Combined cycle power plant for Italian EP Produzione
Siemens Energy is building a combined cycle power plant on a turnkey basis in Ostiglia, Lombardy. The plant aims to reduce CO2 emissions in Italy and balance fluctuating feed-in from renewables to the grid. The utility EP Produzione S.p.A. is owner and operator of the plant.
The power plant is going to use HL-class gas turbine technology from Siemens Energy. This technology enables the flexible use of natural gas. The unit is designed to be fired with up to 30 percent hydrogen in addition to natural gas. The installed electrical output is 880 MW. Completion is scheduled for spring 2025.
An air-cooled condenser (AAC) cools the plant. In addition to the ACC, state of the art nitrogen oxide emission levels (below 10 mg/Nm3) ensure sustainability.
The power plant is designed as a multi-shaft unit with the gas and steam turbines each driving their own generator. Siemens Energy's scope of supply includes an SGT5-9000HL gas turbine, an SGen5-3000W gas turbine generator, an SST5-5000 steam turbine, an SGen5-1200A steam turbine generator, a heat-recovery steam generator, and the T3000 control system. The company will also provide long-term services for the plant’s core components.
