Tesla launches the “Megapack”, a plug and play system for utility energy storage

Tesla said the Megapack will arrive preassembled, pretested in one enclosure from its Gigafactory and deployable in 3-months


Battery storage is transforming the global electric grid and is an increasingly important element of the world’s transition to sustainable energy.

What Happened?

Tesla has designed and engineered a new battery product specifically for utility-scale projects called the “Megapack”.

Tesla says each Megapack comes fully-assembled with up to 3 megawatt hours (MWhs) of storage and 1.5 MW of inverter capacity. Adding that a megapack can be fully deployed in less than three months on a three-acre footprint for a 250 MW, 1 GWh power plant.

It packs an AC interface and 60 percent increase in energy density, over the Powerpack, to achieve significant cost and time savings.

Why It Matters

Because some renewable energy technologies, such as solar, have variable outputs, storage technologies have great potential for smoothing out the electricity supply from these sources and ensuring that the supply of generation matches the demand.

If you remember about 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.

As the world’s transition to sustainable energy continues to accelerate, the market for advanced battery storage solutions is growing rapidly.
