AER reference: 


On 22 August 2019, Powercor submitted an application to the AER seeking a determination, with respect to the Victorian State regulatory requirement to install Rapid Earth Current Fault Limiters (REFCLs), that funding for a contingent project be approved and their maximum allowed revenue be adjusted in accordance with clause 6.6A.2 of the NER.

On 1 May 2016, the Electricity Safety (Bushfire Mitigation) Amendment Regulations 2016 (Amended Bushfire Mitigation Regulations) came into effect in Victoria. The amended regulations require Victorian distributors to install REFCLs at designated zone substations. The purpose of the REFCL devices is to reduce the risk of a bushfire caused by a fallen powerline. Powercor is required to meet a defined quota of zone substations with operational REFCLs by 1 May 2019 with an additional quota to be operational by 1 May 2021 and the remaining designated zone substations fitted with REFCLs by 1 May 2023.

This contingent project application seeks funding for the third (and final) tranche of REFCL installations and associated works for the following zone substations:

  • Ararat
  • Corio
  • Hamilton
  • Koroit
  • Merbein
  • Stawell
  • Terang

The installation of REFCLs will necessitate other capital replacement and upgrade works across the distribution network. Powercor's application seeks funding of expenditure for both REFCL installation and consequent works.

Invitation for submissions

We invite interested stakeholders to make written submissions in response to Powercor's contingent project application regarding the third tranche of installation of Rapid Earth Current Fault Limiters (REFCLs) . Submissions will be accepted until the close of business 27 September 2019.
