INTERNATIONAL PAPER VALLIANT OK, a 68 MW Biomass power plant in McCurtain County, Oklahoma. Operated by INTERNATIONAL PAPER - VALLIANT, commissioned 1971.
How INTERNATIONAL PAPER VALLIANT OK compares
With 68 MW of capacity, INTERNATIONAL PAPER VALLIANT OK ranks 56th among the 73 operating power plants Bywatts maps in Oklahoma and is the largest of the 2 operating Biomass plants in the state. It accounts for about 80% of Oklahoma's operating Biomass capacity and 0.3% of all operating capacity in the state. Nationally it is the 48th-largest of the 350 operating Biomass plants in the database. Commissioned in 1971, it is older than 66% of the 72 operating Oklahoma plants with a recorded commissioning year. It shares McCurtain County with one other operating plant, BROKEN BOW.
EIA-860 lists 1 generator at the site with 68 MW of nameplate capacity, all wood/wood waste biomass technology. Net generation was 451 GWh in 2024 (a 76% capacity factor), up 3% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 138 kV line owned by PUBLIC SERVICE CO OF OKLAHOMA, about 0.2 miles away. One other operating power plant sits within 25 miles: HUGO (446 MW, Coal).

Weather peril exposure
INTERNATIONAL PAPER VALLIANT OK is a 68 MW biomass power plant in McCurtain County, OK, operated by INTERNATIONAL PAPER - VALLIANT, commissioned in 1971. McCurtain County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 86th national percentile. Ice storm 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 biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
McCurtain County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Ice storm | Relatively High | 96th | 4.8 of 5 | 1.1 |
| Hail | Relatively Moderate | 87th | 4.5 of 5 | 4.9 |
| Winter weather | Relatively Low | 78th | 4.1 of 5 | 4.4 |
| Heat wave | Relatively Moderate | 77th | 4.1 of 5 | 18.4 |
| Wildfire | Relatively Low | 76th | 4.0 of 5 | <0.01 |
| Tornado | Relatively Moderate | 71st | 3.8 of 5 | 1.2 |
| Lightning | Relatively Moderate | 71st | 3.8 of 5 | 64.1 |
| Riverine flooding | Relatively Moderate | 67th | 3.7 of 5 | 2.1 |
| Earthquake | Relatively Low | 66th | 3.6 of 5 | <0.01 |
| Hurricane | Very Low | 50th | 3.0 of 5 | 0.01 |
| Strong wind | Relatively High | 38th | 2.5 of 5 | 3.4 |
Perils not assessed in McCurtain 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.
