PYRAMID, a 186 MW Natural Gas power plant in Hidalgo County, New Mexico. Operated by TRI-STATE G & T ASSN INC, commissioned 2003.
How PYRAMID compares
With 186 MW of capacity, PYRAMID ranks 11th among the 65 operating power plants Bywatts maps in New Mexico and 8th of the 16 operating Natural Gas plants in the state. It accounts for about 4.7% of New Mexico's operating Natural Gas capacity and 2.6% of all operating capacity in the state. Nationally it is the 552nd-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2003, it is older than 73% of the 63 operating New Mexico plants with a recorded commissioning year. Its operator, TRI-STATE G & T ASSN INC, runs 2 operating plants in New Mexico totaling 188 MW. It shares Hidalgo County with one other operating plant, LORDSBURG GENERATING.
EIA-860 lists 4 generators at the site with 186 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 270 GWh in 2024 (a 17% capacity factor).

Weather peril exposure
PYRAMID is a 186 MW natural gas power plant in Hidalgo County, NM, operated by TRI-STATE G & T ASSN INC, commissioned in 2003. Hidalgo County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 10th national percentile. Wildfire is the leading peril, rated Relatively Low by FEMA at the 93rd 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.
