Salt River Project completes
modernization project
The Roosevelt Dam is one of four Salt River Project hydroelectric dams along the Salt River in Arizona.
Emerson recently completed of a multi-year modernisation project at four Salt River Project( SRP) hydroelectric dams along the Salt River in Arizona. SRP’ s Roosevelt, Horse Mesa, Mormon Flat and Stewart Mountain dams generate 265 megawatts of hydropower – enough to power more than 60,000 homes annually. SRP modernised its legacy excitation systems – vital for power generation – and seamlessly integrated them with the distributed control systems already in place at its four hydroelectric dams. By standardising on Emerson’ s Ovation™
Automation Platform and implementing modern control strategies, SRP reduced operations and maintenance costs by 30 % and cut troubleshooting time by half, helping ensure operational continuity and strengthening grid performance. Enhanced operational visibility keeps critical startup and shutdown procedures efficient, avoiding delays that could have doubled their duration.
Clean, continuous power
