Spring Valley II Solar Final Environmental Impact Statement

The Tennessee Valley Authority (TVA) has decided to adopt the preferred alternative identified in its final environmental impact statement (Final EIS; Document ID EISX-455-00-000-1729685609) for the Spring Valley II Solar Project. The Final EIS was made available to the public on December 19, 2025. A Notice of Availability (NOA) of the Final EIS was published in the Federal Register on January 2, 2026 (91 FR 1). TVA's preferred alternative, analyzed in the Final EIS as the Proposed Action Alternative, consists of TVA executing a power purchase agreement (PPA) with Spring Valley Solar, LLC (Spring Valley Solar), a wholly owned subsidiary of Urban Grid, to purchase power generated by an approximately 200-megawatt (MW) alternating current (AC) solar photovoltaic (PV) facility, which would occupy approximately 740 acres of a 2,426-acre Project Site, in Colbert County, Alabama, south of the city limits of Tuscumbia, Alabama, near the City of Muscle Shoals and Florence, Alabama, along US Highway 43. To interconnect to TVA's existing electrical grid Spring Valley Solar, LLC, would build a new onsite 161-kV substation and install network upgrades to the nearby transmission lines (TL). This alternative would achieve the purpose and need of the Project to meet the energy needs in response to customer demands and aligns with TVA's 2019 Integrated Resource Plan (IRP).
