A battery storage system is to make the ArcelorMittal steelworks in Bremen more flexible. "EDF power solutions Deutschland" is taking over the construction and operation.
Steel manufacturer Arcelormittal and energy provider EDF power solutions Deutschland have signed a contract for a battery storage facility at the steel site in Bremen. The facility will have an output of 25 MW and a storage capacity of 50,000 kWh.
The planned battery storage system is primarily intended to support load management. According to a statement from Arcelormittal, the plant cannot simply switch off its systems during ongoing production. The storage system will therefore charge and discharge automatically in defined time windows. In this way, Arcelormittal aims to smooth out the demand for electricity during periods of high grid load and avoid peak loads.
Arcelormittal is one of the largest steel manufacturers in Germany and operates several production sites in the country. According to its own figures, the company produces around 8 million tons of crude steel per year and employs around 9,400 people in Germany. Its customers include the automotive, construction and packaging industries as well as manufacturers of household goods. Arcelormittal operates an integrated flat steel plant in Bremen.
EDF Power Solutions Deutschland develops, builds and operates its own wind energy and photovoltaic projects. The company also offers battery storage solutions and green power generation for hydrogen projects. The German company is part of the international EDF Power Solutions Group, which is active in more than 25 countries. According to EDF, it has been working in Germany for over 20 years with teams in Berlin, Stuttgart and Hamburg.
More flexibility in load management
A battery storage system can combine several tasks for energy-intensive industrial companies. It provides short-term power, absorbs electricity and thus creates flexibility in operation. Arcelormittal also wants to use the system flexibly on the electricity market. The company has two goals: To generate electricity revenue and reduce procurement costs.
According to Arcelormittal, the storage capacity of a fully charged battery covers the electricity consumption of a one to two-person household with an annual consumption of 2,500 kWh for around 20 years. The calculation does not take recharging into account.
According to the press release, EDF Power Solutions Deutschland is responsible for the technical design, installation, service and maintenance as part of a ten-year service contract. The press release does not contain any information on investment costs or the planned commissioning date.
The Bremen site is one of Arcelormittal's four major production sites in Germany. In addition to the integrated flat steel plant in Bremen with the coking plant in Bottrop, the company operates another flat steel plant in Eisenhüttenstadt and long steel plants in Hamburg and Duisburg. According to the company, there are also other production, sales and trading locations.
