Utilities provide electricity at the retail and wholesale levels. Retail electric utilities provide electricity to power homes and businesses in Colorado, while wholesale electric utilities generate electricity and provide power for other utilities.
Depending on where retail customers are located within the state, customers may be served by an investor-owned utility, a cooperative utility or a municipal utility. Investor-owned utilities are for-profit corporations that are regulated by the Colorado Public Utilities Commission (PUC). Colorado has two investor-owned electric utilities -- Black Hills Energy and Public Service Company of Colorado, known as Xcel Energy. Coloradans are also served by 29 municipal utilities and 22 rural electric cooperatives. Since municipal and cooperative utilities are not operated as for-profit corporations, they are not regulated by the PUC.
