US EPA Poised to Repeal Power-Plant Carbon Rules, With Final Text Not Yet Public

Key Facts

1At verification time, EPA’s official page still described the repeal as a proposal rather than a completed final action.
2The primary option would repeal all power-sector greenhouse-gas standards, while the alternative would remove a narrower set of requirements.
3The cost-saving figures are the agency’s proposal-stage regulatory estimates and do not establish a move in energy prices or company shares.

The U.S. Environmental Protection Agency is poised to finalize a rule repealing federal greenhouse-gas standards for fossil-fuel power plants. At verification time, however, EPA’s website still described its June 11, 2025 action as a proposal, while the Associated Press reported that the final rule had not been made public. The repeal therefore should not be presented as completed.

EPA’s primary proposal would repeal all power-sector greenhouse-gas standards issued under Section 111 of the Clean Air Act. A narrower alternative would remove guidelines for existing steam-generating units and carbon-capture requirements for certain modified coal units and new baseload gas turbines.

The action is broader than a repeal of Biden-era rules alone. It reaches new-source standards first issued in 2015 as well as parts of the Carbon Pollution Standards issued on May 9, 2024 for existing coal plants, new gas turbines and certain oil- and gas-fired steam units.

Under the targeted 2024 standards, long-running coal plants and new baseload gas turbines were required to control 90% of their carbon emissions. Compliance dates for existing steam units range from 2030 to 2032, while the 90% capture standard for new baseload gas units is due on January 1, 2032.

When it proposed the repeal, EPA estimated regulatory-cost savings of as much as $19 billion over about 2 decades beginning in 2026, or roughly $1.2 billion annually. Those are the agency’s regulatory estimates, not evidence of a move in energy prices or company shares; the regulatory agenda also says the final rule’s costs and benefits remained under evaluation.

The economic effect will depend on the final text, the units covered and the effective and compliance dates. Legal challenges are expected, so investors should watch for official publication and subsequent litigation before assuming lower operating costs or a change in electricity prices.
