| Boyne (PDF, 197.9 KB) | Notice of Withdrawal | Ergon Energy identified emerging limitations in the electricity distribution network supplying Boyne Island in 2013. A Regulatory Test of suitable options was undertaken, resulting in the decision to upgrade the Boyne Residential Substation and construct an additional 66kV line. However, changes to the security standards that were recommended by the Inter-Departmental Committee and Independent Review Panel, and accepted by the Government, necessitated that we adopt a probabilistic approach to planning. As a consequence, we consider that the proposed works are no longer required to address an identified need in the timeframe referred to in the original consultation. Therefore, we have decided to withdraw the recommendation to augment the Boyne Residential Substation and construct an additional 66kV feeder. | 12 Oct 2015 | |
| Cannonvale (PDF, 196.2 KB) | Notice of Withdrawal | Ergon Energy identified emerging limitations in the electricity distribution network supplying Cannonvale in 2010. A Regulatory Test of suitable options was undertaken, resulting in the decision to construct a 66kV switchyard at Cannonvale and construct an additional 66kV line. However, changes to the security standards that were recommended by the Inter-Departmental Committee and Independent Review Panel, and accepted by the Government, necessitated that we adopt a probabilistic approach to planning. As a consequence, we consider that the proposed works are no longer required to address an identified need in the timeframe referred to in the original consultation. Therefore, we have decided to withdraw the recommendation to augment the Cannonvale Substation and construct an additional 66kV feeder. | 12 Oct 2015 | |
| Charleville (PDF, 220.6 KB) | Notice of Withdrawal | Ergon Energy identified emerging limitations in the electricity distribution network supplying Charleville in 2012. A Regulatory Test of suitable options was undertaken, resulting in the decision to develop a diesel generation solution for the region. However, changes to the security standards that were recommended by the Inter-Departmental Committee and Independent Review Panel, and accepted by the Government, necessitated that we adopt a probabilistic approach to planning. As a consequence, we consider that the proposed works are no longer required to address an identified need in the timeframe referred to in the original consultation.
Therefore, we have decided to withdraw the recommendation to complete the diesel generation solution for the Charleville region on the basis that it would not be prudent and efficient to proceed with the works. | 30 Sep 2015 | |
| Charlton Area (PDF, 1.2 MB) | Final Project Assessment Report | Ergon Energy is responsible for electricity supply to the Charlton, Wellcamp, Kingsthorpe and Westbrook areas, west of Toowoomba. We have identified emerging limitations in the electricity distribution network supplying the area, as the load on the Torrington 110/33/11kV substation has been steadily increasing due to increasing numbers of residential, commercial and industrial customers. The region is poised for further significant growth. Should additional works not be completed in this region, it is likely that significant voltage and capacity constraints could present when additional customers begin to connect. We have determined that there will not be a non-network option that is a potential credible option, or that forms a significant part of a potential credible option. As per the “Screening for non-network options report”, we determined that the most appropriate technical and economic network solution to the network constraint was the establishment of a 33/11kV, 10MVA Skid Substation on the corner of Meehan and Wirth Roads, Charlton. | 30 Sep 2015 | 30 Oct 2015 |
| Emerald (PDF, 2.2 MB) | Draft Project Assessment Report | Ergon Energy Corporation Limited (Ergon Energy) is responsible (under its Distribution Authority) for electricity supply to the Emerald area in central Queensland. The maximum demand at Emerald is presently 39.7MVA and is forecast to grow by approximately 1.7% per annum for the next 10 years. The existing 66kV network does not have sufficient capability to supply the forecast increased load at Emerald under system normal conditions, and voltage constraints may start to occur within five years. Ergon Energy has also received connection enquiries from two major customers in the Emerald area. Connection of either one of them will bring forward the date voltage constraints may start to occur such that additional network capability will be required before connection can be offered. Ergon Energy’s preferred solution to address the identified need at Emerald is to install additional reactive compensation at Emerald Zone Substation, and to upgrade the Emerald – Blackwater 66kV Feeder to increase its thermal rating. | 01 Jun 2016 | 29 Jul 2016 |
| Gracemere Area (PDF, 1.7 MB) | Final Report | Ergon Energy has identified increasing risks to reliable supply in the electricity distribution network supplying the Gracemere area. A Regulatory Test was completed (though the requirement for consultation changed during the process). The loads on Ergon Energy’s Malchi 66/11kV Zone Substation and subsequent 11kV network have progressively increased such that the Regulatory Test is satisfied via the Market Benefits limb for construction of a compact substation at the Gracemere site (a New Small New Network Asset), with completion by November 2018. | 05 May 2016 | |
