Projects will include 12 engines, they produce 150 MW of power and 130 MW of thermal output
The city of Chemnitz and the energy service provider Eins Energie in Sachsen will set up two new CHP plants. The two plants, MHKW Nord and Altchemnitz, will be operated with seven and five MAN gas engines of type 20V35/44G TS respectively, each with an electrical output of 12.6 MW. The new CHP plants will supply the city with just under 150 MW of electricity and over 130 MW of thermal output.
Vestas Aircoil a/s and MAN Energy Solutions have developed the charge air cooler family for the 35/44 engine series.
With this project, the CO2 output reduced to around 60% – this corresponds to the emissions of around 260 000 passenger cars.
The MAN 20V35/44G TS engines are among the most efficient engines worldwide. The MHKW Nord plant is being constructed on the site of the previous lignite-powered Nord I power plant, which was demolished in 2004. The photovoltaic system that had been operated on the site since then has already been transferred to a new location. The second CHP plant will supplement the heating boiler system at the Altchemnitz heating plant, which is also powered by natural gas and was upgraded in July.
The new power plants are set to commence operations in 2022.
