On September 20, 2019, the Navajo Tribal Utility Authority (NTUA) celebrated the grand opening of its newly expanded thermal power generating facility in Kayenta, Arizona. The project, known as Kayenta II, is the first and only utility-scale solar power generation facility to be 100% owned and operated by a tribal nation in the United States. The Kayenta project, which includes an earlier phase of 27.5 installed megawatts completed in late 2017, now totals approximately 55 megawatts of installed solar capacity. The project will serve approximately 36,000 residents and businesses within the Navajo Nation. NTUA also partnered with Salt River Project in a power purchase agreement for the offtake of the excess energy generated, as well as, the renewable energy credits produced from the Kayenta facility.
