SAN FRANCISCO, Aug 26 (Reuters) – Southern California Edison said on Wednesday it is seeking a U.S. grant to store wind power in the largest-ever grid storage battery, to be built by A123 Systems.
The utility, a unit of Edison International (EIX), wants $65 million in grants from the U.S. Department of Energy for the pilot storage project and for another project involving integration of home energy management systems into the electric grid.
The utility wants $25 million for the battery project, which would be the largest ever for power grid applications, Paul De Martini, vice president of advanced technologies, said in an interview.
U.S. utilities are racing to increase their production of electricity from renewable energy sources to meet stricter state environmental rules and to gear up for any U.S. move to regulate greenhouse gas emissions from fossil fuels.
But wind and solar are intermittent energy sources, and storing the power — at an economically viable rate — is seen as crucial to making ‘alternative’ energy truly mainstream.
Southern California Edison is seeking the money from a $615 million fund that the DOE has set up for “smart grid”-related pilot projects. Smart grid technology measures and modifies power usage in homes and businesses, improving grid reliability.
The company wants privately-held A123 Systems to assemble a utility-scale battery that would be made up of smaller batteries in an 8,000-square-foot building at an existing substation in the Tehachapi region in California.
The project is important to the California utility as it expects to have about 4,500 megawatts of wind power in the Tehachapi region by around 2015 and needs to find a way to store the power, De Martini said.
“We do recognize that there is a need for energy storage to help with mitigating some of the intermittentcy of wind,” he said.
Southern California Edison is one of the leaders in delivering renewable energy to customers. It transmitted 65 percent of all solar energy produced in the United States last year.
A123 Systems, which makes lithium-ion battery packs for use in plug-in hybrid vehicles, was one of the big winners of the competition for $1.5 billion in federal stimulus funds for companies that make advanced automotive batteries.
The Watertown, Massachusetts-based company, which counts General Electric (GE) among its shareholders, received $249 million to build a battery factory in the United States.
The approval of Southern California Edison’s application would be a big boost for A123 Systems’ push into energy storage batteries for the grid.
The result of the applications is expected in November, De Martini said.
For the second pilot project on smart grid integration, Southern California Edison is seeking $40 million from the DOE and will be working with GE, SunPower Corp (SPWRA, SPWRB) and Boeing Co (BA), he said.
Utility companies around the world are laying the groundwork to upgrade their networks with smart grid technology.
Separately, another California utility, Pacific Gas and Electric Co (PCG), is seeking $25 million from the DOE’s smart grid fund for a compressed air energy storage project, which aims to pump compressed air into an underground reservoir, using mainly wind energy produced during non-peak hours. The air would be released to generate electricity during periods of peak demand.

First Solar buys 117 MW project from solar startup
Wed Nov 4, 2009 8:39pm EST
* Solar thermal co Ausra started project in 2007
* Financial terms not disclosed
* First Solar says deal to make way for other project
LOS ANGELES, Nov 4 (Reuters) – Solar industry bellwether First Solar Inc (FSLR) said on Wednesday that it bought a 117 megawatt project in California from Kleiner Perkins-backed solar thermal start-up Ausra Inc, a move that could speed up another 550 MW project in First Solar’s pipeline.
The companies did not disclose the financial terms.
Ausra, which is also backed by Khosla Ventures, said that the sale of the project — called Carrizo Energy Solar Farm — follows its strategy to move away from developing solar projects and focus on supplying large-scale solar steam generators.
“The sale of Carrizo is another step in executing our plan,” said Tom Bartolomei, senior vice president of business development at Ausra, in a statement.
Ausra landed a power purchasing agreement with California utility PG&E (PCG) two years ago for the project, located in San Luis Obispo County. That agreement was withdrawn as part of the sale, the company said.
First Solar can use the newly acquired land to revise the layout of the larger 550 MW Topaz Solar Farm project, which has run into “concerns such as farmland conservation and wildlife needs,” said Kathryn Arbeit, who oversees Topaz.
Both projects include land near each other in San Luis Obispo County.
Shares of First Solar closed down 2 percent at $121.59 on Wednesday on the Nasdaq.
