Arizona utility Tucson Electric Power has today filed its 2020 integrated resource plan with the US state’s regulator that includes 2457MW of new wind and solar capacity by 2035.
Tucson Electric Power, which is owned by Fortis, filed the plan with the Arizona Corporation Commission.
About 457MW of wind and solar is planned to come online in the next 12 months.
The company said it is working to complete two large New Mexico wind farms and a local solar plus storage project that will more than double its community-scale clean energy resources by next year.
The plan calls for enough new wind and solar capacity to provide more than 40% of the company’s power in 2030, over 60% by 2033 and 70% by 2035.
Tucson Electric Power also aims to develop 1.4GW of energy storage and reduce carbon emissions by 80% by 2035.
The company also proposes ramping down output and ultimately retiring its two generating units at the coal-fired Springerville plant in 2027 and 2032.
“The timeline would allow TEP to reduce the plant’s workforce through attrition while providing time for the company to help the local community minimise the impact of the units’ retirement,” it added.
Tucson Electric Power chief executive David Hutchens said: “TEP is accelerating its transition to cleaner energy resources through a cost-effective plan that supports reliable, affordable service from increasingly sustainable resources
“We’ll be reducing carbon emissions at a pace that places us at the forefront of global efforts to combat climate change.”
