Major solar storage project demonstrates potential for remote and rural Australia

Boosting mining sustainability with solar and storage

A 10 MW solar plant with 6 MW of battery storage at Sandfire Resources DeGrussa Copper-Gold Mine in Western Australia is demonstrating the significant potential for off-grid renewables in regional and remote Australia.

Our investment

The CEFC committed $15 million in debt finance to the project, which also received $20.9 million in recoupable funding from the Australian Renewable Energy Agency (ARENA). The CEFC finance was fully repaid in March 2021. The project is owned by leading French renewable energy firm Neoen. juwi Renewable Energy was responsible for the project development, EPC and O&M. Perth-based surveying and infrastructure construction company OTOC Limited constructed the plant. 

our impact 

The $40 million project involved 34,080 solar PV panels using single-axis tracking technology, covering over 20 hectares near the mine site.  

When the CEFC made its finance commitment in 2015, the project was Australia’s largest solar and battery storage project to date. The DeGrussa Solar Project was commissioned and achieved full generation capacity in June 2016. The solar facility was designed to provide the majority of Sandfire's daytime electricity requirements, offsetting about 5 million litres of diesel fuel per annum and abating over 12,000 tonnes of CO2-e annually.
