Project Overview

ElectraNet is exploring options that can facilitate South Australia’s energy transformation, while improving system security and helping lower electricity prices.

In November 2016, ElectraNet released a report for public consultation to explore options to facilitate South Australia’s energy transformation, while improving system security and helping to lower electricity prices. This report explored the technical and economic feasibility of a new interconnector as well as alternative non-network solution options.

During the consultation we received extensive feedback and input from electricity market participants and the wider community.

In June 2018, the Project Assessment Draft Report (PADR) was released. The report identifies that the construction of a new, high capacity interconnector between South Australia and New South Wales would deliver substantial net benefits to customers.

These net market benefits are estimated to be more than $1 billion over 21 years.

Independent modelling by ACIL Allen estimates that annual residential customer bills would reduce by up to about $30 in South Australia and $20 in New South Wales.

Interconnection with NSW would enable South Australia to increase renewable energy production and export it into the national market.

Based on current estimates, a new interconnector would cost $1.5 billion across both states, and subject to receiving all necessary environmental and development approvals, could be delivered between 2022 and 2024.

To deliver the project, ElectraNet would partner with TransGrid, the manager and operator of the high voltage electricity transmission network in NSW. Should the project be approved, TransGrid would fund the works within its jurisdiction.

Stakeholders, interest groups and members of the public are invited to have their say on the findings of the PADR, with submissions due by 24 August 2018. Submissions can be emailed to consultation@electranet.com.au.

The next step of the RIT-T process involves the publication of a Project Assessment Conclusions Report, which ElectraNet currently anticipates will be released by November 2018. The AER will then make the final ruling on whether the preferred option proceeds.

Below are the associated reports and information developed as part of the RIT-T.
