New Plant
GT11N2 Gas Turbine - Key references
60 units in commercial operation or under construction, with over 1’200’000 fired hours
> Termobarranquilla (Columbia) - 750 MW
This natural gas-fired combined cycle power plant, located near Barranquilla on Columbia’s Atlantic coast, is one of the largest IPP projects in Latin America. The power plant consists of two power blocks: one block based on three GT11N2, and one steam turbine and two blocks based on two GT11N2 and a second steam turbine.
This power plant is one of the cleanest in South America. The first two units are currently the leaders of the GT11N2 fleet, with more than 70,000 fired hours each.
> Bao Shan (China) - 150 MW
Bao Steel Corporation of China installed a GT11N2 unit for operation on LBTU blast furnace gas, a by-product of the steel-making process. Built in co-operation with Kawasaki Heavy industries, this combined cycle facility aligns gas turbine, gas compressor, steam turbine and turbogenerators on a single shaft. The gas turbine went in operation in the first quarter of 1997. The plant is designed to provide up to 150 MW of electrical power and up to 180 tons/hr of steam to the steel mill, while burning blast furnace gas with a heating value of 2,200 kJ/kg.
> Valle de Mexico (Mexico) - 550 MW
The plant was the first combined cycle plant in Mexico whose design allows for operation in pure combined cycle or hybrid mode.
Alstom supplied three GT11N2 gas turbines with TOPAIR turbogenerators, three heat recovery steam generators (HRSG) and the associated auxiliary equipment, engineering, the electrical and control system and a high voltage switchyard.
Alstom was responsible for site preparation, civil works, erection and commissioning. Alstom also originally supplied the existing steam turbine to Valle de Mexico.
