Intermountain Power Plant is a large coal-fired power plant at Delta, Utah, USA. It has an installed capacity of 1,900 MW, is owned by the Intermountain Power Agency, and is operated by the Los Angeles Department of Water and Power.[1][2][3]
The power plant consists of two units each with a generation capacity of 950 MW.[3] Generating units are equipped with General Electric tandem compound steam turbines and Babcock & Wilcox subcritical boilers.[2] The boiler houses of Intermountain Power Plant are 91.75 metres (301.0 ft) and the flue gas stack is 213.67 metres (701.0 ft) tall. The HVDC Intermountain transmission line runs between Intermountain Power Plant and Adelanto Converter Station in Adelanto, California.[2]
Construction on the plant began in September 1981. Commercial operation of unit 1 started in June 1986, and unit 2 in May 1987. The project cost US$4.5 billion.[4][5] When built, it was the largest coal-fired power project in the United States.[4] In 2004, units 1 and 2 were uprated.[6] These works were conducted by GE and Alstom.[2] The plant was originally designed for four units; however, only two units were built.[6] The Intermountain Power Agency planned to build the third unit of 900 MW capacity. This unit was expected to go online in 2012; however, the project was cancelled after its major purchaser, the city of Los Angeles, decided to become "coal free" by 2020.[7][8]
On December 28, 2011, one of the generators failed causing the shut-down of one unit for several months.[9]
Conversion to natural gas
The plant is scheduled to be converted to natural gas by 2025 at a cost of $500 million.[10]
Energy Hub
Energy Capital Group, LLC (ECG) is developing ECG Utah Solar 1, LLC www.ecgutahsolar1.com an 300 MW-AC PV solar plant strategically sited to utilize existing interstate transmission infrastructure on 1754 acres leased from the Utah School and Institutional Trust Lands (SITLA) less than one mile from the Intermountain Power Project (IPP) north of Delta, Utah.
The project’s planned interconnection point is the IPP switchyard which is a point of delivery for the Los Angeles, Anaheim, Riverside, Pasadena, Glendale and Burbank utilities. The switchyard connects to the Southern Transmission System (STS) the 500 HVDC line (Path 27) that travels 488 miles directly to Adelanto Converter Station switchyard in Adelanto, Ca (see map http://www.oatioasis.com/LDWP/LDWPdocs/pathmap6.pdf ). LADWP is a California Balancing Authority and operates the switchyard which makes this project as though it is on California soil for the state Renewable Portfolio Standard (RPS).
