NOTREES WINDPOWER, a 189 MW Wind power plant in Ector County, Texas. Operated by DUKE ENERGY DEGS NOTREES, commissioned 2009.
How NOTREES WINDPOWER compares
With 189 MW of capacity, NOTREES WINDPOWER ranks 131st among the 307 operating power plants Bywatts maps in Texas and 20th of the 94 operating Wind plants in the state. It accounts for about 1.6% of Texas's operating Wind capacity and 0.2% of all operating capacity in the state. Nationally it is the 84th-largest of the 708 operating Wind plants in the database. Commissioned in 2009, it is newer than 76% of the 303 operating Texas plants with a recorded commissioning year. It shares Ector County with 3 other operating plants, including ODESSA ECTOR GENERATING STATION and QUAIL RUN ENERGY CENTER.
EIA-860 lists 3 generators at the site with 189 MW of nameplate capacity, mainly onshore wind turbine technology. Net generation was 261 GWh in 2024 (a 16% capacity factor), down 15% from 2022. Its generators came online between 2009 and 2012.

Weather peril exposure
NOTREES WINDPOWER is a 189 MW wind power plant in Ector County, TX, operated by DUKE ENERGY DEGS NOTREES, commissioned in 2009. Ector County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.9 of 5 at the 98th national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 98th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Ector County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively High | 98th | 4.9 of 5 | 3.9 |
| Winter weather | Very High | 75th | 4.0 of 5 | 5.7 |
| Wildfire | Relatively Low | 71st | 3.8 of 5 | <0.01 |
| Heat wave | Relatively Moderate | 60th | 3.4 of 5 | 6.1 |
| Ice storm | Relatively Moderate | 46th | 2.8 of 5 | 0.42 |
| Tornado | Relatively Moderate | 45th | 2.8 of 5 | 0.36 |
| Strong wind | Relatively High | 34th | 2.4 of 5 | 1.5 |
| Lightning | Relatively High | 33rd | 2.3 of 5 | 43.5 |
| Riverine flooding | Relatively Moderate | 20th | 1.8 of 5 | 3.9 |
| Hurricane | Very Low | 18th | 1.7 of 5 | <0.01 |
| Earthquake | Very Low | 15th | 1.6 of 5 | <0.01 |
