BRUSSELS, Belgium, May 29, 2001 — Construction is well underway at the Baglan Bay Power Station in South Wales, site of the world’s first GE H Systemâ„¢, GE Power Systems reported at Power-Gen Europe 2001.

Designed as a GE global showcase for advanced power generation technology, the Baglan Bay facility will start up in the summer of 2002.

The 480-megawatt Baglan Bay Power Station, being developed by GE on property leased from British Petroleum (BP) in Port Talbot, Wales, will supply electricity and steam to industrial and commercial facilities within the new Baglan Energy Park, with excess power bid into the U.K. grid. The Energy Park, jointly developed by BP, the Welsh Development Agency and the Neath Port Talbot County Borough Council, is one of the largest single areas of industrial development in the U.K.

The cornerstone of the GE H System is the 50-hertz MS9001H gas turbine which was shipped from GE’s Greenville, SC gas turbine manufacturing facility to Port Talbot in December of 2000. On-foundation installation of the 9H gas turbine will begin in July, with installation of the single-shaft combined-cycle unit’s steam turbine and generator to be completed during the summer.

Following startup at the site, the H System will undergo characterization testing through the summer of 2002, and a period of operation to validate its long-term performance and capabilities. The 9H system is designed to be the first gas turbine combined-cycle system in the world to break the 60% thermal efficiency, while meeting the most stringent environmental standards.

In addition to the H System, the Baglan Bay Power Station will include a 33-megawatt combined heat and power plant featuring a GE LM2500 aeroderivative gas turbine.

The LM2500 and a 2.3 megawatt diesel generator set are integrated with the H System to make the plant capable of blackstarts.

As of mid-May, the Baglan plant mechanical engineering was completed while electrical engineering is expected to be completed by early summer. The structural steel erection for the main control and electrical rooms for the 9H system were near completion, while the structural steel erection for the turbine building and the service and administration building had commenced. Construction of the 9H heat recovery steam generator also had started. The controls equipment for the project had been tested and was being prepared for shipment.

Overview of the H System

The world’s largest gas turbine, the 9H is 12 meters long, 5 meters in diameter, weighs 370 tons and is rated to produce 480 megawatts of electricity in combined-cycle operation, enough power for approximately 600,000 homes. The 9H technology was introduced in 1995, and the first 9H machine completed extensive testing in Greenville prior to being shipped to South Wales.

The H System combines the gas turbine, a steam turbine and a heat recovery steam generator into a seamless, combined-cycle system with each component optimized for the highest level of performance. The use of advanced materials and an innovative steam cooling system enables the H System to operate at the higher firing temperatures (1430 degrees C class) required for increased thermal efficiency.

The H System burns natural gas, a much cleaner fuel than other fossil fuel options. This technology, in combination with the steam cooling and high efficiency, is capable of achieving very low emissions. Although the new Baglan Bay plant is far larger than the oil-fired plant currently operating at the site, it will produce far lower emissions, reducing carbon dioxide emissions by 66%, nitrous oxide by 88% and sulphur dioxide by 99%.
