Generating Capacity in
Nebraska by Energy Source

As of 2015, Nebraska had 847 generating units with a total of 9,330,426.6 kilowatts (or 9,330.4 megawatts) capacity. These units had 8,702,423.6 kilowatts (or 8,702.4 megawatts) net summer capacity and 8,400,523.6 kilowatts (or 8,400.5 megawatts) net winter capacity.

pie chart showing Generating Nameplate Capacity by Energy Source in Nebraska, for 2013.

Most of the nameplate capacity came from generators using coal (45.8 percent), natural gas (22.7 percent), nuclear energy (14.0 percent), wind (10.0 percent), petroleum (3.9 percent), and hydroelectric power (3.6 percent).

Net metered renewable installations are not included in the graphs and table since individual projects are not reported; hence, no energy sources are reported.

The Units and Capacity by Energy Source and Year of Initial Operation report, the Generating Units report, and the Annual Electricity Generation report are available for additional information.

A Note About Nameplate Capacity

Summer capacity and winter capacity are 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, you expect summer and winter capacity to be below nameplate capacity and in most cases they are.
