Where the technical limits of a distribution system will be exceeded and the rectification options are likely to exceed $10M, Ergon Energy is required under the National Electricity Rules s5.6.2(f) to consult with affected Registered Participants, AEMO and Interested Parties within the time required for corrective action and meet certain requirements, including undertaking analysis that satisfies the AER’s Regulatory Test, in selection of an appropriate solution.

Ergon Energy Corporation Limited (Ergon Energy) identified emerging limitations in the electricity distribution network supplying the Emerald area in 2013. In accordance with the requirements of the National Electricity Rules, a Regulatory Test of suitable options was undertaken, which resulted in the publication of a Final Report on 20 May 2014.

The Final Report documented the evaluation of options and declared Ergon Energy’s intent to proceed with its internal option to construct a new dual circuit 66 kV line from Blackwater Substation to Emerald Substation.

Although the ENCAP Review, which resulted in new security standards did not trigger a change to the recommended option, further changes to the security standards that were recommended by the Inter-Departmental Committee and Independent Review Panel, and accepted by the Government, necessitated that Ergon Energy adopt a probabilistic approach to planning.

These changes, together with the firming of a large customer connection proposal in the area indicate that it would not be prudent and efficient for Ergon Energy to proceed with the works recommended in the Final Report.
