Tuscon Electric Power announced it plans to add 800 MW of renewable energy by 2030, which would increase the share of power generated by renewables to 30 percent.
Recently, TEP agreed to purchase power from a 100-MW wind facility developed by NextEra Energy Resources, and is evaluating proposals for a 100-MW solar facility that would be built and owned by a project partner.
Additionally, TEP plans greater use of energy storage systems, and anticipates adding up to 100 MW of storage capacity. The utility just completed three energy storage projects with a combined capacity of 2 MW.
As for coal, TEP plans to retire Unit 2 at the San Juan Generating Station in New Mexico by the end of the year, and will stop using the plant entirely in June 2022. The company is also preparing for the retirement of the coal-fired Navajo Generating Station, of which TEP owns 7.5 percent.
At the same time, the utility confirmed it will continue operating at least some coal facilities.
“Our plan recognizes the continued financial and operational benefits of owning Units 1 and 2 at the Springerville Generating Station, Arizona’s most efficient, cost-effective coal-fired power plant,” Hutchens said. “However, renewable energy, energy efficiency and cost-effective natural gas technologies will play an increasingly prominent role in our future resource plans.”
