Upon its commercial operation in July 2001, the Operation and Maintenance of the plant is vested with Fortum O & M Thailand Ltd., a subsidiary of Fortum Group. In December 2002, Fortum Group handed over full ownership of LCP to Sime Darby Berhad of Malaysia. However, operation and maintenance services are still handled by Fortum O & M Thailand Ltd. In August 2006, Sime Darby Berhad has fully taken over the operation of the plant from Fortum O & M Thailand Ltd. Sime Darby Berhad renamed the operation and maintenance company as Sime Darby O & M Thailand Co. Ltd. and since then has been running the plant with excellent performance record. In fact, in April 2008 both SPC and Sime Darby O & M Thailand Co., Ltd. have simultaneously achieved ISO 9001:2000, ISO14001:2004 and OHSAS 18001:2007 certifications demonstrating their commitment to quality in business management, care for the environment and ensuring a safe and healthy workplace for the employees.
Technical Overview
The Laem Chabang power plant consists of, two PG 6561 B (Frame 6B) gas turbines, two unfired heat recovery steam generators, one steam turbine and auxiliaries necessary to comprise an operational power plant. The maximum electrical output is 110MW in full condensing mode. The maximum steam production capability is around 50 tons/hr in medium and low pressures.
The fuel, natural gas, for the power plant comes via a three-km long 12” underground pipeline, which is connected to the PTT 28” main gas pipeline. There is a metering and pressure reduction station (“M/R station”) situated inside the power plant premises. The gas pipeline is owned by PTT, but the M/R station is owned by the Company. Back-up power supply is provided by PEA through the same 115kV bus bar that LCP sells power to EGAT. In the event of a forced outage, back-up power from PEA automatically comes in to serve the industrial customers.
Distribution Network
The sale of electrical energy to EGAT is sold via a 115-kV underground transmission line through a nearby sub-station operated by the Provincial Electricity Authority (PEA). Meanwhile, electricity is sold to industrial factories through a network of 115kV and 22kV power cables running throughout the Laem Chabang Industrial Estate. Steam energy is sold at medium and low pressures through a network of pipelines around the estate. Two steam pipelines, a 23-bar 10” diameter pipeline and a 10-bar 14” diameter pipeline delivers steam to the customers. Additionally there is a 3” condensate return pipeline from one medium pressure steam customer.
