PIT 3, an 80 MW Hydro power plant in Shasta County, California. Operated by PACIFIC GAS & ELECTRIC CO, commissioned 1925.
How PIT 3 compares
With 80 MW of capacity, PIT 3 ranks 187th among the 874 operating power plants Bywatts maps in California and 46th of the 195 operating Hydro plants in the state. It accounts for about 0.6% of California's operating Hydro capacity and 0.1% of all operating capacity in the state. Nationally it is the 211th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1925, it is older than 96% of the 859 operating California plants with a recorded commissioning year. Its operator, PACIFIC GAS & ELECTRIC CO, runs 71 operating plants in California totaling 7,904 MW. It shares Shasta County with 32 other operating plants, including SHASTA and REDDING POWER.
EIA-860 lists 3 generators at the site with 80 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 333 GWh in 2024 (a 47% capacity factor), about 3 times its 2022 output.

Weather peril exposure
PIT 3 is an 80 MW hydro power plant in Shasta County, CA, operated by PACIFIC GAS & ELECTRIC CO, commissioned in 1925. Shasta County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.8 of 5 at the 20th national percentile. Wildfire is the leading peril, rated Relatively High 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.
Shasta County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Wildfire | Relatively High | 98th | 4.9 of 5 | <0.01 |
| Earthquake | Relatively Moderate | 94th | 4.7 of 5 | 0.02 |
| Riverine flooding | Relatively High | 93rd | 4.7 of 5 | 1.0 |
| Heat wave | Relatively Moderate | 68th | 3.7 of 5 | 5.0 |
| Lightning | Relatively Moderate | 9th | 1.3 of 5 | 14.2 |
| Tornado | Very Low | 7th | 1.3 of 5 | 0.07 |
| Hail | Very Low | 3rd | 1.1 of 5 | 0.10 |
| Winter weather | Relatively Moderate | 2nd | 1.1 of 5 | 20.9 |
| Strong wind | Very Low | 1st | 1.0 of 5 | 0.02 |
Perils not assessed in Shasta 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 |
