Alinta Energy is the latest company to sign a heritage protection agreement with Yued Aboriginal Corporation.
Alinta is the third renewable energy project developer to sign a Yued Heritage Protection Agreement in recent weeks.
In early June, Yued struck a deal with Carbon Positive Australia, and two weeks ago reached agreement with Neoen Australia.
The Aboriginal corporation said on Wednesday that the pressure on the WA's Traditional Owners "to meet the challenges and opportunities such developments present" is intensifying.
With limited resources, Yued Aboriginal Corporation states its mission "is to ensure that Yued people are taking part in and benefiting from the significant investment planned to occur on their lands and waters".
The Yued Heritage Protection Agreement establishes the processes by which consideration is given to activities planned by project proponents. Under a YHPA, proponents submit their planned Activity Notice which is considered by YAC's Cultural Advice Committee.
That Committee (CAC) then provides advice to YAC's management team on how to best ensure that cultural heritage is identified and protected.
Yued Aboriginal Corporation chief executive Rewi Lyall said "the clean energy transition is generational change".
"Unlike such moments in history, it is imperative that this one builds up Aboriginal Western Australians rather than leave them behind. Again," he said.
"This heritage protection agreement with Alinta Energy lays the ground for developing a further agreement that realises the potential of a relationship between Yued and the company."
Alinta Energy Head of Power Development (West Coast) Linden Blair said signing the Yued Heritage Protection Agreement is "a meaningful step forward for Alinta's proposed projects on Yued Boodja".
"It ensures we have an agreed process to identify and protect cultural heritage, and is a first step to strengthen our connection with the Yued community."
