With the introduction of the National Energy Retail Law, the National Electricity Rules and the National Gas Rules have been amended to include new provisions addressing the relationship between energy retailers and distributors. These provisions include a credit support regime applying to distributors and retailers, which sets out how a distributor must determine a retailer’s credit allowance. A retailer’s credit allowance is based on a number of inputs, including the total annual retailer charges (TARC). TARC is defined as the total annual amount of network charges (distribution service charges for gas distributors) billed by the distributor to all retailers as most recently reported by the distributor to the AER.

Clause 6B.B3.2(b) of the Electricity Rules and Rule 519 of the Gas Rules require distributors to report their TARC to the AER, and the AER to publish the TARC for each distributor on its website. The amendments do not take effect in a participating jurisdiction until the National Energy Retail Law is applied in that jurisdiction. Jurisdictions currently applying the National Energy Retail Law and, therefore, required to report TARC are ACT, Tasmania, South Australia, NSW and Queensland.

TARC for distributors in jurisdictions that have adopted the Retail Law

The most recent Total Annual Retailer Charges (TARC) for each electricity and gas distributor in jurisdictions that have adopted the National Energy Retail Law is available below. The TARC for electricity and gas distributors in other jurisdictions will be published by the AER once the National Energy Retail Law has been applied in those jurisdictions.
