Rapid response: How the government shutdown will impact energy

October 1, 2025

On October 1, the federal government entered a shutdown after negotiations between Democrats and Republicans broke down. The parties could not agree on what to include in a continuing resolution (CR) to temporarily keep the government open while negotiating a full-year government funding agreement. The longest shutdown, in 2018–2019, lasted 35 days, and it is difficult to forecast how long this one may last.

In the near term, public equity and debt markets do not appear substantially shaken by the shutdown, which may change if the shutdown lingers or triggers other significant economic harm. Clean energy project developers and corporate tax credit buyers have questions regarding how the shutdown will impact their deals and projects. Crux anticipates that most Internal Revenue Service (IRS) functions should continue normally (at least for a shutdown of two weeks or less) and will be monitoring the issue closely.

Top questions heading into the shutdown

Will the IRS pre-filing registration portal continue operating during the shutdown? 

The corporate extended tax filing deadline is October 15 (for calendar-year tax filers). Companies seeking to utilize transferable tax credits to meet their 2024 tax liabilities will need to include a pre-filing registration number on their tax returns. While most companies with 2024 tax credits already have their pre-filing registration number, some are still waiting for the portal administered by the IRS to award these numbers. 

Our expectation from the IRS’ shutdown plan is that the agency will continue to be funded by appropriations from the Inflation Reduction Act of 2022 (IRA), and we anticipate that the portal will continue operating. We will closely monitor this issue — IRS operations could be further impacted if the shutdown extends beyond two weeks.

Will the IRS continue to issue regulatory guidance, including on issues related to Foreign Entity of Concern (FEOC)? 

The IRS was broadly expected to issue guidance to aid implementation of the FEOC rules in the coming weeks. While the agency’s shutdown plan indicates that it will continue to operate, guidance may be hung up while the government shutdown continues. It is possible staff that are furloughed and occupied by shutdown-related activities at other agencies — including the Office of Management and Budget (OMB), which reviews most guidance before publication — may delay the release of guidance.

Will agencies continue to process permit applications? 

Companies or projects with live permitting decisions before federal agencies such as the US Department of Energy (DOE) or the Department of the Interior may be delayed in receiving those decisions. In particular, projects that have been awarded the §48C advanced qualifying clean energy project awards may be delayed in receiving notice from the DOE as to their project milestones. Full permitting activity may not resume until the shutdown concludes. 

Shutdown basics and impact on energy

Until funding is restored, agencies operate under shutdown contingency plans. Programs can continue operating if they retain funding, either through multiyear or “no-year” appropriations, like some accounts within the DOE, or if they are funded outside the annual appropriations process (including mandatory spending such as Social Security or through reconciliation bills). 

During a shutdown, activities funded by annual appropriations pause unless designated “essential.” Essential functions are ones that maintain public safety, protect property, or have specific legal obligations. For example, law enforcement, the military, medical care, air traffic control, and power production and distribution are all deemed essential. Employees carrying out these functions continue to work without pay. Others are furloughed until funding resumes. Traditionally, the whole government reopens at once, but it is possible that Congress will open some agencies earlier than others.

The shutdown plans for the Department of the Treasury (Treasury), Interior, US Army Corps of Engineers (USACE), DOEEnvironmental Protection Agency (EPA), and the Federal Energy Regulatory Commission (FERC) are posted on their individual websites. However, it’s possible these become difficult to implement — baseline staffing levels at most agencies are significantly lower than at the beginning of the year, and it is unclear how proposed reductions in force (RIFs) will impact these plans. Additionally, as of October 1, the DOE’s posted plan has not been updated since December 2024, so there could be additional changes.

This makes it difficult to predict exactly how agencies will operate during this shutdown, though activities such as permitting, rulemaking, and grantmaking will likely see impacts and delays. The following summaries of what we currently expect are based on several departments’ operating plans for previous shutdowns:

  • Treasury: Dedicated funds provided by the IRA are expected to allow IRS work to proceed, including on tax credit guidance. However, impacted staff at other agencies may delay the release of guidance.
  • Interior: Some permitting activities are expected to continue. For example:
    • The Bureau of Land Management (BLM) is expected to continue permitting for oil, gas, transmission infrastructure, and related rights-of-way, as well as new leasing for energy and mineral resources necessary for energy production to address the national energy emergency declared under Executive Order 14156
    • The Bureau of Ocean Energy Management (BOEM) “will cease all renewable energy activities but continue limited work on conventional and marine minerals based on available resources.” 
  • USACE: Most activities are expected to continue due to funding outside the annual appropriations process. However, during past shutdowns, the Regulatory offices that oversee permitting closed, and USACE has not clarified whether it would suspend regulatory functions during this shutdown, too. 
  • DOE: Offices with “no-year” or “multiyear” appropriations may operate for several days or even weeks with minimal disruption, but impacts increase if the shutdown persists.
  • EPA: Emergency response, law enforcement, and litigation work are expected to continue. New grants, permits, and interagency agreements are halted. 
  • FERC: Most activities are expected to cease; only those focused on public safety and reliability of the grid continue.

Activities during the shutdown are subject to inherent uncertainties, and the longer a shutdown lasts, the greater the likelihood of services being impacted.  We will continue to monitor these situations as circumstances evolve.

Outlook

Past shutdowns have lasted as long as 35 days. Energy-related functions most at risk include permitting, rulemaking, and grantmaking across Treasury, Interior, USACE, DOE, EPA, and FERC. These functions could be further impacted by proposed RIFs during the shutdown.

We will continue to monitor:

  • Agency implementation of shutdown plans and RIFs.
  • Changes in agency operating status, particularly those that will continue relevant functions during the shutdown with non-annual appropriations funding (IRS, DOE, USACE).
  • Potential energy policy impacts from suspended or curtailed programs.
  • Negotiations to end the shutdown.

We will continue to keep our partners informed throughout the remainder of the shutdown, including through regular client memos. If you are interested in gaining access to these memos, get in touch to join the Crux platform.
