Spark Renewables Wins NSW Approval for 800 MW Dinawan Solar Farm with 1,574 MWh Battery Storage – EQ
In Short : Spark Renewables has secured planning approval for the 800 MW Dinawan Solar Farm in New South Wales, featuring a 356 MW / 1,574 MWh battery energy storage system. The hybrid project forms part of the Dinawan Energy Hub in the South West Renewable Energy Zone and aims to deliver large-scale dispatchable renewable power to Australia’s grid. ([Renew Economy][1])
In Detail : Spark Renewables has received approval from the New South Wales Independent Planning Commission for its large-scale Dinawan Solar Farm, marking a major milestone for renewable energy development in Australia. The project combines an 800 MW solar installation with a 356 MW battery energy storage system capable of delivering 1,574 MWh, enabling dispatchable renewable power and improved grid reliability. The approval follows detailed assessment and review under state planning regulations. ([Renew Economy][1])
The Dinawan Solar Farm is located in the Riverina region within the South West Renewable Energy Zone, an area identified for large-scale clean energy deployment. The hybrid solar and storage configuration will support grid stability while helping integrate higher levels of renewable energy. Battery storage will allow excess solar generation to be stored during the day and dispatched during peak demand periods. ([Renew Economy][1])
The approved project includes approximately two million solar panels, associated mounting infrastructure, substations, and grid connection facilities. The integrated battery system will enable the plant to shift generation into evening hours, improving supply reliability and reducing curtailment risks commonly associated with large solar installations.

The Dinawan Solar Farm forms part of the broader Dinawan Energy Hub, a multi-gigawatt renewable development that also includes wind generation and additional storage components. The combined hub is designed to deliver large volumes of clean electricity into the National Electricity Market while replacing aging fossil-fuel generation capacity. ([sparkrenewables.com][3])
The project had been referred to the Independent Planning Commission after receiving more than 50 public submissions, which triggered an additional review under New South Wales planning rules. Following reassessment, the regulator granted approval, allowing the project to move forward toward construction and investment decisions. ([Renew Economy][1])
Once operational, the solar and storage facility is expected to enhance renewable energy penetration while supporting system flexibility. Large battery capacity allows operators to smooth output fluctuations and provide ancillary grid services such as frequency support and peak-shaving capabilities.
The development also contributes to Australia’s broader energy transition strategy, particularly within designated renewable energy zones. These zones aim to accelerate grid-connected renewable projects supported by transmission upgrades and coordinated infrastructure planning.
The Dinawan Solar Farm is expected to generate significant economic benefits, including construction employment, local procurement, and long-term operational roles. Large hybrid projects of this scale also help reduce emissions by replacing fossil fuel-based power generation with clean, dispatchable renewable energy.
With approval secured, Spark Renewables moves closer to delivering one of the largest solar-plus-storage projects in New South Wales. The milestone reflects growing momentum for hybrid renewable developments combining solar generation with grid-scale battery storage to deliver reliable, large-scale clean power.
