Iatan Power Plant

After working with the Sierra Club to pursue initiatives to offset carbon dioxide emissions with a complete air quality control system upgrade to Unit 1, KCP&L Iatan Unit 2 is now one of the country’s cleanest and most efficient coal-fired power plants. Due to modernization and retro- fitting to capture emissions, combined emissions from both plants are be lower than current emissions from Iatan Unit 1 alone. 

The Kiewit team was awarded the contract to construct a portion of the new 900-megawatt coal-fired power plant and a portion of upgrades to the existing Unit 1. Unit 1 upgrades consist of a wet flue gas desulfurization system for sulfur dioxide (SO ) control, a pulse jet fabric filter baghouse for particulate matter control and a selective catalytic reduction system for nitrogen oxides (NO ). Unit 2 includes a Toshiba steam turbine, a cooling tower, col- lector wells that provide the necessary water supply for the facility, and a zero-liquid discharge system designed to treat scrubber blowdown. 

Kiewit’s past construction experience allowed the project team to work side by side with other contractors to construct Unit 2 and upgrade Unit 1. Kiewit’s balance-of-plant scope included pouring concrete foundations for numerous buildings on both units, turbine building structural steel, piping and mechanical installations, as well as the complete electrical package for both units.
