Tavazzano e Montanaso power plant, with a net installed capacity of 1,140 MW, is located in the province of Lodi (Lombardia region). Thanks to the use of natural gas as unique fuel (since 2010), the power plant emissions significantly decreased than previous years, both in absolute terms (tons per year) and as concentrations. Previously equipped to burn both fuel oil and natural gas, at the beginning of 2000s the power plant was partially converted into a gas-combined cycle with two CCGT modules (one module composed of one gas turbine and one steam turbine and the other one composed of two gas turbine and one steam turbine).
Another 320 MW unit (that would use only natural gas), has been mothballed since April 2013.
