Sarawak Energy has engaged SMEC to conduct the feasibility study and tender design for an extension of Bakun Hydroelectric Power Plant in Malaysia.
Following the completion of the pre-feasibility study last year, SMEC was engaged to provide an in-depth analysis on the possibility of increasing the existing hydropower scheme capacity, without interrupting the operation of the existing power plant and without drawing down the reservoir level.
In the pre-feasibility report, it was suggested that a 300MW extension was possible by constructing a 1.2km-long, 8.5m-diameter headrace tunnel through the dam’s right abutment to a new underground power station. The new power station will have a single 300MW generator unit that will utilise the redundant 12m-diameter diversion tunnels of the existing scheme as the new tailrace.
SMEC’s project team will review the pre-feasibility study and confirm the development option for the extension. Other services to be provided include a Hazard and Operability (HAZOP) study, concept study report, basis of design for civil, electrical and mechanical aspects, tender design report, tender specification and drawings, training of client personnel and generic specification for SCADA, communications, controls and protection.
The existing 2400MW Bakun Power Station is located in central Sarawak on the Balui tributary of the Rejang River.
