Frequency control work plan

The frequency control work plan forms a key component of AEMO’s ongoing work to prepare and support the changing NEM power system. The development of AEMO’s frequency control work plan aims to facilitate effective communication of technical issues, prioritising the most urgent issues, and allowing them to be addressed in a cohesive way across industry.

There has been a substantial amount of work undertaken across industry in relation to frequency control over recent years, not least within AEMO.

As the pace of change within the energy industry increases, there is a greater need for technical engineering advice to inform our understanding of what changes should be pursued and how urgently they are needed.

While AEMO publishes a range of information on frequency control, there is a need to provide better visibility of AEMO’s ongoing program of technical work and priorities as the system operator.

The release of the frequency control work plan, in September 2020, was to provide immediate visibility on AEMO’s current frequency control work to inform current AEMC and ESB processes. This plan was subsequently updated in March 2021 and again in September 2021.

The frequency control work plan was a recommendation from the Renewable Integration Study (RIS) Stage 1. It forms a core part of AEMO’s ongoing work to prepare and support the changing NEM power system.
