SembCorp, the Singapore independent power producer, yesterday opened its new 815 MW cogeneration plant at Pulau Sakra.

The plant, powered by GE Power Systems’ Frame 9FA gas turbines, will be Singapore’s largest co-generation plant. It will be burning green fuel – natural gas imported by SembGas – to produce electricity for Jurong Island and the Singapore Electricity Pool and will also generate steam for SempCorp Utilities and Terminals (SUT) and for the chemical companies operating on the Island.

The advanced F technology Frame 9FA gas turbines are equipped with low NOx combustion systems, the turbines are environmentally friendly, with a target NOx level of 25 ppm or less. More than 255 GE F technology gas turbines operate in power plants around the world, clocking in excess of 4 million hours of operation.

The gas turbines are also equipped with features to burn distillate fuel, as a backup for the primary natural gas fuel, and are provided with a water injection system for NOx reduction while operating with the back-up fuel.

Gas turbine packages are designed specifically in modular assemblies to ensure easy site assembly and installation. A multi-shaft combined cycle plant configuration adds to high operational flexibility.

F.L. Leow, regional executive of GE’s Energy Products division said,”The efficient, reliable and environmentally friendly design of this plant will help the customer to be positioned strongly in the coming competitive power market scenario in Singapore, during its operation phase.”

Long-term and reliable operation of the power plant will be facilitated by a Contractual Services agreement between GE and SembCorp Cogen. Under the six-year agreement, GEU will support plant operation with advanced monitoring and maintenance management systems and a range of other services including repairs, spares and technical advisory. This service support includes planned as well as unplanned maintenance and repair of the gas turbines, as well as around-the-clock support for emergencies.

Construction of the SembCorp plant began in August 1999, with the gas turbines arriving in May and June 2000. In just five months, the plant reached its commissioning stage, and the first firing of the two gas turbines occurred before the close of the year in November and December of 2000. By August of this year, the trial run of the plant was successfully carried out and a provisional acceptance certificate was awarded. As of now, the plant has clocked more than 7000 operating hours.

SembCogen is a joint venture between SembCorp Engineering, Tractebel and EDB Investments.
