How DYNEGY MOSS LANDING POWER PLANT compares
With 2,802 MW of capacity, DYNEGY MOSS LANDING POWER PLANT is the largest of the 874 operating power plants Bywatts maps in California and the largest of the 190 operating Natural Gas plants in the state. It accounts for about 7.6% of California's operating Natural Gas capacity and 3.9% of all operating capacity in the state. Nationally it is the 6th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2002, it is older than 54% of the 859 operating California plants with a recorded commissioning year. It shares Monterey County with 10 other operating plants, including KING CITY POWER PLANT and KING CITY PEAKING.
EIA-860 lists 9 generators at the site with 2,148 MW of nameplate capacity, mainly natural gas fired combined cycle technology (this page's HIFLD capacity figure is 2,802 MW). Net generation was 3,931 GWh in 2024 (a 21% capacity factor). Its generators came online between 2002 and 2023.

Weather peril exposure
DYNEGY MOSS LANDING POWER PLANT is a 2,802 MW natural gas power plant in Monterey County, CA, operated by DYNEGY -MOSS LANDING LLC, commissioned in 2002. Monterey County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.7 of 5 at the 17th 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.

| 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 |
