Emerald (PDF, 197.1 KB)The Expressions of Interest for Emerald Reactive Support closed on 21 March 2017. We have received four expressions of interest which potentially meet the reactive support needs for Emerald Zone Substation. Following due diligence, we will seek formal approvals through normal governance and provide further direction for the for proponents.21 Apr 2017
Charleville (PDF, 1.4 MB)Non-Network Options ReportThe Static VAR Compensator (SVC) at Charleville zone substation is approaching the end of its design life and it is recommended for replacement on the basis of its age and reliability. The SVC performs the function of maintaining stable voltages at both high and low load times. The SVC also provides some Negative Phase Sequence (NPS) correction to address voltage balance issues associated with SWER networks. The SVC is critical to the provision of ongoing voltage/VAR support, and to meet Ergon Energy’s corporate strategic objectives. Without reactive compensation, 66kV supply at Charleville and the far south western Queensland suffers from poor voltage regulation. This report is an invitation to registered participants and interested parties to make submissions on credible options to address this identified need.12 Jan 201816 Apr 2018
Charleville (PDF, 361.0 KB)Non-Network Options ReportWe need to revise the release dates for the forthcoming publications under the RIT-D process for Charleville 66kV Voltage Management. An updated timetable for the remaining steps of this RIT-D process is presented in this notice.13 Jun 2018
Bundaberg (PDF, 1.6 MB)Screening for Non-Network Options ReportErgon Energy is responsible for the electricity supply in the Bundaberg region and does so via a network of substations all connected to the T020 Bundaberg bulk supply point. In its current state T020 Bundaberg will not meet the outage restoration times required under our service Safety Net obligations should a 132kV OR 66kV bus outage occur. To comply with Safety Net at Bundaberg T020 bulk supply point restoration must be completed with an hour or unserved load must be kept under 20MVA for the current 2 hour restoration time.Our preferred option is to install bus section circuit breakers and associated equipment to reduce restoration time to within an hour to comply with Safety Net for a cost of $7.3M. As T020 Bundaberg supplies between 30 – 112 MVA to the wider Bundaberg region, any non-network option must support between 6 MVA and 96 MVA for 2 hours until restoration is completed. We are publishing this notice under cl. 5.17.4(d) of the NER as it has determined that no non-network option is, or forms a significant part of any potential credible option.23 Apr 201825 May 2018
Bundaberg (PDF, 1.6 MB)Final Project Assessment ReportErgon Energy is responsible for the electricity supply in the Bundaberg region and does so via a network of substations all connected to the T020 Bundaberg bulk supply point. In its current state T020 Bundaberg will not meet the outage restoration times required under our service Safety Net obligations should a 132kV OR 66kV bus outage occur. To comply with our Safety Net at Bundaberg T020 bulk supply point restoration must be completed with an hour OR unserved load must be kept under 20MVA for the current 2 hour restoration time. 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 Safety Net requirements is the establishment of 66kV and 132kV bus section circuit breakers and associated equipment at T020 Bundaberg.23 Apr 201825 May 2018
South West Toowoomba (PDF, 2.2 MB)Non-Network Options ReportThe South Western edge of Toowoomba has experienced strong population and load growth in the communities of Westbrook, Drayton, Wyreema, Cambooya and Vale View. This growth is expected to continue. The existing Westbrook and Eiser St feeders predominantly supply these areas and are constrained in terms of voltage, capacity and performance of existing aged network. This report is an invitation to registered participants and interested parties to make submissions on credible options to address these constraints and identified need.04 May 201804 Aug 2018
Garbutt (PDF, 850.6 KB)Screening for Non-Network Options ReportGarbutt 132/66/11kV (T046) substation (GARB) is a Powerlink Queensland (PLQ) / Ergon Energy (EE) shared site with outdoor 132kV and 66kV assets and indoor 11kV assets, which supplies 48,500 customers and 86MVA of load (directly and indirectly). There is minimal forecast load growth at the substation however many assets are approaching or at the end of service life, with some equipment and the majority of structures 40-60 years old. The only credible option is the network solution for Garbutt 66kV Switchgear replacement with 66kV gas insulated switchgear at the existing Garbutt Substation. The estimated preferred project cost is $28,381,619 with an estimated average annual maintenance cost of $52,029. The project delivery is commencing design in 2019/2020 and construction completed by 2021/2022. Ergon Energy is publishing this notice under cl. 5.17.4(d) of the NER as it has determined that no non-network option is, or forms a significant part of any potential credible option.18 Jun 201831 Jul 2018
