Federal Power Act: The Department of Energy’s Emergency Authority

Federal Power Act: The Department of Energy's Emergency Authority

Updated January 20, 2026 (R48568)

Section 202(c) of the Federal Power Act (16 U.S.C. §824a(c)) grants the Secretary of Energy certain authorities over the temporary operation of the electricity system during emergencies. Actions by the Trump Administration have highlighted this authority and raised questions about its future implementation. This report provides a brief history of the emergency authorities and discusses current issues and considerations for Congress.

History of Section 202(c)

The Federal Power Act was enacted in 1935 and included emergency authority language. At the time, federal oversight of the electricity system was conducted by the Federal Power Commission (FPC). Now, the Federal Energy Regulatory Commission (FERC) has most responsibilities for electricity system oversight—but not for emergencies. The emergency authority was transferred to the Secretary of Energy when the Department of Energy (DOE) was established by the Department of Energy Organization Act (P.L. 95-91) in 1977. Hereinafter, the emergency authority is described as residing with DOE.

Section 202(c) of the Federal Power Act provides DOE broad discretion to require almost any change to the operation of the U.S. electricity system on a temporary basis. Specifically, DOE may "require by order such temporary connections of facilities and such generation, delivery, interchange, or transmission of electric energy as in its judgment will best meet the emergency and serve the public interest."

DOE may execute this authority during war or at any other time it "determines that an emergency exists by reason of a sudden increase in the demand for electric energy, or a shortage of electric energy or of facilities for the generation or transmission of electric energy, or of fuel or water for generating facilities, or other causes." This report focuses on the authority as used during emergencies, not war, and it focuses on DOE's authority—it does not discuss other energy emergency authorities.1

In 2015, Congress amended Section 202(c) to specify how the emergency authority should interact with environmental requirements for power plants. In practice, the amendments prioritize electric reliability over environmental outcomes, essentially by providing a waiver of federal, state, or local environmental laws and regulations during times of emergencies.

This waiver has limitations. First, DOE emergency orders that may result in conflicts with environmental requirements may be issued for 90-day periods. They may be renewed for additional 90-day periods as long as DOE deems these renewals necessary to meet the emergency.

Second, if an emergency order would result in a violation of a federal, state, or local environmental law or regulation, DOE must ensure the order is in effect "only during hours necessary to meet the emergency and serve the public interest." Lastly, DOE must "to the maximum extent practicable" ensure the order is consistent with environmental laws or regulations and "minimizes any adverse environmental impacts."

DOE Implementation

DOE's regulations for implementing its emergency authority were finalized in 1981.2 The regulations define terms, including "emergency," and specify requirements for requesting an emergency order.

The Section 202(c) emergency authority is focused primarily on short-term situations—though, as shown below, DOE has exercised this authority in situations of varying duration. DOE's regulations emphasize the short-term nature of "emergencies" in this context. In the 1981 rulemaking, DOE explained,

The DOE does not intend these regulations to replace prudent utility planning and system expansion. This intent has been reinforced in the final rule by expanding the 'Definition of Emergency' to indicate that, while a utility may rely upon these regulations for assistance during a period of unexpected inadequate supply of electricity, it must solve long-term problems itself.3

DOE and FPC have used the emergency authority several dozen times since 1935 in response to different kinds of emergencies.

DOE's website contains information on use of the emergency authority since 2000.4 From 2000 through 2025, DOE used its emergency authority in response to 25 events (Table 1). Eleven events were weather-related and included hurricanes, heat waves, and winter storms. Some events prompted multiple emergency orders, either because more than one utility experienced emergency conditions (e.g., Winter Storm Elliot in 2022) or because the initial emergency order was extended (e.g., the California energy crisis of 2000-2001).

Details on the use of the Section 202(c) emergency authority prior to 2000 are not available in a single DOE repository; they are therefore more difficult to comprehensively compile. According to one compilation, the emergency authority was used 29 times prior to 2000; 22 of these occasions were in association with World War II.5

The duration of emergency orders under Section 202(c) has varied; some have lasted a few hours, while others have been extended to cover events lasting more than a year. Among the orders listed on DOE's website, the shortest order CRS identified occurred in response to a heat wave in Texas in September 2023. DOE granted an emergency order in this case for four hours on each of two days to respond to the highest levels of expected electricity demand.6 The order allowed one coal-fired unit and 16 natural gas-fired units to operate in violation of limits on sulfur dioxide, nitrogen oxide, mercury, carbon monoxide, and wastewater during those hours, if required to maintain electric reliability.

In the longest event CRS identified among the orders listed on DOE's website, DOE granted multiple renewals to a request to allow two coal-fired units in Virginia to continue operating, as needed for reliability, in violation of mercury emissions limitations while a transmission facility was constructed. Emergency orders in response to that event were in effect from June 16, 2017, to March 8, 2019.7

Puerto Rico is listed as a state for purposes of this table. Events listed as being extended had additional, subsequent emergency orders issued after the expiration of the initial emergency order(s).

Trump Administration Actions

On April 8, 2025, President Trump issued Executive Order (E.O.) 14262, "Strengthening the Reliability and Security of the United States Electric Grid."8 E.O. 14262 directs DOE to "streamline, systemize, and expedite" its processes for issuing emergency orders when "the relevant grid operator forecasts a temporary interruption of electricity supply is necessary to prevent a complete grid failure." A blackout is an example of a temporary interruption of electricity supply.

The E.O. additionally directs DOE to develop "a uniform methodology for analyzing current and anticipated" electricity supply and demand balance and a "protocol to identify which generation resources within a region are critical to system reliability." The protocol must "include all mechanisms available under applicable law, including Section 202(c) of the Federal Power Act, to ensure any generation resource identified as critical within an at-risk region is appropriately retained." Further, the protocol must prevent, "as the Secretary of Energy deems appropriate and consistent with applicable law," identified resources from "leaving the bulk-power system" or converting fuels in such a way that reduces their accredited capacity. An example of fuel conversion that could reduce accredited capacity is replacing a coal-fired power plant with a solar farm.

In July 2025, DOE released a report in response to E.O. 14262.9 The report estimated supply and demand balance (resource adequacy) for the United States in 2030 using a methodology capable of evaluating hourly demand and supply balances. DOE projected that by 2030 total electricity demand would grow by 101 gigawatts (GW): a 50 GW increase from data centers and a 51 GW increase from other sources. DOE's report used two scenarios of future electricity supply, reflecting different assumptions about power plant retirements.10 DOE used historic weather data to account for hourly changes in both supply and demand. In the low-supply case, the estimated annual loss of load hours (a measure of resource adequacy) increased from 8.1 hours for the current system to 817 hours in 2030.11 In the high-supply case, the estimated loss of load hours increased to 269.9 hours in 2030.12 The report pointed out that the estimated loss load

is not an indication that reliability coordinators would allow this level of load growth to jeopardize the reliability of the system. Rather, it represents the unrealizable AI and data center load growth under the given assumptions for generator build outs by 2030, generator retirements by 2030, reserve requirements, and potential load growth. These numbers are used as indicators to determine where it may be beneficial to encourage increased generation and transmission capacity to meet an expected need.

The language of the E.O. is nonspecific regarding the duration of any DOE action to retain resources or prevent them from leaving the bulk-power system. The E.O. language could be interpreted to mean DOE should take long-term action (i.e., lasting multiple years) or indefinite action. Emergency orders issued in response to multiyear events would be unusual, though not unprecedented, applications of DOE's Section 202(c) authority. It is unclear the extent to which limits to the authority might exist through judicial review or other avenues if DOE were to choose to issue long-term or indefinite emergency orders.

DOE issued emergency orders for three separate events in May 2025; the orders all involved seemingly new interpretations of the emergency authority. DOE extended each of the three events in August 2025 and again in November 2025.

One event was anticipated electricity supply shortages in Puerto Rico in summer 2025.13 One of two DOE emergency orders pertaining to Puerto Rico directed the local utility to conduct vegetation management (e.g., shrub clearing) around specified transmission lines on the island.14 CRS has not identified any other emergency orders issued from 2000 to the present addressing vegetation management.

The other two events involved elevated risk of supply shortages in parts of the Midwest and Eastern United States. DOE ordered a delay in retirement plans for a coal-fired power plant in Michigan and a natural gas/oil dual-fired power plant in Pennsylvania.15 Unlike in the cases of other emergency orders issued since 2000, the relevant grid operators in these cases appear to have not requested DOE action. Moreover, neither grid operator had identified reliability risks specifically associated with the retirement of the power plants in question at the time the operators approved those retirements. One of the affected grid operators, PJM, issued a supportive statement following the emergency order.16

Later in 2025, DOE issued additional emergency orders to delay retirements of four coal-fired power plants: one in Washington state, two in Indiana, and one in Colorado.17 In these cases, as in the cases of the Michigan and Pennsylvania power plants, the relevant grid operators do not appear to have requested DOE action.

For the delayed retirements in Michigan and Pennsylvania, the costs of maintaining the power plants are to be shared among electricity consumers in the affected regions, not just the states in which the plants are located.18 As of the date of this report, it is unclear how costs for maintaining the other four affected power plants (in Washington, Indiana, and Colorado) will be recovered.

Other DOE emergency orders issued in 2025 were more typical of orders in previous Administrations since 2000, in that they were issued in response to a grid operator request. In June 2025, DOE issued an emergency order in response to a request from a utility anticipating high electricity demand during a heat wave.19 The duration of the June 2025 emergency order was less than two days. In July 2025, DOE issued an emergency order in response to PJM's request to allow an oil-fired power plant in Maryland to operate if needed for reliability, potentially in excess of operational limits due to sulfur dioxide restrictions. It does not appear that those reliability conditions were met. DOE extended that emergency order in October 2025.20

Issues for Congress

E.O. 14262 does not specify how the Secretary of Energy should streamline its processes for issuing emergency orders. Congress could evaluate whether DOE's existing regulations would benefit from streamlining and, if Congress determines they do, could provide policy direction and set a timeline for updating the regulations. Congress could also defer to DOE's discretion as to when and how to update its regulations.

Regarding the statutory authority itself, Congress could consider whether amendments to Section 202(c) of the Federal Power Act are appropriate. The primary language has remained unchanged since 1935, potentially reflecting Congress's continued view over this time period that the original authorization is appropriate. Nonetheless, the U.S. electricity system has changed in many ways since 1935, and Congress might choose to consider reevaluating the authority.

One potential aspect for congressional consideration is the duration of DOE emergency orders, especially in relation to critical resources identified pursuant to E.O. 14262. Under current law, and assuming such orders might result in a conflict with environmental requirements, DOE could potentially reissue its emergency orders every 90 days for an indeterminate amount of time. Repeated emergency orders may raise feasibility questions, such as whether successive emergency orders would be upheld by the courts or whether power plant owners would make long-term investments to maintain power plants that are operating primarily under emergency orders.

Congress could consider evaluating and clarifying via legislation whether the Section 202(c) authority is better reserved for short-term situations or whether application to long-term situations is appropriate. Some backers of power plants at risk of retirement (e.g., coal-fired power plants) might support extended emergency orders based on long-term economic considerations. At the same time, some backers of power plants with low greenhouse-gas emissions (e.g., solar generators) might support extended emergency orders based on long-term environmental considerations. Others might prefer to limit DOE's emergency authorities to short-term situations. A more limited role for DOE in electricity system operations allows for greater use of market forces and reliance on local- and state-level processes to prepare for and respond to emergencies.

Another potential aspect for congressional consideration is the definition of "emergency" in the context of Section 202(c). Current law gives DOE broad discretion in determining what constitutes an emergency. Congress could consider whether this level of discretion is appropriate, or whether additional (or alternative) statutory direction would better serve current system needs.

As noted above, some supporters of specific kinds of power plants might view sustained economic conditions or environmental impacts as emergencies that warrant DOE action. Those situations would appear to be novel exercises of DOE authority under Section 202(c), if DOE were to interpret them in such a way. Amendments to the Federal Power Act could clarify congressional intent regarding use of DOE's emergency authority in response to those situations or any other long-term situation.

Other stakeholders might wish to limit DOE's discretion in when to issue emergency orders—for example, by modifying the currently broad statutory language or by requiring additional review by FERC or another entity.

A third potential aspect for congressional consideration is the scope of interventions allowed under the emergency authority. Current law allows DOE to order almost any change in operation of the electricity system.

Emergency orders between 2000 and 2024 directed either the operation of certain generators as needed for reliability or the temporary interconnection of the main Texas grid with neighboring regions' grids. One of DOE's May 2025 emergency orders requires Puerto Rico's local utility to conduct vegetation management activities.

One operational consideration that has not been tested under DOE's emergency authority (at least not in the orders available on DOE's website) is the curtailment of certain generators. Curtailment occurs when a grid operator directs a generator to reduce its output or cease operating altogether for a certain amount of time. Curtailment is sometimes necessary when generation levels in a given location exceed the transmission system's capacity to transmit energy out of that location.

Congress could evaluate the appropriateness of DOE's currently broad discretion to order interventions in the operation of the electricity system. Amendments to the Federal Power Act could clarify what kinds of interventions DOE would be authorized to require.

In both supply scenarios, 209 gigawatts (GW) of new supply are added by 2030, based on utility reports of new power plants in advanced stages of development as of 2024. In one case, DOE assumes that 104 GW of supply are retired, based on announcements as of 2024, for a net new supply of 105 GW. In the other case, DOE assumes no retirements.

Documents related to this emergency order are available on DOE's website at https://www.energy.gov/ceser/federal-power-act-section-202c-pjm-interconnection-0. In its July 2025 application for the emergency order, PJM estimated the affected power plant had "only 80 hours of run time remaining" for the year. In its October 2025 application for the extension of the emergency order, PJM estimated the affected power plant had "approximately 80 fuel oil burning hours remaining," suggesting that the affected power plant did not operate between July and October.
