SMEC provided consultancy services for the management and engineering audit.

The project features a 205 m high concrete faced rockfill dam (the third highest dam of its type in the world) with a twin chute spillway of 15,000 m3/s total capacity. The power station comprises eight 300 MW nominal capacity generating units in a surface power station structure located at the base of the dam.


Each unit is supplied from a single power conduit ranging in size from 7 m diameter for the steel lined high pressure sections, to 8.5 m diameter for the concrete lined sections and shafts. The units are not equipped with inlet valves, and for unit isolation rely on hydraulically operated intake gates located on the power intake structure, adjacent to the spillway gates and draft tube outlet gates on the downstream wall of the power station.


The Bakun hydroelectric project is located in central Sarawak on the Balui tributary of the Rejang River, approximately 180 km by road east of Bintulu on the coast.
