Major reforms in the National Electricity Market

Major reforms will be introduced in the National Electricity Market (NEM), improving market efficiency, competition and consumer benefits.

Years in the making, the reforms will help the energy transition to benefit Australian consumers. They include 5 Minute Settlements (5MS), Wholesale Demand Response (WDR) and 2-day retail switching.

These reforms are the culmination of rule changes, innovative digital systems and extensive stakeholder engagement and partnership.

Daniel Westerman, CEO of the Australian Energy Market Operator (AEMO) said the reforms will create better outcomes for market participants, consumers and a more efficient energy sector.

‘From 1 October, 5MS will reduce the wholesale electricity spot market settlement period from 30 minutes to 5 minutes, matching the electricity dispatch periods,’ Mr Westerman said.

‘5MS provides better price signal for investment in fast response and flexible technologies, such as batteries and gas-peaking generation.’

At the start of October, the time for consumers to change electricity retailers will reduce from up to 3 months to 2-day transfers. Following a recommendation in the ACCC’s Retail Electricity Pricing Inquiry report, AEMO developed a new framework to facilitate faster and efficient switching.

WDR will be available from 24 October 2021. This will enable large commercial and industrial businesses to bid and schedule a reduction in electricity consumption for payment. A new market participant category will be introduced to coordinate and offer ‘demand response’ into the NEM.
