GE Power Systems has received contracts from Spanish energy producer Iberdrola Generacion of Madrid to provide gas turbine combined-cycle systems for two power projects in Spain that will add more than 1,600 megawatts to the country’s electricity grid.
The projects – CCC Arcos de la Frontera Grupo III in Cadiz, Spain and the Escombreras project in Murcia, Spain – will be the first to feature GE MS9001FB (Frame 9FB) gas turbines.
Each of the Iberdrola projects will be based on a GE 209FB combined-cycle system comprised of two Frame 9FB gas turbine-generators and one steam turbine-generator. The projects will also feature GE D11 steam turbines equipped with new 48-inch last-stage buckets, and GE’s 330H generators.
‘We are very pleased that Iberdrola, one of Europe’s leading energy companies, has selected us for these projects, which represent several significant milestones for our combined-cycle technology,’ said Mark Little, vice president, GE Power Systems- Energy Products.
According to GE, the Arcos III project will produce approximately 810 megawatts when it enters service, while the Escombreras project will produce 815 megawatts. Both plants will use natural gas and will operate at a combined-cycle thermal efficiency of more than 58%, placing them among the world’s more efficient combined-cycle power stations.
The GE D11 steam turbines for the two projects feature 48-inch last-stage buckets, the largest steel, full-speed (3000 rpm) last-stage buckets in terms of annulus area. The new buckets, developed by GE and Toshiba, are designed for improved plant efficiency and lower cost of producing electricity.
The GE 330H generators for the two Spanish projects are rated at 330/360 MVA. GE also will supply heat recovery steam generators, a distributed control system, training and technical assistance.
The gas turbines will be manufactured at GE’s Greenville, South Carolina facility and the steam turbine and generators will be built at GE’s Schenectady, New York plant.
