The agreement covers six GE Frame 7FA gas turbines installed for the repowering of Manzanillo Thermoelectric, a thermo power generation project undertaken by the Mexican government.
The turbines were recently installed at the Manzanillo site and the first three units are scheduled to be commissioned by the end of 2011.
The repowering project will add 900MW capacity, bringing the total site capacity to 1,500MW.
The new gas turbines are replacing two conventional boilers currently operating on fuel oil at the power plant.
GE said that the repowering project is expected to improve plant efficiency by 50% and reduce carbon dioxide emissions by 2,000 tons per year.
