ArcelorMittal Germany and EDF Power Solutions Germany have signed an agreement to develop a large-scale battery energy storage system at the Bremen steelworks, marking another step in the steelmaker’s broader strategy to improve energy efficiency and reduce carbon emissions.
The planned facility will have a power output of 25 megawatts and a storage capacity of 50 megawatt-hours. According to the companies, this will make it one of the largest battery storage projects currently planned in northern Germany.
Under the agreement, EDF Power Solutions Germany will manage the full project scope, including technical design, installation, maintenance, and service operations. The cooperation includes a 10-year service contract.
Focus on electricity optimization and grid stability
The battery system is designed to optimize electricity consumption at the steelworks and reduce pressure on the power grid. By charging and discharging during predefined periods, the system will help smooth electricity demand and avoid costly peak loads during steel production.
Steelmaking facilities require continuous operation and cannot easily pause production during periods of high electricity prices. The battery installation is expected to provide additional operational flexibility while helping lower energy procurement costs.
Additional revenues through electricity markets
Beyond internal energy management, the battery system will also participate in electricity markets. The storage facility is expected to generate additional revenues through power trading and grid balancing activities.
Rainer Böse, CEO of ArcelorMittal Germany, stated that the project represents another important step toward lowering carbon emissions while contributing to grid stability through continuous electricity consumption management.
