TOP OF THE WORLD WINDPOWER PROJECT, a 200 MW Wind power plant in Converse County, Wyoming. One of 63 power plants tracked in Wyoming on Bywatts.
How TOP OF THE WORLD WINDPOWER PROJECT compares
With 200 MW of capacity, TOP OF THE WORLD WINDPOWER PROJECT ranks 7th among the 53 operating power plants Bywatts maps in Wyoming and is the largest of the 14 operating Wind plants in the state. It accounts for about 15% of Wyoming's operating Wind capacity and 2.3% of all operating capacity in the state. Nationally it is the 58th-largest of the 708 operating Wind plants in the database. Commissioned in 2010, it is newer than 92% of the 53 operating Wyoming plants with a recorded commissioning year. It shares Converse County with 4 other operating plants, including DAVE JOHNSTON and GLENROCK.
EIA-860 lists 1 generator at the site with 200 MW of nameplate capacity, all onshore wind turbine technology. Net generation was 342 GWh in 2024 (a 19% capacity factor), down 15% from 2022.
Grid neighborhood
The nearest named substation is WINDSTAR (230 kV), about 5.3 miles away; the closest transmission line found within 10 miles is a 115 kV line owned by PACIFICORP, about 0.2 miles away. Another 5 operating power plants totaling 1,180 MW sit within 25 miles; the largest is DAVE JOHNSTON (817 MW, Coal).

Weather peril exposure
TOP OF THE WORLD WINDPOWER PROJECT is a 200 MW wind power plant in Converse County, WY, operated by DUKE ENERGY TOP OF THE WORLD WINDPOWER, commissioned in 2010. Converse County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.1 of 5 at the 53rd national percentile. Wildfire is the leading peril, rated Relatively Moderate by FEMA at the 91st percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Converse County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Wildfire | Relatively Moderate | 91st | 4.6 of 5 | <0.01 |
| Winter weather | Relatively Moderate | 77th | 4.1 of 5 | 19.1 |
| Riverine flooding | Relatively Low | 77th | 4.1 of 5 | 0.18 |
| Earthquake | Very Low | 75th | 4.0 of 5 | <0.01 |
| Hail | Relatively Low | 62nd | 3.5 of 5 | 1.4 |
| Lightning | Relatively Low | 47th | 2.9 of 5 | 42.2 |
| Tornado | Very Low | 25th | 2.0 of 5 | 0.69 |
| Ice storm | Very Low | 24th | 2.0 of 5 | 0.02 |
| Heat wave | Very Low | 12th | 1.5 of 5 | 0.17 |
| Strong wind | Very Low | 4th | 1.2 of 5 | 0.43 |
Perils not assessed in Converse 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 |
