On 13 December 2013, ElectraNet submitted an application to the AER seeking a determination, with respect to the proposed South Australia–Victoria (Heywood) Interconnector Upgrade, that funding for a contingent project be approved and their maximum allowed revenue be adjusted in accordance with clause 6A.8.2 of the NER.
Earlier, on 4 September 2013, in accordance with the requirements under clause 5.16.6 of the National Electricity Rules (NER), the AER published its determination on whether the preferred option identified in the Heywood Interconnector Upgrade satisfies the RIT-T.
The ElectraNet project involves the installation of new equipment to upgrade the 275kV transmission lines linking Victoria to South Australia and reconfiguration of the 132kV network in South Australia. Associated with this work is a project to be undertaken in Victoria by the Australian Energy Market Operator to upgrade transformer capacity at Heywood. The combined project will increase the power transfer capability between Victoria and South Australia.
The AER released its final decision on 31 March 2014.
