California carbon market overhaul puts compliance costs in doubt for power producers
CARB's free-allowance plan offers industry relief but risks undermining the state's 2030 emissions target.
The California Air Resources Board voted on Friday (2026-05-29) to approve major changes to the state's cap-and-invest program, including a mechanism that could provide polluting industries with up to $4 billion in free compliance credits.3 The MDI, as CARB calls it, is designed partly to address backlash over fuel costs that became a political liability for Governor Gavin Newsom.2 Environmental groups and state lawmakers argue the plan threatens the program's ability to meet California's near-term target of reducing carbon emissions by 40% from 1990 levels by 2030.3
For power traders, that debate is concrete. California's carbon price directly affects the dispatch economics of gas-fired generation relative to renewables and imports. If the MDI depresses allowance clearing prices, gas plants holding compliance positions face a mark-to-market loss on their hedges. The April revised plan also set aside roughly $800 million in additional compliance support for polluting industries beyond the credit mechanism.3,2
CARB officials noted that the federal approach to industrial decarbonization funds has shifted sharply under the Trump administration, and argued the MDI could help offset the billions stripped from federal programs.3 But the free credits come at a structural cost: fewer allowances circulate through the auction market, reducing the direct financial incentive for emitters to cut output. Environmental opponents are not wrong to flag that tension.
Newsom is simultaneously managing a separate fiscal track. On Wednesday (2026-05-20), the governor said he had held "very positive and constructive conversations" with the Trump administration to secure a reduced federal request for wildfire recovery funding around Los Angeles.1 The dual pressure — easing carbon costs for industry while seeking federal disaster money — reflects how wildfire liabilities are reshaping Sacramento's budget priorities.
PG&E's situation illustrates the scale of those liabilities. The California Public Utilities Commission is receiving public comments on a proposed settlement that would penalize the utility $22 million for the 2022 Mosquito Fire, which burned more than 75,000 acres in Placer County.7 "The financial impact of past wildfires is significant," PG&E said in its last quarterly filing.7 That burden feeds into state-level debates over whether ratepayers, shareholders, or general taxpayers ultimately absorb the cost.
California's energy conflict with Washington extends beyond carbon policy. The state plans to sue the U.S. Department of the Interior over agreements to pay Invenergy $765 million to terminate four offshore wind leases, including the Golden State Wind project off the Morro Bay coast.4 Offshore wind was expected to contribute to the state's goal of 25 GW of offshore capacity, a target that now looks increasingly difficult given federal opposition and project economics.4,6
Federal drilling policy is moving in the opposite direction. On Thursday (2026-07-02), the Bureau of Land Management opened a 30-day comment period for new oil and gas leasing plans in California, even as state officials resist new development.5 More than 95% of federal drilling in California occurs in Kern County, generating more than $200 million annually in economic activity and between $65 million and $90 million in federal royalties each year.5
Between 2019 and 2026, California added 30.8 GW of clean energy and battery storage.6 The grid still depends on gas-fired generation for evening peaks and multi-day renewable droughts. The MDI, by softening the effective carbon cost for industrial emitters, will likely extend the economic life of some gas plants beyond what a tighter allowance market would allow.
The next quarterly CARB allowance auction will be the clearest test. If MDI-driven free credits depress clearing prices significantly, the signal reaches traders fast. If prices hold, the more pressing question is whether the free allowances are deferring compliance costs rather than eliminating them — for a state that still targets net zero by 2045 and is simultaneously fighting Washington on offshore wind, federal leasing, and wildfire recovery money.3,4
