Frequently asked questions

What is the source of the trust's assets?

The trust is funded by contributions collected from San Diego Gas & Electric customers through their utility rates. These funds are designated exclusively for the future decommissioning of SDG&E's 20% share of the San Onofre Nuclear Generating Station.

Who oversees the trust's investment and withdrawal activity?

The California Public Utilities Commission holds regulatory authority over the trust. SDG&E must obtain CPUC approval for withdrawals and for any material changes to the investment strategy, ensuring the assets are managed prudently and solely for decommissioning purposes.

Which assets are held within the trust?

Known allocations include a municipal bond portfolio and commodity exposures. The trust operates under IRS Section 468A qualification, which restricts investments to a conservative mix of public securities, fixed-income instruments, and certain permissible commodities.

Does the trust make direct venture capital or private equity investments?

No. The trust is a liability-driven pool that does not pursue venture capital, private equity, or direct company investments. Its mandate is structured around capital preservation and scheduled withdrawals for nuclear decommissioning milestones.

How much capital does the trust currently manage?

The trust has not publicly disclosed its current assets under management. SDG&E reports trust-related balances in aggregate regulatory filings, but no recent standalone AUM figure is available.
