Water Management

SUSTAINABLE POWER PLANT OPERATIONS THROUGH

EFFICIENT WATER CONSUMPTION

Tenaga Nasional Berhad (TNB), as a utility company with substantial water usage in
power generation, we recognize our responsibility to manage this vital resource in a
sustainable manner.
Despite the withdrawal of water from seawater, surface water and town water for
our operations, 99.9% of the water withdrawal is discharged back to the respective
sources. Therefore, our focus in managing water withdrawal is on optimizing the use
of the 0.1% town water withdrawal, which is mainly used in power generation operated
by TNB Genco, a wholly-owned subsidiary of TNB. By treating the wastewater, 0.013%
of the 0.1% of town water we withdraw is safely discharged back into nature. Thus,
the main efforts are concentrated on optimizing the use of the remaining town water
withdrawal through operational excellence, technologies, and innovation.
