Tesla unveils new large-scale battery, the Megapack

The Tesla Megapack

Less than two years ago Tesla installed the world’s largest lithium-ion battery in Hornsdale using Tesla’s Powerpack batteries. The project has been widely regarded as a success, saving nearly $40 million in its first year.

To match demand for massive battery storage projects like Hornsdale, Tesla has designed and engineered a new battery – the Megapack – which is specifically for ultility-scale projects.

Tesla says the 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 of storage and 1.5 MW of inverter capacity.

The Megapack builds on Powerpack’s engineering with an AC interface and 60 per cent 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.

All Megapacks connect to Powerhub, an advanced monitoring and control platform for large-scale utility projects and microgrids.
