central west pipeline

The 255-kilometre Central West Pipeline (CWP) is a transmission pipeline that is supplied from the Moomba Sydney Pipeline at Marsden and transports gas to regional towns in western NSW, terminating at Dubbo. It connects to the Central Ranges Pipeline at Dubbo.

A diagram of the CWP can found here, showing:

100%

CWP is a covered pipeline under the access regime of the National Gas Law and the National Gas Rules, and provides light regulation services.

Australian Energy Regulator

Not applicable. Light access regulation has no explicit review dates.

The following standard services are offered on the Central West Pipeline, subject to available capacity:

• Firm Transport
• Operational Capacity Transfer

A description of these services, including the Standard Gas Transport Agreement (SGTA) can be found on the gas transmission services page.

The current tariff for Firm Transportation services contracted on this pipeline for at least 12 months from 1 July 2023 is:

• $4.22/GJ for Central West Pipeline deliveries (Dubbo, Parkes, Forbes and Narromine).
• $2.98/GJ for Central West Pipeline throughput to the Central Ranges Pipeline.

This tariff is based on that applying under the original 10-year access arrangement for this pipeline, which ceased in April 2010 when the CWP became a light regulation pipeline. APA has continued to escalate the tariff in line with the former access arrangement, applying an annual discount of 0.06% to the tariff as escalated by March on March CPI.

Tariffs for the Operational Capacity Transfer service can be found on the tariffs and terms page.

Non-standard services or alternative terms may be available by negotiation, subject to the service provider's statutory obligations regarding price discrimination.
