EnergyAustralia Distribution Network Final Report – Replacement of 33kV Feeders to Lindfield Zone Substation
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 Stanthorpe area in Southern Queensland. We have identified emerging limitations in the electricity distribution network supplying the township of Stanthorpe and its surrounds. The load on Ergon Energy’s 110kV line supplying Stanthorpe has progressively increased such that augmentation to the network is required if reliable supply is to be maintained.
To meet the planning criteria for the Stanthorpe situation, Ergon Energy needs an additional minimum of 25MVA of capacity to be provided to this area. This size has been matched to expected load requirements within Ergon Energy’s typical planning horizon (being 15 years for transmission network).
In order to ensure that security of supply to customers in the Stanthorpe area complies with Ergon Energy’s network security criteria, corrective action will be required to be completed as soon as feasible, but no later than December 2012. A decision about the selected option is required by June 2010 if any option involving significant construction is to be completed by December 2012.
This is a Request for Information where Ergon Energy is seeking information about possible solutions to the emerging limitations which may be able to be provided by parties other than Ergon Energy.
