Mining Giant Signs 30-Year Off-Take Deal to Underpin Indigenous-Led Pilbara Solar and Battery Project

Why It Matters

The agreement demonstrates that Indigenous‑controlled projects can meet rigorous commercial standards while accelerating the mining sector’s transition to clean energy, a critical step for both climate goals and community empowerment.

Key Takeaways

• YEC secured a 30‑year PPA delivering 100% power to Rio Tinto.
• First stage launches 75 MW solar, expandable to 150 MW with storage.
• Project marks a major Indigenous‑led renewable venture in the Pilbara.
• Rio Tinto aims for 90% renewable energy by 2030, boosting decarbonization.

Pulse Analysis

The Jinbi Solar Project illustrates a growing trend where Indigenous groups are taking the helm of large‑scale renewable developments. Formed in 2023 by the Yindjibarndi Aboriginal Corporation and Acen Corp, YEC leverages exclusive native title rights to develop up to 750 MW of wind, solar and battery capacity on Yindjibarndi country. By locking in a 30‑year PPA with Rio Tinto, the venture secured the financing needed to move from concept to construction, signaling to investors that culturally rooted projects can deliver the predictability required for utility‑scale energy assets.

For Rio Tinto, the partnership is a strategic lever in its broader decarbonisation roadmap. The miner currently sources roughly 78% of its power from renewables, largely thanks to hydro in Canada, and targets 90% by 2030. The Jinbi agreement adds a domestic, zero‑emission supply line for its Pilbara iron‑ore operations, reducing reliance on diesel generators and aligning with the industry’s shift toward greener mining practices. While Fortescue has already pledged a “real zero” target, Rio’s commitment to underwrite about $7.5 billion AUD (≈ $4.95 billion USD) of new wind, solar and storage projects in Queensland underscores its competitive response.

Financially, the deal dovetails with Australian government incentives that earmark $1 billion AUD (≈ $660 million USD) each for renewable support in the Gladstone and Pilbara regions. The off‑take contract enables YEC to issue a notice to proceed, mobilising civil works through Yurra and construction services from DT Infrastructure. Beyond the immediate power supply, the project creates long‑term economic opportunities for the Yindjibarndi people, offering jobs, revenue streams, and a model for future Indigenous‑led energy ventures across the country.
