Siemens H-class turbines to power combined cycle plant in Poland

Published on: 

Siemens has bagged an order in Central Europe for the first time outside of Germany for turn-key erection of a combined cycle power plant to be equipped with the innovative Siemens H-Class gas turbine. PKN Orlen, Eastern Europe's mineral oil company is the customer for the 596 Megawatt (MWe) plant in Płock. Located around 100 kilometers northwest of the capital city of Warsaw, the plant is designed to be very flexible and can feed electricity into the national power grid. It can also supply the facility with electricity and process steam, for complex refine and petrochemical production in Płock. Commissioning of the plant is scheduled for the end of 2017.

Siemens is likely to build the single-shaft plant in Płock turnkey, and supply the main components – an SGT5-8000H gas turbine, the heat recovery steam generator, an SST5-5000 steam turbine with an SCon-2000PF condenser, an SGen5-3000W generator, the electrical systems and the SPPA-T3000 I&C system. Siemens will also be responsible for plant maintenance and service for a period of around 12 years.


Since 2003, the Polish economy has grown significantly faster than average growth in other EU countries. Power demand in the country has increased from 140,590 GWh to 157,980 GWh, not least due to a rise in industrial production. Rainer Hauenschild, head of Energy Solutions in the, Siemens division Power and Gas said the order for the Płock combined cycle plant is the first order for the company’s proven H-Class power plant technology in Central Europe outside of Germany. “We will be supplying a competitive solution that is tailored exactly to the needs of our customer,” he said.

With this order, 44 of the H-class gas turbines have been sold worldwide to date. Thirteen of these machines are currently in successful commercial operation with a high degree of starting reliability and availability.
