Ngarluma Aboriginal Corporation will develop an 80MW solar farm near Karratha in Western Australia's vast Pilbara region to supply Rio Tinto's operations across the Pilbara with renewable energy.
It is the first solar project between the Ngarluma people and iron ore giant after a recent memorandum of understanding to explore opportunities for renewable energy projects on Country.
Expected to be next to Rio Tinto's existing Yurralyi Maya Power Station near Karratha, the project has potential to displace up to 11 per cent of natural gas currently used across Rio Tinto's integrated mining operations in the Pilbara, reducing its emissions by up to 120kT CO2e per year, once complete.
A feasibility study was expected to be completed in early 2025, with commissioning in 2027, subject to relevant approvals and final investment.
Approximately 600MW to 700MW of renewable energy would be needed by 2030 to displace the majority of gas used across Rio Tinto's Pilbara power network.
Additional renewable energy is also required to power widespread fleet electrification, expected after 2030.
Ngarluma Aboriginal Corporation CEO Ljuba Mojovic said the first renewable energy project with Rio Tinto would reduce emissions and create economic opportunities for the Ngarluma People.
"The solar farm project will enable NAC to realise sustainable revenues, increase contracting opportunities and contribute to a positive environmental impact in the Pilbara," she said.
"This project development is a testament to the enduring strength of our special relationship with Rio Tinto, and our shared commitment to working together to create a more sustainable future."
Rio Tinto managing director of rail, port & core services, Richard Cohen, said the company was proud to progress the project with the Ngarluma people.
"We are grateful for their efforts and support to reach this important milestone," he said on Monday.
"Developments like this are about more than reducing emissions – they're critical for economic opportunities and strengthening our connection with the Ngarluma People.
"It underscores the significance of our long-term relationship with them and demonstrates our commitment to working together to contribute to a more sustainable future."
