The Envestra (SA) gas network is a distribution pipeline owned by Australian Gas Networks (AGN – formerly known as Envestra Limited) who outsources the operation of the network to the APA Group. Envestra was created in 1997 when networks in South Australia, Queensland and the Northern Territory that were owned by the former South Australian Gas Company, Gas Corporation of Queensland and Centre Gas Pty Ltd were combined into one entity.
The Envestra (SA) gas network covers Adelaide and its surrounds, and the regional centres of Mount Gambier, Whyalla, Port Pirie, Barossa Valley, Murray Bridge and Berri. It consists of approximately 7,786 km of pipeline delivering gas to around 410 000 customers.
The Envestra (SA) gas network is connected to the MAPS, SEA Gas, South East and Riverland transmission pipelines.
The Envestra (SA) gas network was subject to regulation as a covered pipeline under the Gas Code by ESCOSA (formerly SAIPAR). Under the National Gas (South Australia) Regulations, the Envestra (SA) gas network is classified as a ‘designated pipeline’. This means that under the NGL (ss. 109 and 111) the Envestra (SA) gas network remains under full regulation and cannot be the subject of a light regulation determination.
The Envestra (SA) gas network is subject to full regulation by the AER under the NGR.
