Updates from the Ulu Jelai Dam Project

Another milestone has been reached in the Ulu Jelai Dam project in Malaysia with the completion of the RCC (Roller Compacted Concrete) works on the Susu Dam, a specialised process involving the continual laying down of thin layers of concrete, carefully compacted one by one.

The Ulu Jelai hydroelectric project site is located approximately 200 km north of Kuala Lumpur in the state of Pahang; the project is divided into three different lots. Lot number two (Lot CW2-EM1) represents the main component of the project. The work on this lot includes the construction of the Susu Dam on the Bertam River which is more than 80 metres high and it is entirely built adopting the advanced RCC technology, with a total volume of about 750,000 m3.

The project involves the construction of an underground power able to house two francis turbines with a power output of 191 MW each. It also includes the construction of approximately 26 km of tunnels, 15 km will be approximately excavated with a Tunnel Boring Machine (TBM) and the remaining ones with the traditional method of Drilling and Blasting – NATM. The total installed power of the system will be 382 MW.

The Ulu Jelai project, which has already received international recognition for Safety and other factors, is very important for Pahang’s socioeconomic development. It will boost national energy production, which will consequently attract more foreign investments in the Country.
