South Australian Energy Transformation
ElectraNet has been exploring options to facilitate South Australia’s energy transformation, while helping to lower electricity prices and improve system security.
In November 2016, ElectraNet released a consultation report that explored the technical and economic feasibility of a new interconnector as well as alternative non-network solution options, through the Regulatory Investment Test for Transmission (RIT-T).
The RIT-T is the economic cost benefit test that is overseen by the Australian Energy Regulator (AER) and applies to all major network investments in the National Electricity Market.
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 identified that the construction of a new, high capacity interconnector between South Australia and New South Wales would deliver substantial net benefits to customers.
In February 2019 we released the SA Energy Transformation PACR which is the final step in the RIT-T process.
The PACR identifies that a high-capacity interconnector between South Australia and New South Wales, with an added connection to north west Victoria, is the preferred option to generate a range of benefits for South Australia, New South Wales and Victoria. These benefits include improved electricity affordability, energy and network security and the connection of renewable energy needed to meet Australia’s carbon emissions targets.
Residential customers should see annual savings on their electricity bills of $66 in South Australia and $30 in New South Wales. For small businesses annual savings are expected to be $132 in South Australia and $71 in New South Wales. These savings would start flowing as soon as the new interconnector is energised.
The proposed interconnector would be built between Robertstown in South Australia and Wagga Wagga via Buronga in New South Wales, with an added connection to Red Cliffs in north west Victoria.
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.
It is estimated the project will cost approximately $1.5 billion but will deliver around $2.45 billion in benefits, meaning the savings delivered by the project will exceed the construction costs paid by customers.
The next step of the RIT-T process involves the Australian Energy Regulator (AER) making a final decision as to whether the project will proceed. We anticipate that a decision will be made by the middle of 2019.
The project has also been given an official name – Project EnergyConnect. Ongoing updates regarding how stakeholders and community members can participate and engage with the project are available on the Project EnergyConnect website.
