Review of Electricity Transmission Reliability Standards
IPART has received terms of reference from the NSW Government to act in the role of economic advisor to review and recommend electricity transmission reliability standards to the Minister for Industry, Resources and Energy for TransGrid for the next regulatory control period (commencing 1 July 2018). Our terms of reference ask us to develop an economic framework to evaluate reliability standards and to use this approach to make a recommendation on what standards should apply. We provided our final report and recommendations to the Minister on 31 August 2016. The Minister will consider these recommendations before making a decision on what standards should apply. The standards we recommended include a level of redundancy and an allowance for expected unserved energy for each supply point across NSW. However, there are a number of supply points where we consider that further analysis and consultation is required before finalising the value of the expected unserved energy allowance. As a result, we have decided to release a supplementary draft report and seek submissions on a set of draft recommendations for these supply points before finalising our review. The supplementary draft report will cover the expected unserved energy allowances for Inner Sydney as well as a number of other supply points in regional NSW (Broken Hill, Mudgee, Munyang, Wellington Town and Molong). We expect to release the supplementary draft report on these in October and to provide a supplementary final report to the Minister by the end of the year. All documents and models that have been released for this review are available from the Reports, Decisions & Papers.
