Pacific Gas and Electric Nuclear Decommissioning Trust

A board of independent trustees manages the trust's investment policy and oversees its external managers. DeWitt F. Bowman, the former Chief Investment Officer of the California Public Employees' Retirement System (CalPERS), has served as a trustee. Donald O'Connor, formerly of the Investment Company Institute, has also served as a trustee. They report to the California Public Utilities Commission.

The trust operates under a strict liability-driven mandate. Its primary obligation is to fully fund the dismantling of PG&E's retired nuclear plants, a multi-decade process with large terminal costs. This forces an allocation heavily weighted toward fixed income and inflation-hedging instruments, with an explicit goal of matching asset duration to liability cash flows rather than maximizing absolute returns. The target funded status is monitored by regulators.

All assets in the trust come from charges included in the electricity rates of PG&E's customers over the operating life of its nuclear plants. These funds are collected and transferred to the trust, where they are held in a legally separate structure from PG&E Corporation's general assets, solely for the purpose of future decommissioning activities.

No, the trust does not invest in companies that perform decommissioning services. Its mandate is strictly financial — to grow and preserve the pool of capital needed to pay for decommissioning contracts in the future. The actual dismantling work is procured separately by PG&E and its primary contractors.

The 2022 decision to extend Diablo Canyon's operations through 2030 pushed the trust's largest expected decommissioning cash outflows further into the future. This extension reduced the trust's near-term liquidity requirements and extended the investment horizon for a significant portion of its assets, potentially allowing for a marginally higher allocation to growth-oriented asset classes while still satisfying its liability matching requirements.

The trust's assets are legally separate from PG&E Corporation and were not available to creditors during PG&E's Chapter 11 proceedings concluded in 2020. The CPUC maintains specific regulatory provisions ensuring that decommissioning funds remain segregated and can only be used for their intended purpose, providing a layer of protection distinct from the parent utility's corporate structure.

Nuclear decommissioning costs are highly sensitive to wage and materials inflation over decades. The trust addresses this mismatch by allocating a portion of the portfolio to commodity-linked derivatives and inflation-protected securities. These holdings are explicitly designed to preserve real purchasing power against the specific cost escalators that drive decommissioning expense estimates.
