Old 300 Solar Center is a utility-scale solar project in Fort Bend County, Texas. EIA's May 2026 inventory reports one 430 MWac operating photovoltaic generator, 539.61 MWdc, and an October 2024 registry operating date. Ørsted's current project page reports 430 MW of solar and a co-located 250 MWh, two-hour battery project; Ørsted separately lists the solar project in commercial operation since 2023. The different dates describe project-level and EIA registry milestones and should not be treated as the same event.
