Navajo Tribal Utility Authority – an enterprise of the Navajo Nation







Call Before You Dig
















Welcome to Navajo Tribal Utility Authority Online

Ya’aa’teeh. We at the Navajo Tribal Utility Authority continue to address the multi-utility needs of the Navajo Nation.
NTUA supplies and extends electricity, natural gas, water, wastewater treatment, renewable energy and communications (including wholesale transmission of voice, data, graphics and other information) services to homes and businesses throughout the 27,000 square mile Navajo Nation and neighboring communities.


NTUA purchases electrical power from off the Navajo Nation and transmits that power to homes throughout northern Arizona, northwestern New Mexico, and southeastern Utah. Even as NTUA works hard to meet the basic utility needs of the Navajo Nation an estimated 16,000 families are without access to electricity, and many more homes and families are without access to basic infrastructure, such as telephones, water, wastewater, and natural gas services.

As a non-profit enterprise, NTUA receives federal loans and grants to extend electrical power to rural communities. What money NTUA generates is returned to maintain, operate, and upgrade utility infrastructure.

With each project, NTUA seeks to strengthen the partnership with the Navajo Nation, the federal government and other outside governments to create a team commitment to continue provide reliable utility services to residents living throughout the Navajo Nation. NTUA knows the territory and we pledge to continue Building Together for Progress – a mission that has been Progressing Since 1959.
