Green Power Partners


United Power customers, like Broomfield’s municipal government, can purchase carbon-free, renewable energy through United Power’s Green Power Partners program. As a Green Power Partner, Broomfield purchases renewable wind energy through Tri-State Generation & Transmission (a non-profit, cooperative power supplier in the western United States). 

Tri-State purchases wind power from Platte River Power Authority’s wind farm located near Medicine Bow, Wyoming, and from Basin Electric’s Prairie Winds Program, which consists of six wind projects totaling 85 megawatts. Wind power and other renewable resources such as small hydropower, biomass and solar energy are purchased on the open market by Tri-State.

100% of the dollars invested in this program go toward the purchase of new, renewable electric power production, such as wind, solar, and biomass, and fund research and development of emerging renewable technologies.

Broomfield is able to offset 111.7 pounds of CO2 equivalent (or CO2e) for every 100 kWh Green Power block purchased.
