GREEN PETER, an 80 MW Hydro power plant in Linn County, Oregon. Operated by USACE NORTHWESTERN DIVISION, commissioned 1967.
How GREEN PETER compares
With 80 MW of capacity, GREEN PETER ranks 34th among the 130 operating power plants Bywatts maps in Oregon and 12th of the 58 operating Hydro plants in the state. It accounts for about 1.0% of Oregon's operating Hydro capacity and 0.5% 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 1967, it is older than 67% of the 128 operating Oregon plants with a recorded commissioning year. Its operator, USACE NORTHWESTERN DIVISION, runs 13 operating plants in Oregon totaling 6,521 MW. It shares Linn County with 5 other operating plants, including CARMEN SMITH and EVERGREEN BIOPOWER LLC.
EIA-860 lists 2 generators at the site with 80 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 155 GWh in 2024 (a 22% capacity factor), down 30% from 2022.

Weather peril exposure
GREEN PETER is an 80 MW hydro power plant in Linn County, OR, operated by USACE NORTHWESTERN DIVISION, commissioned in 1967. Linn County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 9th national percentile. Earthquake is the leading peril, rated Relatively Moderate 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.
Linn County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Earthquake | Relatively Moderate | 96th | 4.9 of 5 | 0.02 |
| Strong wind | Relatively High | 77th | 4.1 of 5 | 0.05 |
| Heat wave | Relatively Moderate | 67th | 3.7 of 5 | 5.1 |
| Riverine flooding | Relatively Moderate | 65th | 3.6 of 5 | 0.25 |
| Wildfire | Very Low | 41st | 2.7 of 5 | <0.01 |
| Ice storm | Relatively Low | 26th | 2.0 of 5 | 0.39 |
| Hail | Very Low | 16th | 1.6 of 5 | 0.23 |
| Lightning | Relatively Moderate | 9th | 1.4 of 5 | 7.4 |
| Tornado | Very Low | 8th | 1.3 of 5 | 0.13 |
| Winter weather | Relatively Moderate | 6th | 1.2 of 5 | 23.0 |
Perils not assessed in Linn 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 |
