Tesla launches cloud-based massive energy storage battery range

The Megapack energy storage system comes from the factory fully-assembled with up to 3 megawatt hours (MWh) of lithium ion cells and 1.5 MW of inverter capacity with cloud-based contorl and machine learning to sell the energy.

The technology builds on Tesla's Powerpack AC interface to deploy a 250 MW, 1 GWh power plant in less than three months on a three-acre footprint, four times faster than a traditional fossil fuel power plant of that size. Megapack can also be DC-connected directly to solar, creating seamless renewable energy plants.

For utility installations like the upcoming Moss Landing project in California with PG&E, Megapack will act as a sustainable alternative to natural gas “peaker” power plants. Peaker power plants fire up whenever the local utility grid can’t provide enough power to meet peak demand. A Megapack installation can use stored excess solar or wind energy to support the grid’s peak loads.

Tesla developed its own software in-house to monitor, control and monetize Megapack installations using updates over-the-air and on the cloud servers. All Megapacks connect to Powerhub, an advanced monitoring and control platform for large-scale utility projects and microgrids, and can also integrate with Autobidder, Tesla’s machine-learning platform for automated energy trading. Tesla customers have already used Autobidder to sell more than 100 GWh of energy in global electricity markets.

In the last year Tesla has installed more than 1 GWh of global storage with Powerwall and Powerpack, doubling its installed base to 2 GWh.
