Solar

We are #1 in solar power among cooperative G&Ts.

Hydro

We and our members have been delivering electricity using hydro power since 1952.

Wind

We added wind power to our energy mix in 2010. This year we announced our fifth utility-scale wind project.

Homes powered

Half a million homes a year are powered by our renewable resources.

We are more than doubling our emissions-free solar energy...

Already the nation’s leading generation and transmission cooperative for solar energy, we will more than double our emissions-free renewable energy from the sun through a new 100-megawatt project with Boulder, Colorado-based juwi Inc.

Spanish Peaks Solar Project will power the equivalent of 28,000 rural homes and will sit adjacent to our 30-megawatt San Isabel Solar Project in Southern Colorado. Learn more

... and adding our fifth utility-scale wind farm

In partnership with EDP Renewables we are purchasing power from the 104-megawatt Crossing Trails Wind Farm in eastern Colorado. By 2020 when the wind farm goes live, we will power the equivalent of 47,000 rural homes.

The Crossing Trails Wind Farm is located approximately 20 miles south of the Town of Seibert and is within both Kit Carson and Cheyenne Counties. Learn more

Our renewables: nearly a third

A growing part of our energy portfolio comes directly from water, sun and wind. In fact, nearly a third of the electricity used by our cooperative consumers comes from renewable resources.

Our member systems are also using local, distributed renewable energy projects in many of their communities. Together, we generate possibilities.
