ROKEBY, a 266 MW Oil power plant in Lancaster County, Nebraska. Operated by LINCOLN ELECTRIC SYSTEM, commissioned 1975.
How ROKEBY compares
With 266 MW of capacity, ROKEBY ranks 9th among the 86 operating power plants Bywatts maps in Nebraska and is the largest of the 26 operating Oil plants in the state. It accounts for about 40% of Nebraska's operating Oil capacity and 3.2% of all operating capacity in the state. Nationally it is the 19th-largest of the 544 operating Oil plants in the database. Commissioned in 1975, it is newer than 63% of the 85 operating Nebraska plants with a recorded commissioning year. Its operator, LINCOLN ELECTRIC SYSTEM, runs 3 operating plants in Nebraska totaling 460 MW. It shares Lancaster County with 5 other operating plants, including SHELDON and TERRY BUNDY GENERATING STATION.
Under the same EIA plant code, EIA-860 lists 4 generators at the site with 266 MW of nameplate capacity. Net generation was 22.8 GWh in 2024 (a 1% capacity factor). Its generators came online between 1975 and 2001.
Grid neighborhood
The closest transmission line found within 10 miles is a 115 kV line owned by LINCOLN ELECTRIC SYSTEM, under 0.1 miles away. Another 7 operating power plants totaling 497 MW sit within 25 miles; the largest is SHELDON (229 MW, Coal).

Weather peril exposure
ROKEBY is a 266 MW oil power plant in Lancaster County, NE, operated by LINCOLN ELECTRIC SYSTEM, commissioned in 1975. Lancaster County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.7 of 5 at the 92nd national percentile. Tornado is the leading peril, rated Relatively High by FEMA at the 97th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Lancaster County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Tornado | Relatively High | 97th | 4.9 of 5 | 0.78 |
| Heat wave | Relatively Low | 94th | 4.8 of 5 | 8.3 |
| Hail | Relatively High | 93rd | 4.7 of 5 | 7.8 |
| Strong wind | Very High | 92nd | 4.7 of 5 | 4.5 |

| Winter weather | Very High | 75th | 4.0 of 5 | 13.5 |
| Ice storm | Relatively High | 74th | 4.0 of 5 | 0.88 |
| Lightning | Relatively High | 65th | 3.6 of 5 | 45.9 |
| Riverine flooding | Relatively Moderate | 15th | 1.6 of 5 | 1.4 |
| Earthquake | Very Low | 12th | 1.5 of 5 | <0.01 |
Perils not assessed in Lancaster 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 "No Rating" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
