Old 300 Solar Center
ØrstedFort Bend CountyERCOT
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.

Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at BCK_RN over 365 days (2025-10-26 to 2026-10-25).
The TB2 figure is a price benchmark, not revenue: it values one perfect-foresight cycle per day between the 2 cheapest and 2 dearest hours of each day, gross of round-trip losses, and excludes ancillary services and any physical dispatch constraint. It describes what this node’s price shape was worth over the window — it is not this asset’s realized capture, and no dispatch is assumed or modelled.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
EIA reports October 2024 for the 430 MW operating generator record.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
