Warradarge hybrid energy project plans would add 500MW of solar generation and 500MW of battery storage. The proposal would sit within the expanded Warradarge Wind Farm in Western Australia. The Shire of Coorow values the development at about A$2 billion/roughly $1.4 billion.
The proposal would create a combined wind, solar and battery renewable energy complex. It would also reuse infrastructure serving the existing wind facility. Consequently, the project could limit additional disturbance and reduce infrastructure duplication.
Warradarge hybrid energy project construction plans
The proposed solar farm and BESS would occupy the existing wind farm development envelope. The site would extend about five kilometers east-west and six kilometers north-south. The development would use existing roads, underground cabling and electrical connections where practical.
The solar facility would generate electricity during daylight hours, while batteries could shift supply later. Therefore, storage would help manage solar variability and changing demand across the network.
The planning proposal allows either a centralized battery or dispersed battery arrangement. However, developers have not selected the final configuration. They also have not determined the battery’s storage duration.
Western Australia’s renewable energy pipeline is also gaining momentum through the Baru Marnda Renewable Energy Project in the Pilbara. The proposed 1.5GW development combines wind, solar and battery storage infrastructure, strengthening the state’s push toward large-scale renewable power generation. Read the latest update on the Baru Marnda project and its progress toward final planning approval.
Warradarge hybrid energy project strengthens grid capacity
The facility would connect near existing 330kV transmission infrastructure serving the South West Interconnected System. Furthermore, the planned Clean Energy Link North should strengthen transmission capacity around the region.
The Mid West already hosts several wind and solar facilities. It also supports new renewable construction, including the Parron Maam Marang and Waddi wind projects.
Meanwhile, hybrid renewable developments are becoming more important as solar oversupply pressures daytime electricity prices. Batteries can store surplus generation and release electricity during stronger demand periods.
Fully integrated wind, solar and battery projects remain uncommon on Australia’s main grid. Kennedy in far-north Queensland is the country’s only operating true hybrid example. Other developers are considering similar combinations at Bungaban, Dinawan and Goyder.
The Warradarge proposal would therefore extend a relatively limited renewable project model. Its scale could also make the site a significant hybrid construction project in Western Australia.
SynergyRED has submitted a development application to the Shire of Coorow. It has also referred the proposal to the Western Australian Environmental Protection Authority.
Public submissions to the Shire close at 4pm on November 2, 2026. The project remains under feasibility and planning review, with final technical decisions outstanding.
