Grid connection delays pose growing legal risks for Australian data centre developers

As electricity demand from the data centre sector continues to surge, pressure on network infrastructure is increasing, as is scrutiny of how new projects secure access to the grid. In New South Wales alone, data centre developers were seeking up to 28 gigawatts (GW) of network capacity as of July 2026, including around 13 GW tied to projects currently in advanced connection discussions.

Leanne Olden, an expert in planning at Pinsent Masons, said: “Developers are increasingly facing the risk that projects can be delayed or disrupted despite obtaining key development and land-use approvals.”

“Connection processes can involve lengthy negotiations with network operators, studies into system impacts, and potentially significant augmentation works before power can be supplied,” she said.

Olden highlighted the growing legal and commercial risks associated with the connection process itself, particularly where delays affect construction schedules, customer contracts and financing arrangements.

“The legal and commercial consequences of delays can be substantial. Failing to meet deadlines can trigger knock-on effects across customer agreements, construction contracts, financing arrangements and lease commitments. In some cases, developers may face claims from customers or counterparties if contractual delivery milestones cannot be met,” Olden said.

Ensuring appropriate community engagement and social licence for any significant augmentation works adds additional risk to these projects and the potential for years’ long delays, as has recently been seen in Victoria, according to Olden.

Proposed NSW reforms seek to ensure that data centre operators fund the infrastructure required to connect to the network, rather than transferring costs or risks to households and smaller businesses. The proposed reforms reflect growing regulatory scrutiny of how data centres connect to the electricity network.

Jim Hunwick, an expert in project finance at Pinsent Masons, said: “This landscape means grid access is a project-wide legal risk rather than a standalone technical issue.”

“Connection milestones, augmentation costs, bank guarantee obligations, renewable energy supply arrangements, firming capacity commitments and delay liabilities should be aligned across project documentation from an early stage,” he said.

“Securing finance at an early stage and negotiating connection agreements with network service providers as soon as possible are key factors in ensuring a data centre project proceeds on time and close to budget.”
