The TURBIGO Repowering Combined Cycle Power Plant is located in the North of Italy, 45 km North from the city of Milano. 
EDIPOWER, now Iren SpA, one of the biggest players in the Italian power generation market, signed a turnkey Engineering, Procurement & Construction (EPC) contract with a JV between Siemens and Consorzio T800 (a consortium between Tecnimont and Techint) for the construction of 850 MW repowering to be installed in the existing power plant in year 2005. 
The project is based on no. 2 gas turbines burning natural gas, each of them associated with a three-pressure level RH horizontal, natural circulation HRSGs with duct burning system, feeding one full condensing modified and overhauled steam turbine generator. 
Due to the restrictions imposed by the existing installation and by the location of the steam turbine and of the switchyard area, the space and layout of the plant have been adequately optimized thus conferring a specific characteristic.

The power plant has been conceived in compliance with the best practices in sustainability and environmental responsibility. The activities were executed in compliance with the rules of ISO 14001 and EMAS.
