Southern California Edison Awards Contracts for Rooftop Solar Projects

Published July 27, 2010

Southern California Edison has awarded 36 contracts to independent power producers to install solar photovoltaic panels in its service area totaling nearly 60 megawatts of generating capacity.

Most of the projects will be rooftop installations on warehouses and other buildings in the metropolitan region that stretches east from Los Angeles. Five of the arrays will be ground-mounted.

The 36 projects are part of a plan approved by the California Public Utilities Commission in June 2009 that calls for a total of 500 megawatts of solar generating capacity, most of it on otherwise unused large warehouse rooftops.

Half of the 500 megawatts will be from independent power producers who respond to SCE’s request for offers under competitive solicitations. The remaining 250 megawatts will be owned and operated by the utility. It is expected that the overall project will create about 1,200 jobs for Southern Californians.

"These contracts make significant strides toward distributed renewable generation for one of the most innovative solar programs in the country," said Marc Ulrich, the utility company's  vice president for Renewable and Alternative Power, in a news release. "We’re working to help California meet its Million Solar Roofs goal and supply even more renewable energy to our customers where and when it’s most needed, without the added time and expense to construct major new transmission facilities."

Southern California Edison expects that the 500-mw project, when complete, will result in solar PV modules covering area totaling about 4 square miles, on about 250 otherwise unused rooftops.

For comparison, large-scale conventional power plants generally range from a few hundred megawatts of capacity to more than 1,000 mw.  

"SCE believes that its solar rooftop project will be a boon for the solar industry and consumers alike, with the resulting cost per unit significantly more cost-effective than more common residential photovoltaic installations in California," the company's news release said. "Eventually, this could help drive down installation costs of photovoltaic generation for everyone."

The majority of the solar projects for which contracts have been signed are expected to be completed in 2011 or 2012. Solar generating capacity of 500 mw in the inland areas of Southern California might be expected to provide enough electricity on an annual basis to supply as many as 100,000 households with yearly usage of about 7,200 kilowatt-hours each.

The company said it has already installed panels on three rooftop warehouses in Southern California’s Inland Valley that are now delivering – or are in line to soon deliver – electricity to the grid. Following are the 36 projects in the utility's service area:
