Project Overview

The proposed Tekai Hydroelectric is located on the Tekai River in West Malaysia.

Studies by Japan International Cooperation Agency (JICA), identified that a hydropower development comprising two cascading dams, namely the 105 m high Upper Tekai Dam and the 24 m high Lower Tekai Dam, with 165 MW and 6 MW power stations would be technically feasible and economically viable.

The 165 MW Upper Tekai power station will be operated as a peaking station for approximately 5 hours daily, while the Lower Tekai Dam acts as a regulating weir releasing water at a constant rate 24 hours a day, 7 days a week back into the Tekai River.

The project also includes the construction of 25 km of roadway and residential quarters for Operation and Maintenance (O&M) personnel.

Upon completion, the dam will create a storage reservoir of 8,520 ha and provide 164 GWh of peaking energy annually.

Due to the scale of this project, it is a mandatory requirement to carry out a Detailed Environmental Impact Assessment (DEIA) as per Malaysia’s Environmental Act 1974 and to obtain an approval from the Department of Environment. An Environmental Management Plan (EMP) is also prepared and approved before the construction commences.
