Dunedoo Energy Project
Project overview
Located around 2 km north of Dunedoo within the Warrumbungle Shire local government area, this site is set to become the home of the Dunedoo Energy Project – a 55 MW solar farm supported by a 60 MW Battery Energy Storage System (BESS).
About the project
Originally owned by Ib Vogt GMBH, this State Significant Development (SSD) was acquired with an existing Development Application approval by Flow Power at the end of 2025. This marks an exciting milestone in our growing portfolio of renewable energy assets.
Flow Power will build, own and operate the Dunedoo Energy Project, with construction scheduled to begin in late 2026. One complete, the project will feature approximately 173,000 solar panels across 92 hectares and connect to Essential Energy’s existing Dunedoo Substation via a new 66 kV transmission line, supported by planned substation upgrades.
Current Statutory approvals for the development, including the Development Consent, Environmental Impact Statement, and any post-approval documentation such as approved plans and staging plans can be found on the NSW Planning Portal via the button below.
About the land
The site, currently used for agricultural purposes, is located within the Warrumbungle Shire Council. The Traditional Owners of this area are the Mowgee and Dabee people of the Wiradjuri Nation, and the Kamilaroi/Gomeroi peoples of the Kamilaroi Nation.
A draft Aboriginal Cultural Heritage Assessment and Heritage Management Plan has been developed in consultation with First Nations representatives and other stakeholders to minimise impacts to heritage items during Stage 1 works. We look forward to continuing our collaboration to ensure all commitments in the plan are delivered.
How will the project work?
Similar to other combined solar and battery projects (such as our projects in Berri and Newstead), the solar and battery storage system work together to generate and store clean energy.
The solar panels capture energy from the sun during daylight hours, and supply this to the grid. If there is excess electricity generated, this will be stored in the battery. The battery will then discharge this energy when demand is high on the grid – typically during morning and evening peaks – helping reduce demand strain and drive down prices for New South Wales.
Once operational, the Dunedoo Energy Project will contribute to cleaner energy generation and help reduce carbon emissions across the grid.
The project supports more affordable energy outcomes for consumers by adding new renewable supply when it’s needed most, increasing competition in the market and reducing the influence of large generators. This helps to keep prices lower.
With its integrated battery system, the project can rapidly deliver energy during peak demand or outages, strengthening reliability across the network.
Flow Power is committed to engaging local workers, businesses, and contractors wherever possible, ensuring the project delivers meaningful benefits to the Dunedoo community.
FAQ
Stage 1 construction works are scheduled to begin in the second half of 2026. This will include landscaping works within the solar farm site and upgrades to the road. The road upgrades will improve the intersection of Castlereagh Highway and All Weather Road, facilitate heavy vehicle access to the site and include the construction of a passing bay along All Weather Road.
Once these works are complete, Stage 2 (full construction) will commence and is anticipated to last approximately 12 months. This will include the full construction including the solar farm and battery infrastructure, transmission line and connection works in the Essential Energy Dunedoo substation. It’s anticipated this will commence by the end of 2026.
We will continue to engage with local stakeholders to share updates and answer any questions throughout the project’s development.
The Dunedoo Energy Project is expected to generate for approximately 30 years.
Yes. All infrastructure will be removed at the end of the project’s life as part of a planned decommissioning process.
We anticipate the project could create up to 125 construction jobs and 3 full-time operational jobs.
Prior to commencing construction, Flow Power will prepare an Accommodation and Employment Strategy for the development in consultation with Council, and to the satisfaction of the Secretary. This strategy will:
- propose measures to ensure there is sufficient accommodation for the workforce associated with the development;
- consider the cumulative impacts associated with other State significant developments in the area and tourism activity;
- investigate options for prioritising the employment of local workers for the construction and operation of the development, where feasible; and
- include a program to monitor and review the effectiveness of the strategy over the life of the development, including regular monitoring and review during construction.
Its proximity to the Essential Energy substation and high-voltage transmission lines makes it ideal for connecting renewable energy to the grid.
