Pöyry wins CHP awards in Thailand and Finland

15 May 2018

Global Power Synergy Public Company Limited (GPSC) has awarded Pöyry the owner’s engineer services assignment for Central Utility Plant 4, Phase 1 (CUP4.1), a 48 MWe, 140 t/h steam, cogeneration project in Rayong, Thailand.

This first phase of the project will consist of one gas turbine, one heat recovery steam generator with supplementary firing plus connections via the steam and power distribution network to industrial consumers, and auxiliary systems to support future expansion. The gas fuelled plant will provide electricity and steam to industrial users in Hemaraj Eastern Industrial Estate in Thailand.

Pöyry’s assignment includes assistance in project management, design review, site supervision services, quality assurance and control and commissioning supervision. The overall duration of Pöyry’s activities will be about two years. It is a continuation of Pöyry’s earlier assignment within the same project, where Pöyry acted as owner’s engineer during the development phase, providing technical advisory services to the project owner.

It will be one of the first power plant projects to use the new Siemens SGT 800B5 gas turbine, providing higher efficiency in this size range.

Meanwhile in Finland, two municipal energy companies, Pori Energia Oy and Oulun Energia Oy have recently awarded Pöyry EPCM (engineering, procurement and construction management) services contracts for combined heat and power plants in Finland, both planning to use a similar fuel diet of biofuels, peat and recovered fuel.

The Pori Energia contract is for the Aittaluoto CHP plant, expected to be completed by mid-2020. Once in operation it will replace some of the existing boiler capacity at Aittaluoto. The new facility will have a boiler capacity of around 90 MW and it will supply heat to the city of Pori, process steam to neighbouring industrial clients and power to the grid.

The Oulun Energia project is the Laanila bio power plant in Oulu, where construction is due to be completed in late 2020. Once in operation it will replace Toppila unit 1. The installed capacity of the Laanila plant will be around 70 MWe and around 175 MWt of district heat, with an option to supply steam to industry clients in the Laanila area.
