Among the Nation’s Leading Utilities for Renewable Energy


Our Renewable Power Summary for 2012

Renewable power plays an important role in California's cleaner energy future. In 2012, we delivered approximately 15.01 billion kWh of renewable power – or about 19.9 percent of all the electricity we delivered that year. That's more than any other U.S. utility delivered in 2012.

Wind 2,315 6,241 41%
Geothermal 932 6,522 44%
Solar 433 1,038 7%
Small Hydro 227 628 4%
Biomass 129 614 4%
Total 4,036 15,098 100%




Renewable Power for Southern California

Wind farms and solar plants typically are located in remote areas, far from where most of us live and work. To deliver wind and solar power to Southern California homes and businesses, our infrastructure must be expanded and upgraded.  Our Tehachapi Renewable Transmission Project is the nation’s largest wind energy delivery infrastructure, and it’s one of many strategic investments we’re making to provide more renewable power.

Expanding Infrastructure for Renewable Power

Solar Power on Warehouse Rooftops

Our innovative Rooftop Solar Program – the nation’s largest advanced solar photovoltaic project – is generating cleaner renewable power in an environmentally sustainable fashion. By positioning solar stations on the roofs of existing warehouses in sunny, inland areas, we are putting otherwise-unused rooftops to good use. The program is designed to generate as much as 220 megawatts DC of solar power with rooftop and ground mounted photovoltaic panels, both by us and by independent power producers.

Helping Californians Go Solar

We have helped many thousands of homeowners, businesses, and multi-family residences harness the sun’s power with California Solar Initiative rebates. As of July 2012, we have reserved solar incentives for more than 38,000 customers for a total of $749 million in rebates.


100+ Years of Clean Hydropower

We have been generating hydro power in the Sierra Nevada Mountains for 100+ years. Big Creek was the first large-scale hydro system in the United States. Today, it generates enough emission-free electricity to power 640,000 homes, and accounts for 20% of the generation capacity we own. We don’t count it toward our renewable portfolio standard goals, though, because California policy does not include power from large hydro plants.
