Update on Heywood Interconnector upgrade
AEMO ELECTRICITY MARKET NOTICE
Update on Heywood Interconnector upgrade
Refer to Market Notice 51916
ElectraNet expects to achieve commercial operation of the South East - Tailem Bend 275 kV line series compensation by 31 July 2016. At this time, capability of the Heywood interconnector will be 570 MW for transfer from Victoria to South Australia and 500 MW for transfer from South Australia to Victoria. Further transfer capability will be released subject to completion of inter-network testing to prove system performance and validate system models. System conditions for the conduct of these tests are being obtained through normal market dispatch.
Based on progress with the testing to date, full capability for transfer from Victoria to South Australia is likely to be achieved by February 2017. However, it appears unlikely that the market will deliver sufficient test conditions to enable achievement of full capability for transfer from South Australia to Victoria before March 2017.
If the full range of required conditions are not obtained by July 2017, AEMO and ElectraNet may seek to obtain test facilitation services in order to complete the inter-network tests. This will allow the market approximately 12 months to deliver the required test conditions from when the South East - Tailem Bend series compensation is commissioned.
The inter-network test program for the Heywood interconnector upgrade provides further information and is published on AEMO's website at the following link:
