Santee Cooper Nuclear Decommissioning Trust

The trust has a pure defeasance mandate. IRS rules for qualified nuclear decommissioning trusts require funds be invested conservatively to match the cost of dismantling a reactor at end-of-life. The trust's portfolio is concentrated in zero-coupon U.S. Treasury securities and government-agency zeros, structured to mature exactly when decommissioning liabilities come due, not to generate alpha.

The trust is governed by its board, chaired by Peter McCoy, and operates under Santee Cooper's executive leadership, including President and CEO Jimmy Staton. Day-to-day investment management is likely outsourced or directed under strict statutory investment guidelines for nuclear decommissioning trusts, which cap equity exposure and mandate a heavy fixed-income focus.

No evidence suggests the trust participates in fund commitments, co-investments, private equity, or direct infrastructure equity. Its known holdings are limited to U.S. Treasury strips and government-agency zero-coupon bonds, which fits the standard IRS safe harbor for decommissioning trust portfolios.

The May 2025 restart agreement for V.C. Summer Units 2 and 3 is a major event for Santee Cooper and Brookfield, but the trust's obligation is specifically tied to Unit 1's eventual decommissioning. Units 2 and 3 were never completed and are not part of this trust's liability stream. The restart may complicate the site's overall nuclear footprint, but the trust's funding path for Unit 1 remains separate.

Funding comes from South Carolina ratepayers through the state-owned utility Santee Cooper, which is required by federal and state law to set aside money for decommissioning its nuclear facility. The trust is the designated external vehicle for those accumulated contributions, keeping the funds segregated from the utility's operating budget.

Neither. It is a qualified nuclear decommissioning trust under Internal Revenue Code Section 468A, a highly regulated funding vehicle specific to nuclear power plant operators. It has no external limited partners, no performance fees, and no profit motive — it is a cost-recovery mechanism for a known future industrial liability.

The utility and ultimately its ratepayers bear the residual risk. Santee Cooper, as the licensee, must ensure decommissioning is fully funded; any shortfall in the trust would require the utility to make additional contributions from operating revenue or rate adjustments, subject to South Carolina Public Service Commission oversight.
