The Wholesale Demand Response Mechanism

The Wholesale Demand Response Mechanism (WDRM) has been created to allow energy users to offer Demand Response (DR) into the wholesale electricity market (and to get paid for doing so). Many businesses across Australia are well-suited to offer DR, and they are seizing this new opportunity to significantly improve their bottom line while supporting a cleaner and more competitive future for Australia. Enel X is the market leader in Demand Response, and it offers a comprehensive service through its Virtual Power Plant (VPP) platform that helps businesses maximise what they can earn from the WDRM.

How does it work?

Grid need

The National Electricity Market (NEM) balances the supply of and demand for electricity in real-time. Depending on this balance, the market produces a different ‘spot’ power price every five minutes of every day. 

When demand is very high relative to the available supply, the spot price will spike, and the Australian Energy Market Operator (AEMO) will typically issue a ‘Lack of Reserves (LOR)’ notice indicating that the power grid is under stress.

VPP is called, customer responds


The WDRM allows qualifying DR resources to offer their energy capacity into the NEM as a new source of power supply during these critical times. This will help AEMO enhance the reliability of the system, while allowing DR providers to earn the spot power price whenever they are utilised.

For DR resources that offer themselves to the market as a last line of defence for the power grid, they can expect to be utilised primarily during summer evenings for only a few dozen hours each year.


Earn regular payments

Customers receive regular payments for when their power is provided to support the grid during a dispatch event.  

Advance Australia’s renewable future

DR allows independent aggregators like Enel X to provide additional, dispatchable capacity to support the grid. This new capacity is essential to supporting the renewable energy transition, because dispatchable resources help to integrate variable renewable energy sources onto the grid.

Our offering

While valuable, the WDRM is going to be quite complex. AEMO requirements will include unique market registrations, dedicated SCADA connections, real-time market bidding and dispatch procedures, and detailed performance measurement and compliance rules.


We approach the WDRM the same way we approach everything we do – with a mission to make it easy for businesses to access this new energy opportunity. To do so, we offer a turnkey service that manages all aspects of WDRM participation.
