Ergon Energy Corporation Limited Request For Information – Supply To Bundaberg Area Emerging Distribution Network Constraint
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 Bundaberg area in southern Queensland. We have identified emerging limitations in the electricity distribution network supplying Bundaberg. The loads on Ergon Energy’s zone substations and 66kV network in Bundaberg have progressively increased such that augmentation is required if reliable supply is to be maintained.
To meet the security of supply criteria for the Bundaberg area Ergon Energy needs an additional minimum of 51MVA firm capacity at 66kV to be provided to this area. This size has been matched to expected load requirements within Ergon Energy’s typical 10 year planning horizon.
In order to ensure that supply to customers in the Bundaberg area complies with Ergon Energy’s security of supply criteria, initial corrective action will be required to be completed prior to the summer of 2010/11. A decision about the selected option is required by June 2010 if any option involving significant construction is to be completed by June 2013.
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.
Submissions in writing (electronic preferably) are due by 7 April 2010 and should be lodged to:
