It is connected to Torino districtheating grid and can produce a thermal power of over 260MWt. Moncalieri is the repowering of an existing 141 MWconventional unit and it is able to work not only in combinedcycle configuration but also as a conventional cyclethanks to the piping connections to the existing firedsteam generator. During the commissioning phase thenew authomatic start-up sequence was successfullytested and applied to this plant. Due to transportationconstraints, the gas rurbine was assembled at site.Gas TurbineAE94.3A x 265 MW - 50 HzMain fuel: natural gasSteam TurbineExisting ST x 130 MW - 50 Hz85/24.5/3.68 bar - 536/536/221°CGeneratorGT unit: WY23Z-109LL - 300 MVA - 19 kV - 50 Hz - aircooledST unit: WX21Z-092RR - 170 MVA - 15.75 kV - 50 Hz - aircooledHeat Recovery Steam GeneratorThree pressure levels with RH, natural circulation, drumtype with integrated deareator.Cooling SystemSurface condenser.16152 Genova - Via N.
