Already having claimed a large chunk of the C&I and utility-scale energy storage market, Tesla now announced a new energy storage solution. The Tesla Megapacks are aimed at replacing ‘peaker’ power plants; can store up to 3 MWh of power; and can be stringed together to create a huge battery with as much as 1 GWh of storage capacity. California’s PG&E has already signed on to deploy several Megapacks.
