Arizona-based Salt River Project (SRP), one of the nation’s largest public power utilities, has selected Emerson to modernize the controls of multiple hydropower units and its central service center. SRP provides electricity to 1 million customers in the metropolitan Phoenix area and is also one of the largest raw-water suppliers in Arizona, delivering approximately 800,000 acre-feet of irrigation water annually. The SRP hydro fleet comprises eight units at four sites – Roosevelt Dam, Stewart Mountain, Mormon Flat and Horse Mesa – that are controlled by SRP’s Grid Operations in Scottsdale, Arizona.
During the first phase of the project, expected to be complete in the spring of 2018, Emerson will replace controls at Roosevelt Dam, Stewart Mountain and the East Valley Service Center. In phase two, controls at the Mormon Flat and Horse Mesa sites will be upgraded.
