On 24 May 2010, the AER granted the Applicants an exemption from the requirement to register as a network service provider and the operation of Chapter 5 of the National Electricity Rules. The exemption was granted under clause 2.5.1 of the NER in accordance with the AER's former Electricity NSP Registration Exemption Guideline, and was subject to the conditions set out in the Exemption Instrument.
On 27 September 2011, the Applicants sought a variation to the exemption. This exemption was repealed and replaced with a new network exemption (reference number AER 0002/11).
