Salt River Project (SRP) on Tuesday delivered a record amount of energy to its Phoenix-area retail customers. Between 5 and 6 p.m., SRP delivered an estimated retail peak demand of 7,252 megawatts. That peak topped SRP’s previous system peak of 7,219 megawatts, which occurred on June 20, 2017.  One megawatt is enough energy to power about 225 average homes.

Strong customer demand is the result of several factors, including a series of extreme daytime temperatures, higher overnight temperatures and an increase in the number of SRP electric customers.   The high temperature recorded on Tuesday was 116.

SRP, which serves more than 1 million customers in the Phoenix metropolitan area, has been able to meet the increased demand thanks to a robust electrical grid maintained year-round to provide reliable service.
