LIFE EXTENSION PROGRAMME OF SUNGAI PERAK HYDROELECTRIC STATIONS
The Sungai Perak Hydroelectric Stations comprise five TNB’s hydroelectric stations namely Temengor, Bersia, Kenering, Chenderoh and Sungai Piah (Upper & Lower) hydroelectric stations.
The hydroelectric stations form a cascade system along the Perak River to generate electricity. Whereas, the upper and lower hydroelectric stations of Sungai Piah are served by Piah River which drain into the Kenering reservoir. The Temengor, Bersia, Kenering, Chenderoh and Sungai Piah hydroelectric stations generate about 2,254 GWh of energy annually. The combined installed capacity of these hydroelectric stations is approximately 648 MW.
The Service Level Agreement (SLA) between TNB and Regulatory Economics and Planning Division for operation and maintenance of hydroelectric stations will expire in August 2022. TNB intent to extend the life span of the hydropower stations by another 30 years after expiry of current SLA.
