From consumers to prosumers: how Australia plans to align data centres with the energy transition

Australia’s proposed framework would require large data centres to underwrite new clean power and provide demand flexibility, pushing them from energy consumers to grid‑supporting 'prosumers', while states like New South Wales (NSW) move faster with concrete, additionality‑focused rules.

The rapid rise in demand for AI and compute has led to a dramatic increase in data centre investment, both in Australia and globally, with Australia attracting 6.7 billion USD in 2024 alone, second behind the US. Australia is one of the most attractive markets in the region, as demonstrated in a recent market scan shown below.

Global investment in the sector exceeded 270 billion USD in foreign direct investment in 2025, representing more than one-fifth of all global greenfield investment. However, this rapid build-out is straining electricity systems. Data centres can be developed and energized faster than new transmission or large-scale renewables, creating a timing gap that leans on existing capacity.

In 2025, data centre electricity demand rose by 17%, far outpacing global electricity demand growth of 3%. In Australia, data centre load on the National Electricity Market could jump from ~2% now to ~10% in 10 years, with demand rising from ~300 MW in the 2024–2025 period to as much as 3.2 GW by the mid-2030s. Modelling cited in a Clean Energy Finance Corporation (CEFC) commissioned Baringa report suggests wholesale price impacts will largely depend on how quickly new renewables and storage are built alongside data centre growth.

What the Commonwealth has proposed

In March, the Australian Government published “Expectations of data centres and AI infrastructure developers”, outlining five national expectations across the national interest, energy, water, skills, and innovation for new or expanded large-scale facilities (co‑lo, hyperscale, and AI centres), excluding small edge or on‑premise enterprise sites.

Shortly after, in July, the federal government proposed a national framework for large-scale AI data centres that would:

• Require future large facilities to offset their electricity demand with new generation, particularly renewables, and to contribute to grid augmentation costs.
• Encourage centres to contribute as much power to the grid as they consume over time, shifting them from pure consumers to net 'prosumers'.
• Impose obligations to minimize water use, fund any additional water infrastructure required, maximize energy efficiency and demand flexibility, and participate in a centralized fast‑track approvals pathway in exchange for compliance.

The goal of this new proposed framework is for data centre growth to continue, but that any new builds do not increase energy prices for other users and that they contribute positively to the energy transition.

The framework draws on four key recommendations made by the Australian Energy Market Commission (AEMC):

• Offset with clean energy – Surrender Renewable Electricity Guarantee of Origin (REGO) certificates from new, additional generators to match power used.
• Back demand with firm capacity – Show new capacity backs their load, so connecting doesn't strain supply-demand balance or raise wholesale prices.
• Register as market participants – Become registered participants, subject to market rules.
• Stay flexible – engage in demand shifting and co-location with generation to ease network pressure.

The AEMC also recommended staging and scaling measures, with tighter technical obligations expected for facilities above ~30 MW. Additionally, to manage the timing gap between a data centre's connection and new renewable generation coming online, the advice also identified options for data centres to temporarily draw on existing renewables and make up any shortfall by surrendering additional certificates in later years.

The government has signalled an intention to introduce legislation in early 2027, with a willingness to override inconsistent state and territory approaches, if necessary.

States are diverging

But the proposed federal framework is just that, a framework, and states are already choosing their own paths.

New South Wales, with the highest share of data centre consumption, has moved ahead of other states with a detailed data centre policy framework and guidelines that offer a streamlined planning pathway. But the devil is in the detail, particularly technology requirements with minimum offtake and storage.

By contrast, Queensland and the Northern Territory have opposed any mandatory renewable energy pairing requirement for data centres. Queensland prefers that data centres source electricity on a competitive basis, explicitly including gas, and has publicly resisted a 100% new‑additional‑renewables mandate, citing concerns about investment economics and potential price impacts.

What this means for data centres

• Shift from certificates to additionality. Large data centres will increasingly be expected to underwrite new renewable generation and firming, rather than rely on existing certificates or short‑term contracts.
• Long‑term contracting. Operators will need long‑dated PPAs and firming arrangements that match or exceed their load profiles, often in the same jurisdiction, and demonstrate they enabled new projects to reach Final Investment Decision (FID).
• Market participation and flexibility. Registration, demand response, and potentially co‑location with generation or storage becoming strategic levers for both cost and compliance.
• Siting and timing matter. Locating near renewable energy zones, transmission capacity, or behind‑the‑meter opportunities may lower risk. Timing gaps between load and new supply remain a central execution risk.

What this means for other large data consumers

The proposed framework aims to let data centre growth continue without lifting prices for other users, while accelerating new renewable energy supply. In the short term, certificate markets may tighten, with demand for REGOs (and, to 2030, Large-scale Generation Certificates (LGCs)) potentially rising faster than new projects reach the Commercial Operation Date (COD), pushing prices up. Over time, if the rules truly drive additional build, expanding renewable and storage supply could ease that pressure.

This likely means:

• Tighter certificate markets. Prices are currently at historical lows, and voluntary purchases have been rising as large users take advantage. See figure below.
• Higher grid fees for grid augmentation to meet rising demand.
• More competition for long‑dated PPAs and firming, with higher premiums for shaped or round‑the‑clock products.
• Longer or more uncertain connection timelines for PPA projects where transmission is constrained
• A growing system-wide electricity cost advantage driven by flexible loads and portfolios that integrate wind, solar, and storage, as well as behind-the-meter solutions.
• Potential moderation of peak prices if prosumer data centres add firm capacity and participate in demand response

Open questions

1. How 'new and additional' will be defined and verified under REGO, and how bridging provisions for temporary shortfalls will work in practice.
2. The treatment of firming (technology types, duration requirements, emissions intensity) and how costs are allocated.
3. Whether Commonwealth legislation will harmonize or override diverging state approaches.
4. The net impact on wholesale / futures electricity and grid prices.

Bottom line

Australia wants to guide large data centres toward becoming prosumers that help finance and firm new clean generation. As shown in the Australian Energy Market Operator´s (AEMO’s) latest Statement of Opportunities report, much of the NEM’s coal generation is exiting the market in the next 10 years, and will be replaced by utility storage, utility solar, and wind. However, growing demand from data centres, without guardrails, will put pressure on the grid and its users. Therefore, this framework will also serve as an example for the wider industry to follow, that the requirements are moving from short‑term green credentials to long‑term additionality, flexibility, and market participation. For policymakers and communities, the test will be whether this accelerates the energy transition even further without pushing up prices.
