Why is Neoen building the Culcairn battery project?

Neoen is building this project to establish its first "behind the meter" system that operates in direct coordination with an adjacent solar farm.

What are the main capacity numbers for the Neoen facility?

The facility being built by Neoen will feature a 215-megawatt battery system. The company stated that the site will deliver a total storage capacity of 963 megawatt-hours once fully built.

What engineering companies are managing construction for Neoen?

Neoen has appointed a consortium consisting of Taiwan-based NHOA Energy and a joint venture between Equans Solar & Storage and Bouygues Construction to lead the work.

What is the project timeline for the Neoen battery asset?

Neoen expects the Culcairn battery storage asset to become operational in 2028. The company stated that the project will begin supplying power to the electrical grid by this target date.

How does this project impact the broader geographic market for Neoen?

This project expands the renewable footprint of Neoen in the Riverina region of New South Wales. The facility adds to a broader national expansion of grid-scale energy storage assets across regional Australia.

French developer Neoen has commenced construction on a 215-megawatt battery energy storage facility in the Riverina region of New South Wales.
The project represents Neoen’s first "behind the metre" installation designed to operate in direct coordination with an adjacent solar farm.
The project aims to expand domestic grid-scale storage capacity to support regional energy infrastructure by its target delivery date.

French renewable energy developer Neoen has commenced construction on a 215-megawatt battery system with 963 megawatt-hours of storage capacity at its Culcairn solar farm in New South Wales.

The project marks the company's first asset configured to run "behind the metre" in close coordination with a co-located solar installation.

The construction phase will be managed by a consortium consisting of Taiwan-based NHOA Energy alongside a joint venture between Equans Solar & Storage and Bouygues Construction.

The company stated that the storage asset is scheduled to become operational and supply power to the electrical grid in 2028.

The facility adds to a broader national expansion of grid-scale energy storage assets across regional Australia.

The project owner is controlled by global asset manager Brookfield, which continues to grow its renewable energy development footprint across the domestic utility market.
