Alstom completed modernisation of unit 8 of the Dunamenti gas-fired power plant owned by GDF SUEZ. The modernisation project awarded to Alstom in 2008 included the retrofit and upgrade of the complete steam turbine island and the associated balance of plant at unit 8 of the plant to match the new steam data following the installation of a gas turbine from another vendor. The project started in April 2009 and has been successfully completed with the commissioning of the retrofitted unit 8 in July this year. It has contributed to the increased output of unit 8 from 215 MW to above 400 MW and the jump in efficiency by more than 20% - from 36% to 57%.
Dunamenti is located near Budapest and is one of the country’s biggest power plants with 6 x 215 MW steam turbine units and two other combined cycle and cogeneration units. The plant has a total capacity of 1736 MW. The retrofit of unit 8 labelled ‘G3’ was part of a bigger rehabilitation programme undertaken by GDF SUEZ to reduce the environmental impacts of their plant.
