The project comprised the conversion of two General Electric 6FA gas turbines operating in open cycle mode to combined cycle. This involved the installation of two heat recovery steam generating boilers which utilize the waste heat from the gas turbine to raise steam. The steam is used to generate electricity using an associated steam turbine of 96 MW capacity with over-firing taking the gross capacity to 238 MW. The project pioneered the UN methodology for the application of CER carbon credits to combined cycle conversion. The project was registered at UNCCC in 2008 and the CER carbon credits were sold under a forward contract to KFW, CAF and the Kingdom of Spain.
