Pilbara Pipeline System



The Pilbara Pipeline System (PPS) comprises five transmission pipelines extending from the North West Shelf Joint Venture’s Karratha Gas Plant to Port Hedland:

  • The 24-kilometre Burrup Extension Pipeline that links Woodside’s Karratha Gas Plant with the Pilbara Energy Pipeline at the Dampier to Bunbury Natural Gas Pipeline Mainline Valve 7, 20-kilometres south of Karratha.
  • The 216-kilometre Pilbara Energy Pipeline that transports gas from the Burrup Extension Pipeline, along the Pilbara Coast to Port Hedland, where it interconnects with the Telfer Gas Pipeline.
  • The 5-kilometre Karratha Lateral that transports gas to the Horizon Power Station at Karratha.
  • The 6-kilometre HBI Lateral transports gas from Port Hedland to Alinta Energy’s Port Hedland Power Station.
  • The 0.2-kilometre Boodarie Gas Lateral that runs to the (now closed) Solomon CNG plant.

Customers on the Pilbara Pipeline System comprise both power generation and mining operations.

Policies, Procedures and Requirements

Metering and Measurement

Metering and Measurement obligations are outlined in the SGTA (West) and for this pipeline are set out here.

Gas Specification

In Western Australia, transmission pipeline gas specifications are governed by State legislation – the Gas Supply (Gas Quality Specifications) Act 2009 (2009 Act) – and by regulations made under that Act. The 2009 Act provides for a Western Australian standard specification, which is set out in the regulations (with some variations for particular pipelines), and a reference specification for each pipeline. These specifications are necessary for the operation of the scheme of the legislation.

The standard gas quality specification for the PPS is set out in clause 1 of Schedule 1 to the Western Australian Gas Supply (Gas Quality Specifications) Regulations 2010. The reference specifications for the PPS are set out in clause 3B of Schedule 2 to the Regulations.

APA will measure and/or monitor gas quality in accordance with relevant obligations under contract. Quality obligations are outlined in the SGTA (West).

Credit support

APA has minimum credit support requirements that are a pre-condition to gaining access to pipeline services. APA’s credit support requirements are set out here.

APA Financial Information Disclosure – Part 23 National Gas Rules

APA is reporting financial information for its non-scheme pipelines — that is, pipelines that are not subject to full or light regulation, according to ERA’s Financial Reporting Guideline for non-Scheme Pipelines. The financial information for the six months to 30 June 2018 and the years ending 30 June 2019 - 2023 includes Pipeline Financial Statements based on Australian Accounting Standards, the weighted average price for services on each of these pipelines, and the number derived using the ERA recovered capital method (RCM).

Interested parties should read APA’s Basis of Preparation together with the completed financial information template that was developed by the ERA.

In addition, APA advises in relation to RCM:

  1. The assumed initial capital structure is 40% equity and 60% debt. The level of equity will increase in circumstances where there is a shortfall in annual revenue.
  2. The return on equity is a commercial return applicable in a workably competitive market. Historically, this return for an established pipeline was in the range of 9-11%, depending on factors such as risk, terms and counterparty.
  3. The cost of debt is based on a 10-year rolling average of a market rate applicable for an entity whose business is solely the ownership and operatorship of the particular pipeline.
