Generating Units and Capacity in
Nebraska by Energy Source

At the end of 2013, Nebraska had 602 generating units with a total of 8,926,597.4 kilowatts (or 8,926.6 megawatts) capacity. These units had 8,448,794.4 kilowatts (or 8,448.8 megawatts) net summer capacity and 8,207,094.4 kilowatts (or 8,207.1 megawatts) net winter capacity.

Over half, or 61.46 percent, of the generating units used renewable fuels (hydroelectric power, wind, biomass, landfill gas, and solar) which contributed 10.48 percent of the generating nameplate capacity. Sixteen and three–tenths (16.3) percent—nearly one–fifth—of the units used petroleum which contributed 4 percent of Nebraska's electricity capacity. Four and five–tenths (4.5) percent of the generating units used natural gas which contributed 23.5 percent of Nebraska's electricity capacity—nearly one–fourth of the electricity capacity. Three and three–tenths (3.3) percent of the generating units used coal which contributed 47.5 percent of the state's electricity generating capacity, and less than one percent of the units used nuclear energy which contributed 14.5 percent.

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

Most of the nameplate capacity came from generators using coal (47.5 percent), natural gas (23.5 percent), nuclear energy (14.5 percent), wind (6.7 percent), petroleum (4.0 percent), and hydroelectric power (3.7 percent).

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

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.
