Intermountain Generating Station, Utah

The Intermountain Generating Station is the central component of Intermountain Power Project, a $4.5 billion project to supply electricity to Southern California and other markets. The plant was built in this remote part of west-central Utah, in the Sevier Desert, and is connected directly to the edge of Los Angeles by a 490 mile long high voltage DC line. The massive coal-fired power plant, built in the mid 1980's, produces over 1,600 megawatts of power, and is supplied by coal mines in central and eastern Utah.  In 2013, the Los Angeles City Council approved a plan to convert the facility from coal to natural gas by 2025, at an estimated cost of $500 million.
