Australian developer Spark Renewables announced that the first phase of its Dinawan Energy Hub, the Dinawan Wind Farm (Stage 1), has been selected under the fourth round of the Capacity Investment Scheme (CIS). The 357 megawatt (MW) project is located between Jerilderie and Coleambally in the state of New South Wales. This outcome paves the way for secured funding of one of the country’s most ambitious renewable energy generation projects.
A multi-technology energy hub
The Dinawan Energy Hub will deliver a total capacity of 1.3 gigawatts (GW) in multiple phases. In addition to the initial wind farm, the second phase will include a further 350 MW wind project, while the third will integrate a 300 MW solar plant combined with a 300 MW/1,200 MWh battery energy storage system. Overall, the complex will supply around 1 GW of new capacity to the National Electricity Market and provide 300 MW of four-hour battery storage.
The site is strategically located near the Dinawan Substation within the South West Renewable Energy Zone, enabling efficient grid integration. Spark Renewables secured access rights to this energy zone in April 2025.
Government support and strategic evaluation
The Capacity Investment Scheme, led by the Department of Climate Change and Energy, is a public revenue-underwriting mechanism aimed at accelerating investment in renewable energy projects. Submissions are assessed on criteria including electricity cost competitiveness, regional economic impact, local content procurement, and engagement with Indigenous communities.
The Dinawan Energy Hub’s development is supported by ecological and technical studies. A response to submissions on the Environmental Impact Statement was submitted to state authorities in August 2025, marking a step forward in the approvals process for full-scale delivery.
Targeting financial close for phase one
Anthony Marriner, Chief Executive Officer of Spark Renewables, stated that the project is “the only initiative in the country to combine wind, solar, and battery storage on a single site.” He also emphasised the importance of CIS support in advancing the project toward financial close, a key milestone before construction can begin.
Dinawan’s selection under the federal programme strengthens investment momentum in Australia’s renewable energy zones. The technological mix deployed at Dinawan is designed to meet network stability requirements and attract long-term capital.
