The Navajo Generating Station coal-fired power plant near Page burned the last of its coal Monday, marking the end of the plant's 45-year run, Salt River Project announced.
The plant was the largest coal plant in the West, and its closure will affect the entire region.
The last bit of usable coal burned Monday and the power plant, which could produce 2,250 megawatts of power at full capacity, sent its last electrons down the transmission lines to Phoenix, Tucson and Las Vegas at about 12:09 p.m.
