On 21 June 2017, the AER decided to waive SA Power Networks' obligation to comply with clauses 3.1, 4.2 and 4.4.1(a) of the Ring-fencing Guideline from 21 June 2017 until 1 June 2020 for SA Power Networks' temporary generation project. This is on the following conditions:

• that the temporary generation capacity is only utilised for the purpose of avoiding load shedding for NEM operational purposes when there is no alternative generation available
• is only utilised at the direction of AEMO or the South Australian Energy Minister
• is fully funded by the South Australian Government, who also receives all revenues from the project, and
• SA Power Networks cannot (and will not) advertise or promote other merchant generation services.

SA Power Networks will be expected to comply with the Guideline in all other circumstances, and in all other respects.
