SunEdison, Inc. has secured 20-year power purchase contracts with Southern California Edison to build 33 megawatts of rooftop arrays on industrial buildings in Southern California. Once the rooftop arrays are complete, SunEdison’s public traded yieldco unit TerraForm Power Inc. will purchase the systems. 

The 17 systems are expected to be operational next year, and will be located in Orange, Riverside, San Bernardino and Los Angeles Counties.
