In order to provide a stable power supply to all factories in industrial park, the step-up transformer unit (110KV-40MW) was installed to replace the previous 22KV-power network to ensure the stable power for production demand of the tenants in Long Binh Industrial Zone. This unit will be upgraded soon to reach the capacity of 80MW. Besides, the power plant at site with the capacity of 3.2MW constructed at the very beginning period is the back-up power when necessary.
