EPA Moves to Erase Power Plant Carbon Limits While Its Own Analysis Projects Higher Near-Term Prices
The Environmental Protection Agency said it would erase any limits on emissions from coal and gas power plants. The statement, reported on Sept. 16, covers a sector responsible for a quarter of all U.S. greenhouse gas emissions. The Guardian
Administrator Lee Zeldin signed the final Partial Repeal of the Carbon Pollution Standards for fossil fuel-fired electric generating units on Sept. 14, 2026. The action finalized the repeal of the majority of provisions of the 2024 Carbon Pollution Standards for greenhouse gas emissions from fossil fuel-fired electric generating units. At the same time, the agency proposed repealing all remaining greenhouse gas standards for fossil fuel-fired power plants. It said it will hold a virtual public hearing on the proposed Repeal of the Greenhouse Gas Emissions Standards for Fossil Fuel-Fired Electric Generating Units.
The sequence was telegraphed. On Sept. 13, 2026, Reuters reported, citing Bloomberg News, that the U.S. EPA was poised to repeal carbon standards for gas and coal power plants. Reuters The agency headlined its Sept. 2026 power-plant action as delivering $300+ billion in savings. EPA It later specified reversing the 2024 Biden-era carbon pollution standards will save $310 billion and save billions of dollars in compliance costs for the power sector. The agency said revoking the Biden-era power plant greenhouse gas rule would help "unleash" American energy. Associated Press
Zeldin vowed that Americans will see a decrease in electricity prices when justifying the rollback. The Regulatory Impact Analysis published with the new rule projects a different near-term path. It projects retail electricity prices will be 0.7% higher in 2030 as a result of the rule change. It states power prices will not drop until the mid-2030s and beyond. It finds coal delivered for power will be 27.3% more expensive than otherwise by 2045.
The cost ledgers conflict. EPA previously found the 2024 pollution standards would provide up to $370 billion in net climate and public health benefits over two decades. An NRDC analysis found people in the U.S. will spend an extra $30 billion a year on electricity by 2035 due to Trump's policies. The Guardian
EPA stated that models continue to show greenhouse gas emissions from power plants have no material impact on global climate change. EPA
The broader context here is the distinction between a partial repeal already signed and a full repeal only proposed. Practitioners will read the Sept. 14 final action as removing most 2024 requirements for fossil units while leaving the residual standards in place pending notice, comment and the virtual hearing. That two-track structure creates parallel compliance and litigation timelines. Utilities must decide capital and retirement planning under an interim regime that the agency intends to eliminate entirely.
Looking at what this means for price and fuel economics, the tension is internal to EPA documents. The public justification centers on lower retail prices and avoided compliance outlays. The agency's own analysis prices retail power higher in 2030, delays any decline to the mid-2030s and beyond, and prices delivered coal higher by 27.3% by 2045 relative to the baseline. The numbers do not align. For expert readers, the question is whether avoided capital expenditure on controls and new gas build is being offset in the modeling by shifts in dispatch, fuel mix and load.
In my view, the savings claims require the same careful parsing. The $310 billion figure counts avoided compliance costs from reversing the 2024 standards. The foregone benefits ledger from the prior EPA finding puts up to $370 billion in net climate and public health benefits over two decades on the other side. The NRDC estimate of an extra $30 billion per year on electricity by 2035 adds a consumer-expenditure dimension. None of these estimates measure the same thing. Compliance savings accrue to owners and operators. Health and climate benefits accrue diffusely. Retail expenditure reflects rates, demand growth and resource adequacy. Conflating them obscures tradeoffs that regulators, system planners and courts will need to disaggregate.
