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 is responsible (under its Distribution Authority) for electricity supply to the Charleville area in Southwest Queensland. Ergon Energy has identified emerging limitations in the electricity distribution network supplying the Charleville area. The peak load on the Roma – Charleville 66kV line is above the Security of Supply Criteria threshold of 15MVA, which triggers work to enhance security of supply. The Charleville area is supplied via a single 276km 66kV sub-transmission feeder from Roma Bulk Supply Point. With regards to Charleville’s performance against the security criteria, during the 2010/11 financial year the load was above 15MVA for a total of 56 hours, spread out over 6 days. 

Ergon Energy published a Request For Information (RFI) relating to this emerging network constraint on 23 May 2012 - 11 submissions were received by the closing date of 18 July 2012. 

The evaluation process eliminated options that presented "battery only" or "solar and battery” solutions due to their inability to meet the partial contingency / risk management definition.

The other proposals were evaluated and scored with the proponents of the top three diesel/hybrid options, a solar thermal option and a renewable power station option invited to present to the evaluation panel. 

This is now a Consultation & Draft Recommendation where Ergon Energy provides both economic and technical information about possible solutions, and our recommended solution to establish a diesel generation solution. 

Submissions (electronic preferably) are due by 3 July 2013 and should be lodged to:
