General enquiries - AEMO determination
AER reference: 


As part of its functions, the Australian Energy Market Operator (AEMO) is a Victorian electricity transmission network service provider. Its next five-year (2022-27) regulatory control period commences on 1 July 2022 to 30 June 2027. Under the National Electricity Rules, AEMO is required to submit its 2022-27 proposed pricing methodology as and when required by the AER.

On 1 April 2014, the AER made its final decision approving a pricing methodology and negotiating framework for AEMO's 2014-19 regulatory control period and specifying a negotiated transmission service criteria.

On 12 June 2019, AEMO submitted an Undertaking to the AER under section 59A of the National Electricity Law to continue to set prices for shared transmission services as per the pricing methodology already approved for the period 1 July 2014 to 30 June 2019. This would allow AEMO 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 National Energy Market. The AER approved AEMO’s proposed Undertaking to apply to 30 June 2021. In June 2020, AEMO proposed to extend this Undertaking by an additional year due to the disruption caused by COVID-19. Consistent with the Undertaking the approved pricing methodology for the 2014-19 regulatory control period will apply until 30 June 2022.

On 19 April 2021, AEMO submitted its proposed pricing methodology to the AER for the 2022-27 regulatory control period.

On 12 October 2021, we released our draft decision on AEMO's transmission revenue determination for the 2022-27 period.
