Electricity and Steam
The electricity and steam are produced by Co-generation Plant for Petrochemical Businesses in Kertih and Gebeng. Our Co-generation Plant can generate electricity at high level of efficiency with lower amount of fuel gas. Since this energy is generated on-site, the load on the power network is minimised, and transmission line losses are prevented.
Fuelled by natural gas, the plant has combined export capacity of 350 MW of electricity and up to 1,320 tph of steam.
We offer wide range of electricity and steam specification

Treated Water
PGB’s centralised utilities and facilities distribute efficient and reliable utilities for petrochemical business within Kertih and Gebeng. These include various types of treated water – demineralised, boiler feed, cooling and wastewater treatment.
Demineralised Water
Demineralised water is specially purified water that has had most, or all of its mineral and salt ions removed through deionisation via resin exchange.
Market Application
- Feed water for high pressure boilers
- Steam driven turbines
- Manufacturing industries
- Healthcare
- Pharmaceutical
Boiler Feedwater
Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. To protect the boiler from contaminants which can cause corrosion, they should be controlled or removed, trough external or internal treatment. PGB’s produce and supply high purity boiler feed water through deaeration process for petrochemical industries.
Cooling water
Cooling water flows through a closed piping system that circulates water through various pieces of equipment.
Wastewater treatment
PGB’s Effluent Treatment Plant (ETP) is a secondary treatment system that used the activated sludge process to treat the combined effluents from Petrochemical Plants in Kertih. The effluents are treated to meet Malaysia Environmental Quality Act 1979, Third Schedule Standard B.
