AER Decision - ElectraNet 2022-23 Inertia Shortfall Cost Pass Through - June 2022

On 30 June 2022, the AER released its decision that, for the purposes of clause 6A.7.3(c) of the National Electricity Rules (NER), the event referred to in ElectraNet’s written statement of 17 February 2022 as a 'positive change event' occurred on 17 December 2020 when the Australian Energy Market Operator published and provided to ElectraNet in accordance with clause 5.20B.3(c) of the NER a notice of an expected inertia shortfall in South Australia in 2022-2023.

On that basis, ElectraNet’s written statement of 17 February 2022 was not submitted within 90 business days of the occurrence of the event referred to as a 'positive change event' in the statement, as required under clause 6A.7.3(c) of the NER. ElectraNet’s written statement is therefore not a valid statement for the purposes of clause 6A.7.3(c) of the NER, and therefore there is no dectermination for the AER to make under clause 6A.7.3(d) of the NER in relation to that statement.

Subject to the requirements of clause 6A.7.2 of the NER, ElectraNet will be able to recover costs efficiently incurred to provide inertia network services in 2022-23 under annual network support cost pass through arrangements.
