Enervest last week announced its acquisition of the Northern Border Battery, a 300 MW large-scale Battery Energy Storage System in development, to be located on the Bruxner Highway, about 16 kilometres south of Bonshaw and about 80 kilometres north of Inverell.

With Australia’s largest coal-fired power station, Eraring, set to close in April 2029 and more than 27 GW of grid-scale storage projected to be required by 2030, Enervest  says the Northern Border Battery will be critical infrastructure for safeguarding system reliability, flexibility and security through the energy transition.

The project will be one of the first assets retained under Enervest Group’s own-and-operate model, further strengthening Enervest’s presence in Australia’s rapidly growing energy storage sector and complementing its existing portfolio of utility scale and sub-five MW projects across the National Electricity Market.

Strategically located on the New South Wales-Queensland border, the NBB connects into the Dumaresq substation and holds development approval for a 300 MW BESS.

The project is currently advancing through the connection application process with Transgrid and Australian Energy Market Operator.

Early works have commenced with site access and public intersection upgrades completed.

Construction of the BESS facility is expected to commence in early 2028.

Enervest CEO, Ross Warby said the acquisition of the Northern Border Battery represents a very significant milestone in Enervest’s long-term own-and-operate strategy.

“It underscores our focus on attractive, high quality, investible projects that deliver lasting benefits. With a strong foundation established, we’re now delivering this project at pace to enhance grid resilience and support the next phase of the National Electricity Market as legacy generation exits the system,” Mr Warby said.

“Community is at the heart of everything we do and we’re looking forward to listening to, and working closely with, Indigenous communities, local councils, and community groups to ensure the Enervest Northern Border Battery delivers lasting social, economic, and cultural outcomes for the region.”
