| George Clayton McMillan posted, cropped Navajo Generating Station in Page, AZ. 2250MW coal fired facility. Worked here for a year during the Decommissioning of the unit. Andrew Shafer: Pretty sad it’s wiped off the face of the earth now. Dan McKenna: Any idea who manufactured the boilers? I thought they were either Babcock&Wilcox or Combustion units. Any idea? David Matesky: They are CE Supercritical boilers. Scott Patulski: David Matesky you are correct sir. Seltzer design to be specific with split furnaces firing tangentially from 8 corners. Charles Friedman: When I began working at Combustion Engineering almost 50 years ago, I worked in Field Testing, and Performance Results. I never got to the Four Corners power plant, but others in my department were there, in order to conduct boiler performance and emissions tests on the Unit 1 boiler. In later years, the company, and the successive companies, built even larger steam generators, up to 660,000 Lb/hr SH steam flow, supercritical, lignite fired, with 990 MW generator net output. Joseph Hallstrom: Charles Friedman, not trying to be picky but 990MW from 660,000 lb/hr of SSH steam? Maybe you missed a zero. Allen England: Didn't they replace the plant with 250 mw of solar panels? |

| Mining #Shorts posted The Navajo Generating Station was one of the most recognizable coal plants ever built in the American West. Located near Page, Arizona, the facility operated for more than four decades and became deeply tied to the economy of the Navajo Nation and the wider Southwest power grid. Construction started in the early 1970s and the plant eventually reached 2,250 megawatts across three generating units. At full operation, it supplied electricity to Arizona, Nevada and California while also powering the pumps of the Central Arizona Project, the massive water system carrying Colorado River water across the Arizona desert. The station burned coal from the nearby Kayenta Mine, with trains delivering fuel continuously across northern Arizona. For many Navajo and Hopi families, the mine and plant created some of the region’s highest-paying industrial jobs. Tax revenue and lease payments became critical sources of income for local communities. But the plant also carried enormous controversy. Environmental groups targeted it for decades because of emissions affecting air quality around the Grand Canyon and the broader Southwest. By the 2010s, cheap natural gas and rapidly expanding solar generation made coal power increasingly difficult to justify economically. In 2017, utility owners voted to shut the station down years earlier than originally expected. The final coal was burned on November 18, 2019, ending operations after roughly 45 years. One year later, the plant’s famous smokestacks were demolished, marking the end of one of America’s most important coal-fired power stations. - Photo: Myrabella / WikiCommons Richard Travis: That plant had good sulfur dioxide scrubbers later on in its life. Photo could be early or a time with a low dew point. Troy Mitchell: They have to wait for the coldest day of the year to take the photos. |

| Troy Mitchell commented on the above post I Took this photo myself in Utah on a 96° day when everybody in Utah’s air conditioning was running full blast. To me It looks like the picture above is Both AI and or taken on a cold day when the warm air turns into steam. Isn’t it funny how we let people that don’t know their head from a hole in the ground run this country. |

| vox, Adrian Herder/Tó Nizhóní Ání, courtesy of Wahleah Johns/National Renewables "The three 775-foot smokestacks of the 2,250-megawatt Navajo Generating Station (NGS) — the West’s largest coal plant — were demolished December 18, [2020]." |
Even more jobs were lost at the nearby mine that supplies the lignite coal.

| coconino "The mine to mouth’s backbone is the 80 mile long electric railroad supplying Kayenta’s only customer – the Navajo Generating Station (NGS). NGS consumes 240 rail cars of the Kayenta Mine’s coal every day." |
