NextEra Energy ResourcesTaylor County
Horse Hollow Wind Energy Center is a 735.5 MW wind complex in Taylor and Nolan counties, Texas. NextEra Energy Resources' project fact sheet reports 421 turbines across three phases: 142 GE 1.5 MW turbines in Horse Hollow I, 130 Siemens 2.3 MW turbines in Horse Hollow II, and 149 GE 1.5 MW turbines in Horse Hollow III. The first phase entered service in 2005-2006 and phases II and III in 2006; EIA groups the three phases under Plant ID 56291.

Project milestones and public references behind the asset profile.
EIA reports December 2005 for the 213 MW first phase; NextEra describes its operating start as 2005-2006.
Monthly generation is reported through EIA-923. Capacity factor uses the current EIA nameplate capacity and is shown only for complete calendar years.
Observed ERCOT settlement prices at HHOLLW2_WND1 over 365 days (2025-10-26 to 2026-10-25). This plant is also crosswalked to HHOLLW3_WND1, HHOLLW4_WND1, H_HOLLO_WND1; the point with the deepest price history is shown.
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.
Matched to the latest available ERCOT generation-interconnection queue record. Queue status and completion dates describe the queue record; operating status is verified separately against plant and market registrations.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
EIA reports June 2006 for the 299 MW and 223.5 MW phases.
ERCOT SCED disclosure is delayed, so plant performance windows end at the latest disclosed interval.
