The Alliance for Tribal Energy (the Alliance) is an Indigenous-led 501(c)(3) nonprofit organization with a mission to support the self-determined efforts of Native American tribes to transition toward clean energy systems. Through the Alliance’s Preferred Provider Program, clean energy service or development providers can apply to become Preferred Provider Members of the Alliance, and, after a rigorous evaluation process, become eligible for introductions to our member tribes.
