WOODLEAF, a 59 MW Hydro power plant in Butte County, California. Operated by SOUTH FEATHER WATER AND POWER AGENCY, commissioned 1963.
How WOODLEAF compares
With 59 MW of capacity, WOODLEAF ranks 221st among the 874 operating power plants Bywatts maps in California and 57th of the 195 operating Hydro plants in the state. It accounts for about 0.4% of California's operating Hydro capacity and under 0.1% of all operating capacity in the state. Nationally it is the 259th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1963, it is older than 88% of the 859 operating California plants with a recorded commissioning year. Its operator, SOUTH FEATHER WATER AND POWER AGENCY, runs 4 operating plants in California totaling 123 MW. It shares Butte County with 14 other operating plants, including EDWARD C HYATT and POE.
EIA-860 lists 1 generator at the site with 67 MW of nameplate capacity, all conventional hydroelectric technology (this page's HIFLD capacity figure is 59 MW). Net generation was 194 GWh in 2024 (a 33% capacity factor), up 23% from 2022.

Weather peril exposure
WOODLEAF is a 59 MW hydro power plant in Butte County, CA, operated by SOUTH FEATHER WATER AND POWER AGENCY, commissioned in 1963. Butte County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 14th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 97th 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.

| Winter weather | Relatively Low | 1st | 1.0 of 5 | 10.9 |
Perils not assessed in Butte 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 |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
