On April 30, 2015, Tesla announced that it would sell standalone battery storage products to consumers and utilities. Tesla CEO stated that the company's battery storage products could be used to improve the reliability of intermittent renewable energy sources, such as solar and wind. Prior to the Megapack launch, Tesla used its 200 kilowatt-hour (kWh) Megapacks are designed for large-scale energy storage. Megapacks are used by utilities to replace or augment peaker power plants, [21] which generate energy during periods of peak demand. Megapacks store grid energy rather than generating it from fuel.

These systems are designed to store energy from renewable sources or the grid and release it when required. This setup offers a modular and scalable solution to energy storage.
