A power-line project to connect what will be Southern Arizona’s biggest solar-energy farm to Tucson Electric Power Co.’s grid is headed to final approval by state regulators.
In late September, TEP won approval from the Arizona Power Plant and Line Siting Committee to build a new substation and transmission lines along South Swan Road to bring a future 100-megawatt solar farm and linked 30MW battery storage project online.
The Arizona Corporation Commission must still give its final approval, following the line-siting panel’s approval of a required certificate of environmental compatibility for the project.
