Generating Units in Nebraska
The units generating electricity are listed in the table below, each with unit ID, capacity, prime mover, energy source, year of commercial operation, status, number of wind turbines if applicable, and the generation sector. The key to the abbreviations is below the table.
While individual installations are not reported in available Net Metering Reports for Nebraska, the assumption was made that small–scale projects are in the net metering reports. So megawatts from the net metering reports are included in the totals below while megawatts from the known small–scale projects are not included in the totals to avoid possible double–counting.
See the Units and Capacity by Energy Source and Year of Initial Operation report and the Units and Capacity by Energy Source report for additional information.
A Note About Nameplate Capacity
Summer capacity and winter capacity is sometimes greater than nameplate capacity. The nameplate gives the capacity rating of the generator when it operates at certain temperatures, pressures, and power factors. With some modifications and with some margins that are built into generators, it is possible to exceed its nameplate. It is not uncommon for a generator to exceed its nameplate. The nameplate is usually not replaced and, in this case, the summer and winter capacity is often much higher than the nameplate value. Normally, summer and winter capacity is expected to be below nameplate capacity and in most cases they are.
