In September 2000, Senate Bill 552 granted the Water Authority substantial new authority to enter the electric and natural gas wholesale markets. SB 552 modified the County Water Authority Act to allow hydroelectric power generated by the Water Authority's water delivery system to be sold to any retail electric provider. The bill also authorized the Water Authority to purchase federal power; to construct, own, and operate electric power generation facilities to service its or its member agencies' needs; and to purchase and transport natural gas.
In January 2007, the Water Authority finished construction of the Rancho Peñasquitos Hydroelectric Facility. Since being placed in service, there has been over 153,000 megawatt hours of clean renewable energy produced, generating approximately $8 million in revenue.
In August 2012, the Water Authority completed construction of a pumped storage facility at Lake Hodges. For 2016 the two generators have been available over 97% of the time with the ability to produce 40 megawatts of energy for peak demand periods. Revenue generated to date exceeds $12 million.
The construction of solar generating facilities at three locations in 2011 produce about 2,900 megawatt hours of green energy annually.
