The Tonsley Network or Tonsley Natural Gas Network is an embedded distribution network that operates within the Tonsley Innovation District, Clovelly Park, south of Adelaide. It is owned and operated by Enwave Tonsley, part of Enwave Australia (Enwave Australia is a CleanPeak Energy business since August 2020).
The Tonsley Network is used to provide retriculated natural gas to up to 400 town houses (it also provides electricity and non-drinking water). It is not expected to supply natural gas to businesses in the innovation district.
The Tonsley Network is connected to the AGN SA distribution system.
The Tonsley Network is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). It was previously subject to the access regime for non-scheme pipelines under the former Part 23 of the NGR, which was replaced by Part 10.
The AER has granted the following exemptions for the Tonsley Network:
- On 13 August 2019, a five year Category 2 exemption under Part 23 of the NGR for the Tonsley network. Due to reforms to the NGR, the exemption transitioned to Category 2 under Part 10 of the NGR.
- On 11 September 2024, a five year Category 1 exemption under Part 10 of the NGR.
