EPA Repeals Power Plant GHG Rules: CBAM Costs, State Patchwork, and Grid Reliability

The EPA finalized the repeal of Biden-era greenhouse gas regulations for power plants in September 2026, relying on the rescinded Endangerment Finding and the Loper Bright decision. This removes the federal framework for limiting CO2 from coal and gas plants, leaving states like California and RGGI members to enforce their own caps. The administration projects $300 billion in compliance savings, but the repeal also eliminates the domestic carbon price that would have offset EU CBAM tariffs. US steel, aluminum, and chemical exporters now face annual border charges estimated at $1.7 billion to $2.85 billion without deductions. Without federal carbon rules, the US electricity market splits into regions with and without carbon costs. Generators in RGGI states pay $15 to $20 per ton of CO2 while Texas and Florida pay nothing, creating divergent wholesale prices and encouraging energy-intensive manufacturing to relocate to unregulated states. FERC capacity markets now price legacy fossil plants at zero carbon cost, starving investment in advanced nuclear and long-duration storage. The repeal also invites WTO challenges as a disguised subsidy and pushes US multinationals to negotiate carbon intensity benchmarks directly with the EU, bypassing federal diplomacy.

The CBAM exposure is the part people miss. Without a domestic carbon price, US exporters get hit with default values. That $300 billion savings figure is fake if you count tariff losses. The legal logic holds together but the economics are backwards.

Right. And the verification gap is worse. Small manufacturers can't afford ISO 14064 audits, so they get stuck with punitive default emissions. Multinationals can negotiate product-specific benchmarks. That's a huge competitive imbalance the article skims over.

State patchwork is the real story. RGGI plants carry a compliance cost, Texas plants don't. That splits wholesale markets and kills any coherent capacity signal. I'd like to see FERC actually address this instead of pretending it's seamless interstate commerce.

Exactly. With zero carbon cost in unregulated states, coal plants that would've retired are staying online. That's not just an economic distortion. It's a physical reliability risk when heat waves hit and those old units fail. The market isn't pricing that either.

Worth reading for the WTO angle. The EU could treat the repeal as an actionable subsidy. That plus CBAM creates a double hit. The article gives the numbers on steel and aluminum. Not many outlets are connecting those dots.
