Edison International electric utility Southern California Edison (SCE) has signed agreements for up to 960 MW of renewable power.

The recent contracts include an agreement with Columbia Energy Partners for 40 MW of wind power, expandable to 104 MW, in Central Oregon; and one with BP Wind Energy & Ridgeline Energy, LLC for 90 MW of wind power, expandable to 130 MW, in Southeast Idaho.

Both of these contracts are scheduled to come on line in the fourth quarter of 2010.

To date, SCE has executed 12 contracts from the 2008 renewable solicitation representing potential annual deliveries of more than 6.5 billion kilowatt-hours per year. In addition, SCE is in the process of preparing to issue the 2009 renewable solicitation with an expected launch date by the end of June.

SCE delivers more renewable energy to its customers than any other utility — 12.6 billion kilowatt-hours in 2008.

For SCE, these agreements follow its two wind-energy contracts signed few months ago. One agreement, with Puget Sound Energy signed in January, calls for 2 billion kilowatt-hours over the next two years. The projects are located in Columbia and Kittitas counties in Washington state. The other, with AES Mountainview, calls for 66.6 megawatts from a wind farm in the San Gorgonio Pass near Palm Springs. This 10-year contract was signed in November last year.

In February this year, it had shared that its renewables portfolio included 1,137 MW from wind.
