About the plant
Location: LeChee Chapter of the Navajo Nation near Page, Arizona.
|U.S. Bureau of Reclamation||24.3%|
|Arizona Public Service Co.||14.0%|
|Tucson Electric Power||7.5%|
Service area: NGS serves electric customers in Arizona and Nevada. The station also supplies more than 90% of the power needed to pump water through the Central Arizona Project (CAP). CAP is both the single largest end user of power as well as the largest single source of renewable water supplies in Arizona.
Capacity: 2,250 megawatts (MW) from three 750 MW units.
Fuel source: Low sulfur bituminous coal from Peabody Western Coal Company's Kayenta Mine located 78 miles to the southeast. Coal is transported via a dedicated electric train.
Plant construction: Construction began in 1969. The first unit began producing electricity in 1974. Commercial operation of the other units began in 1975 and 1976.
Construction costs: $650 million, including $200 million in environmental-control equipment. An additional $420 million was spent on new sulfur dioxide (SO2) scrubbers in the 1990s, and $45 million was spent from 2009–11 to reduce nitrogen oxide (NOx) emissions.
Employment: NGS employs nearly 500 full-time employees, more than 90% of whom are Navajo.
Air quality and emissions: NGS complies with all federal air quality standards and emission limitations.
Electrostatic precipitators capture 99% of the fly ash, which is recycled for use in concrete, cement and other construction materials. Limestone scrubbers remove over 95% of SO2 emissions. Low NOx burners and separated overfire air technology reduce NOx emissions by approximately 40%. Learn more about our environmental standards and regulations here.
Waste management: A successful NGS waste management program focuses on waste minimization. NGS consistently achieves its goal to be a small generator of hazardous waste and, for significant periods of time, meets the more stringent, conditionally exempt small-quantity generator status.
