Tesla has introduced the Megapack, a battery the size of a shipping container designed to kill coal- and gas-fired “peaker” power plants - providing 'dispatchable generation'. Tesla is pitching the Megapack batteries as a more climate-friendly alternative that can store renewable energy when electricity demand is low, and then pump power or 'dispatch' back onto the grid when demand peaks.
Tesla installed its biggest battery installation ever - 730MwH - in April 2022 (photo above), which will help California power utility Pacific Gas and Electric replace natural gas plants it plans to phase out starting in 2023.
