The company was responsible for the retrofit and upgrade of the complete steam turbine island and the associated balance of plant at the unit to match the new steam data following the installation of a gas turbine from another vendor.
Alstom replaced the high-pressure steam turbine in the unit with a high performance new module and upgraded the medium and low-pressure cylinders, the generator and the balance of plant.
This modernisation project, which began in 2009, has resulted in an increase of the unit’s capacity from 215MW to above 400MW and its efficiency from 36% to 57%, Alstom said.
Located near Budapest, the Dunamenti power plant has a total capacity of 1,736MW, with 6 x 215MW steam turbine units and two other combined-cycle and cogeneration units.
