Bad Reichenhall (GER)

Background

“Green” heat is at the heart of Stadtwerke Bad Reichenhall’s innovative combined heat and power system. Primarily used for regional heat supply, this “iCHP” system flexibly combines several key technologies centered on two highly efficient Jenbacher combined heat and power (CHP) plants from INNIO Group.

These heat and electricity producers are supplemented by two large groundwater heat pumps, which use renewable environmental heat and green electricity to generate green heat. Two power-to-heat systems convert surplus green electricity into heat, and a photovoltaic system is used for the iCHP system’s own electricity requirements.

In addition, three large heat accumulators enable flexible use of the individual heat generators, depending on heat consumption.

Solution

Intelligent solutions are needed to manage such highly complex integrated systems. For optimal use, they must have common control and regulation technology.

For this reason, Stadtwerke Bad Reichenhall also chose INNIO Group’s myPlant Optimization, a digital all-in-one energy management solution from the original manufacturer. This software combines INNIO Group’s many years of Jenbacher plant experience with an optimized heat and storage schedule. It supports the municipal utility in heat generation in line with demand while providing it in a cost-optimized and sustainable way.

For supply stability, the overall system reacts flexibly to fluctuations in the two energy sectors of heat and power.
