The energy company Vattenfall has announced its intention to build Germany’s largest power-to-heat system in Berlin, replacing one block of a hard-coal-fired power plant.
The 100-million euro investment comprises three hot water generators with a total capacity of 120 MWth, gas-fired peaker units, and investments in hydraulic and electrical infrastructure.
The system is expected to supply hot water to the Spandau district heat network following the 2019/2020 winter heating season, at which point it is planned that block C of the Reuter West power plant will be taken offline.
Vattenfall aims to exit coal-fired power and heat generation in Germany’s capital by 2030. In May of this year, the company switched the fuel source at the Klingenberg cogeneration plant, located in Berlin’s Lichtenberg district, from lignite to natural gas.
The power-to-heat project is taking place within the SINTEG program which aims to develop intelligent energy-supply solutions with a rising share of renewable power in the grid. The program is funded by the Federal Ministry for Economic Affairs and Energy.
