YEC is a partnership between the Yindjibarndi Aboriginal Corporation and the Philippines-based ACEN Corporation, with Yindjibarndi holding between 25% and 50% of project-level equity in the company’s renewable energy developments and retaining primary land tenure across project areas.

Baru Marnda is proposed to include up to 1,000MW of wind generation and up to 500MW of solar generation, alongside a battery energy storage system (BESS).

The Development Application draws together assessment work spanning planning, environment, cultural heritage, water, transport, bushfire, noise, visual impact, aviation and land tenure.

At a national scale, the proposed wind component places Baru Marnda within the emerging class of gigawatt-scale Australian wind projects, and within Western Australia, its proposed capacity would make it one of the state’s largest onshore wind developments.

The project would connect renewable energy generated on site to the North West Interconnected System (NWIS), the isolated grid serving the Pilbara’s mining and industrial operations, and was first referred for assessment under the federal Environment Protection and Biodiversity Conservation (EPBC) Act in July 2025, when YEC proposed up to six potential solar array sites northwest and southeast of the Rio Tinto rail corridor, with four to be included in the final design.

Construction was expected to begin in 2028 and be carried out in stages over three to six years, subject to the necessary approvals.

Baru Marnda also aligns with the Western Australian government’s Pilbara Energy Transition Plan.

YEC has been awarded Priority Project status for the Chichester Range Corridor, one of four priority common-use transmission corridors identified for the Pilbara, which would connect the Maitland Strategic Industrial Area with renewable energy generation to its south, potentially including Baru Marnda.
