Enipoweris the electric power operator with an important network of petrochemicalsplants spread across Italy providing, ideal locations fornew capacity…and with this contract planning 8 combined cyclesfor installation in four industrial areas owned by the group,will deliver a total of about 3,850 MW. The plant, the first of four,rated 1,050 MW featuring two natural gas unit rated about 800MW and a 250 MW syngas unit. One of the key factor of AnsaldoEnergia’ success was the maintenance and assistance proposalformulated using innovative criteria. Maintenance and assistancealone are worth roughly a quarter of the entire contract amount.The plant also highlights the growing trend in power generationmachinery demand for high base load plant.Gas Turbine1 x AE94.2K x 167 MW, 2 x AE94.3A x 258 MW - 50 HzMain fuel: syngas (AE94.2K), natural gas (AE94.3A).Steam TurbineST for 2x(1+1) CC: MT15 x 131.5 MW - 50 Hz117/30.8/4.8 bar - 559/559/234°C;ST for (1+1) CC: 1 x 88 MW - 50 Hz95/29/6.5 bar - 510/510/260 °CGeneratorGT units: WY23Z-109LL - 300 MVA - 19 kV - 50 Hz- air cooledST units: WX21Z-092LLT - 170 MVA - 15.75 kV - 50 Hz- air cooledGT Syngas unit: WY21Z-092LLT - 200 MVA - 15.75 kV- 50 Hz - air cooledHeat Recovery Steam GeneratorOut of Ansaldo Energia Scope of supply.Cooling SystemOut of Ansaldo Energia Scope of supply.16152 Genova - Via N.
