The SA distribution 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 SA gas distribution network is classified as a ‘designated pipeline’ which means that the SA gas distribution network:
- remained under full regulation and could not be the subject of a light regulation determination (see sections 109 and 111 of the NGL prior to March 2023)
- is currently a scheme pipeline and cannot be the subject of a scheme pipeline revocation determination (see section 97(1) of the NGL).
