OUR RESTORATION PROCESS

At PNG Power we restore power to our vast network of transmission lines, distribution powerlines, substations, neighbourhood transformers, and service wires to customers in order of priority.

We use a sequence that is common to the electricity industry both in PNG and worldwide.
Our focus is on first restoring power to public health and community facilities and to the greatest number of customers as quickly as possible.

The typical sequence in the restoration process is as follows. However, many of these activities take place simultaneously.

  1. Transmission, substation equipment and main distribution powerlines. High voltage transmission lines supply power to large numbers of customers and to large geographic areas. Distribution substations and distribution powerlines serve a critical linking and switching function in our system. Protecting and repairing damage to these three components is our first priority.

  1. Essential facilities in our communities including emergency service and critical community infrastructure such as hospitals, police, fire brigade, and water treatment and pumping facilities. Efforts to restore power to these facilities are a priority.

  1. Distribution powerlines. Our next priority is to restore power to the largest number of customers as quickly as possible. This involves distribution powerlines which connect to individual locations such as powerlines in local streets. Repairs are then made to distribution transformers and, finally, service wires to individual homes and businesses.
