A CHP plant in Germany has been modernized to significantly reduce its emissions.

The plant southwest of Berlin is operated by utility Stadtwerke Lutherstadt Wittenberg and supplies electricity to around 41,000 homes and heat to 21,000.

The modernization was carried out by INNIO, which utilized four sets of Waukesha gas engines supplied by its partner S&L Energie-Projekte.

“In comparison with the previous CHP plant, the overall efficiency of the new plant is significantly higher,” said Hans-Joachim Herrmann, executive director of Stadtwerke Lutherstadt Wittenberg.

“Our testing shows that the modernized plant achieves a significant overall efficiency that is well above the guaranteed zero tolerance value of 95 per cent and the emission values are well below the legal national requirements and emissions of the new plant are about 80 per cent below future national requirements”.

He explained: “Through the modernized district heating plant, we are doing our part to help meet Germany’s goals of decarbonizing the energy system in Germany and meeting a minimum of 80 per cent CO2 reduction by 2050.”

S&L – which is headquartered in Spelle in Germany’s Emsland region and also serves the Netherlands, Belgium and Italy – supplied the generator for the genset package, performed the grid code certification and provided the balance of plant for the engines.

INNIO is a solutions provider of gas engines, power equipment, a digital platform and related services for power generation and gas compression at or near the point of use. It is headquartered in Jenbach, Austria, and also has operations in Ontario, Canada, and Wisconsin, US.
