Chemnitz Nord power station is a 167-megawatt (MW) coal-fired power station in Sachsen, Germany.

A new 150 MW gas plant is planned for operation in 2022. The two coal-fired units are planned for closure in 2023.

Background

Chemnitz Nord I consisted of three 25 MW units, first commissioned in 1961 and taken offline in 1997. Chemnitz Nord II was commissioned from 1986 to 1990. Unit 1 is fired by gas or oil, and units 2 and 3 by lignite coal dust.[1][2]

In August 2019 a contractor was commissioned to build two engine-powered combined heat and power (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.[3]

Construction work on the new CHP plant is planned for 2020, and operation in 2022.[4] In 2023, the two coal blocks of the Chemnitz CHP will go off line.[5]
