5 Facts About the Elli PowerCenter

Elli is currently building one very important link between e-mobility and renewable energy: the Elli PowerCenter. Using advanced battery technology, 40 MWh of storage capacity, and 20 MW of power, it does more than just store electricity. Together with Elli’s energy and charging solutions, the PowerCenter creates an intelligent energy ecosystem that connects vehicles, businesses, and the power grid. 

But the PowerCenter can do even more: it is a central component of Elli’s energy trading activities, supports security of supply, and demonstrates how renewable energy can be used efficiently. Behind the scenes, specialists are already working to ensure that the batteries of the Volkswagen Group not only power vehicles but could one day supply entire cities with clean electricity. 

In our article, you will discover 5 exciting facts about the Elli PowerCenter that show how this project is actively shaping the energy transition and defining the future of mobility. 

 1. Location 

The Elli PowerCenter is being built at the production and development site of the Volkswagen Group in Salzgitter – the location where the battery production of the future is already taking shape. 

2. Technical data 

Across an area of around 2,500 square meters, 13 containers measuring approximately six meters in length will be installed. They contain the core technical components of the storage system: inverters, transformers, and high-performance battery storage units with a total output of 20 megawatts and a storage capacity of 40 megawatt-hours (MWh). Each container of the Elli PowerCenter contains 12,960 PowerCo Unified Cell battery cells. 

3. Battery tech 

The storage solution is based on battery packs from PowerCo, a Volkswagen Group subsidiary, manufactured using the so-called Unified Cell technology (e.g., LFP – lithium iron phosphate). This enables a direct transfer of cell and battery technology from automotive production to stationary applications – a forward-looking step toward a holistic battery ecosystem. 

4. Scalable platform for energy trading & grid services 

The Elli PowerCenter is not just a storage system: it also functions as a platform for energy trading and flexibility services. In the long term, it is set to become part of a large “Managed Battery Network” in which vehicle and storage systems are interconnected. 

5. Energy management & service expansion 

In parallel with its large-scale storage business, Elli already offers energy trading as a service today: in 2025, Elli will manage around 200 GWh for third parties and leverage its market access for power trading. The combination of charging infrastructure, storage, and energy trading enables sustainable business models and actively supports the energy transition.
