Renewable Energy Generation
The Navajo Tribal Utility Authority (NTUA) has a primary mission to provide basic utility services
(electricity, water, gas, wastewater) on the Navajo Nation, as found in the NTUA Plan of Operation. This
Plan also authorizes the NTUA to develop energy generation projects in support of this mission.
The Navajo Nation is blessed with abundant natural resources, including coal, oil and natural gas, as well
as renewable resources, such as wind and solar. While the Navajo Nation has historically focused on oil
and gas operations and the sale of coal, these have resulted in limited financial income and with virtually
no power generated for consumption by the Navajo people. The NTUA is taking on a leadership role in
the development of Renewable Energy resources and embraces a vision for an Energy Economy that
ensures long-term economic and social progress on the Navajo Nation and positively impact the regional
economies of the Four Corners states.
The NTUA has identified three sites owned by the Navajo Nation for utility-scale wind generation
1. Boquillas Ranch (Seligman, AZ): Potential for up to 500MW wind farm; lease for Phase 1 was approved
by the Navajo Nation Council on December 22, 2009, with groundbreaking anticipated in December, 2010.
2. Gray Mountain (Cameron, AZ): Potential for up to 500 MW wind farm; likely the best wind site on the
Navajo Nation; NTUA is working with the local community and potential developers to realize this project.
3. Black Mesa (Kayenta, AZ): Potential for up to 200 MW wind farm; preliminary wind data warrants formal
wind study at two sites on Black Mesa.
Additionally, the NTUA is actively exploring other potential wind sites throughout the Navajo Nation
The latitude and altitude of the Navajo Nation also make it extremely attractive for solar generation
development. To accelerate solar deployment, the NTUA is partnering with the U.S. Environmental
Protection Agency to assess and prioritize potential sites for Solar development.
In addition to wind and solar, the NTUA is exploring additional technologies, including Waste-to-Energy,
Geothermal and Biomass opportunities available on the Navajo Nation.
