WINGAS cooperates with Bielefeld municipal utilities with micro-CHP plant field test

For the environment: WINGAS cooperates with Bielefeld municipal utilities on a field test for a micro-CHP plant

Bielefeld. For this very purpose, a micro-CHP plant with a Stirling engine was installed in the basement of a Bielefeld residential building of BGW (Bielefelder Gemeinnützige Wohnungsgesellschaft mbH), and in addition to heat and hot water, it will now also generate electricity. The cooperation partners, Stadtwerke Bielefeld, WINGAS, the heating specialists, Baxi Innotech from Hamburg, and BGW, have now presented their new system.

WINGAS is on board as a partner because of its experience in micro-CHP plant research and its cooperation with municipal utility companies across the whole of Germany. "Energy use has to become more efficient if we are going to achieve the climate protection objectives targeted by the Federal Government," explained WINGAS Managing Director Sales, Dr. Ludwig Möhring.

Stadtwerke Bielefeld considers combined heat and power generation to be one of the most efficient solutions in making a fundamental change in climate and energy policy. "Together with WINGAS, our natural gas supplier of many years, we want to gain experience with the near-series ready Baxi system with an end customer," explained Friedhelm Rieke, Managing Director of Stadtwerke Bielefeld.

WINGAS has a long-standing successful partnership with the Bielefeld municipal utilities. "Back when we set up the natural gas conditioning plant in Bielefeld's Ubbedissen district we already proved that we bring innovations to the market," emphasizes Detlef Mirsch, Head of Technical Services at WINGAS. "This must also be our claim to fame for our micro-CHP project."

The Stirling engine replaces the existing condensing boiler and works heat-led modulating. The micro-CHP plant's electronics regulate the heat capacity to constantly operate the Stirling engine in as efficient and reliable a range as possible, and to provide the required temperatures for heating and hot water supply at the right time.
