Arizona utilities trio looks to add nuclear power
The top three utilities in Arizona are teaming up to explore opportunities to add nuclear generation facilities in the state.
Arizona Public Service (APS), Salt River Project (SRP), and Tucson Electric Power (TEP) announced in a February 5 news release that they are working together to assess possible sites, including retiring coal plants. The group is looking at possibilities for both small modular reactors—units generating 300 MW or less—and potential large reactor projects, which could generate nearly five times the power.
