Rosenheim, Germany
The municipal utility Rosenheim provides heat and electricity using a range of
fuels: waste, natural gas, bio methane and waste wood are burned in a waste
heating plant, several CHP units and wood gasifiers.
The newly installed heat pumps are part of three so-called innovative CHP
systems (iKWK) which were completed in fall 2023. The LHPs are supplemented
of two electric boilers of 5,1 MWth as power-to-heat plants. Three gas engines
of totally 13,5 MWel complete the systems. The heat is stored in an existing
1.000 m3 tank. To be able to react flexibly to the actual availability of electricity,
grid requirements and the heat demand, the three heat generating
technologies are intelligently linked using the control and instrumentation
technology.
In the Real-World Laboratory the integration of the LHP in den district heating
network and the optimal application regarding grid friendliness and economic
efficiency is being investigated.
