Spark Renewables secures federal approval for Dinawan solar and battery project in NSW, Australia

Type: Development · Technology: Hybrid · Country: Australia · Capacity: 800 MW · Value: $940M · Announced: 2026-07-07

Spark Renewables, a Sydney-based renewable energy developer owned by Malaysia’s Tenaga Nasional Bhd (TNB), secured federal approval under Australia’s Environment Protection and Biodiversity Conservation (EPBC) Act for its $1.35 billion (USD 940 million) Dinawan solar and battery project in southwest New South Wales. The hybrid facility combines an 800 MW solar installation with up to 300 MW of battery energy storage (expandable to four hours) and a separate 707 MW wind component, spanning 2,600 hectares near Jerilderie within NSW’s South West Renewable Energy Zone (REZ). The project, targeting a final investment decision in 2027 and construction start later that year, will generate enough clean energy to power 142,000 homes annually while enhancing grid stability and reducing reliance on fossil fuels. Spark has been allocated 1 GW of access rights in the South West REZ, including 300 MW of solar and 1,200 MW of battery storage, with the initial 300 MW solar phase to be built first as grid capacity allows. The federal approval includes strict environmental compliance conditions, annual reporting requirements, and rapid non-compliance notifications, following prior endorsement by the NSW Independent Planning Commission in April 2026. The project is also supported by the Australian government’s Capacity Investment Scheme (CIS) underwriting deal, accelerating its path to commercial operation.
