Elli, a subsidiary of Volkswagen, has connected its first large-scale battery storage system to the grid in Salzgitter, with a capacity of 20 MW and 40 MWh. This facility is designed to trade energy on the European Power Exchange (EPEX) and is part of Volkswagen's strategy to enhance its role in the energy market.

The battery energy storage system consists of 13 containers and will absorb surplus electricity while providing power during high demand. This project is supported by technology from PowerCo and aims to create a comprehensive energy ecosystem linking electric mobility and energy infrastructure. Further storage projects are planned as part of the transition to renewable energy.
