Berlin to Harness Surplus Renewable Energy for District Heating with New 120-Megawatt Plant
Berlin, Germany – A significant step towards sustainable energy was announced today as Berliner Energie und Wärme (BEW), transmission system operator 50Hertz, and Stromnetz Berlin jointly initiated the construction of a 120-megawatt power-to-heat plant. This innovative facility, located at the Mitte combined heat and power (CHP) plant, is designed to convert surplus electricity generated by wind and solar power plants into district heating, dramatically improving Berlin’s energy efficiency and environmental footprint.
The plant is projected to be fully operational by the end of 2028. The state-owned BEW will oversee the construction, while 50Hertz will be the primary financier, contributing up to 75 million euros to the project. This collaborative effort underscores a concerted drive towards integrating renewable energy sources into the city’s heating infrastructure.
Improving Congestion Management and Reducing Emissions
One of the key functions of the new facility will be to enhance congestion management for 50Hertz. Currently, when renewable energy production, particularly in eastern Germany, exceeds local consumption capacity, wind or solar power plants may be curtailed. The new power-to-heat plant offers a solution by absorbing this excess electricity and channeling it into Berlin’s district heating network.
This approach offers multiple benefits. Firstly, it reduces the reliance on fossil fuels, thereby significantly cutting CO₂ emissions. Secondly, it ensures that customers receive 100 percent renewable energy for their heating needs. Furthermore, district heating remains essential even during warmer months, as it is used for purposes such as heating water, ensuring continuous demand for the plant’s output.
Significant CO₂ Savings and Household Supply
BEW has highlighted the substantial environmental impact of the new plant. “In the first five years of operation alone, the plant will save approximately 76,000 tons of CO₂ annually thanks to reduced gas consumption at the combined heat and power plant in Mitte and increased use of renewable energy,” BEW announced. This reduction in greenhouse gas emissions is a crucial contribution to Berlin’s climate goals.
The long-term benefits are even more impressive. “In the long term, when fully operational, the plant will be able to supply district heating to over 30,000 average households in the winter and provide sufficient hot water for around 360,000 households in the summer,” the statement added. This capacity demonstrates the plant’s potential to meet a significant portion of Berlin’s heating demands with clean energy.
The project represents a forward-thinking investment in Berlin’s energy future, aiming to create a more resilient, sustainable, and environmentally friendly urban environment. By transforming renewable electricity into a reliable source of heat, Berlin is setting a precedent for other major cities looking to decarbonize their energy systems.
