GE is to modernize one of three turbine-gensets at a Polish district heating plant, the company announced this week.

The 275 MW Veolia Energia Poznań ZEC SA district heating plant in the city of Poznań features one 65 MW genset and two 105 MW gensets. GE aims to increase the output of unit 3 by up to 6 MW, as well as improving the efficiency of the steam turbine by up to 6%.  

In addition, to improve the turbine’s operational flexibility, during periods of no power demand the operator will be able to disconnect the low-pressure (LP) part of the steam turbine while it is in full district heating mode, allowing the operator to use thermal power for the preheating of district-heating water only, GE said.

Work is expected to start in May 2017, and commissioning of the upgraded equipment is expected in August 2017.

GE can now service non-GE supplied steam turbine equipment after its acquisition of Alstom Power’s thermal services business in November 2015. The turbines at the Poznań plant were made by Poland’s Zamech, which was previously acquired by Alstom.
