APA Group is the owner and operator of Port Hedland assets and power supply operations.

APA Group owns and operates the Port Hedland Power Station and the APA Group 66kV transmission network (APA Group Network). The APA Group Network connects the Port Hedland Power Station to the North West Interconnected System (NWIS) at Wedgefield and Murdoch Drive substations.

The Port Hedland Power Station is a large gas-fired power station. APA Group supplies electricity from the Port Hedland Power Station to a small number of large use customers in the Port Hedland region.

The Western Australian Government has undertaken market reforms to enable competition in the NWIS. As part of this process, APA Group’s Network is now a ‘covered network’ which makes it subject to new regulations under the Pilbara Networks Access Code (PNAC).

Pilbara Electricity Network Access Regulation

Regulation of APA Group’s Port Hedland transmission network commenced on 1 July 2021. This regulation is incorporated under the light-handed third-party network access regime of the PNAC.

Regulation under the PNAC focuses on the NWIS, which has three main operators of electricity networks: APA Group, Horizon Power and Rio Tinto. An Independent System Operator (ISO) performs power system oversight in accordance with the Pilbara Networks Rules (which includes administration of the Harmonised Technical Rules).

This website ensures that current and future customers in the NWIS have access to all relevant information on the APA Group Network.
