The CEC invites sponsoring and corporate members and key local and international experts and representatives from electricity market institutions to attend a workshop to focus on frequency control in the National Electricity Market (NEM).

Presentations now available

The following presentations from the workshop are available to download.


The workshop will be a deep dive into frequency control in the National Electricity Market. It will look closely at the pros and cons of the current arrangements, highlighting major flaws and opportunities for improvement that encompass the latest and emerging technologies.

The frequency control regime in the NEM has been gaining increasing attention. Dramatic increases in costs for generators and ultimately customers are just the tip of the iceberg. A significant and growing body of evidence is revealing that the regime is not delivering outcomes that are efficient or in the interests of power system security.

Some of the issues to be discussed at the workshop include:

  • Market signals that have not delivered new frequency control capability, but have led to an intervention from the Australian Energy Market Operator.
  • Causer-pays factors that are not representative of the actual impact that generators have on frequency.
  • The impact of significant long-term errors in the integration of wind energy forecasts into the frequency control regime.
  • Identification and solution to potential threats to power system security due to incentives created for relaxed frequency control parameters in synchronous generators.
  • The source and impact of dramatic cost increases for market participants over the last year.

However, this list is not exhaustive.

The existing regime has clearly not created a sound base from which to develop and deploy new innovative technologies such as fast frequency response from inverter-based technologies such as solar PV and battery storage, or wind generation.

The workshop will provide an opportunity to hear about and discuss these issues and more from local and international experts on the major flaws and opportunities for improvement needed to remove barriers to new technologies providing frequency services in the NEM.

More importantly the workshop will create a sound platform for the CEC and members to understand the real challenges that a redesigned frequency control regime would need to address in order to enable these new technologies. The workshop will be chaired by the CEC and the options for advocacy and promoting reform to deliver on this will be considered and discussed at and following the workshop.
