MAN Energy Solutions has been awarded the contract for two MST050 steam turbines, each with a gearbox, generator and auxiliary components. The steam turbines, with a total power output of 56 MW will be put into operation in a gas fired CHP power plant supplying the city of Leipzig with electricity and heat.
Today, the CHP plant generates up to 174 MW of electrical energy and 200 MW of thermal energy. The condensation heat is utilised in the citywide district heating network – thus reducing the CO2 emissions and increasing overall efficiency.
The further investment in the CHP plant is part of the public utilities' future concept: with the additional capacity, the city of Leipzig intents to reorganise its district heating supply, which is today partly dependent on the Lippendorf coal-fired power plant, by end of 2022.
The overall efficiency of the plant was further optimised by integrating the auxiliary cooling circuits in the district heating system. Furthermore, ATU (analytics telemetry unit) boxes by PrimeServ Assist, which are connected to the MAN CEON digital platform, will be integrated in the turbines. These provide the operator with 24 hour monitoring of the operation, and fast access to remote support from MAN.
Delivery and installation of the steam turbines in Leipzig is scheduled for the first quarter of 2021.
