Wind Energy

In 1998, Tri-State began purchasing wind generation from a Wyoming wind site under an interim agreement with PacifiCorp. A year later, the G&T signed a 15-year agreement with Platte River Power Authority of Fort Collins, Colo., to purchase energy from that utility's wind farm near Medicine Bow, Wyo. Currently, Tri-State purchases approximately 153 megawatt-hours of wind power per month from that site.

As a member of Basin Electric Power Cooperative in Bismarck, N.D., Tri-State also purchases a portion of its available wind generation from Basin's Prairie Winds Program. Prairie Winds is comprised of six wind project sites totaling 85 megawatts of capacity.
