Port of Newcastle (PON) has become the first port in NSW approved to safely store grid-scale lithium-ion batteries at its Mayfield multipurpose terminal.
The approval strengthens the port's position as the state's leading logistics gateway for renewable energy infrastructure.
"This isn't just a milestone for Port of Newcastle - it's yet another way we're helping customers deliver the infrastructure NSW needs to support a more diverse energy mix," port chief executive Craig Carmody said.
"These are complex cargoes that require specialist handling, purpose-built infrastructure and the right safety systems. We've invested in that capability because we see where the market is heading and what our customers will need.
The approval for battery storage, granted by the NSW government in late 2025, has enabled the port to receive and store batteries destined for three of the state's largest battery projects - AGL's Tomago Battery, Origin Energy's Eraring Battery, and Bellambi Heights Battery Energy Storage System.
Together, the projects represent about 1.7 gigawatts of dispatchable capacity and 6.8 gigawatt hours of energy storage, enough stored electricity to power more than a million homes for four hours during periods of peak demand.
"Whether it's wind turbine components, grid-scale batteries or other major project cargo, Port of Newcastle has built a reputation for handling complex logistics safely, efficiently and reliably. That's why project owners continue choosing to bring this cargo through Newcastle," Mr Carmody said.
The battery storage capability builds on the port's established role handling oversized renewable energy cargo, including wind turbine components for projects across NSW.
Demand for the capability has grown rapidly, with the port regularly receiving battery shipments for projects across its catchment while continuing to handle wind energy components supporting renewable energy developments throughout NSW.
The port is investing in expanded infrastructure at its multipurpose terminal, including the $36 million berth extension project to accommodate larger vessels. It is also exploring increasing capacity for project cargo and battery storage.
The investments are part of the port's broader diversification strategy, a bid to strengthen its ability to support emerging industries while maintaining its position as Australia's largest coal export port and a critical trade gateway for traditional bulk commodities including coal and grain.
AGL chief operations and construction officer Matthew Currie said the company's grid-scale battery fleet was growing rapidly, and the 500 megawatt Tomago Battery is expected to be operational in the second half of 2027.
"Grid-scale batteries are critical to Australia's energy transition, supporting reliability and stability by dispatching energy when customers and the grid need it," he said.
"As we prepare for the installation of more than 400 lithium-ion battery units to form the Tomago Battery, the ability to safely receive and temporarily store battery units and other components at the Port of Newcastle is providing important flexibility for our project team."
