Mohave Power Station (known also as Mohave Generating Station, or MOGS) was a 1580 megawatt electric (MWe) coal-fired power plant that was located in Laughlin, Nevada. Southern California Edison is the majority owner of the plant and was its operator. The plant entered commercial operation in 1971. A steam line that ran near the plant's control room and cafeteria ruptured on June 9, 1985, fatally scalding six and injuring ten more. In 2005, the plant was shut down and was later dismantled. Design The plant was composed of two units capable of generating 790 MWe each. During normal operation, output varied between 350 and 750 MWe; the baseload plant operated with a capacity factor of 71.5% between 1990 and 1998. Combustion Engineering supplied the boilers and GE supplied the turbine-generators. Bechtel was the architect-engineer, responsible for engineering, procurement and construction. The Mohave Generating Station was built on a site in the Mojave Desert adjacent to the Colorado River in Laughlin, Clark County, Nevada. It had supercritical boilers and cross-compound steam turbines. The plant was owned by a utility consortium of operator Southern California Edison Co (56%), LADWP (10%), Nevada Power (14%), and Salt River Project (20%). Mohave was the only power plant in the United States that used coal delivered by coal-slurry pipeline, composed of approximately half coal and half water. The 18 inch (460 mm) diameter Black Mesa Pipeline ran to the plant from the Peabody Energy Black Mesa Mine in Kayenta, AZ, and could deliver per hour. The coal slurry was stored in four storage tanks or eight Marcona ponds. Each storage tank held up to , the equivalent of of dry coal; the conical Marcona ponds were each in diameter and deep, for a capacity of or of coal. Eight full ponds was the equivalent of a 40-day supply of coal for the plant. The slurry transport water was separated from the coal through a series of centrifuges, which removed approximately 75% of the water, the damp coal then passed through pulverizers for drying and grinding. The plant had a total of 20 pulverizers, each of which could process of coal per hour. The separated water was stored in clariflocculators to allow remaining coal fines to settle; the water was then recycled for cooling tower water makeup; this and all other waste water was reused, making Mohave a zero-discharge facility. At full capacity, the plant consumed of
