Newsday: 400 megawatt battery proposed for LIPA

Energizer Bunny, step aside.

A Virginia-based company is proposing to build the country's largest battery -- one capable of storing as much energy as a large power plant -- on Long Island in response to LIPA's bid to upgrade local power sources.

If LIPA approves it, it would eliminate the need to build another plant or lay an undersea cable. The lithium-based batteries would recharge using existing power plants or cables, powering up at night when the cost is cheapest.

Power would come from the most efficient and lowest-cost sources such as Caithness power plant or Neptune Cable while they are idle.
