The Tanjung Kidurong power project is an 826MW gas-fired, combined-cycle power project under construction in the Bintulu Province of Malaysia.

Sarawak Energy, the electric utility company of the Malaysian state of Sarawak, is the developer of the project, which involves the construction of two combined-cycle power blocks at the existing Bintulu power station.

The total investment on power blocks one and two are estimated to be £195.37m ($238.62m) and £273m ($364.41m). 

The construction works on block one were started in November 2016 and it was brought into commercial operation in January 2021.

The project is expected to achieve full capacity with the commissioning of the second block by the end of 2021. 

Location and site details 

The Tanjung Kidurong combined-cycle gas turbine (CCGT) project is located within the existing Tanjung Kidurong (Bintulu) power station, approximately 6km away from the Bintulu sea port, in the Kidurong Industrial Park, Bintulu province, Sarawak, Malaysia.

Tanjung Kidurong power project make-up 

The Tanjung Kidurong gas-fired power project consists of two combined-cycle blocks of 413MW net capacity each.

Each block is equipped with a GE F-class gas turbine, a steam turbine, and a waste heat recovery boiler in a multi-shaft configuration that also enables open-cycle, as well as dual fuel operations.

Incorporating innovative twin combustor design that involves the environmental vortex (EV) as well as the sequential EV (SEV) combustors, the gas turbine features low exhaust emission and greater operating flexibility.

The project will utilise an integrated cooling water system comprising three 1.1km-long and 2.5diameter sub-sea, high-density polyethylene (HDPE) water intake and drainage pipes.

Power evacuation

The electricity generated by the project will be evacuated into the grid through a 275kV power transmission line via a gas insulated substation (GIS).

Contractors involved 

A consortium of GE Power Solutions Malaysia, GE Switzerland, Sinohydro Corporation Malaysia and Sinohydro Corporation consortium was awarded the  engineering, procurement, and construction (EPC) contract for unit one of the Tanjung Kidurong combined-cycle power project in October 2016.

A similar contract for unit two was signed with the consortium of GE and Sinohydro Corporation in August 2018.

GE Power Services also signed a multiyear service agreement (MYA) for the facility in March 2017. The scope of the agreement includes technical support, major spare parts, productivity solutions, as well as training of employees.

China’s Eight Bureau of Power Construction Hydropower and Hubei Engineering Company Construction Company were engaged for the construction works of the project.

Vantage Steek Works and Kemuning Engineering were engaged for the supply, fabrication, and erection of steel structure.

Sarens was contracted for the equipment lifting and installation operations, while  Flenco was subcontracted by GE Switzerland for the supply of auxiliary systems for unit one of the combined-cycle project.

KASI Malaysia was appointed by Sinohydro Corporation for the marine traffic risk analysis (MTRA) of the cooling water intake pipeline.

Chemsain Consultant was engaged for the environmental and social impact assessment (ESIA) of the Tanjung Kidurong combined cycle power project.
