Australia’s electricity grid is set for a monumental challenge, with new data from the Australian Energy Market Operator (AEMO) revealing that demand from data centres is projected to increase almost seven-fold by 2035-36. This significant surge, outlined in AEMO’s 2026 Electricity Statement of Opportunities (ESOO) report released this week, forecasts data centres will account for 13 per cent of the National Electricity Market (NEM) power consumption within the next decade, up from approximately three per cent today.
The AEMO report, published on Tuesday, 25 August 2026, highlights the profound impact of artificial intelligence (AI) adoption and expanding cloud services on the nation’s energy infrastructure. It projects data centre electricity usage in the NEM to skyrocket from around five terawatt-hours (TWh) currently to an estimated 34 TWh by 2035-36.
This rapid growth poses substantial implications for grid planning, reliability, and ultimately, the electricity bills of Australian households and businesses. The report underscores the urgency for timely investment in new generation, storage, and transmission infrastructure to meet this escalating demand while simultaneously managing the retirement of ageing coal-fired power plants.
Unprecedented Demand Growth From Digital Infrastructure
AEMO’s 2026 ESOO, an annual 10-year reliability outlook for electricity supply and demand across Australia’s eastern and south-eastern states and territories, identifies 225 known data centre projects across the country. The market operator notes that data centres are becoming an increasingly significant driver of electricity demand, particularly in New South Wales and Victoria, where the concentration of development is projected to be greatest.
“Rapid growth in data centres, driven by increased artificial intelligence (AI) adoption and cloud services, remains one of the most significant sources of forecast growth and uncertainty as a strong pipeline of projects is evident in grid connection enquiries,” AEMO stated in its report.
Despite the improved reliability outlook for the NEM overall, with no forecast reliability gaps identified before 2030 due to a record pipeline of new generation and storage, the sheer scale of data centre demand presents a new frontier for energy planners. The report indicates that approximately 9.1 gigawatts (GW) of new energy generation and storage reached full output in 2025-26 alone, doubling the previous year’s additions. However, this impressive build-out must continue at pace to keep up with both electrification and the digital surge.
Federal and State Responses to the Digital Energy Challenge
The federal government is already responding to this emerging challenge. Prime Minister Anthony Albanese is scheduled to meet with state and territory leaders this week to discuss proposed national controls for data centres. Under these proposed obligations, new data centre developments would be required to include clean energy generation or storage to offset their demand and contribute to the cost of electricity transmission and distribution infrastructure.
This approach aims to ensure that the burgeoning digital economy supports, rather than strains, Australia’s transition to a decarbonised grid. States are also developing their own frameworks. For instance, the New South Wales government, on 24 August 2026, released a consultation paper proposing reforms to electricity network connection and cost recovery arrangements for data centres. These include an entry bond of $30,000 per megawatt (MW) for connection applicants and a Major Network Upgrade Fee of $200,000/MW in the Sydney-Newcastle-Wollongong area.
Such measures are crucial to manage the significant capital expenditure required for grid upgrades. The increasing demand also highlights the value of demand-side management and consumer energy resources in maintaining grid stability. Homeowners with solar and battery systems, for example, can play a vital role by participating in Virtual Power Plants (VPPs) to help balance supply and demand.

The Role of Transmission and Storage
Meeting the combined growth in general electricity consumption (forecast to increase by over 40% over the next decade due to electrification) and data centre demand necessitates substantial investment in transmission infrastructure. Projects like EnergyConnect, Australia’s largest transmission project, which recently saw its New South Wales section fully energised, are critical. AEMO is expected to commence inter-network testing on the second stage of EnergyConnect later in 2026 to confirm the reliability and performance of this new infrastructure linking NSW, Victoria, and South Australia.
Furthermore, the integration of new renewable generation and storage is paramount. The ESOO report reinforces that the successful delivery and operational availability of these projects are key to replacing retiring coal-fired generation and meeting growing electricity demand.
| Demand Source | Current (2025-26) | Projected (2035-36) | Growth Factor |
|---|---|---|---|
| Data Centre Consumption | 5 TWh | 34 TWh | 6.8x |
| Share of NEM Demand | 3% | 13% | 4.3x |

Households and businesses are increasingly leveraging technologies like smart energy monitoring systems and home batteries to manage their own consumption and contribute to grid stability.

The challenges outlined in AEMO’s latest ESOO are clear: Australia’s energy system must evolve rapidly to accommodate the digital revolution. Successful navigation of this transformation will depend on coordinated policy, strategic infrastructure investment, and the continued integration of consumer energy resources.
