Carbon Power Plant Explained
Carbon Power Plant, also known as Castle Gate Power Plant, was a relatively small, 190-MWe coal-fired power station in Utah, US, operated by PacifiCorp. Utah Power & Light constructed its Carbon Steam Generating Plant at Castle Gate in the mid 1950s.[1] Its units 1 and 2, rated at 75 and 113.6 MWe, were placed in service in 1954 and 1957.[2] The plant was located at 39.7272°N -110.8642°W, about 3abbr=onNaNabbr=on north of Helper, Utah, on the east bank of Price River.
The plant, at the time the oldest operational in Utah, was shut down on April 16, 2015, due to new restrictions on emissions of mercury compounds[3] and was demolished in 2016.[4]
