At the site level, Megapack requires 40% less space and 10x fewer parts than current systems on the market. As a result, this high-density, modular system can be installed 10x faster than current systems.
Less than two years ago, Tesla built and installed the world's largest lithium-ion battery in Hornsdale, South Australia, using Tesla Powerpack batteries. Since then, the facility saved nearly $40 million in its first year alone and helped to stabilize and balance the region's unreliable grid.
Battery storage is transforming the global electric grid and is an increasingly important element of the world's transition to sustainable energy. To match global demand for massive battery storage projects like Hornsdale, Tesla designed and engineered a new battery product specifically for utility-scale projects: Megapack.
Megapack significantly reduces the complexity of large-scale battery storage and provides an easy installation and connection process. Each Megapack comes from the factory fully-assembled with up to 3 megawatt hours (MWhs) of storage and 1.5 MW of inverter capacity, building on Powerpack's engineering with an AC interface and 60% increase in energy density to achieve significant cost and time savings compared to other battery systems and traditional fossil fuel power plants. Using Megapack, Tesla can deploy an emissions-free 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.
