INTERNATIONAL PAPER RIVERDALE MILL, a 104 MW Biomass power plant in Dallas County, Alabama. Operated by INTERNATIONAL PAPER CO-RIVERDL, commissioned 1967.
How INTERNATIONAL PAPER RIVERDALE MILL compares
With 104 MW of capacity, INTERNATIONAL PAPER RIVERDALE MILL ranks 34th among the 64 operating power plants Bywatts maps in Alabama and 2nd of the 10 operating Biomass plants in the state. It accounts for about 17% of Alabama's operating Biomass capacity and 0.3% of all operating capacity in the state. Nationally it is the 15th-largest of the 350 operating Biomass plants in the database. Commissioned in 1967, it is older than 57% of the 64 operating Alabama plants with a recorded commissioning year.
Under the same EIA plant code, EIA-860 lists 4 generators at the site with 104 MW of nameplate capacity. Net generation was 562 GWh in 2024 (a 61% capacity factor), up 41% from 2022. Its generators came online between 1967 and 1994.
Grid neighborhood
The closest transmission line found within 10 miles is a 115 kV line owned by ALABAMA POWER CO, under 0.1 miles away. Another 6 operating power plants totaling 3,439 MW sit within 25 miles; the largest is E B HARRIS ELECTRIC GENERATING PLANT (1,304 MW, Natural Gas).

Weather peril exposure
INTERNATIONAL PAPER RIVERDALE MILL is a 104 MW biomass power plant in Dallas County, AL, operated by INTERNATIONAL PAPER CO-RIVERDL, commissioned in 1967. Dallas County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.2 of 5 at the 30th national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 85th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Dallas County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Riverine flooding | Relatively Moderate | 85th | 4.4 of 5 | 0.50 |
| Earthquake | Relatively Low | 79th | 4.2 of 5 | <0.01 |
| Tornado | Relatively Moderate | 78th | 4.1 of 5 | 0.76 |
| Hurricane | Relatively Low | 75th | 4.0 of 5 | 0.08 |
| Strong wind | Relatively Moderate | 74th | 4.0 of 5 | 1.4 |
| Lightning | Relatively High | 50th | 3.0 of 5 | 69.8 |
| Heat wave | Relatively Moderate | 44th | 2.8 of 5 | 10.0 |
| Ice storm | Relatively Low | 41st | 2.7 of 5 | 0.32 |
| Wildfire | Very Low | 35th | 2.4 of 5 | <0.01 |
| Hail | Relatively Low | 28th | 2.1 of 5 | 2.1 |
| Winter weather | Very Low | 11th | 1.4 of 5 | 1.3 |
Perils not assessed in Dallas 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.
