Power Generation

We make electricity


We operate major generating facilities that use a variety of fuel sources including coal, natural gas, nuclear fuel, water (hydro), oil, and refuse; we also have facilities that generate electricity from the wind and sun. In total, our plants are capable of producing more than 17,000 megawatts (MW) of electricity. One megawatt of power generated by fossil fuels or nuclear fuel provides enough electricity to serve 750 typical homes. 

We generate approximately two-thirds of our power and buy the remainder from other electricity suppliers to meet our customers’ energy needs. We have a diverse fuel mix.

Generating Facilities

2013 Owned Generating Plants

Type Plants Units Summer Net Dependable Capacity in Megawatts (MW)*
Coal 13 27 7,597
Natural gas 27 69 6,758
Nuclear 2 3 1,594
Hydro 26 79 377
Diesel/Oil 2 14 383
Refuse-derived fuel 3 6 52
Wind 3 238 42*
Solar 4 4 0.01
Total 77 owned generating plants 440 16,785

*Net generating capacity is 327 MW for Xcel Energy owned wind energy facilities. Summer net dependable capacity is determined to be lower because wind generation is an intermittent resource and is only available when ambient wind conditions exist.
