Transgrid Flags Infrastructure Pressures as Data Centre Demand Grows in New South Wales

Summary

• Transgrid and water sector bodies have highlighted rising infrastructure pressures linked to growing data centre demand in New South Wales.
• Utilities report a surge in connection enquiries from large-scale data centre projects.
• Policymakers are reviewing how to balance digital infrastructure growth with energy, water, and cost considerations.

SYDNEY, April 10, 2026 — Energy and water authorities in New South Wales have raised concerns about the infrastructure implications of rapidly expanding data centre development, as part of submissions to an ongoing parliamentary review.

Rising Demand for Power Infrastructure

Transgrid, the state’s transmission network operator, indicated that it has received a significant increase in enquiries and applications from data centre developers seeking grid connections in recent years.

Large-scale facilities, particularly those supporting artificial intelligence and cloud computing workloads, require substantial and continuous electricity supply, placing additional demands on transmission and distribution networks.

Utilities note that meeting this demand may require upgrades to grid infrastructure, including substations and transmission lines, depending on project scale and location.

Water Use Considerations

Water sector organisations, including Water Services Association of Australia, have also highlighted the potential impact of data centre cooling systems on local water resources.

Some cooling methods rely on significant water usage, prompting calls for careful planning, especially in regions prone to drought or water stress. Industry groups have encouraged consideration of alternative cooling technologies and sustainable water sourcing options.

Policy and Planning Review

The Parliament of New South Wales is currently examining how best to manage the growth of data centres within existing planning and infrastructure frameworks.

Discussions include potential measures to ensure that large projects contribute appropriately to the infrastructure they require, as well as strategies to align development with energy availability and environmental considerations.

Government officials have acknowledged the importance of data centres to the digital economy while emphasizing the need for balanced, sustainable growth.

Why this matters

• Infrastructure Planning: Rapid data centre growth is increasing demand on electricity and water systems.
• Cost Allocation: Policymakers are assessing how infrastructure upgrade costs should be distributed.
• Sustainable Growth: Balancing digital expansion with resource management is becoming a key policy priority.

FAQs

Q1. Why do data centres require so much electricity?

They operate large numbers of servers continuously, especially for AI and cloud services, leading to high and constant power demand.

Q2. Do data centres affect household utility bills?

Potential impacts depend on regulatory frameworks and how infrastructure costs are allocated among users.

Q3. Why is water usage a concern?

Some cooling systems use significant amounts of water, which can be challenging in water-scarce regions.
