” in the sale or purchase of electric energy or sale or purchase of transmission services – not merely entities providing service under FERC-approved market-based rate authority; see 16 U.S.C. Section 824v. The EPAct also expanded the scope of criminal provisions provided in the FPA and NGA by increasing the maximum fines and imprisonment sentences when FERC refers a case to DOJ to pursue a criminal prosecution.

FERC implemented its authority under the EPAct by promulgating the Anti-Manipulation Rule in Order No 670 in 2006. The Anti-Manipulation Rule broadly defines market manipulation to include conduct such as:

  • using or employing any device, scheme or artifice to defraud;
  • making untrue statements or omitting to state material facts; or
  • engaging in any act, practice or course of business that would operate as fraud or deceit upon another entity – see 16 U.S.C. Section 824v.

For market surveillance and enforcement, FERC has an Office of Enforcement (OE), which is comprised of scientists, engineers, attorneys, auditors, financial analysts and energy analysts. The OE has four divisions: the Division of Investigations; the Division of Audits and Accounting; the Division of Energy Market Oversight; and the Division of Analytics and Surveillance. Each division oversees a variety of functions, including ensuring compliance from market participants, initiating and executing investigations, providing warning of vulnerable market conditions, maintaining an Enforcement Hotline to informally resolve disputes, and advising the Commission on enforcement and compliance issues.

Ensuring Competitive Markets

Further, ISOs and RTOs have a significant role in ensuring competitive wholesale electricity markets by employing market monitors to detect market manipulation. Each ISO/RTO has approved of Market Monitoring Plans, which implement a variety of activities designed to assess and improve wholesale electricity market competition. Similar to the functions of FERC’s OE, RTO/ISO monitoring system functions include monitoring and ensuring compliance with market rules and procedures; gathering data; evaluating and reporting on market performance; proposing rule changes to improve market operation and performance; and, in some cases, employing mitigation measures and sanctions where authorised. Strengthening the role of these market monitors, under 18 C.F.R. Section 35.41(b), market participants must provide accurate information, and must not submit false or misleading information or omit material information to market monitors.

For additional guidance on FERC’s Anti-Manipulation Rule, see FERC Order No 670.

While the USA lacks a unified comprehensive federal approach to climate change, a number of federal and state laws and programmes are directed at limiting carbon emissions and advancing clean energy deployment. Holistic, market-based approaches to address climate change at the federal level have been debated for decades, but have not been adopted.

In the USA, Congress has the authority to address climate change through legislation and appropriation of funds, while the executive branch implements existing law through regulation and development of programmes. The primary federal laws regulating aspects of climate change and the power industry are the Clean Air Act (CAA) (42 U.S.C. Section 7401), the EPAct, the Consolidated Appropriations Act of 2016 and the Energy Independence and Security Act (42 U.S.C. Section 152).

The Clean Air Act

The CAA was enacted by Congress to protect the public health and welfare from a number of common air pollutants that come from a variety of pollution sources, such as industrial manufacturing, vehicles and electricity consumption. The CAA requires the EPA to implement rules and regulations to reduce the emission of such air pollutants, including carbon dioxide and methane. The EPAct regulates energy production in the USA, including renewable energy, energy efficiency, nuclear energy and security matters, oil and gas, and electricity.

Significantly, the EPAct provides tax incentives and loan guarantees on infrastructure development for particular energy sources.

The Consolidated Appropriations Act

The Consolidated Appropriations Act of 2016 retroactively reinstated and extended several renewable energy tax incentives for certain renewable sources, including the Production Tax Credit (PTC) and Investment Tax Credit (ITC).

The Energy Independence and Security Act

The Energy Independence and Security Act of 2007 was enacted with the goal of improving vehicle fuel economy and reducing US petroleum dependence by increasing renewable energy fuel sources. Among other things, the Energy Independence and Security Act: provides for funding research in renewable energy and carbon capture technologies; implements a biomass fuel standard; and mandates an increase in energy efficiency of new buildings, products and vehicles.

State Legislation

In the absence of a comprehensive federal climate change policy, a number of individual states have enacted legislation aimed at curbing greenhouse gas emissions and advancing clean energy deployment. Over 30 states have adopted legislation with the goal of addressing climate change. While each state takes a different approach, many have generally taken a market-based or performance-standard approach.

Current state legislation includes greenhouse gas emission targets, carbon pricing such as cap and trade policies, electricity portfolio standards, energy efficiency and decoupling policies, and transportation policies such as low-carbon fuel standards. Some states have grouped together in co-operative agreements, such as the Regional Greenhouse Gas Initiative (RGGI), wherein carbon emissions from fossil power plants 25 MW or larger are capped and traded in regional carbon allowance markets.

International Agreements

In addition to state and federal regulations affecting climate change, the USA has signed a number of international agreements that seek to address climate change. The latest in a series of international agreements on climate change, within the United Nations Framework Convention on Climate Change, is the Paris Agreement of 2015 (Paris Agreement). Pursuant to the Paris Agreement, the USA set targets to reduce greenhouse gas emissions to 17% below 2005 greenhouse gas levels by 2020, and 28% below 2005 levels by 2025.

In 2015, the Obama administration’s EPA promulgated the CPP, which leveraged EPA’s authority under the CAA to establish greenhouse gas emission reduction targets for each state and would have required each state to promulgate a state-specific plan to meet its target. However, in February 2016, a divided Supreme Court issued a rare stay on the implementation of the CPP and in June 2019, the EPA, under the Trump administration, replaced the CPP with the ACE. ACE provides states with new emission guidelines for developing performance standards on carbon emission reduction from existing coal-fired electric generators. While the CPP would have set emissions caps for each state, ACE takes a narrower approach by recommending efficiency improvements for individual power plants.

State Legislation

At the state level, various forms of legislation have been implemented to address carbon emissions and encourage early retirement of carbon-based generation. A number of states have entered into a RGGI, a market-based initiative to cap and reduce the power sector’s carbon emissions. Based on the RGGI Model Rule, each participating state has a Budget Trading Program comprised of carbon emissions limits and allowance auctions.

In RGGI states, fossil-fuel-fired electric generators that have a capacity of 25 MW or greater must hold allowances equal to that of their carbon emissions for a three-year period. Each year, the carbon emission allowance cap is reduced by 3% until 2020. Post-2020 cap levels have been established in RGGI’s Model Rule Amendments. The proceeds from allowance auctions are invested in energy efficiency and renewable energy resources.

While RGGI rules only apply to electric generating facilities, California has a similar programme that applies to a broader range of carbon-emitting facilities.

Market legislation

Another market-based state legislative approach to reducing carbon emissions is demand-side management (DSM) and/or non-wires alternatives (NWA) programmes. These programmes are designed to encourage electric utility consumers to modify their electricity consumption patterns. DSM can reduce peak demand and smooth load curves to decrease reliance on fossil-fuel-fired electric generators, while NWAs can defer or replace the need for traditional utility investments.

Facility Retirement Rules

Additionally, RTOs and ISOs have rules regarding the retirement of generating facilities. Facilities necessary for reliability are not retired before the loss of electric energy can be replaced. There are several considerations that go into retiring a generation facility, including the age of the generating unit, capital and operating costs, market conditions, environmental restrictions and compliance costs.

While FERC does not have authority over the retirement of most generation facilities, the Commission does mandate reliability standards under FPA Section 215; see 16 U.S.C. Section 824o. As such, RTOs and ISOs must assess the reliability of a retiring generating facility, and if applicable, can compensate units that are required to run past their preferred retirement date through reliability-must-run contracts.

The ICT and the PTC

The most significant federal incentives that encourage alternative energy development are the ITC and the PTC. As amended by the Consolidated Appropriations Act of 2015, the ITC provides a 30% tax credit for solar technologies, fuel cells and small wind turbines installed on residential and commercial properties. The ITC also provides a 10% tax credit for installed geothermal, microturbines, and combined heat and power systems.

The PTC provides a tax credit for electricity generated by qualified energy resources and sold by the taxpayer to an unrelated person.

For wind, geothermal, closed-loop biomass and solar systems not also claiming the ITC, the tax credit is USD0.023 per kWh, and for other eligible technologies is USD0.012 per kWh. These rates are administrated by the Internal Revenue Service, and are adjusted for inflation based on 1993’s USD0.015 per kWh rate. The percentage tax credit available under the ITC is being reduced annually.

While the PTC provides credits based on the amount of energy generated by qualifying facilities, the ITC credits are based on the upfront capital expenses of building and installing qualifying facilities. The PTC originally expired at the end of 2013, but was extended first by the Tax Increase Prevention Act of 2014, then by the Consolidated Appropriations Act of 2016. This allowed PTC-eligible facilities to claim the ITC tax credit in lieu of the PTC through the end of 2016, and the end of 2019 for wind facilities. Based on the technology, the largest tax credit available to developers after 2022 is 22%, and some technologies may no longer qualify for the ITC.

Renewable Energy Standards

Another significant driver of renewable energy deployment are state-enacted Renewable Energy Portfolio Standards (RPS), variations of which have been implemented by 36 states plus the District of Columbia, for example, see New York, California, and Vermont. An RPS is a state mandate requiring that a particular percentage of energy supply to retail customers be from renewable energy sources. The elements of an RPS programme vary by state as to which resources are eligible, how retail sales are measured, which types of utilities are subject to the mandate, whether there are cost caps to limit customer bill impact, and so on.

Utilities subject to RPS mandates may either build qualifying renewable energy generation, purchase RECs, or pay alternative compliance payments and/or penalties. A growing number of states have recently enacted legislation creating ZEC programmes in which subsidies are provided to non-economic nuclear generation units. While structurally different depending on the state, ZEC programmes are generally closed markets in which ZECs are assigned to particular nuclear generating facilities to provide a stable income stream rather than to incentivise build-out of alternative energy resources.

PACE Programmes

Property-assessed clean energy (PACE) programmes are another model for innovative renewable energy financing. PACE programmes are created by cities or counties that designate a financing district, whereby property owners may voluntarily sign up for financing to install energy projects or make renewable energy improvements on their property. PACE financing allows property owners to make improvements without large upfront expenses.

Property owners gradually repay improvement or installation costs over a set period of time, which are secured by the property itself and paid as an addition to the property owner’s tax bills. Repercussions for non-payment are the same as those for failure to pay property taxes, and any subsequent owner to the land must be willing to fulfil the obligations of the property owner upon sale or transfer of the land. For further information on PACE programs, see the Department of Energy’s Office of Energy Efficiency and Renewable Energy.

The system of laws applicable to the construction and operation of generation facilities varies depending on the type of facility and its location. For the purposes of this discussion, distinction is drawn between offshore facilities and onshore facilities.

Onshore Generation Facilities

State law will be the primary authority for the construction and operation of onshore generation facilities. Applicable laws generally take the form of:

  • public utility law regulatory authorities;
  • local/state permitting laws; and
  • state environmental review laws.

In the first category, some states require that electric generating facilities obtain a Certificate of Public Convenience and Necessity (CPCN) or similar approval for generating facilities prior to construction and operation under the state’s public utility laws.

In the second category, local permitting may be required from the municipality where a facility will be sited in the form of a special use permit or similar approval under local zoning laws. In some states, permitting is governed by a centralised ("one-stop") siting board that may supersede some or all local permitting authorities. These are intended to streamline the permitting review process.

In the third category, various state environmental review acts (or mini-NEPAs) apply, which generally resemble the federal NEPA. If a federal permit is involved and the project may result in discharge into waters of the USA, a Clean Water Act (CWA) Section 401 Water Quality Certification will be necessary.

Federal authority

Projects may also implicate federal authority. Specifically, where onshore projects involve federal lands, authorisation from the United States Department of Interior (DOI), Bureau of Land Management (BLM) or United States Forest Service may be required. Depending on potential impacts, involvement by various consulting agencies may be necessary under the Endangered Species Act, Migratory Bird Treaty Act, Bald and Golden Eagle Protection Act, and the Clean Water Act. Where federal action is involved, environmental review under NEPA will also be necessary.

Offshore Generation Facilities

Offshore generation facilities are routinely being proposed in the offshore areas of coastal states throughout the country. The Block Island Wind Farm – the country’s first offshore wind farm – began operating off Rhode Island in 2016. The applicable laws for offshore facilities can be divided based on whether they are proposed for federal waters or state waters.

Pursuant to the Submerged Lands Act of 1953, 43 U.S.C. Section 1301 et seq, states regulate coastal waters in the areas within three miles from shore. Federal regulatory authority is applied beyond that point to the limits of the USA’s jurisdiction. Section 388 of the EPAct gave the US Secretary of the Interior authority over offshore renewable energy facilities (including all energy resources other than oil and gas and minerals) in federal waters. In general, the DOI, Bureau of Ocean Energy Management (BOEM) issues leases, easements and rights of way for renewable energy development in federal waters pursuant to its regulations.

Projects also typically require approval from the United States Army Corps of Engineers under Section 10 of the Rivers and Harbors Act (RHA) (obstructions to navigation in "navigable waters") and Section 404 of the CWA (discharge of dredged or fill material). As with onshore facilities, offshore federal actions that may affect the environment require compliance with NEPA. In some cases, federal agencies have prepared programmatic environmental impact statements that are intended to streamline the environmental review process.

State laws

For offshore facilities within state jurisdiction, construction and operation of renewable generation projects will be governed by applicable state laws, including a state’s "mini NEPA", which generally provides for review, analysis and sometimes mitigation of environmental impacts associated with government action. State laws may also provide for the necessary easement, lease or other right to use state-owned land underwater. On the federal side, such projects require federal RHA Section 10/CWA Section 404 permitting (due to installation of facilities in navigable waters), which will also trigger compliance with NEPA. Finally, a CWA Section 401 State Water Quality Certificate will be needed for projects that require RHA Section 10/CWA Section 404 permits.

Federal Projects

For federal projects requiring an environmental impact statement under NEPA, several recent federal streamlining provisions may apply. Executive Order 13807 creates a framework for "One Federal Decision" and sets an average time frame of not more than two years for an EIS process. DOI Secretarial Order 3355, issued in response to Executive Order 13807, sets a page limit of 150 pages (300 for complex projects) and a one-year timeline for EISs. Both orders are broadly applicable to “infrastructure projects”, which includes renewable energy.

As noted, local, state and federal approvals may be required to construct and operate electric generation facilities. In many states, the applicant will need a CPCN or its equivalent from the state utility commission. As part of the CPCN proceeding, or as a separate process, an applicant will likely be subject to review by a multitude of state agencies and authorities, including the relevant counties and municipalities, drainage districts, state natural and environmental agencies, transportation authorities and cultural heritage preservation offices.

The approval process will vary by state. The CPCN may include authority to exercise eminent domain for the purposes of the project. In some states as noted, a centralised "one-stop" siting board is in place that is intended to streamline the siting approval process. Some projects may include regulatory approvals on the federal side where sited on federal lands or where federal programmes are triggered, such as CWA Section 404 (for discharges of dredged or fill material).

State, local and federal agency approval of generation facilities is contingent upon the terms and conditions as determined by the applicable agencies in the review process. As discussed previously, a company seeking a generation facility permit must undergo review by numerous authorities, which may include local, state and federal agencies/authorities. During such review, the applicable authorities often condition their approvals upon certain modifications or considerations intended to bring the proposed project into compliance with the relevant permitting standards, or otherwise reduce impacts that are of concern to the regulators.

A CPCN issued by a state public utility commission will often include eminent domain rights to the facility developer under terms and conditions specific to that state and its relevant laws. To act on their eminent domain authority, the developer must provide the landowner with just compensation based on the fair market value of the property being condemned on the date that the eminent domain is exercised. Typically, a court will determine the just compensation value of the condemned property.

Decommissioning is often included as part of the terms and conditions of approval for generation facilities. The specifics of such requirements and how they are implemented are highly dependent on the local, state or federal authorities involved, and their unique practices. Permitting authorities may require formal decommissioning plans and financial security.

In some cases, decommissioning requirements are applied based on discretionary approval conditions, while in other cases, specific legal requirements for decommissioning may be derived from applicable laws or regulations.

The US transmission system is comprised of facilities that are privately, publicly, federally or co-operatively owned. While individual states have primary authority over siting and construction of electric transmission lines and their associated facilities, federal authorities are involved in circumstances where a project is located on federal lands, spans multiple states or in certain designated areas.

The EPAct enhanced co-ordination and communication among federal agencies with authority to site electric transmission facilities by, among other things, directing the DOE to co-ordinate all federal authorisations and related environmental reviews needed for siting interstate electric transmission projects; see EPAct 2005 Sction 1221(a), which added Section 216(h) to the FPA, codified at 16 U.S. Code Section 824p. DOE has authority to identify certain National Interest Electric Transmission Corridors, within which FERC has authority in certain circumstances to grant permits for transmission facility applications. FERC may also grant transmission facility permits when it finds that a state does not have authority to do so, the state commission withholds approval for more than a year after filing, or the facilities to be authorised will provide electric energy transmission in interstate commerce. FERC may grant a permit upon finding that the proposed construction is consistent with the public interest, will reduce congestion, is sound with the national energy policy or will maximise transmission capabilities of existing facilities.

Under the FPA, the Secretary of the DOE has emergency authority to require temporary connections of generation, delivery or transmission electricity facilities that will best meet the emergency and serve the public interest; see 16 U.S.C. Section 824a(c).

Both state and federal certifications and approvals are generally required to construct and operate electric transmission facilities.

State Approval

Some states may have a pre-filing consultation requirement designed to co-ordinate the review process across multiple agencies. Ultimately, the applicant will generally need to obtain a CPCN, or an equivalent certificate, from the state utility commission. As part of the CPCN proceeding, or as a separate process, an applicant will likely be subject to review by a multitude of state agencies and authorities, including the relevant counties and municipalities, drainage districts, state natural resource and environmental agencies, transportation authorities and cultural heritage preservation offices.

These approval processes will vary by state. The CPCN may include the authority to exercise eminent domain for the purpose of building transmission lines.

Federal Approval

In addition to state permits and authorisations, an applicant will likely need to obtain approval from several federal agencies, including the US Army Corps of Engineers, the Federal Aviation Administration, the US Fish and Wildlife Service, the Department of Agriculture, the Department of Commerce, the Department of Defense, the DOE, the EPA, the Council on Environmental Quality, the Advisory Council on Historic Preservation, the DOI and FERC. Eight of these federal agencies entered into a Memorandum of Understanding (MOU) in October 2009 to improve co-ordination among project applicants, federal agencies, and states and tribes involved in the siting and permitting process. The MOU designates a "lead agency" as a single point of contact, which will co-ordinate all federal reviews necessary to the approval of the development and siting of the proposed facilities. For more information, see the Department of Energy’s Office of Electricity.

Permit Review

When a company’s permit application is subject to review by FERC, the company must meet with the Commission’s Director of Energy projects to initiate the pre-filing review process. Upon approval from the Director, the Commission will issue a notice of the pre-filing process and the company must implement a Public Participation Plan to identify how it intends to communicate with stakeholders and disseminate information to the public. During this pre-filing stage, Commission staff will assist the company in preparing their complete application by conducting site visits, facilitating the identification and resolution of issues, and initiating environmental review of the proposed project.

Once the company files a complete application, the Commission will review comments and recommendations from involved entities and individuals, hold public meetings and technical conferences, and clarify project-related issues. The Commission is required to act upon an application within one year of the filing date. In addition, FERC will issue a Notice of Intent (NOI) to prepare an environmental assessment (EA) or environmental impact statement (EIS).

The NOI is sent to federal agencies, state and local agencies, and any entity or individual that may be affected by the transmission facilities, seeking comments from interested parties. After the comment period, FERC will prepare an EA or EIS to outline its findings and recommendations. FERC will address the comments in the EA or EIS, or in the final order granting or denying the application. The extent of the federal review process will depend on a number of factors, including the size and location of the project and the degree of coordination between the federal agencies and the applicant.

State, local and federal agency approval of transmission facilities is contingent upon the terms and conditions as determined by the applicable agencies in the review process. As discussed previously, a company seeking a transmission facilities permit must undergo review by numerous authorities, both state and federal. During such review, the applicable authority will make comments and recommendations and will condition their approval upon certain modifications or considerations that will bring the proposed project into compliance with the relevant safety, environmental, engineering and zoning standards.

State Level

A CPCN (or its equivalent) issued by a state public utility commission will often include eminent domain rights to the transmission facility developer under terms and conditions specific to that state. To act on their eminent domain authority, the developer must provide the landowner with just compensation based on the fair market value of the property being condemned on the date that the eminent domain is exercised. Typically, a court will determine the just compensation value of the condemned property.

If applicable state law limits a developer’s eminent domain authority, the federal authority overseeing the eminent domain proceeding is equally constrained; see FERC Order No 689, Sections 225–227.

Federal Level

On the federal level, if a facility project is granted a permit by FERC or the DOE, the transmission facility developer will have eminent domain authority; see 16 U.S.C. Section 824p. The eminent domain authority can only be used for the permitted facilities. In using eminent domain, the developer should provide the landowner with basic information concerning the eminent domain process.

The developer should refer the landowner to the relevant state agency or state Attorney General and should explain to the landowner that they have the right to acquire the property, or property rights, by eminent domain under FPA Section 216(e).

Under federal law, transmission entities do not have monopoly rights to provide transmission service within a specific geographic area. While historically transmission lines were owned by private, vertically integrated entities, FERC required transmission services to be unbundled and provided pursuant to each utility’s FERC-approved Open Access Transmission Tariff, which sets forth the terms and conditions of using the transmission system; see FERC Order Nos 888, 889, 890.

In 2011, FERC Order No 1000 built upon Order 890 to increase transmission development by requiring public utility transmission providers to participate in a regional transmission planning process to generate regional transmission plans. It also required improved co-ordination between neighbouring transmission planning regions for the siting of new interregional transmission facilities.

While federal law does not provide for monopoly transmission rights, state law and utility commission regulation may provide for such rights under terms and conditions that will vary by state.

Pursuant to the FPA, FERC has exclusive jurisdiction over transmission of electric energy in interstate commerce, the sale of electric energy at wholesale in interstate commerce, and over all facilities for such transmission or sale of electric energy. This jurisdiction is conferred by Section 201 of the FPA, and the principal laws of such jurisdiction are encoded at 16 U.S.C. Section 824, 824(d), and 824(e). Utilities providing transmission service subject to FERC’s jurisdiction must receive and abide by an OATT, which unbundles transmission operations and services and sets forth rates for transmission and ancillary services.

Transmission providers must publish service, rates and available capacity, as well as rules and standards related to their transmission services on the Open Access Same-Time Information System (OASIS). FERC has authority to review and ensure rates and terms of transmission service are just and reasonable and not unduly discriminatory of preferential.

A detailed listing of these laws can be found on the website.

FERC determines the rates, terms and conditions of service for transmission of electric energy in interstate commerce. As required by the FPA, FERC ensures that transmission rates are just and reasonable, and that public utilities are not unduly preferential or advantageous to any entity by charging different rates to similarly situated transmission customers.

Wholesale rates are set according to Sections 205 and 206 of the FPA. A rate case can be initiated by a utility filing for a rate change, by complaint from another person or entity, or by FERC’s own initiative. Upon hearing, FERC will determine whether the utility’s proposed rate is just and reasonable or make appropriate modifications to the rate as necessary; see 16 U.S.C. Section 824e. Section 205 of the FPA requires that utilities filing for a rate change give the Commission 60 days’ notice prior to the proposed date that the modification take effect.

Establishing Rates Through Formulas

FERC’s policy is to permit utilities to establish rates through formulas. FERC will generally approve of or formulate new rates that are based on the utility’s cost of service to balance the interests of the utility and its customers. Under this approach, the aggregate costs – such as the reasonable return on investment – for providing each class of service are determined, and prices are set to recover those costs. FERC generally uses the following formula, derived from a 12-month test period, to determine cost of service: E+d+T+(V - D)R, where:

  • E = operating expense – utilities are generally entitled to recover prudently incurred operating expenses that relate to the provision of wholesale service;
  • d = depreciation expense – depreciation means the loss in service value not restored by current maintenance that is incurred in the course of service;
  • T = taxes – certain tax expenses associated with cost of service revenues;
  • V = gross value of property – facility cost plus including working capital;
  • D = accrued depreciation – depreciation of assets;
  • R = overall rate of return – sufficient to allow the utility to maintain financial integrity, attract additional capital and earn a return comparable to similarly situated companies.

In May 2020, FERC issued Opinion No 569-A, which accepts the use of an alternative model – the “Risk Premium Model” – for determining whether a rate of return on equity is just and reasonable under Section 206 of the FPA.

Rehearing the Case

If any party to a FERC hearing was aggrieved by or does not agree with the result of FERC’s order on the hearing, that party may request that FERC rehear the case. The rehearing request must be submitted within 30 days from the original order, and the Commission does not have the authority to extend this deadline. If the Commission does not act on the request for rehearing within 30 days, the request is deemed denied.

After FERC issues an order upon rehearing, the parties to the hearing have the right to petition the United States Court of Appeals for review of the order, typically to the United States Court of Appeals for the District of Columbia Circuit, or the jurisdiction in which the utility has its principle place of business.

FERC has authority to intake and resolve complaints by assigning the case to alternative dispute resolution, issuing an order on the merits based upon the pleadings or establishing a hearing before an Administrative Law Judge. The Commission’s decision on whether to conduct a formal evidentiary hearing on issues raised in complaints is generally discretionary.

Pursuant to a series of FERC Orders first promulgated in 1996, transmission services must be provided on a non-discriminatory and open-access basis.

Starting with the EPAct, which encouraged FERC to foster competition in wholesale energy markets, FERC issued three key orders to require open access to transmission facilities. Order No 888, issued in April 1996, required all public utilities that owned, controlled or operated facilities used for transmitting electric energy in interstate commerce to file OATTs. Order No 888 permitted public utilities and transmitting utilities to seek recovery of legitimate, prudent and verifiable stranded costs associated with providing such open access.

Order No 889 required all public utilities that own, control or operate facilities used for transmitting electric energy in interstate commerce to participate in an OASIS to provide actual and potential open access transmission customers with information that would enable them to obtain open access non-discriminatory service. Transmission providers must publish service, rates and available capacity, as well as rules and standards related to their transmission services on OASIS.

FERC Order No 890 was issued in February 2007 to strengthen the OATT, reduce opportunities for undue discrimination, facilitate the Commission’s enforcement and increase overall transparency in transmission system planning and use.

Issued in July 2011, Order No 1000 amended Order 890 by requiring public utility transmission providers to participate in a regional transmission planning process that produces a regional transmission plan in order to improve coordination between neighbouring transmission planning regions.

The distribution system is primarily governed and regulated at the state level. State law and state utility commission regulations govern the methods and standards by which prudent distribution system investments are recovered in a utility’s rate base or through other appropriate mechanisms. Construction, siting, zoning and other land use considerations and approvals generally fall within the purview of relevant city, county, and municipal authorities, which significantly vary by state.

While the substantive and procedural regulatory process for constructing and operating distribution facilities varies by state, state utility commission regulations generally focus on compliance with reliability, operational and safety standards. While some state utility commissions have authority over the siting and approval of permits for construction of distribution infrastructure, most states require the involvement and/or approval of multiple agencies, beyond the state utility commission, to review environmental, cultural, historical, technical and economic impacts.

Generally, FERC plays a limited role in distribution infrastructure development, only becoming involved to the extent there is a jurisdictional question regarding the facility’s status as a distribution or transmission facility, or if the facility implicates a federal law under the purview of FERC’s jurisdiction.

Public Participation

Public participation and input may be permitted in accordance with applicable state and local laws. Similar to the federal processes, state law may require a public hearing, and the overseeing state agency or state utility commission may solicit public comments on the proposed distribution facility. Most state utility commissions have an online public docketing portal wherein applications, notices, comments, petitions, rulings and orders are posted.

Depending on the state and the type of distribution facility being proposed, a utility or developer may need to file advance notice of a proposed facility, which may be subject to public comment. Timing of distribution system approvals may depend on state-specific public notice and comment requirements, utility rate case schedules, local government involvement, and state policy and regulation.

The terms and conditions of distribution facility approval vary based on state regulations and market structures. In vertically integrated states, a state utility commission typically requires the distribution facility applicant to demonstrate that a facility is necessary, prudent, in the public interest, and just and reasonable in light of current market conditions and state policy objectives. Approval may be conditioned upon compliance with certain safety, environmental, engineering and public interest standards.

The power of eminent domain, condemnation and expropriation is commonly granted to electric energy distribution facility applicants upon review and approval of their construction and operation application. However, depending on the applicable state laws governing eminent domain, the rights of the distribution facility applicant will vary.

A distribution facility or utility exercising its right of eminent domain must provide just compensation for the property being condemned. The fair market value of the property being taken, or just compensation, will vary by state and may be determined by a state court.

In most states, utilities have geographically defined service territories, provided for by state legislation or regulation, within which the utility has monopoly rights to provide distribution service. Exceptions may exist in some states for competitive market participants depending on state law and regulation. The degree to which monopoly service rights exist, the extent of deregulation, the method by which such rights are modified and the opportunity for competitive market participants to compete within those service territories significantly varies by state.

The primary authority over electric energy distribution is each state’s utility commission, which typically has broad authority to ensure just and reasonable rates, terms and conditions of distribution service in accordance with state legislation, regulation and promulgated rules.

FERC imposes a functional test for the case-by-case determination of whether a facility is providing interstate transmission service or local distribution service, but generally defers to states’ interpretation and application of those factors in making its determination. State utility commissions have jurisdiction over rates and terms of service for retail distribution level utility service. Generally, the rate-making process is designed to balance the utility company’s opportunity to earn a fair return on its investments and the customer’s interest in receiving safe, reliable service at just and reasonable rates.

State Utility Commission

For utilities with rates that are regulated by a state utility commission, rates are generally set through regulatory proceedings following submittal of a request to increase base rates along with written supporting testimony and evidence. The state utility commission, along with interested parties that seek to intervene, may propound interrogatories and/or requests for information on the utility and vice versa. Generally, parties will brief their positions and the rate case may settle if a sufficient number of parties agree to a joint settlement, or the case may proceed to formal hearings.

In most states, the utility rate case documents are posted on a public docketing database, unless they are confidential or protected pursuant to state regulations and state utility commission rules. The process, frequency, duration and time-frame for rate cases depend on the state in which the distribution facility is located and the utility tariffs that seek to be modified, but the process generally ranges from eight to 12 months and results in an order covering one to three years.

Cost of Service Regulatory Model

Most states operate under a cost of service regulatory model whereby the regulator determines the utility’s revenue requirement that reflects the total amount that must be collected from customers in rates for the utility to recover its reasonable and necessary expenses, as well as earn a reasonable return on investment. The revenue requirement is generally derived through a formula that accounts for the utility’s rate base, a fair rate of return, operating costs, depreciation expenses, taxes and other costs. The treatment of electricity supply, among other items, will vary depending on the degree to which states have restructured their electric market.

While states may have different approaches to calculating a rate of return, the rate should be sufficient to maintain financial integrity of the utility, enable attraction of additional capital and be equal to that earned by other companies with comparable risk profiles. Depreciation rates are approved by state utility commissions upon review and consideration of depreciation studies, which are generally performed by depreciation consultants and supported with expert testimony in rate case proceedings. Some states have adopted alternative rate-making methodologies that are focused on incremental rate recovery, performance-based metrics and other adjustment mechanisms that vary by state.

Reconsideration of Utility Rates

Following issuance of a formal ruling or order on a utility’s rate request, a utility or interested party may request a rehearing or reconsideration depending on state law and regulation. Once a final agency determination has been reached, and all administrative remedies have been exhausted, an entity may appeal the decision to the applicable state court for judicial review.

State utility commissions may have rules or regulations governing the process for filing complaints and/or challenging existing rates and terms and conditions of service. Such complaints and challenges may be directed to utility consumer protection bureaus that serve as mediators to efficiently resolve disputes. The substantive and procedural elements of this process will vary by state.

United States Alternative Energy and Power Industry - Trends and Developments

Electric power markets in the United States have experienced a major shift over the last decade or more. Coal-fired generation, once the backbone of the US electric power supply, has steadily declined, replaced first by inexpensive natural gas (the product of advances in fracking technology), and increasingly by alternative energy sources: utility-scale wind and solar and distributed solar generation. In April 2019, the USA for the first time produced more electricity from renewable sources than from coal, according to the US Energy Information Agency (EIA).

The EIA further projected (before the disruption caused by COVID-19) that in 2020, coal-fired electricity generation would decline an additional 13%, while generation from alternative energy sources would grow by 15%.

National Policies Favouring Alternative Energy

Production Tax Credit

Utility-scale wind generation has grown most rapidly over the last two decades. Federal tax policy has been a significant driver, beginning with enactment of the Renewable Energy Production Tax Credit (PTC) in 1992. The PTC provides a tax credit for each qualifying kilowatt-hour (kWh) of electricity generated, for ten years after the generating source is placed in service.

Short term extensions of the PTC (it has been extended 12 times) have fostered repeated booms and lulls in wind development, as Congress allowed the PTC to expire several times, only to renew it retroactively. But in 2015, Congress adopted a plan to step down the PTC over several years and to end it after 2019.

The PTC is not gone yet – in late 2019, Congress added a year, allowing 2020 projects to receive 60% of the credit (2019 projects only get 40%). And, under so-called “safe harbour” rules, a project’s credit rate is based on when it began construction, as long as it comes online within four years (now extended to five years due to COVID-19). Thus, projects that qualify in 2020 will receive 60% of the PTC, if brought online by the end of 2024.

Investment Tax Credit

Alternatively, facilities eligible for the PTC can claim an “investment tax credit” (ITC), a percentage of the capital cost of construction instead of the per-kWh PTC credit. The ITC also is being phased out, in parallel to the PTC.

Congress enacted an ITC for residential and commercial solar generation in 2006. As with wind generation, the solar ITC has spurred rapid growth in solar-powered electricity generation. Congress extended the solar ITC in 2015, but projects that commence construction after 2019 will receive a reduced credit, stepping down from 30% to just 10% by 2022 for commercial and utility-scale projects, and ending for residential projects after 2021. During the last decade, the solar ITC has helped spur 50% average annual growth in residential and commercial solar generation.

As federal incentives for new alternative energy electric power generation are significantly reduced or phased out (at least under current legislation), other incentives are likely to have a greater impact on future growth in this sector – particularly actions by states and by corporate power purchasers.

State Actions

In the federal system, states are often regarded as the laboratories for experiment and the source of a patchwork of regulations. Because the federal government’s powers are limited to those enumerated in the Constitution, the states can harness their considerable police powers to either facilitate or inhibit the success of industry. The Alternative Energy and Power industry is no exception, particularly when one focuses on solar and wind and sets aside the hydroelectric industry that is regulated pursuant to broad federal authorities under the Federal Power Act.

State-specific renewable energy targets

Many states have developed renewable energy targets that provide an essential incentive for development of renewable energy within their borders. States began adopting Renewable Portfolio Standards (RPS) – a requirement that utilities obtain some quantity of their electricity from renewable sources – in the late 1990s. Today, 29 states have RPSs and eight states have renewable portfolio goals.

In recent years, several states have adopted new or updated standards that push their state electric systems toward 100% clean energy sources. For example, Virginia recently passed the Clean Economy Act, setting one of the largest energy storage targets in the country, pushing state regulators to devise a carbon dioxide cap, and including a RPS with interim targets set at 58% clean power by 2030, 73% by 2035, 88% by 2040, and 100% by 2050. Virginia joined California, Hawaii, Maine, New Mexico, Washington and the District of Columbia with 100% clean or renewable energy standards (to be achieved in 2045 or 2050), while Nevada and Colorado have set a 100% goal.

However, state law can pose significant obstacles to alternative energy development. The obstacles may be intentional or unintentional and can take many forms. Some are specific to the alternative energy industry.

For example, interconnection standards, which establish the rules whereby new generation facilities can connect to the existing electric grid, may facilitate or obstruct alternative energy development. At a smaller scale, metering policies may either allow customers who generate excess electricity to sell it or get credit for it on the market, or forbid them from doing so.

Land use and environmental regulations

Other obstacles to alternative energy development include state and local land use and environmental regulations. In general, local governments regulate local land use through zoning and other mechanisms. Two decades ago, few land use/zoning ordinances identified alternative energy development as a recognised land use.

While progress has been made toward identifying wind and solar projects as recognised land uses and identifying areas within local jurisdictions where such land uses are authorised, either as of right or with a permit, obstacles remain, for example to the co-location of energy storage with alternative energy generation.

Obstacles to development

The myriad of state environmental regulations may pose an obstacle to alternative energy development. These can range from the requirement to prepare environmental impact assessments to comply with state law, to requirements aimed at protecting farmland or wildlife. These regulations are often weaponised by project opponents in order to advance their parochial interests.

Historically, governments have found it difficult to combat the arguable abuse of environmental regulations by motivated project opponents.

Corporate Power Purchases

Large companies have increasingly become important alternative energy customers in the United States, and elsewhere. The number of Fortune 500 companies with 100% renewables goals grew from 23 in 2017 to 53 in 2018. Companies joining RE100, a global corporate initiative that began in 2014, set a public goal to source 100% of their global electricity consumption from renewable sources by a specified year.

In December 2019, RE100 passed 200 members. By June 2020, it had 235.

Corporations are increasingly meeting their commitments to renewable electricity by purchasing the power directly from generators through corporate power purchase agreements (PPAs). These long-term agreements, typically linked to the output from specific generating assets, provide the companies with stable power prices as well as green credentials. Corporate PPAs also play a key role in financing the development of alternative energy projects.

Electricity purchases

Electricity is purchased at a pre-agreed price structure for a set period, which provides certain cash flows for the project. Higher education is also becoming a major purchaser of alternative energy. In 2019, the Environment America Research and Policy Center reported that more than 40 colleges and universities obtain 100% of their electricity from renewable sources.

This is a rapidly growing market. In 2018, US corporate direct purchases of renewable power totaled 13.4 gigawatts (GW), double the volume in 2017. Bloomberg New Energy Finance estimates signatories to the RE100 initiative alone will need to fund around 102 GW of new solar and wind projects globally to meet their 2030 commitments.

Wildlife and Natural Resources

Utility-scale alternative energy projects face different permitting challenges from conventionally-fueled electricity generation. Wildlife and natural resource issues play a significant role in alternative energy project siting decisions. Advances in generating technology have allowed alternative energy projects to capture more energy cost-effectively, and the market demand for wind and solar projects has increased.

Consequently, renewable energy projects are being sited in new states and regions. As more and more projects appear on the landscape, “easy” sites have become scarce. The complexity of wildlife and natural resource issues varies depending upon the ecological and legal setting.

Through the Central Plains, migratory birds dominate wildlife conversations. In the Midwest and Northeast, bat species are a significant concern. For solar energy, terrestrial species drive siting concerns.

Endangered species

Even though most alternative energy projects occur on private lands, development on federal lands or with a federal nexus can trigger Endangered Species Act (ESA) review. Increasingly, alternative energy projects, particularly solar projects with larger footprints, are finding it more and more difficult to avoid impacts to other natural resources, such as “Waters of the United States” governed by the Clean Water Act. Obtaining permitting under these other natural resource statutes triggers review under the ESA, which can add time and cost to project development.

States, too, have their own wildlife permitting programs. California, New York and Illinois, for example, have their own endangered species act statutes and permitting programs.

Fish and wildlife

The US Fish and Wildlife Service (USFWS) is considering whether to grant protection under the ESA (ie, "list") many species that may be found over a large range, such as the little brown bat, the lesser prairie chicken and the monarch butterfly. USFWS maintains a workplan that it uses to help organise its “calendar” of listing decisions, which includes these three species, among many others. If listed, these species will require assessment across great swaths of the United States.

However, localised, longstanding listed species such as the Houston toad may not be distributed widely, but still can complicate project development due to uncertainties surrounding their habitat.

Bald and golden eagle protection

Beyond the ESA, compliance with the Bald and Golden Eagle Protection Act (BGEPA) can create an added layer of complexity for alternative energy. Golden eagles and bald eagles are found throughout the United States. While typically thought of as a wind energy issue, the growing prevalence of eagle nests and accelerating alternative energy development on the landscape have created increasing interactions for solar and hydroelectric energy development as well. For example, the California Flats solar energy facility in California has obtained both an ESA permit for potential impacts to terrestrial species and a BGEPA permit for potential impacts to golden eagle nests in the vicinity of the project footprint. Given that project development can take several years, it is not uncommon to find eagle nests or increased eagle use within a project footprint where previously there had been none.

Project investors may require additional demonstration of BGEPA risk management where nests have been built within or near project boundaries.

Migratory birds

The Migratory Bird Treaty Act (MBTA), enacted in 1918, has received significant attention in the last decade due to highly publicised enforcement actions at wind energy facilities. MBTA is a strict liability statute that makes it a crime to hunt, take, or kill a migratory bird. Whether the MBTA actually applies to alternative energy projects (or any other commercial or industrial projects that may kill migratory birds incidentally while engaged in otherwise lawful activities) is currently in flux.

Beginning in the 1970s, USFWS applied the MBTA to the incidental take of migratory birds, but the Trump Administration has declared that the MBTA was never meant to extend to incidental take. That position, declared through a 2017 Department of Interior Solicitor’s opinion, is currently the subject of litigation. In 2020, the Trump Administration has proposed rules codifying its position.

Whether those rules will be finalised and whether they will withstand the inevitable legal challenges remains to be seen. Alternative Energy projects often have lifespans of many decades. The state of flux and potential exposure under the MBTA can impact alternative energy project financing.

Overall impacts

Technology is developing rapidly as a tool for project developers to assess and manage impacts to wildlife. Drones and cameras are increasingly employed to conduct surveys at solar and wind energy sites to measure activity and identify sensitive features such as raptor nests. For eagles, cameras are connected to wind turbine control systems and can signal specific turbines to shut down within minutes upon detection of an eagle.

Developments have been made in bat deterrent technology that allow wind energy developers to install devices on turbines that will discourage bats from flying near the turbines. Agencies are figuring out how to incorporate this emerging technology into impact estimates, minimisation efficacy and permit conditions within the limits of the relevant laws.


Offshore wind has been slow to take off in the United States, but has shown significant movement in the last several years, and the prospects for offshore wind generation in the USA are increasing rapidly.  The United States has only one operating offshore wind energy facility, the Block Island wind farm off the coast of Rhode Island. However, as of late 2019, active offshore leases for projects exceeding 21 GW have been issued from Maine down to North Carolina.

Several east coast states have held competitive bids for offshore wind projects to further state renewable goals. Many of these bids include revitalisation of the port cities that will serve as staging areas during project construction. For example, in late 2019 Connecticut awarded a project that included revitalisation of 18 acres in Bridgeport.

The Bureau of Ocean Energy Management (BOEM) is the regulatory agency that administers the Outer Continental Shelf (OCS) Renewable Energy Program in US federal waters (defined as the water at a distance of more than three miles from shore). BOEM regulations set forth an evaluation process for offshore wind in four stages: planning, leasing, site assessment and construction and operations. National Environmental Policy Act (NEPA) reviews occur at multiple stages of BOEM review.

BOEM guidance estimates that the first three stages alone (before reaching construction and operation) may take nearly ten years to complete. Vineyard Wind, off the coast of Massachusetts, has incurred significant delays due to NEPA review prior to beginning construction.

West coast development and gulf coast studies

Offshore wind development on the west coast is also drawing more interest. BOEM is in the planning stages for areas in offshore California and Hawaii. The California and BOEM “California Intergovernmental Renewable Energy Task Force” has initiated stakeholder outreach to identify appropriate areas in California for offshore wind development.

BOEM, the State Historic Preservation Officer of California and the Advisory Council on Historic Preservation entered into a programmatic agreement to address how BOEM will address its obligations under the National Historic Preservation Act when issuing approvals for offshore wind energy development in California. Hawaii similarly has co-ordinated with BOEM to establish a Hawaii Intergovernmental Renewable Energy Task Force to evaluate how to move forward with offshore wind development. While initial Texas offshore wind leases expired in 2014, signs also point to increased interest in the feasibility of offshore wind energy development on the Gulf Coast.

In April 2020, BOEM and the National Renewable Energy Laboratory announced two gulf coast studies analysing different offshore renewable energy technology and indicated the studies will inform federal, state and local renewable energy planning over the next decade.

Other legal interests

In addition to the BOEM regulatory regime and the associated NEPA and NHPA reviews, several other legal interests are relevant to offshore development. Native American tribes have raised concerns of interference with valuable marine cultural resources. Commercial fisherman have also raised concerns with respect to offshore wind impacts on their operations.

Impacts to marine species protected by the Marine Mammal Protection Act and the ESA must also be factored into project development. Multiple studies are also underway to understand offshore wind impacts to avian and bat species that may migrate off the coast. Finally, the underwater cabling and interconnection to the onshore power grid requires various federal and state legal considerations such as right-of-way use and interconnection processes.

Utility-Scale Battery Storage

Battery storage technologies have long been seen as a key to unlocking a fully renewable energy portfolio by allowing electricity suppliers to address the imbalance between energy demand and alternative energy production related to the intermittent nature of solar and wind resources. This area has grown tremendously in recent years, and 2019 was the United States energy storage industry’s biggest year of installations ever, with its largest single quarter in the fourth quarter last year.

In addition to a rapid increase in behind-the-meter battery storage installations, there appears to be a growing trend toward larger utility-scale battery storage projects. The appeal of these utility-scale systems is that they can reduce or even obviate the need for traditional gas-powered power plants to meet peak electrical demand needs. While few of the major utility-scale battery storage projects have been brought online so far in the United States, there are currently several being planned and constructed.

The largest projects anticipated to come online within the next few years are expected to exceed 100-megawatts, headlined by Florida Power & Light Company’s 409-megawatt Manatee Energy Storage Center announced last year, which will be powered by solar panels and replaces a pair of aging natural-gas-fired plants.

Pairing battery and alternative generation

The pairing of large battery systems with alternative generation (wind or solar) is increasingly popular. In 2016, there were 19 sites in the USA with paired battery and alternative generation systems; by 2019, that number had grown to 53 sites, and another 56 paired sites are projected to come on line by 2023. Most of the projected growth in battery storage is in Florida, Nevada, California, Arizona, Oklahoma and Texas.


Notwithstanding the announcement of megaprojects, the development of utility-scale battery storage projects has partially been limited by regulatory uncertainty that has inhibited investment. In response, the Federal Energy Regulatory Commission (FERC) issued Order 841 in 2018, which directed the regional transmission organisations (RTOs) and independent system operators (ISOs) that run the country’s wholesale electricity markets to craft new rules to allow storage resources to bid their services into the markets. The implementation of Order 841 continues to be contentious and is currently the subject of on-going litigation, with proponents arguing that it is a crucial tool to encourage battery storage development, and critics arguing that it encroaches on state authority over the distribution system.

Grid Resiliency

Recent major natural disasters have highlighted the role that alternative energy can play in building a more resilient power grid. As the United States anticipates more severe and damaging weather-related events in the future due to climate change, many have looked toward renewable technologies and battery storage to reduce the reliance on the traditional electrical grid and mitigate the impact of those disasters. Accordingly, significant efforts are underway both at the federal level and in several states to promote distributed energy resources and microgrids.

Following catastrophic wildfires in the western United States, there have been several legislative efforts to incentivise and facilitate the development of distributed energy resources and microgrids to make the power grid more resilient. Additionally, electrical utilities in California have implemented several public safety power shutoffs to preemptively de-energise large portions of their electrical distribution systems during weather conditions that present high wildfire risk, which can potentially go on for prolonged periods of time.

Both of these developments have placed a greater emphasis on energy storage and distributed energy resources to provide reliable backup power. For example, California’s Assembly Bill 1144 (Friedman, 2019) recently shifted the emphasis of the state’s utility-funded Self-Generation Incentive Program to grant significant financial incentives for renewable technologies and energy storage in wildfire-prone areas.

On the East Coast, hurricanes and other major storm events have also spurred several communities to invest in energy storage and distributed energy resources. In 2017, Hurricane Maria destroyed much of Puerto Rico’s power grid, leaving many without electricity for months. More recently, earthquakes in January 2020 again impacted the Puerto Rico Electric Power Authority’s critical infrastructure and resulted in significant power outages. These events have spurred many on the island to invest in standalone microgrids composed of solar and battery technologies intended to reduce reliance on the traditional power grid.


In the United States, alternative energy development is now outpacing traditional energy sources and has moved well beyond the peripheries of the energy sector into a primary focus of the energy industry nationally. The trends and developments highlighted here reflect an increasing interest in taking on larger and more ambitious alternative energy projects. The sector continues to work through federal and state regulatory barriers, but is maturing rapidly as a result of governmental incentives and market drivers. This growth trend is expected to continue over the course of the upcoming decade, even without federal tax incentives.
