The contract from Thai project developer Global Power Synergy Public Company Ltd (GPSC) is for the first phase of a 48 MW/140 MWth plant in the eastern coastal city of Rayong.
The plant will provide power and steam to industrial users in Hemaraj Eastern Industrial Estate.
According to Pöyry, the first project phase will consist of one gas turbine, one heat recovery steam generator (HRSG) with supplementary firing, steam and power distribution network to industrial consumers and auxiliary systems to support future expansion.
Pöyry's assignment includes assistance in project management, design review, site supervision services, quality assurance and control and commissioning supervision. The overall schedule for the contract is about two years, the firm said.
Pöyry had also been involved as owner's engineer during the development phase, providing technical advisory services.
Petteri Härkki, Pöyry’s regional director, said the project is “one of the first power plant projects using the new Siemens SGT 800B5 gas turbine, allowing greater efficiency in this size range”.
He added that his firm has had “a substantial role in the design and construction of about 50 power plant projects” in Thailand.
