Navajo Power Station, Page, Arizona

Navajo Power Station, Page, Arizona

Navajo Generating Station is a coal-fired powerplant with a power of 2280 megawatts located on the Navajo Indian Reservation, near Page, Arizona, USA. Navajo Generating Station has three 236 meter high chimneys, which are among the tallest structures in Arizona. This plant provides electrical power to customers in Arizona, Nevada, and California. It was assembled during the 1970s and began producing commercial power in 1975. The construction costs were about $650 million, with an additional $420 million for new environmental scrubbers, constructed during the 1990's.

The power plant is served by coal mined at the Kayenta Mine near Kayenta, Arizona, and hauled by the Black Mesa and Lake Powell railroad. The Kayenta mine ships about 8 million tons of coal each year to the power plant.

The power plant is equipped with electrostatic precipitators to control fly ash, and has a lined water reservoir to help recover and contain process waste. The power plant features scrubbers for each tower to control SO2 pollution. The project began in 1994 and was completed in 1999.

In 2008, installation began on Low-NOx burners to reduce emissions of smog-forming nitrogen oxide, also known as NOx. The job was finished in 2011 at a cost of approximately $45 million. The U.S. EPA is in the process of setting rules to control NOx emissions at coal-burning power plants like Navajo to protect visibility in the region. The EPA is looking at the Low-NOx burners. They are also considering a very different NOx control system known as Selective Catalytic Reduction (SCR).

Images of the plant are featured in the Godfrey Reggio film Koyaanisqatsi.
