The new fuel-switch power plant in Stuttgart-Münster.
The Stuttgart-Münster plant sets an example for future projects, addressing the region’s need for stable power. EnBW CEO Georg Stamatelopoulos highlighted the importance of supportive policies, stating: “The power plants needed for the energy transition cannot be financed by the market alone. This is why the German government needs to create a framework of regulatory incentives for more investment as part of its programme for the first 100 days in power.”
Located at a site historically used for waste incineration, the Stuttgart-Münster facility is undergoing a major transformation. The existing combined heat and power (CHP) setup includes a coal-fired plant, a waste incineration unit, and three steam turbines. The upgraded site now features a new gas turbine plant with a gross electrical output of 114MW, supported by waste heat and hot water boilers.
The CHP plant supplies Stuttgart with 124MW of electrical energy and 370MW of thermal energy, meeting both steady and peak demand. By spring 2026, EnBW plans to phase out the coal-fired unit and fuel oil-fired gas turbines, aligning with Stuttgart’s target of achieving net-zero emissions by 2035.
The hydrogen-ready plant enhances the integration of renewable energy by offering the flexibility to balance grid fluctuations. This capability is vital for maintaining a stable power supply as renewable sources expand.
EnBW is also upgrading other facilities, converting coal-fired plants in Altbach/Deizisau and Heilbronn to hydrogen-ready gas-fired systems. These efforts are part of a broader plan to decarbonize its power generation portfolio, involving 1.5GW of capacity and a €1.6 billion ($1.8 billion) investment.
In 2024, EnBW announced a 100MW battery storage system for its Marbach site in Germany. With a capacity of 100 megawatt-hours, this facility will help stabilize the southern German electricity grid, focusing on grid support rather than direct household supply.
The Stuttgart-Münster project reflects EnBW’s commitment to sustainable energy solutions, contributing to regional grid stability and supporting Germany’s transition to cleaner power sources. By investing in hydrogen-ready infrastructure and modernizing its plants, EnBW aims to meet growing energy demands while reducing environmental impact.
