Tesla and PG&E recently broke ground on a record-setting energy storage system in Moss Landing (Monterey) California that, once complete, will be the largest such installation in the world. The battery park will be able to dispatch up to 730 megawatt hours (MWh) of energy to the electrical grid at a maximum rate of 182.5 MW for up to four hours using 256 of Tesla’s lithium-ion (Li-ion) Megapacks. Tesla and PG&E will have the option to upgrade Moss Landing’s capacity to bring the system up to 1.2-gigawatt-hours which could, according to Tesla, power every home in San Francisco for six hours.
