Our Operations

Navajo Transitional Energy Company is the third largest coal producer in the United States that owns Navajo Mine on the Navajo Nation and three mines in the Powder River Basin. Together, these surface coal mines have shipped more than 2.8 billion tons of coal to date and won more than 70 awards for safety and reclamation.

The Navajo Nation is ideally positioned in the Southwest and the home to the Four Corners Power Plant (FCPP) and the busy Four Corners energy hub. In July 2018, NTEC acquired seven-percent ownership in units four and five of the FCPP. As a result of the transaction, NTEC became an owner of a coal-fired power plant, a first for a Navajo Nation enterprise. In September 2024, NTEC was awarded $6.5 million for a Front-End Engineering (FEED) Study to evaluate adding carbon capture to FCPP. It is the first grant of its kind of a tribally owned power plant on tribal lands.

The Navajo Nation boasts some of the cleanest helium deposits on Earth. To harness the potential of these deposits for the benefit of the Navajo Nation, NTEC acquired Tacitus LLC, which included the Tocito Dome, in 2021 and founded NTEC Helium. Since then, NTEC Helium has generated more than $3 million for the Navajo Nation.

Lithium is an essential mineral to global clean energy initiatives and is used in many every-day items such as cell phones and laptops. NTEC is evaluating multiple lithium projects, including the Big Sandy Lithium Project owned by Arizona Lithium (AZL), which could be a significant domestic producer of lithium, benefiting communities throughout Arizona and the U.S.
