DRUM 2, a 53 MW Hydro power plant in Placer County, California. Operated by PACIFIC GAS & ELECTRIC CO, commissioned 1965.
How DRUM 2 compares
With 53 MW of capacity, DRUM 2 ranks 241st among the 874 operating power plants Bywatts maps in California and 60th 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 271st-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1965, it is older than 87% 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 Placer County with 17 other operating plants, including ROSEVILLE ENERGY PARK and MIDDLE FORK.
EIA-860 lists 1 generator at the site with 53 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 149 GWh in 2024 (a 32% capacity factor), down 43% from 2022.

Weather peril exposure
DRUM 2 is a 53 MW hydro power plant in Placer County, CA, operated by PACIFIC GAS & ELECTRIC CO, commissioned in 1965. Placer County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.3 of 5 at the 7th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 96th 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.
Placer County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Wildfire | Relatively High | 96th | 4.8 of 5 | <0.01 |
| Earthquake | Relatively Moderate | 86th | 4.5 of 5 | 0.03 |
| Riverine flooding | Relatively High | 69th | 3.8 of 5 | 1.1 |
| Heat wave | Relatively Low | 61st | 3.4 of 5 | 4.3 |
| Tornado | Very Low | 7th | 1.3 of 5 | 0.14 |
| Strong wind | Relatively Low | 3rd | 1.1 of 5 | 0.07 |
| Lightning | Relatively High | 2nd | 1.1 of 5 | 14.2 |
| Winter weather | Relatively Low | 1st | 1.0 of 5 | 27.2 |
| Hail | Very Low | 1st | 1.0 of 5 | 0.16 |
Perils not assessed in Placer 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 |
