At the beginning of 2020, EDF Renewables and malt producer Malteurop started operating two battery storage systems in Rostock and Heidenau. Each battery is designed to supply the respective production plant with 200 kW for at least one hour. The storage system can adapt the plant’s energy consumption to changing network conditions, thereby saving the company grid fees and making an important contribution to an effective energy transition in Germany.
The peak-shaving process: batteries are installed behind the meter, so directly integrated into Malteurop's power grid. When a load peak occurs, the power is supplied internally by the charged battery instead of being drawn from the overall power network. This flattens the load peak and since the electricity price is also calculated on the basis of the annual peak value, battery storage systems reduce grid fees and in consequence bottom line operating costs.
Battery storage is a game changer for the energy transition in Germany. In the context of both the planned grid expansion and boost of renewable energy sources, the aim is to make electricity available locally respectively regionally. Plus, storage solutions help to reduce load peaks so stabilize the overall network, ensuring a reliable power supply for all consumers at any given time.
