The Wickham Point Pipeline (WPP) is a lateral transmission pipeline in the north-west region of the Northern Territory near Darwin. The pipeline is owned by Energy Infrastructure Investments (EII) and is operated by the APA Group. The APA Group has a 19.9 per cent interest in Energy Infrastructure Investments. The other companies involved in EII are Marubini (49.9 per cent interest) and Osaka Gas (30.2 per cent interest).
The WPP is 12 km in length and has a maximum gas flow capacity of 90 TJ/day. It was built to deliver gas on an emergency supply basis from the LNG Plant at Wickham Point to the Amadeus Gas Pipeline and Power and Water Corporation’s Weddell Power Station near Darwin. The section of the WPP from Darwin City Gate WPP to Weddell Power Station has been in operation since early 2008, while the remainder of the pipeline between the Weddell Power Station and the Wickham Regulating Station was commissioned in May 2009.
The Wickham Point Pipeline is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Chapter 6A of the NGL and Part 23 of the NGR. On 3 January 2018, the AER granted a 5 year category 2 exemption under Part 23 of the NGR for the Wickham Point Pipeline alongside their determination for the Weddell Lateral.
