Tesla introduces battery for utility-scale energy storage

Tesla has designed and engineered a new battery product which, it has said, is specifically for utility-scale projects.

On 29 July, it noted how it had built and installed the world’s largest lithium-ion battery in Hornsdale, South Australia, which has gone on to save almost $40mn in its first year and both stabilise and balance the region’s grid, using Tesla Powerpack batteries. With global demand for battery storage projects of the size of Hornsdale rising, it has designed the Megapack battery. Each Megapack has 3MWhs of storage and 60% greater energy density than the Powerpack, ensuring it can achieve significant cost and time savings.

By using Megapack, Tesla said it could deploy an emissions-free 250MW, 1GWh power plant in less than three months on a three-acre footprint. This would be four times faster than a traditional fossil fuel plant of that size.
