8 July 2002 – The San Roque power plant in Cadiz, Spain was officially opened 3rd July, after a successful test run period. The Alstom built plant is the first in Spain to enter commercial operation utilizing the KA26-1 standardized Alstom combined-cycle plant package.
The opening ceremony, attended by Mr. R. Rato, the Spanish Minister of Economy, Mr. Antonio Brufau, President of Grupo Gas Natural and Mr. Manuel Pizarro, President of Endesa and hosted by Grupo Gas Natural and Endesa, the owners of the plant.
The San Roque power plant (2 x 400 MW) was built by Alstom based on the standardised combined-cycle reference plant concept. Alstom supplied four single-shaft power trains each composed of one GT26 gas turbine, an associated heat recovery steam generator, a steam turbine and an electrical generator as well as the overall power plant control system and balance of plant. As a turnkey supplier, Alstom was also responsible for the engineering, procurement and construction of the plant and will also operate and maintain the plant for a period of seven years.
Currently, Alstom is building more than 2200 MW of combined-cycle power plants in Spain. Most of these plants also utilise GT26 sequential combustion gas turbine technology.
Until the last decade, Spain has not used gas for power generation to any great extent. This is now changing with gas generation forecasted to rise to 15 per cent as the country strives for a clean assessable alternative to coal and oil. Grupo Gas Natural and Endesa are leaders in the use of gas fuel for new power generation and the first companies in Spain to operate combined-cycle power plants.
