Ya’a’teeh & Welcome to NTUA Online
The Navajo Tribal Utility Authority (NTUA) was established on January 22, 1959, to address the absence of utilities on the 27,000 square-mile Navajo Nation. Since then, NTUA has grown into a self-sustaining, not-for-profit, successful tribally-owned enterprise. NTUA is organized for the operation, maintenance and expansion of electric, communications, natural gas, water, wastewater and generation, including photovoltaic (solar) services for the Navajo people at a low and reasonable cost. In addition to providing multi-utility services, other objectives of NTUA are to promote employment opportunities on the Navajo Nation, and to improve the health and welfare of the residents of the Navajo Nation while raising the standard of life.
