Construction work has begun on the 300MW Nenggiri hydroelectric project in Malaysia, with the official groundbreaking ceremony having taken place in mid June.

The ceremony, on 12 June, was attended by high-ranking delegations from government and industry as well as by the customer and owner, Tenaga Nasional Berhad (TNB), and members from the Andritz-led consortium that are supplying the electromechanical and hydromechanical equipment.

With commissioning expected by mid-2026, the Nenggiri Hydroelectric plant will provide peak load coverage to stabilize the national grid as well as flood mitigation benefits for the downstream areas. At the peak of the construction work, it will provide about 2,000 job opportunities to the local people and the possibility of developing further spin-off jobs in tourism and agriculture.

Once completed, the Nenggiri dam will generate approximately 600 GWh of renewable energy annually. This project is part of several government-approved projects to meet the growing energy demand in Malaysia and increase the share of renewable energy in the country’s energy mix to 40% by 2035. It is the largest single renewable energy project currently being implemented in Malaysia by TNB

The Andritz scope of supply for the project includes two Francis-type turbine-generating units as well as the complete mechanical and electrical balance of plant, the hydromechanical equipment, and the high-voltage switchyard.
