GE Frame 9FB Gas Turbines Surpass 8,000 Hours At Iberdrola’s Arcos III Plant


Spanish Project Is Global Launch Site for the Technology

ATLANTA, GA - January, 2008 : – A GE 209FB combined-cycle system has surpassed 8,000 operating hours at CCC Arcos de la Frontera Grupo III (Arcos III) in Cadiz, Spain, the commercial launch site for GE’s 50-hertz, 9FB gas turbine technology. In commercial operation since March 2006, the Arcos III plant is owned by Spanish energy producer Iberdrola Generacion S.A. and is generating approximately 810 megawatts of power for the Spanish electricity grid. The 8,000-hour mark is considered an industry milestone.

The 209FB configuration at Arcos III consists of two Frame 9FB gas turbine-generators, one GE 209D steam turbine-generator and two heat recovery steam generators. Using natural gas as its fuel, Arcos III is operating at a combined-cycle efficiency of around 58 percent, placing it among the world’s most efficient combined-cycle power stations.

Iberdrola also selected GE 9FB gas turbines for the Escombreras combined-cycle plant, which has been in operation since October of 2006 and is the world’s second installation of the technology, as well as for Castellón 4 combined cycle plant, which is currently undergoing commissioning.

“Our 9FB technology was designed to help our customers meet their growing requirements for reliable and cost-effective power,” said Ricardo Cordoba, president, Western Europe and North Africa for GE Energy. “We are very pleased that Iberdrola, one of the world’s leading energy companies, is utilizing this technology to help meet Spain’s electricity needs.”

The Frame 9FB is among the world’s most advanced, air-cooled, 50-hertz gas turbines and is the latest evolutionary step in GE’s F technology, which has surpassed 22 million hours of commercial service worldwide. There are currently 39 GE Frame 9FB gas turbines operating or committed for projects worldwide, including 16 for the highly competitive Iberian market.

Addressing the growing need for cleaner power, the Frame 9FB gas turbines are equipped with GE’s advanced, Dry Low NOx 2+ combustion systems, which limit NOx emissions to 25 parts per million or less. The machines also feature GE’s advanced SPEEDTRONIC™ Mark VI control systems.

The GE 209D steam turbine at Arcos III features state-of-the-art, 48-inch last-stage buckets, the industry’s largest steel, full-speed (3000 rpm) last-stage buckets in terms of annulus area. Developed by GE and Toshiba, the new buckets are designed for improved plant efficiency and lower cost of producing electricity.
