World's Largest Storage Battery Will Power Los Angeles

Posted by K R on

By 2021, electricity use in the west Los Angeles area may be in for a climate change-fighting evolution. For many years, the tradition has been that on midsummer afternoons, engineers will turn on what they call a “peaker,” a natural gas-burning power plant In Long Beach. It is needed to help the area’s other power plants meet the day’s peak electricity consumption. Thus, as air conditioners max out and people arriving home from work turn on their televisions and other appliances, the juice will be there. Five years from now, if current plans work out, the “peaker” will be gone, replaced by the world’s largest storage battery, capable of holding and delivering over 100 megawatts of power an hour for four hours. The customary afternoon peak will still be there, but the battery will be able to handle it without the need for more fossil fuels. It will have spent the morning charging up with cheap solar power that might have otherwise been wasted. Read More: Scientific American
