The facility originally came online in December 2012, with 42 1.6 MW turbines, producing 67 MW of power. The expansion, which was announced in April and began construction in July, consists of an additional 14 1.7 MW GE turbines, increasing the facility’s total current capacity by 36 per cent.

Tri-State Generation and Transmission Association Inc has a 20-year power purchase agreement to receive all the electricity and environmental attributes from the wind farm.

“Colorado Highlands Wind has been performing extremely well since being brought on-line late last year,” said Tri-State senior vice president Brad Nebergall. “Since it was originally designed to accommodate 91 MWs on the existing transmission system – and since Tri-State is always proactively pursuing projects that make sense for us and our member electric co-ops – the expansion of Colorado Highlands Wind was an opportunity we quickly embraced.”
