GE, together with the EPC contractor Polimex Mostostal, is building the two gas-fired units on a turnkey basis. Equipped with two 9HA.01 gas turbines and two STF-D650 steam turbines, the two CCGTs will provide up to 1.4 gigawatt (GW) of flexible power at Dolna Odra – enough to meet the electricity demand of about 1 million Polish households.
With the commissioning of the new units in 2023, PGE hopes to reduce CO2 emissions at Dolna Odra by about 2-3 million tonnes per year. The coal-fired plant currently consists of eight units, two with 220 MW and six with 232 MW. Units 5-8 have already been retrofitted with a Lurgi-built flue gas desulfurization plant.
Capacity contract
The Dolna Orda power plant, situated near the town of Gryfino, plays a critical role for the Polish National Grid as it is the only system-relevant producer for the country’s industrialized north-western region. The plant expansion with two flexible CCGTs has been awarded a 17-year contract in the main power market auction, with electricity supply due to start in 2024.
“PGE's investment in Dolna Odra Power Plant based on gas fuel is our contribution to preparing the Polish power system for further development of renewable energy, in particular wind energy," said Wojciech Dąbrowski, President of PGE’s management board.
By retrofitting the coal power plant, first commissioned in 1974, with two modern gas power units, the operator aims to enhance the plant’s operational flexibility and reduce overall emissions. The cleaner-burning units also help prolong the life-time of the system critical power unit in West Pomerania.
