The Murum Hydroelectric Project is SEB’s largest construction project and marks the start of an ambitious expansion and development program of hydroelectric generation in the state to support the SCORE agenda. The Murum project has a capacity of 944MW and the expected average annual output is 5,542GWh. The hydroelectric scheme consists of a 141m high concrete Dam wall. This Dam controls a catchment area of about 2,750 km2. A Water Intake Tower at 53m tall is connected to the Powerhouse via a 2.7km twin tunnels with Surge Tanks.
The project developer is Sarawak Energy Berhad (SEB), Sarawak’s state-owned electricity generating company. Dam construction was supervised by China Three Gorges Corporation and undertaken by Chinese dam builder Sinohydro.
