MWD Hydropower Project


Year Built: 2008      Combined Peak Plant Capacity: 17.04 MW     Generation Type: Small Hydro

SCPPA Participants:  Anaheim,  Azusa,  Colton



About the MWD Plants

SCPPA holds a power purchase agreement for the output from four small hydroelectric plants on the Metropolitan Water District (MWD) system in Southern California, having a total nameplate capacity of 17.04 MW. The four plants are: Perris (7.94 MW), Rio Hondo (1.9 MW), Coyote Creek (3.13 MW) and Valley View (4.10 MW). Output for these plants is dependent on the water operations of MWD. Transmission is accomplished through the California Independent System Operator, with the City of Anaheim acting as the scheduler. 


Quarterly Update (October 2016)

Power production is dependent on water flow in the water distribution pipelines, similar to run-of-the-river systems. Current year increases in the amount of water allocated from the State Water Project, as well as the end to mandatory water conservation, has increased flows through Metropolitan's system. The increased flows have resulted in increased hydro power generation. As we move into fall and winter months, precipitation amounts will determine whether allocations from the State Water Project will remain at or near the present values. Another year like the last one should allow generation to continue at the current levels or potentially increase.
