Andritz to upgrade Malaysia’s Chenderoh Hydropower Plant

Wedoany.com Report-Nov 12, Malaysia’s oldest hydropower plant, Chenderoh, is set for a major upgrade as part of a new rehabilitation project. TNB Power Generation has commissioned Andritz to perform an extensive uprating of the facility, aiming to extend its operational lifespan and increase the capacity of three generating units by 5%.

The contract, signed in September 2024, is valued in the high double-digit millions of euros. The Chenderoh plant, which last underwent a significant overhaul in the 1990s, has been running continuously since then. As part of this new project, Andritz will conduct major upgrades on the turbines and supply new generators. The company will also rehabilitate hydromechanical equipment and modernize the plant’s auxiliary systems.

Additional improvements include enhancing the safety and reliability of the cooling system for unit 4, as well as updating various support systems. Electrical systems will be upgraded, and new infrastructure, such as a generator transformer and a powerhouse crane, will be installed. The project encompasses engineering, construction, and commissioning of the electrical and mechanical equipment, along with necessary civil works.

The rehabilitation forms a key part of TNB’s “Life Extension Program,” which aims to modernize and maintain its hydropower assets. This effort reflects TNB’s commitment to ensuring the continued reliability and sustainability of Malaysia‘s power supply.
