WA: Parmelia Gas Pipeline

WA: Parmelia Gas Pipeline

The Parmelia Gas Pipeline (PGP) is a transmission lateral pipeline located in west and south-west Western Australia. The pipeline was originally known as the Western Australian Natural Gas (WANG) Pipeline. The PGP is owned and operated by the APA Group.  

The Parmelia Gas Pipeline is 445 km in length and has a capacity of 70 TJ/day. It transports gas from the Perth basin fields around Dongara (south of Geraldton) and the Carnavon Basin (via the Dampier to Bunbury National Gas Pipeline) to end-users in the Perth area. Gas from the PGP can be delivered into the Mondarra Gas Storage Facility, and gas withdrawn from the facility can be transported through the PGP to end-users. 

The PGP 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.

In December 2000, an Access Arrangement submitted by the pipeline’s then-owner CMS Gas Transmission of Australia was approved under the Gas Pipelines Access (Western Australia) Act 1998. Coverage was revoked in 2002.  

Construction of the Parmelia Gas Pipeline was completed in 1971.
