The Tennessee Valley Authority (TVA) and Colbert County Commission docketed site development approvals for the 200 MW Spring Valley 2 Solar project. Features 200 MW of single-axis tracking photovoltaic modules covering roughly 1,500 acres of flat agricultural terrain. Represents an estimated 230 million USD private clean generation investment in the Muscle Shoals region. Interconnects to TVA's Spring Valley 161 kV substation corridor in southeastern Colbert County. Generates over 420,000 MWh of zero-carbon energy annually, offsetting regional peak power costs. Timeline: planned project targeting commercial operation in December 2028 (estimated) under regional grid interconnection queue and state regulatory schedules.ROD names Spring Valley Solar, LLC, then an Urban Grid subsidiary, and a 161 kV substation. EIA still lists approvals pending; the operator’s summer-2026 construction target is not verified actual commencement. Current branding is Panthera Grid Partners. No $230M budget is established. Timeline: Confirmed April 8, 2026 publication of TVA’s record of decision, not a commissioning date. EIA February 2028 and operator early-2028 targets remain estimates. Operator regional location diagram for Spring Valley II; not a project boundary or construction photograph. Operator 178 MW and ROD/EIA 200 MW scopes remain unresolved.
