How ARTHUR VON ROSENBERG compares
With 550 MW of capacity, ARTHUR VON ROSENBERG ranks 69th among the 307 operating power plants Bywatts maps in Texas and 54th of the 134 operating Natural Gas plants in the state. It accounts for about 0.8% of Texas's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 299th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2000, it is older than 52% of the 303 operating Texas plants with a recorded commissioning year. Its operator, CITY OF SAN ANTONIO - (TX), runs 6 operating plants in Texas totaling 5,341 MW. It shares Bexar County with 9 other operating plants, including J K SPRUCE and V H BRAUNIG.
EIA-860 lists 3 generators at the site with 575 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 3,020 GWh in 2024 (a 60% capacity factor), up 14% from 2022.

Weather peril exposure
ARTHUR VON ROSENBERG is a 550 MW natural gas power plant in Bexar County, TX, operated by CITY OF SAN ANTONIO - (TX), commissioned in 2000. Bexar County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.8 of 5 at the 95th national percentile. Hail is the leading peril, rated Very High by FEMA at the 96th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Bexar County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Very High | 96th | 4.8 of 5 | 3.0 |
| Riverine flooding | Very High | 67th | 3.7 of 5 | 7.5 |
| Wildfire | Relatively Moderate | 51st | 3.0 of 5 | <0.01 |
| Hurricane | Relatively Moderate | 49th | 3.0 of 5 | 0.04 |
| Tornado | Very High | 44th | 2.8 of 5 | 0.43 |
| Heat wave | Relatively High | 20th | 1.8 of 5 | 10.3 |
| Ice storm | Relatively Moderate | 17th | 1.7 of 5 | 0.19 |
| Winter weather | Relatively High | 9th | 1.4 of 5 | 2.8 |
| Lightning | Relatively High | 8th | 1.3 of 5 | 46.0 |
| Strong wind | Relatively High | 6th | 1.2 of 5 | 1.00 |
| Earthquake | Relatively Low | 5th | 1.2 of 5 | <0.01 |
Perils not assessed in Bexar County
