Southern California Edison, a subsidiary of Edison International, signed six new renewable energy contracts, the utility company said.

The agreements, Edison said, are still subject to approval by the California Public Utilities Commission and tap four separate generation types: wind, solar, biomass and geothermal.

Southern California Edison’s renewable portfolio can now deliver more than 2,700 mega-watts of electricity. One megawatt is enough to serve about 650 regular homes.

This announcement comes less than a month after Edison agreed to purchase 300 wind-power turbines from an Indian manufacturer and six months after the utility signed the largest wind-power deal ever for a U.S.-based utility when it bought 1,500 megawatts of electricity from an Australian-owned power plant.

All of this comes amid California’s goal to have 20 percent of the state’s electricity be produced from renewable sources in addition to hydroelectrical power by 2010. At the end of 2005, 17 percent of the electricity delivered by So Cal Edison, was generated by using renewable sources such as wind power.

Shares in Edison were 79 cents, or 1.4 percent, to $59.61 in afternoon trading Monday on the New York Stock Exchange.
