Siemens Energy will build a turnkey combined heat and power plant in Poland. The Gorzów plant will have an electric capacity of 138 megawatts (MW) and a thermal capacity of 90 MW.
Thanks to combined heat and power, the plant’s fuel efficiency rating will be 84%. Commissioning is planned for early 2016. The order value for Siemens, including a long-term service agreement for the main components, is about €160m.
The plant will be built in western Poland in the city of Gorzów Wielkopolski. 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, Siemens was awarded a long-term 12 years maintenance agreement for the gas turbines. The Gorzów plant will be fired with nitrogen-rich natural gas from gas reserves located in western Poland. This type of gas 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,” said 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,” said Grzegorz Nalezyty, head of the Power Generation Division at Siemens Sp. z o.o. 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 currently used coal-fired block at the same location. The combined cycle power plant with district heat extraction will be able to generate electricity in a much more efficient and environmentally friendly manner. Compared to the old coal-fired power plant, the new plant will produce 95% less sulfur dioxide emissions, more than 30% less nitrogen dioxide emissions and more than 95% less particulate emissions.
Highly efficient combined cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2012, revenue from the Portfolio totaled about €33bn, making Siemens one of the world’s largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by more than 330 million tonnes, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.
