Colorado Electric Utilities
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.

Electric Resource Adequacy Reporting
As required in HB23-1039, each electric utility providing retail or wholesale
electricity services is required to submit an annual report detailing the adequacy of
its electric resources to its regulating authority. The Colorado Energy Office
aggregates these reports to assess reliability and electric resource adequacy as
Colorado transitions to clean electricity.
