Tesla announced a new massive battery today called Megapack that could replace so-called “peaker” power plants, which provide energy when a local electrical grid gets overloaded. Tesla says that Pacific Gas and Electric (PG&E) will deploy several Megapacks at Moss Landing on Monterrey Bay in California, which is one of four locations where the California utility plans to install more cost-effective energy storage solutions.
Each Megapack can store up to 3 megawatt hours (MWh) of energy at a time, and it’s possible to string enough Megapacks together to create a battery with more than 1 GWh of energy storage, Tesla says. The company says this would be enough energy to power “every home in San Francisco for six hours.” Telsa will deliver the Megapacks fully assembled, and they include “battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls.” Tesla says the Megapack takes up 40 percent less space, requires a tenth of the parts to build, and can be assembled 10 times as fast as alternative energy storage solutions.
