Australia’s NSW becomes first state to detail national data centre rules with new framework

Announced on 17 August, the NSW Data Centre Policy Framework is built around three pillars that the government describes as world-leading in bringing together energy, water and environmental considerations within a single policy document.

The government said the framework reflects a balanced and evidence-based approach intended to support continued investment in NSW while protecting the interests of households, businesses and communities, and that it implements the Australian government’s Expectations of Data Centres and AI Infrastructure Developers, published in March 2026.

NSW Treasurer Daniel Mookhey said data centre investment in the state has grown by around 75% per year on average over the three years to December 2025, a pace of growth the government credits as one reason the state economy has avoided recession.

There are 19 data centre projects worth AU$50.3 billion (US$32.9 billion) currently in the State Significant Development pipeline, on top of more than 60 facilities already operating or under construction.

Inside the three pillars

The first pillar, the NSW Data Centre Guidelines, sets out performance measures built around six principles.

These require developers to apply world-class environmental and efficiency standards, impose no net cost on consumers and communities, fund the additional water and energy supply their projects need, enhance local community infrastructure and amenities, invest in future industries across the supply chain, and demonstrate a commitment to training and skills that support jobs.

Data centre proponents that meet the performance measures tied to these six principles qualify for an assessment commitment of 75 days, while still being required to meet all standard planning, environmental and community consultation requirements.

That commitment is supported by parallel changes to Independent Planning Commission processes intended to further streamline assessment of major projects, and the state’s newly established Investment Delivery Authority will convene an industry collaboration event to connect energy and data centre investors.

The Guidelines will be reviewed annually, or sooner if required, to keep pace with changes in the industry and its operating environment.

The second pillar addresses energy infrastructure cost recovery. The framework document states plainly that data centre electricity demand growth is forecast to drive the need for new and accelerated transmission upgrades, and that current regulatory frameworks do not account for this, creating a risk that costs could be passed on to other energy users without reform.

The government has introduced legislation to enable regulatory changes that would ensure data centres, rather than households and small businesses, bear the costs and risks of the additional energy infrastructure required for their connections.

Beyond cost recovery, the reforms are also intended to enable the government to develop new access scheme arrangements to proactively manage growth in data centre demand while continuing to support the broader energy transition, with interim commercial arrangements remaining in place to support investment until the longer-term reforms are finalised.

Public consultation on the detailed implementation of these energy reforms began on the day of the announcement.

The third pillar commissions the Independent Pricing and Regulatory Tribunal (IPART) to review the water pricing framework applied to data centre customers.

The policy framework notes that current water pricing arrangements do not adequately account for the full cost of servicing data centres, which the government says are more expensive to service than other customer classes because of the larger volumes of water they require, their higher reliability requirements, and their proximity to available water resources.

The review will examine how pricing can be adjusted to reflect these costs fairly while continuing to support investment and growth, and while promoting efficient water use and protecting long-term water security for other communities and businesses. As with the energy reforms, interim commercial arrangements will continue to apply while longer-term water pricing arrangements are developed.

Alongside the three pillars, the government is establishing an Industry Advisory Forum to provide ongoing engagement as technologies and market conditions evolve, and says it will continue to engage with the federal government and other states and territories to support a nationally harmonised approach.

The framework document emphasises several key commitments. These include exploring options to support renewable-energy-derived fuels for backup diesel generators and alternative backup power sources. It also involves refining environmental performance standards within the sector and updating water and energy cost recovery frameworks as regulatory changes and reviews progress.

Additionally, the document outlines the need to facilitate the alignment of wind generation and grid-scale storage with data centre customers for offtake agreements. There is a focus on developing a coordinated approach to forecasting data centre demand to support unified infrastructure planning.

Furthermore, it calls for the creation of a model for skills and training centres of excellence and the establishment of a shared vision for local content and procurement requirements.

A new Office of AI has also been established within the Cabinet Office to coordinate the government’s broader response to the opportunities and challenges of artificial intelligence, working alongside Digital NSW and public sector unions.

Part of a wider national framework taking shape

The NSW framework builds on commitments Prime Minister Anthony Albanese announced in July, when he said large-scale data centres would be legally required to become net generators of renewable energy rather than net consumers, underwriting new wind, solar and firming capacity to cover their own demand.

That announcement converted a set of voluntary government expectations, published in March, into a binding regulatory direction, with national legislation targeted for introduction to Parliament in early 2027.

Under the proposed national rules, large data centres would also be required to pay their full share of grid connection costs and reduce power use when the grid is under strain, principles that the NSW framework’s second pillar now gives detailed regulatory form at the state level.

Federal energy minister Chris Bowen has since clarified how state and national rules will interact.

Speaking at the National Press Club earlier this month, Bowen said states are free to impose more rigorous requirements than the national minimum but cannot weaken it, a position aimed squarely at Queensland and the Northern Territory, which had broken from the other six states and territories in opposing the nationally consistent approach at a ministerial council meeting in July.

Bowen said the federal government would use its powers over the Australian Energy Market Operator (AEMO) and the Australian Energy Market Commission (AEMC) to prevent dissenting jurisdictions from allowing large data centres to connect on terms inconsistent with the national floor.

The AEMC has separately been developing the technical architecture for how data centres connect to the grid.

Its proposals, alongside legislation NSW introduced earlier this year that gives the state energy minister the power to control grid access for large loads, form part of the same regulatory picture that the new framework’s second pillar now builds on, formalising cost-recovery mechanisms for the network upgrades that loads of this scale require.

AEMO has forecast that data centres will account for around 10% of total National Electricity Market (NEM) demand by 2050, up from approximately 2% today, a trajectory that has sharpened the urgency of finalising these policy settings before the announced project pipeline converts into operational load.
