Ya’aa’teeh. In 1959, NTUA started out as a small water utility in Shiprock, NM. In decades since, NTUA has grown into the largest multi-utility enterprise owned and operated by an American Indian tribe. NTUA is proud of its history and celebrates its progress. As a not-for-profit enterprise of the Navajo Nation, NTUA provides electric, water, wastewater, natural gas, solar energy, and communications services. We also take deep pride in our work and have the commitment to serve the multi-utility needs of the Navajo Nation.  . In Navajo, the phrase “Niandeiilnish” means “We work for You”. In keeping with that principle, NTUA works for the People with teamwork and respect. That has been our primary mission since 1959.
