On March 9, due to the global demand for electric vehicles falling short of expectations, Volkswagen, Europe's largest automaker, is expanding its battery business from the electric vehicle sector to large-scale energy storage and energy trading. On Monday, Volkswagen launched its first large-scale energy storage facility in Salzgitter, Germany. The project, managed by Volkswagen's energy subsidiary Elli, can provide approximately two hours of electricity for up to 20,000 households and is directly connected to the grid for trading on the European Power Exchange EPEX SPOT. The batteries used in the facility are sourced from Volkswagen's internal PowerCo division. As battery suppliers reduce prices and the growth of electric vehicles slows down, Volkswagen is seeking new sources of battery revenue. Previously, Volkswagen set a goal to have the capacity to supply batteries for approximately 3 million electric vehicles annually by 2030. With the rapid proliferation of data centers and the integration of renewable energy power plants into the grid, the demand for energy storage is rising swiftly.
