Solar Developer Cancels Washington State Project on Sacred Indigenous Land

A renewable energy developer has pulled its controversial permit application to build an industrial-scale solar facility on an Eastern Washington mountain sacred to Indigenous nations.

Avangrid, a powerful player in the Northwest’s push for green energy development, sought for at least five years to build a solar plant on Badger Mountain. The project site straddled private as well as public lands. The Confederated Tribes of the Colville Reservation and the Confederated Tribes and Bands of the Yakama Nation have protected rights to practice cultural traditions, such as food gathering and ceremonies, on Badger Mountain and other ancestral public lands.

A 2024 investigation by High Country News and ProPublica found that Avangrid and a consultant it retained, Tetra Tech, had omitted key archaeological and cultural information from a state-mandated review of the site, which would have been used for a solar farm. Avangrid continued pushing the project despite a state archaeologist’s warning that the planned development would threaten significant historic sites and current ceremonial activity. An elected member of the Colville Tribal Business Council told the newsrooms at the time that the project would destroy roughly half the root vegetable harvest in the area.
