California’s Diablo Canyon: A Looming Battle Over Ratepayer Funds and the Future of Nuclear Energy
California consumers could be on the hook for hundreds of millions of dollars annually to keep the state’s last nuclear plant, Diablo Canyon, operational – with little guarantee that money won’t ultimately benefit Pacific Gas & Electric’s shareholders. As state regulators prepare to finalize a controversial funding mechanism, a critical question looms: is this a necessary investment in energy security, or a potential windfall for a utility with a troubled past?
The debate centers around a “volumetric performance fee,” established by a 2022 law extending Diablo Canyon’s lifespan to 2030. This fee, averaging $13 per megawatt hour, is intended to compensate PG&E for keeping the plant running and covering potential liabilities. While the law explicitly prohibits shareholder profit, consumer advocates fear a lack of transparency will allow PG&E to strategically shift costs, effectively funneling ratepayer money into corporate coffers.
The Core of the Controversy: Transparency and Oversight
The California Public Utilities Commission (CPUC) is facing mounting pressure to provide rigorous oversight of how PG&E spends these funds. Currently, the utility is only required to report spending within broad “major work categories,” a system critics argue obscures the true financial impact on shareholders. “The commission is ready to throw in the towel,” warns Matthew Freedman, lawyer for The Utility Reform Network (TURN). “They’re going to let PG&E do what it wants.”
PG&E maintains that the CPUC lacks the authority to impose overly restrictive oversight and that the fee can be used to benefit customers by funding grid improvements and renewable energy projects. However, concerns remain that the utility could use the funds to cover expenses it would normally be responsible for, freeing up other revenue streams for shareholder returns. A state analysis even acknowledged the legislation lacked “guardrails” to prevent this very scenario.
Diablo Canyon’s Role in California’s Energy Mix
The extension of Diablo Canyon’s operations was spurred by concerns about grid reliability following 2021 blackouts and a recognition that renewable energy sources weren’t yet sufficient to meet California’s energy demands. Today, the plant provides approximately 8% of the state’s total energy and a significant 17% of its carbon-free energy. This makes it a crucial component of California’s ambitious climate goals, but also a point of contention as the state transitions towards a fully renewable future.

Beyond Diablo Canyon: The Wider Implications of the Fee Structure
The volumetric performance fee isn’t just impacting PG&E customers. Southern California Edison and San Diego Gas & Electric customers are also contributing to the fund, raising questions about equitable cost allocation. Advocates argue that the fees should first be used to offset Diablo Canyon’s operating losses – currently projected at $583 million annually – before being diverted to other projects. This would directly benefit all ratepayers, not just those within PG&E’s service territory.
The CPUC’s proposed decision includes some additional constraints, requiring PG&E to detail how many customers benefit from each project funded by the fee and to explain how these projects contribute to lower bills. However, a recent revision weakened the latter requirement, allowing PG&E to bypass this provision with a simple explanation. This compromise has further fueled concerns about a lack of accountability.
Potential for Strategic Cost Shifting
The current reporting structure allows PG&E to report spending in broad categories, masking the net effect on shareholders. Critics fear the utility could strategically use the fee to cover costs that would normally be borne by investors, effectively transferring the financial burden to ratepayers. Because a comprehensive rate case only occurs every four years, this potential for cost shifting could go undetected for extended periods.
Looking Ahead: The Future of Energy Funding in California
The Diablo Canyon funding debate highlights a broader challenge facing California: how to balance the need for reliable energy with the imperative of protecting ratepayers. The lack of transparency and oversight in this case sets a concerning precedent for future energy projects. The CPUC’s decision will not only determine the financial fate of Diablo Canyon but also shape the landscape of energy funding in the state for years to come.
The outcome will likely influence how California approaches funding for other critical infrastructure projects, particularly those involving private utilities. A failure to ensure accountability could erode public trust and hinder the state’s ability to achieve its ambitious climate goals. The situation underscores the need for robust regulatory frameworks and a commitment to transparency in the energy sector.
