1303  MW Lumut CCGT Power Plant in  Malaysia

Engineering, Construction, Commissioning & Operation Experience  

Abstract  

From 1994 to 1997  five Independent Power Producer projects, totaling 4070 MW, have been completed in Peninsula Malaysia, providing 38% of the total current generating capacity in the country. The 1303 MW Lumut Combined Cycle Gas Turbine (CCGT) Power Plant is the largest among Malaysian IPPs.

Lumut CCGT is not only the largest power plant in Malaysia, but also the largest CCGT in South-East Asia and the third largest IPP in the world.

After completion in 1997, each block will deliver 651.7 MW to TNB national grid and shall achieve an efficiency of above 52 % at local tropical ambient conditions.

Its design has been geared towards high efficiency, reliability and availability paying a great deal of attention to environmental considerations.

Lumut CCGT consists of two identical blocks, each comprising three dual fuel gas turbines, three heat recovery steam generators and one condensing steam turbine.

Engineering, Procurement and Construction contract for supply of 1303 MW Lumut CCGT was signed between Segari Energy Ventures Sdn. Bhd. (subsidiary of Malakoff Berhad) and ABB Power Generation Sdn. Bhd. in December 1993.

After having obtained all licenses and after signing power purchase, fuel supply and financing agreements, SEV released the instruction to proceed in April 1994.

The first CCGT block was handed over to the local O & M company, Teknik Janakuasa Sdn. Bhd., immediately after completion of  performance tests and trial run on 25 May 1996, only 25 months and 25 days from the project official commencement date. At the same day the block 1 started official commercial operation.

In 1993, SEV contracted Swiss consulting engineering company, IMTE AG, as technical advisor. IMTE AG was responsible for providing technical advisory and quality assurance services during contract negotiations, project engineering, factory inspections and tests phase as well as for supervision of erection, commissioning and taking over of equipment.

From 25 May 1996 until 31 August 1996, the first block accumulated 2’610 operational hours and has delivered 1’057’000’000 kWh to Malaysian national grid. It is fully available for any kind of operation as directed by national load dispatch center.

This paper contains interesting and most practical details gained during project planning and engineering, construction, erection and commissioning phase as well as during initial operation period of Lumut CCGT.
