NextEra Energy Nuclear Decommissioning Trust

The trust is a qualified nuclear decommissioning fund established under Internal Revenue Code Section 468A. It functions as a segregated, tax-advantaged vehicle funded by ratepayer contributions collected by Florida Power & Light. Assets inside the trust can only be used for qualified decommissioning expenses associated with FPL's St. Lucie and Turkey Point nuclear plants. The trust's investment income accumulates on a tax-deferred basis, with tax liabilities recognized only when funds are distributed for decommissioning activities.

The portfolio is liability-driven, holding a mix of public equities, investment-grade fixed-income securities, and cash equivalents. The allocation is calibrated to the approved decommissioning cost studies, with return assumptions designed to fully fund the dismantlement liability over the license term plus the allowable post-shutdown period. The trust does not invest in private equity, venture capital, or direct real assets — its mandate is shaped by regulatory cost-of-service principles and tax-qualified trust rules.

Contributions are calculated based on site-specific decommissioning cost estimates, trust fund performance, and projected escalation rates, all filed with and subject to approval by the Florida Public Service Commission. FPL collects the calculated amounts through electric rates charged to its Florida customers. If trust assets exceed the amount deemed necessary to fully fund the liability, the Commission can direct a reduction in collections or a refund to ratepayers.

The trust is a targeted liability-management vehicle, separate from NextEra's discretionary capital deployment. The broader $50–$55 billion figure (per the firm, 2024) represents new energy infrastructure projects undertaken by NextEra Energy and its subsidiaries. The decommissioning trust, in contrast, draws from ratepayer funds and exists solely to discharge a mandated environmental obligation.
