Background

The Australian Energy Market Commission writes Australia's National Electricity Rules. It is not the market operator: that role belongs to the Australian Energy Market Operator (AEMO), a separate body responsible for running the market day to day.

On 5 August 2026 the AEMC advised federal and state energy ministers that data centres should surrender Renewable Electricity Guarantee of Origin certificates sourced from new wind and solar capacity, prove new demand is backed by new firm generation, register directly as market participants, and accept connection terms that reward shifting load away from peak periods. The advice avoids requiring hour-by-hour matching of consumption to renewable generation, splitting the year into peak and off-peak periods instead; the commission said this deliberately avoids "the complexity of hourly load matching." The AEMC has also stressed that market registration does not require market participation, since large loads already sit inside settlement indirectly as retailer customers.

A final AEMC determination on the technical access standards behind this advice is due in late October 2026.

Common Questions
What did the AEMC tell energy ministers about data centres?
On 5 August 2026 the AEMC advised that data centres should surrender REGO certificates against consumption, prove new demand is backed by new firm capacity, register as market participants, and accept demand-shifting connection terms.Source: AEMC
Is the AEMC the same as AEMO?
No. The AEMC writes Australia's national electricity market rules; the Australian Energy Market Operator (AEMO) runs the market day to day.
Do Australian data centres have to match renewable energy use hour by hour?
No. The AEMC's REGO proposal explicitly avoids hourly matching, splitting compliance into broad peak and off-peak periods settled annually after the fact.Source: AEMC Detailed Policy Assessment
When will Australia finalise its data-centre grid access rules?
The AEMC's final determination on technical access standards is due in late October 2026.Source: AEMC
