Battery storage supports the steelmaker’s climate targets

The battery storage facility at the steelworks in Bremen will play a key role in the plant’s load management in future. It helps to effectively smooth out electricity demand during periods of high grid load.

ArcelorMittal and EDF power solutions Deutschland sign contract for 25 MW battery storage facility in Bremen. The flexible solution helps stabilise the electricity grid and reduces energy costs.

ArcelorMittal, one of the world’s largest steel producers, and EDF power solutions Deutschland , a leading provider of battery storage solutions, have signed a contract for the operation of a large-scale battery storage facility at ArcelorMittal’s Bremen site. The planned storage facility has a 25-megawatt output and a 50-megawatt-hour capacity. To put this into perspective: a battery of this size could supply a small household with an annual consumption of 2,500 kWh for around 20 years – without a single recharge.

Greater efficiency, fewer peak loads

The battery storage system will play a central role in the plant’s load management in future. It specifically helps to smooth out electricity demand during periods of high grid load. This reduces the strain on the electricity grid whilst simultaneously lowering the company’s energy costs. As plant equipment cannot simply be switched off during ongoing production, the battery storage system provides additional flexibility: it charges and discharges automatically within defined time slots, thereby preventing peak loads. Furthermore, the storage system is deployed flexibly on the electricity market to generate revenue from electricity sales or reduce procurement costs.
Under a 10-year service contract, EDF power solutions Deutschland is responsible for every stage of the process, from technical design and installation to service and maintenance.

Contribution to the energy transition

“The battery storage facility at the Bremen site will be one of the largest in northern Germany. As the plant can draw electricity around the clock, the storage facility contributes significantly to grid stability. In this way, we are making an active contribution to climate protection. Furthermore, the project is a further step towards reducing CO₂ emissions even more in the future,” explains Rainer Böse, CEO of ArcelorMittal Germany.
