Siemens Energy has won a contract valued at €160m from PGE GiEK, a subsidiary of Polish utility PGE, to build a turnkey combined heat and power plant, replacing an old coal-fired power plant, in the city of Gorzow Wielkopolski.
According to the contract, Siemens will supply two SGT-800 gas turbines, a SST-400 steam turbine, three 11kV generators and two heat recovery steam generators for the plant, which will have a fuel efficiency rating of 84%.
The SGT-800 industrial gas turbine, which combines a reliable robust design with high efficiency and low emissions, offers flexibility in fuels, operation conditions, maintenance concepts, package solutions and ratings to meet current and future market needs, Siemens claims.
Siemens Poland Power Generation Division head Grzegorz Nalezyty said the SGT-800 industrial gas turbine is very flexible with regard to fuel and together with the SST-400 steam turbine, it will generate clean electricity and district heat at the Gorzow power plant.
"In total, Siemens has sold more than 227 SGT-800 gas turbines to date, which together represents operational experience of more than 2.5 million hours," said Nalezyty.
The scope of the contract also includes a 12-year long-term maintenance agreement for the main components at the plant, including gas turbines.
To be fuelled with nitrogen-rich natural gas, which has a lower calorific value than conventional forms, the Gorzow plant will have an electric capacity of 138MW and a thermal capacity of 90MW.
The new plant with district heat extraction will produce 95% less sulphur dioxide emissions, more than 30% less nitrogen dioxide emissions and more than 95% less particulate emissions.
In October 2013, PGE and PGNiG established a venture to develop the plant at PGE’s Gorzow CHP plant in the western part of the country.
PGNiG will supply natural gas from its domestic operations for the plant under a PLN3bn (€717.7m) power purchase agreement between the parties.
