Australian Energy Market Commission to Expand Wholesale Demand Response Mechanism (WDRM) to Large Industrial Customers

Strategic Insights -

The Australian Energy Market Commission (AEMC) has released a final report on the Wholesale Demand Response Mechanism (WDRM), recommending that the mechanism should continue to operate in the National Electricity Market (NEM). The report suggests that the WDRM has been a worthwhile exercise, resulting in $5.75 million in benefits to date, which is greater than its operational costs. The AEMC plans to initiate a rule change in the first half of 2026 to assess whether sites with multiple connection points should be allowed to participate in the mechanism, which could increase participation in the WDRM and deliver additional benefits.

Key Takeaways:

  • The AEMC plans to expand the WDRM to large industrial customers, including energy-sucking data centers, with the potential to increase participation in the WDRM and deliver additional benefits.
  • The WDRM has resulted in $5.75 million in benefits to date, which is greater than its operational costs, with an additional 237 MWh of dispatch.
  • The AEMC recommends that small customer participation in the WDRM should not be prioritized due to substantial complexities that need to be addressed.
  • The WDRM is the only market mechanism in the NEM that facilitates payment for reducing load against a baseline and allows non-financially responsible market participants to participate in the electricity market.
  • Enel X managing director of Australia-New Zealand, Carl Hutchinson, sees the AEMC's decision as a great confirmation of the important role that the WDRM plays and believes it can continue to evolve with the initiation of the requested rule change process.

Statistics:

  • 74 megawatts (MW) of registered capacity when the review began.
  • 150 MW of total registered capacity after doubling, with an additional 76 MW reaching participation.
  • 10 GW of new transmission-level data center connections estimated by AusNet.
  • $5.75 million in benefits to date resulting from the WDRM.
  • 237 MWh of additional dispatch captured in the analysis extended to June 2025.
  • 300MW of flexible demand estimated to be currently restricted from WDRM participation, with potential to expand by hundreds of megawatts.
