Yindjibarndi Energy Corporation (YEC) has marked a historic milestone in Australia’s renewable energy sector by reaching financial close on the Jinbi Solar Project and signing a landmark 30-year Power Purchase Agreement (PPA) with global mining giant Rio Tinto. The deal, announced in May 2026, will see YEC supply 100% of the electricity generated by Jinbi directly to Rio Tinto, underpinning the miner’s commitment to decarbonize its operations in Western Australia’s Pilbara region. This agreement not only secures a long-term energy supply for Rio Tinto but also represents one of the largest Indigenous-led renewable energy initiatives in the country, with the project set to begin construction immediately.
The Jinbi Solar Project, located on Yindjibarndi country in the Pilbara, is YEC’s first solar development and comprises an initial 75 megawatt alternating current (MWac) solar photovoltaic (PV) array, with potential to expand to 150 MWac. The project also includes an option to integrate a Battery Energy Storage System (BESS), enhancing reliability and grid stability. The financial close follows years of collaboration between YEC—a partnership between the Yindjibarndi Aboriginal Corporation (YAC) and renewable energy developer ACEN Corporation—and Rio Tinto, which began with a memorandum of understanding in October 2023.
YEC’s formation in 2023 was a pivotal moment for the Yindjibarndi people, who hold native title over approximately 13,000 square kilometers of land in the Pilbara. The corporation was established to develop, own, and operate large-scale renewable energy projects, with an ambitious target of up to 3 gigawatts (GW) of capacity across wind, solar, and energy storage. The Jinbi project is the first of several planned developments, reflecting a broader strategy to leverage the region’s abundant solar resources while ensuring economic and cultural benefits flow back to the Traditional Owners.
Rio Tinto’s decision to partner with YEC is part of its broader strategy to transition to low-carbon energy sources. The miner has previously committed to reducing its greenhouse gas emissions by 50% by 2030 and achieving net-zero operational emissions by 2050. The Jinbi PPA aligns with these goals, providing a stable and sustainable energy supply for Rio Tinto’s operations in the Pilbara, including its Kwinana and Burrup Hub sites.
The Stakeholders and What’s at Stake
The Jinbi Solar Project involves a complex web of stakeholders, each with distinct interests and roles. At the center is the Yindjibarndi Aboriginal Corporation, which holds native title over the land where the project is situated. The corporation’s involvement ensures that the development aligns with the community’s cultural values and economic aspirations. ACEN Corporation, a leading renewable energy developer, brings technical expertise and project management experience, while Rio Tinto provides the long-term energy demand and financial backing necessary to bring the project to fruition.
For the Yindjibarndi people, the project represents more than just a renewable energy initiative—This proves a pathway to economic self-determination and cultural preservation. The partnership with Rio Tinto and ACEN offers opportunities for local employment, training, and community benefits, including revenue sharing and support for Indigenous-led businesses. The project also underscores the potential for Indigenous communities to lead Australia’s transition to a cleaner energy future.
Rio Tinto stands to benefit from a reliable, low-cost, and low-emission energy source, supporting its sustainability targets and operational resilience. The 30-year PPA guarantees Rio Tinto access to renewable energy, reducing its exposure to volatile wholesale electricity prices and carbon costs. Meanwhile, the broader energy market in Western Australia is set to benefit from increased renewable capacity, contributing to the state’s goal of achieving net-zero emissions by 2050.
From MOU to Construction: A Timeline
| Date | Milestone | Description |
|---|---|---|
| October 2023 | MOU Signed | Rio Tinto and Yindjibarndi Energy Corporation sign a memorandum of understanding to explore renewable energy opportunities in the Pilbara. |
| December 2024 | Development Approval | Yindjibarndi Energy Corporation receives development approval for the Jinbi Solar Project from the City of Karratha. |
| May 2026 | Financial Close | Yindjibarndi Energy Corporation reaches financial close on the Jinbi Solar Project and signs a 30-year Power Purchase Agreement with Rio Tinto. |
| May 2026 | Construction Begins | Construction of the 75 MWac solar project commences, with potential expansion to 150 MWac and integration of battery storage. |
The next major checkpoint for the Jinbi Solar Project is the commencement of construction, which has already begun. According to YEC, the project is on track to deliver its first electricity to Rio Tinto within the next 12–18 months, pending final regulatory approvals and weather conditions. The corporation has also indicated that it will continue to engage with local communities and regulators to ensure the project’s smooth progression and to explore opportunities for further expansion.
Why This Deal Matters for Australia’s Energy Future
The Jinbi Solar Project is more than a commercial agreement—it is a model for how Indigenous communities, renewable energy developers, and major corporations can collaborate to deliver sustainable outcomes. By securing a long-term PPA with Rio Tinto, YEC has demonstrated the viability of Indigenous-led renewable energy projects, paving the way for similar initiatives across Australia. The project also highlights the importance of regional renewable energy development in supporting Australia’s national emissions reduction targets and energy security goals.
For the Pilbara region, the project is a catalyst for economic diversification, reducing reliance on traditional mining activities and fostering a cleaner, more sustainable future. The integration of battery storage further enhances the project’s value, providing grid stability and backup power for critical infrastructure. As Australia continues to transition away from fossil fuels, projects like Jinbi will play a crucial role in shaping a resilient and inclusive energy sector.
