BMW’s battery storage farm at its Leipzig production facility connects old EV batteries into a large-scale storage system that balances local wind energy.

EVs are forecast to account for 95 GWh of used battery capacity by 2025, no longer suitable for mobility uses, but major manufacturers are starting to see this as a new resource, not a problem. BMW is driving change in the industry with its battery storage farm, which connects 700 BMW i3 high-capacity batteries to onsite wind resources and the local grid, with enough storage capacity to power 50,000 homes for one month. The modular system provides grid balancing and increased security of supply, saves on energy costs by absorbing electricity when prices are low, and increases the adoption and growth of renewable energy and EVs in Germany.

How the Global Goals are addressed

Industry, Innovation, and Infrastructure

BMW’s cyclical approach, using old products to assist its transition to a low-carbon economy, can show other firms how to become more sustainable

Responsible Consumption and Production

The life-cycle approach demonstrates a new circular business model and reduces the environmental footprint of EVs.

Life on Land

Mining the resources needed to produce batteries has been linked to soil and water pollution. Finding a second use for EV batteries can help alleviate these concerns.
