EPA promises cheaper power; health groups see a wider rollback
The Environmental Protection Agency finalized the repeal of most greenhouse-gas requirements imposed on U.S. power plants under the Biden administration on September 14, while proposing to remove the remaining federal climate standards for the sector. EPA Administrator Lee Zeldin announced the actions at the G20 Energy Abundance Ministerial in Houston, framing them as a response to rising electricity demand and a way to keep coal and natural-gas plants operating.
The agency estimates that the final repeal will save the power sector and American consumers up to $310 billion. A separate proposal to eliminate all remaining greenhouse-gas standards for fossil-fuel power plants would save another $370 million in direct compliance costs over 20 years if adopted.
Environmental groups reject that accounting. They say the rollback removes safeguards from one of the largest sources of U.S. climate pollution and will expose communities to more harmful emissions. The final rule is expected to face legal challenges after publication in the Federal Register.
Lee Zeldin ties the repeal to reliability and coal
EPA’s final action strikes most of the 2024 Carbon Pollution Standards, including requirements covering existing coal-, oil- and gas-fired steam units and carbon-capture standards for certain coal and natural-gas plants. The agency says the requirements relied on control technologies that were not demonstrated at the scale and speed needed, and that the rules could force premature plant retirements.
“For over 15 years, the Obama and Biden administrations implemented a war on coal to destroy reliable and affordable energy,” Zeldin said in the EPA announcement. “The Trump Administration has come in to protect American energy and to make sure you can afford to keep the lights on.”
The agency also projects that coal production for power-sector use will increase by more than tenfold. EPA argues that the repealed standards improperly pushed utilities toward particular fuels and technologies rather than allowing them to decide how to meet demand.
The accompanying proposal goes further. EPA says Section 111 of the Clean Air Act does not authorize the agency to regulate power-plant greenhouse gases in response to global climate change concerns. The proposal relies partly on the administration’s February 2026 rescission of the 2009 Endangerment Finding and on the Supreme Court’s 2024 decision in Loper Bright Enterprises v. Raimondo.
AI data centers sharpen the electricity debate
The repeal arrives as technology companies and data-center developers compete for access to electricity for artificial-intelligence systems. Federal regulators recently directed six regional grid operators to help AI data centers and other large users connect to the transmission system more quickly, reflecting concerns that new computing facilities are arriving faster than power infrastructure can expand.
The Federal Energy Regulatory Commission said the order should allow large users to connect in a timely and orderly manner while requiring data centers to pay the full cost of grid upgrades tied to their connections. The action covers regional operators serving about 200 million Americans, or roughly two-thirds of FERC’s jurisdiction.
Developers are turning increasingly to natural gas and other dispatchable sources as they search for dependable power. That demand gives the administration a direct political argument for keeping existing fossil-fuel plants online, but it also raises questions about who will absorb the health and environmental costs of additional generation.
Recent federal moves have also sought to make data-center construction and on-site generation easier to permit. Critics say those policies, combined with the power-plant rollback, could reduce scrutiny as communities confront higher electricity demand, air pollution and pressure on water supplies.
Opponents point to pollution and litigation
Vickie Patton, general counsel for the Environmental Defense Fund, said the repeal would impose costs that EPA’s savings estimate does not capture. “Tearing down our national protections against climate pollution from power plants will have enormous costs for the health, safety and well-being of families across the country,” Patton said, according to The Associated Press.
Coal, gas and oil-fired power plants account for about one-quarter of U.S. climate pollution, second only to transportation, AP reported. Environmental and public-health groups say dismantling the rules could also increase emissions of smog-forming pollutants, mercury, lead and fine particles that damage the lungs.
The administration says the 2024 rule exceeded EPA’s authority and required technologies that plants could not deploy at a realistic pace. Opponents are expected to argue that EPA is abandoning its duty to address pollution that threatens public health and welfare.
The final rule is only the first legal step
The repeal takes effect after publication in the Federal Register, while the broader proposal must go through public comment before EPA can finalize it. That creates two separate legal fights: one over the immediate removal of the 2024 requirements and another over whether the agency can permanently deny itself authority to regulate greenhouse gases from power plants.
EPA’s action therefore does more than alter compliance deadlines for coal and gas facilities. It attempts to reset the legal basis for federal power-sector climate regulation at the same moment that AI developers are seeking enormous new supplies of electricity.
For utilities, the immediate question is whether plants facing retirement or expensive emissions controls will remain available to serve new demand. For the courts, the dispute will center on whether EPA’s reading of the Clean Air Act can survive challenges from states, environmental organizations and other parties.
