TUCSON, Ariz. -- Arizona regulators have given Tucson Electric Power Co. the green light to purchase electricity generated by a planned wind and solar farm near Willcox.
The Arizona Corporation Commission approved the 20-year power purchase agreement between the utility and Red Horse Wind this week.
Construction is expected to start later this year, with the farm going online sometime in 2014.
The Arizona Daily Star reports the farm would be the first utility-scale project of its kind in southern Arizona.
Tucson Electric will be able to buy most of the plant's capacity starting in December 2014. That includes 51 megawatts of wind-generated power and 3 megawatts of solar energy.
The state has mandated that regulated utilities get power equal to 15 percent of their retail sales from renewable sources by 2025.
