SoCal Edison Wants A123 to Build Biggest Grid Battery Ever
The story talks about how Southern Cal Edison has some wind power plant they'll build by 2015 and are looking at power storage systems to store electricity and release for later. Wind power is intermittent and isn't necessarily going to be available when it's most needed (at 3:30 pm on hot summer afternoons).
They're looking for a DOE grant "to build the world's biggest lithium-ion grid storage battery" which are targeted to draw from the "$615 million smart grid demonstration grant program created in June". They "wants A123 to assemble a 32-megawatt-hour battery out of racks of smaller batteries in a 8,000-square-foot building at a substation in the Tehachapi Mountains. That battery would stabilize the flow of wind power from the mountains to the utility's load centers to the west and south, De Martini said."
