South Plains II
Onward EnergyFloyd County
South Plains II is a 300 MW wind facility in Floyd County, Texas. EIA's May 2026 inventory reports one operating generator dated June 2016 and lists Onward Energy as operator. Onward's 2022 sustainability report lists the plant as a 300 MW, 100%-owned Vestas facility with a 2016 commercial-operation year. ERCOT maps the plant to the SPLAIN2_RN settlement point. The public Onward record does not identify a turbine count or model, so those details are not asserted here.

Capacity factor is average output vs. this plant's observed peak.
Observed ERCOT settlement prices at SPLAIN2_RN over 365 days (2025-10-27 to 2026-10-26).
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.
