Onsite genset producer INNIO provided four Waukesha gas engines for a German combined heat & power (CHP) plant which was modernized and commissioned into operation recently.
INNIO’s authorized partner, S&L Energie-Projekte GmbH, provided four packages of INNIO’s Waukesha VHP 9394GSI rich-burn gas engines for the Stadtwerke Lutherstadt Wittenberg GmbH CHP plant.
Situated 60 KM (37 miles) north of Leipzig and 90 KM (56 miles) southwest of Berlin, Stadtwerke Lutherstadt Wittenberg was founded in 1991 with a small CHP plant and just a few district heating customers. Today, Stadtwerke Lutherstadt Wittenberg is a modern combination utility supplying clean power 365 days a year to around 41,000 households and environmentally friendly heat to 21,000 homes.
“In comparison with the previous combined heat and power (CHP) plant, the overall efficiency of the new CHP plant is significantly higher. Our testing shows that the modernized district heating plant achieves a significant overall efficiency that is well above the guaranteed zero tolerance value of 95%, and the emission values are well below the legal national requirements,” said Hans-Joachim Herrmann, executive director, Stadtwerke Lutherstadt Wittenberg GmbH. “S&L completed the project on time and also provided a solution of INNIO’s Waukesha gas engines that not only met, but exceeded our performance and emissions requirements.”
The 16-cylinder Waukesha VHP 9394GSI can produce 2,200 brake horsepower or close to 1,700 kW (1.7 MW) at 1,200 RPM, according to the specs. The engine efficiency can help cut down on emissions, important as Germany is trying to reduce greenhouse gases 40 percent by 2020.
Emissions of the new plant are about 80 percent below future national requirements. INNIO’s rich-burn engines can meet these requirements by using a three-way catalyst.
INNIO was separated out of GE when investors Advent International acquired the Jenbacher and Waukesha engine lines last year. The carve-out was completed and rebranded as INNIO four months ago.
Last month, INNIO announced that it will supply six Jenbacher natural gas engines for a wide-ranging Finnish microgrid project including solar power, energy storage and onsite gensets.
INNIO is headquartered in Tyrol, in western Austria. The Waukesha engine brand remains rooted in Wisconsin, where the original company was founded more than 100 years ago.
