On 4 June 2020, the AEMC received a rule change request from Delta Electricity which seeks to amend the National Electricity Rules to introduce an ex-ante, day ahead capacity commitment mechanism and payment for essential system services (ESS).

The Commission is considering the Delta Electricity rule change request in conjunction with a rule change request submitted by Hydro Tasmania on 19 November 2019. The Hydro Tasmania rule change request aims to create a market for “synchronous services” including inertia, voltage control and fault level/system strength.

The Delta Electricity Capacity commitment mechanism for system security and reliability rule change request (ERC0306) and the Hydro Tasmania Synchronous services market rule change request (ERC0290) were consolidated on 2 February 2022. The consolidated rule change request will be addressed under the combined process with the updated name “Operational security mechanism” (ERC0290). The Commission considers that both rule change requests seek to address the same issue of the provision of ESS as the proportion of variable renewable energy (VRE) increases, and consolidation will allow for coordinated consideration of the issues.

A link to the consolidated rule change request is here. This contains all information and documents relating to both rule change requests, including a directions paper released on 9 September 2021.

The AEMC plans to publish a consolidated draft determination on 30 June 2021.
