Walter Scott, Jr. Power Plant, Iowa

Walter Scott, Jr. Power Plant (also known as the Walter Scott, Jr. Energy Center), is located near Council Bluffs, Iowa, adjacent to the Missouri River, the source of its cooling water. In its original configuration the plant was home to three coal-fired units, whose combined output capacity was 821MW. Unit 1's output capacity was 43MW, becoming operational in 1954; Unit 2's output capacity was 88MW, becoming operational in 1958; while Unit 3's output capacity was 690MW, becoming operational in 1979. (The plant was then known as the Council Bluffs Power Plant.) Construction on what was to become 790-MW Unit 4 began in 2003, with the unit becoming operational in 2007. In 2015, Units 1 and 2 were retired in order to comply with pollution control standards, leaving only Units 3 and 4 operational, resulting in a combined output capacity of 1,480MW. Currently the plant is the largest power generating facility in the state. The Powder River Basin is the source of the plant's coal. The plant is owned and operated by MidAmerican Energy, a subsidiary of Berkshire Hathaway Energy.
