SMEC maintains a critical role in the realisation of the Baleh Hydroelectric Project (HEP), a significant endeavor led by Sarawak Energy Berhad. Located in Sarawak, East Malaysia, the Baleh HEP serves as a pivotal component within the Sarawak Corridor of Renewable Energy (SCORE) initiative. The primary objective of the project is to harness the hydropower potential of the region and attract energy-intensive industries, thus promoting economic growth and creating employment opportunities.

SMEC’s substantial involvement in this project can be attributed to its expertise in the design and construction of concrete-faced rockfill dams, cultivated over years of industry experience. The collaboration with the project dates back to 2015, commencing with vital contributions to tender design and evaluation, establishing a robust foundation for the project’s early stages.


The project’s infrastructure includes a colossal 188m-high concrete faced rockfill dam, a surface power plant with five 257MW Francis turbines, a radial gated spillway, diversion tunnels, pressure steel pipes, an intake structure and a double circuit 500kV power transmission line to integrate the electricity into Sarawak Energy Berhad’s grid. Other components consist of low-level outlet, jetty, bridges and access road to connect Kapit town to the project site.


Prior to the ongoing provision of construction supervision services, SMEC also reviewed the contractor’s design calculations and drawings, overseeing essential project components. This encompassed the evaluation of two 12-meter diameter diversion tunnels, a towering 188m-high concrete faced rockfill dam, and a radial gated spillway with a capacity of 16,500 cubic meters per second (m3/s).


Anticipated for completion in 2028, the Baleh HEP is expected to generate an impressive 1,285 MW of renewable energy, significantly transforming Sarawak’s energy landscape. SMEC’s continuous involvement underscores its indispensable contributions toward meeting Sarawak’s Energy demands and ensuring the successful realisation of this significant project as it advances toward completion.
