AEMO did not submitted a proposed pricing methodology to the AER for a period beyond the expiry of it's approved pricing methodology (1 July 2014 to 30 June 2019) and sought instead to have the approved pricing methodology continue to apply to allow more time to consider the impact on transmission network services and prices of the many recent changes to the way in which electricity is produced, supplied and consumed in the Victorian declared shared network and across the NEM.
In June 2019, AEMO proposed an Undertaking to the AER under section 59A of the National Electricity Law to continue to set prices for shared transmission services in accordance with the terms of the approved pricing methodology for the period 1 July 2014 to 30 June 2019, for the period commencing 1 July 2019 and ending on 30 June 2021. The AER approved AEMO’s proposed Undertaking.
In June 2020, AEMO proposed to extend this Undertaking by an additional year to 30 June 2022. AEMO requested this additional time to conduct stakeholder consultation due to the effects of the COVID-19 pandemic. The AER approved AEMO’s proposed revised Undertaking.
