KUCHING: Sarawak Energy will be implementing the next stage of system upgrades to its Batang Ai Hydroelectric Plant (HEP) until August.
This is to streamline the power plant’s system to enable better management of power generation and water resources while enhancing the plant’s efficiency and reliability.
The first stage of the system upgrading works for the automation project was undertaken over May 17 to 21 without affecting the local water supply.
The plant resumed operation of all four generating units on May 22 this year.
During the upcoming planned shutdown, with lower water discharge from Batang Ai HEP, lower water levels downstream may potentially affect downstream water supply.
The planned shutdown for Stage 2 and 3 upgrades will now take place from July 27 to Aug 8, and Aug 24 to 25, to enhance the reliability of the plant and contribute to grid stability.
Following the completion of Stage 1, date adjustments were made for the subsequent stages to ensure all necessary arrangements were thoroughly addressed prior to execution of the stages, to minimise any potential disruptions and inconvenience to customers.
During the Stage 2 and 3 upgrades, turbine operations will once again be temporarily suspended.
The Cooling Water System and Fire Hydrant System will continue discharging minimal water for environmental flow (or minimum riparian flow) downstream.
Sarawak Energy will also work with the Sarawak Rural Water Supply Department on alternative water supply solutions if necessary.
Sarawak Energy has assured the neighbouring communities that all measures are in place to mitigate any impact on the power supply.
Alternative arrangements and backup power sources will also be utilised to ensure continuous and reliable electricity supply throughout the shutdown period.
