Tennessee Valley Authority Nuclear Decommissioning Trust

The trust is a dedicated funding vehicle that accumulates and invests capital to pay for the future decommissioning of TVA's three nuclear power plants — Browns Ferry, Sequoyah, and Watts Bar. These costs include reactor dismantlement, spent fuel management, and site restoration. The trust is funded through ratepayer charges and federal contributions, and its investment returns directly offset what would otherwise be higher electricity rates or taxpayer burdens when decommissioning begins.

The trust's entire portfolio exists to match a known, long-dated liability curve tied to reactor license expirations extending to the 2050s. This forces an investment framework that prioritizes cash-flow predictability and inflation protection over absolute return maximization. Asset classes like real estate, REITs, and natural resource equities are selected because their income streams and appreciation patterns correlate with the construction-cost inflation that drives decommissioning expenses.

Ultimate fiduciary authority rests with the TVA Board of Directors, a presidentially appointed and Senate-confirmed body currently chaired by Bill Renick. The CEO and President of TVA, Don Moul, oversees executive management. Day-to-day investment operations are executed by TVA treasury and investment staff, supported by external investment consultants and managers selected through federal procurement processes.

The TVA Nuclear Decommissioning Trust and the Tennessee Valley Authority Retirement System are legally distinct pools with entirely different beneficiaries. The decommissioning trust serves ratepayers and the public interest by funding reactor cleanup; the retirement system serves TVA employees and retirees. Their asset allocations, governance committees, and investment policies are managed independently, though the TVA Board provides overarching governance to both.

The trust does not invest in operating nuclear plants or energy generation assets. Its mandate is to build a portfolio of diversified, income-generating assets — real estate, REITs, and natural resource equities — whose returns will be drawn down decades from now to pay decommissioning contractors. The trust's connection to nuclear energy is solely through the liability it exists to defease, not through thematic energy-sector investment.
