The Ulu Jelai hydroelectric project is currently under way in Malaysia. The project consists of a first lot for the access roads (CW1) and a second lot (CW2+EM1) for construction of an RCC (Roller Compacted Concrete) dam some 90 meters high, and a 382-MW underground hydroelectric power plant, including hydroelectric and mechanical equipment with catchment works and approximately 25 km of tunnels.
In December 2013, a third lot of the project (CW3) consisting of rockfill protection of the basin’s shores was awarded, valued at about € 70 million, bringing the value of the contract to approximately € 598 million.
The construction work, carried out by the subsidiary Salini Malaysia Sdn Bhd as part of a consortium with local partner Tindakan Mewah Sdn Bhd (Salini Malaysia 90%), will continue until 2016. The first lot of the project for the access road has been completed and delivered. As for the main lot consisting of the dam and hydroelectric plant, dam excavation and the river diversion works have been completed, while excavation on the underground plant and tunnels of the plant headrace and tailrace system are at an advanced stage of completion. The electromechanical components are currently being installed in the plant.
For the third lot of the project, the mobilization phase has been completed and the consolidation works using rockfill have started with about 250,000 m3 of rockfill, filters and drains placed, the construction of access roads and the diversion of the river in two places. River diversion works at the third point are currently underway and will be completed before the end of November 2014.
The percentage of work completion as of September 30, 2014, was 72.4%.
