Southern Power Generation Sdn Bhd has awarded Pöyry an owner’s engineer services assignment for a 1440 MW combined cycle power plant project in Johor, Malaysia. Southern Power Generation is a project company established for this independent power producer project and owned by Malaysian state-owned power utility Tenaga Nasional Berhad (TNB) and SIPP Energy Sdn Bhd.

The project consists of two 720 MW natural gas fuelled combined cycle blocks, with distillate as backup fuel. Each block consists of a GE 9HA.02 gas turbine, triple pressure reheat once-through type heat recovery steam generator and steam turbine in single shaft configuration. The project also includes a new 275/132 kV air insulated substation and a new 132 kV gas insulated substation. The plant will be located adjacent to the existing Sultan Iskandar power station at Pasir Gudang, Johor.

Pöyry’s scope includes assistance with project management, design review, site supervision services, quality assurance and quality control, commissioning supervision services and services during the warranty period. Pöyry is being assisted by its local partner, Minconsult Sdn Bhd. The overall duration of Pöyry’s involvement with the project is expected to be about four years.

“We are honoured that Tenaga Nasional Berhad and SIPP Energy have selected Pöyry as the owner’s engineer for this important project. This project is an essential part of Malaysia’s power development plan, needed to ensure reliable electricity supply for the country’s growing economy over the next two decades. This is also one of the first power plant projects globally using the new advanced GE 9HA.02 gas turbines, allowing very high power generation efficiency” says Petteri Härkki, Regional Director of Pöyry.
