Siemens Energy will build a turnkey natural gas-fired combined heat and power plant in Poland. The Polish energy utility PGE GiEK S.A. will invest in the Gorzów plant, which will have an electric capacity of 138 MW and a thermal capacity of 90 MW.
Thanks to the combined heat and power, the plant’s fuel efficiency rating will be 84%. Commissioning of the project is planned for early 2016, and the total order value for Siemens, including a long-term service agreement for the main components, is approximately €160 million.
Nitrogen-rich natural gas
The plant will be built in the city of Gorzów Wielkopolski, in western Poland. Within the scope of turnkey construction, Siemens will deliver two SGT-800 gas turbines, one SST-400 steam turbine, three 11-kilovolt (KV) generators and two heat recovery steam generators. In addition, the company was awarded a12 year maintenance agreement for the gas turbines. The plant will be fired with nitrogen-rich natural gas from gas reserves located in western Poland, which has a lower calorific value than conventional natural gas.
“We chose the Siemens solution because their plant offers a very high efficiency, so that it can generate electricity at a very affordable cost,” commented Jacek Kaczorowski, CEO of PGE GiEK. “The district heating makes the plant even more economical. Furthermore, we can use our local natural gas reserves to fire the turbines.”
“The SGT-800 industrial gas turbine is a proven machine which is also very flexible with regard to fuel. Together with the SST-400 steam turbine, it will generate reliable, environmentally friendly electricity and district heat in the Gorzów power plant,” added Grzegorz Nalezyty, head of the Power Generation Division at Siemens in Poland. “In total, Siemens has sold more than 227 SGT-800 gas turbines to date, which together represent operational experience of more than 2.5 million hours.”
The Gorzów power plant will replace a coal-fired block at the same location. The combined cycle power plant with heat extraction will be able to generate electricity in a much more efficient and environmentally friendly way. In comparison to the coal-fired power plant, the new plant will produce 95% less sulfur dioxide emissions, over 30% less nitrogen dioxide emissions and over 95% less particulate emissions.
