Utility-scale battery storage system for grid stabilization and renewable energy.
The Tesla Megapack is a large-scale rechargeable lithium-ion battery stationary energy storage system designed for utility and commercial projects. Each unit stores over 3.9 MWh of energy, enough to power thousands of homes, and comes pre-assembled in a weather-resistant enclosure for rapid deployment.
Megapack installations help utilities store excess solar and wind energy, provide grid stabilization services, and reduce reliance on peaker plants. Notable deployments include the Moss Landing facility in California, one of the world's largest battery storage installations, and projects across multiple continents.
