Southern California Public Power Authority Nuclear Decommissioning Trust

Southern California Public Power Authority Nuclear Decommissioning Trust

The trust was created as a financial mechanism to meet a future obligation. SCPPA, a joint powers authority formed in 1980, represents a group of California municipal utilities that own a combined interest in the Palo Verde Nuclear Generating Station in Tonopah, Arizona. The station is operated by Arizona Public Service Company. Federal and industry regulations require these utility co-owners to set aside dedicated funds that will one day pay for plant decommissioning, site restoration, and spent fuel management. The trust's corpus is built from charges included in the rates paid by millions of electricity customers served by SCPPA's members. Investment strategy is defined by safety, not returns. The trust portfolio is almost entirely allocated to low-risk, investment-grade fixed-income securities and cash equivalents that align precisely with the expected timing of decommissioning costs. The investment guidelines are shaped by Nuclear Regulatory Commission (NRC) rules and the trust agreement's approved spending schedule. The fund does not pursue direct infrastructure equity, co-investments, or venture stakes—its legal structure prohibits risk-taking that could leave ratepayers with a shortfall when decommissioning begins in earnest after the plant's operating license expires. SCPPA's broader energy activities, including a contract for solar and battery storage assets developed by Arevon Energy, are managed separately from the trust. Oversight resides with SCPPA's financial leadership. Executive Director Daniel E. Garcia and Chief Financial and Administrative Officer Aileen Ma are charged with ensuring the trust complies with all fiduciary and regulatory requirements. SCPPA's member utilities, which include some of the largest municipal power providers in the nation, collectively provide governance. The trust does not disclose total assets under management, but its funding is calculated through periodic actuarial studies that project decommissioning costs in 2020s dollars. In May 2026, SCPPA Board meetings continued to approve routine financial reports for the decommissioning fund (per the firm's official communications). The trust is structurally distinct because it is a single-purpose, liability-driven fund inside a public entity. It has no permanent staff dedicated solely to the trust, no investment committee with discretionary authority, and no external fundraising. Every decision filters through SCPPA's board of municipal utility representatives. The structure is a closed-loop system: ratepayer contributions accumulate, the portfolio earns modest interest, and the timeline stretches decades into the future until Palo Verde's three reactor units are permanently retired and dismantled.
