COLGATE, a 315 MW Hydro power plant in Yuba County, California. Operated by YUBA COUNTY WATER AGENCY, commissioned 1969.

How COLGATE compares

With 315 MW of capacity, COLGATE ranks 47th among the 874 operating power plants Bywatts maps in California and 7th of the 195 operating Hydro plants in the state. It accounts for about 2.3% of California's operating Hydro capacity and 0.4% of all operating capacity in the state. Nationally it is the 64th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1969, it is older than 85% of the 859 operating California plants with a recorded commissioning year. Its operator, YUBA COUNTY WATER AGENCY, runs 3 operating plants in California totaling 364 MW. It shares Yuba County with 2 other operating plants, NARROWS 2 and DEADWOOD CREEK.

EIA-860 lists 2 generators at the site with 315 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 1,271 GWh in 2024 (a 46% capacity factor), about 2.1 times its 2022 output.

Weather peril exposure

COLGATE is a 315 MW hydro power plant in Yuba County, CA, operated by YUBA COUNTY WATER AGENCY, commissioned in 1969. Yuba County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.7 of 5 at the 18th national percentile. Wildfire is the leading peril, rated Relatively Moderate by FEMA at the 98th percentile.

The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
