The Ramona Band of Cahuilla was one of the first Tribes to develop its entire reservation off-grid using renewable energy as the primary power source. The Tribe purchased and installed the primary components for a 65-80 killowatt-hours per day center wind/PV/propane generator hybrid system that provides power to the reservation’s housing and office buildings. Ninety percent of the electrical and thermal energy needed to power Tribal housing and office buildings come from wind or solar energy. Propane is used as a back-up energy source.
