CROCKETT COGEN PROJECT, a 247 MW Natural Gas power plant in Contra Costa County, California. Operated by CROCKETT COGENERATION, commissioned 1995.
How CROCKETT COGEN PROJECT compares
With 247 MW of capacity, CROCKETT COGEN PROJECT ranks 64th among the 874 operating power plants Bywatts maps in California and 39th of the 190 operating Natural Gas plants in the state. It accounts for about 0.7% of California's operating Natural Gas capacity and 0.3% of all operating capacity in the state. Nationally it is the 505th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1995, it is older than 59% of the 859 operating California plants with a recorded commissioning year. It shares Contra Costa County with 18 other operating plants, including DELTA ENERGY CENTER and MARSH LANDING GENERATING STATION.
EIA-860 lists 1 generator at the site with 247 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 1,368 GWh in 2024 (a 63% capacity factor), down 10% from 2022.
Grid neighborhood
The nearest named substation is CROCKETT (60 kV), about 0.6 miles away; the closest transmission line found within 10 miles is a 200 kV line, about 0.4 miles away. Another 37 operating power plants totaling 4,497 MW sit within 25 miles; the largest is DELTA ENERGY CENTER (944 MW, Natural Gas). Within 50 miles are 24 mapped data centers; the nearest is Level(3) Oakland in Emeryville, about 15.8 miles away.

Weather peril exposure
CROCKETT COGEN PROJECT is a 247 MW natural gas power plant in Contra Costa County, CA, operated by CROCKETT COGENERATION, commissioned in 1995. Contra Costa County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.5 of 5 at the 13th national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 99th 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.
Contra Costa County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Earthquake | Relatively High | 99th | 5.0 of 5 | 0.13 |
| Riverine flooding | Very High | 93rd | 4.7 of 5 | 1.2 |
| Wildfire | Relatively Moderate | 91st | 4.6 of 5 | <0.01 |
| Heat wave | Relatively High | 45th | 2.8 of 5 | 8.5 |
| Coastal flooding | Relatively Moderate | 41st | 2.6 of 5 | 1.5 |
| Tornado | Relatively Low | 9th | 1.4 of 5 | 0.10 |
| Hail | Very Low | 4th | 1.2 of 5 | 0.04 |
| Strong wind | Relatively Low | 2nd | 1.1 of 5 | 0.04 |
| Lightning | Relatively High | 2nd | 1.1 of 5 | 4.5 |
| Winter weather | Very Low | 1st | 1.0 of 5 | 0.44 |
Perils not assessed in Contra Costa County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
