The Tonsley distribution network is an embedded 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 gas network is connected to the AGN SA distribution system.
