La finalización de la conexión de la planta de Ottumwa marca el tercer proyecto EPC exitoso para Alliant Energy

On Monday, Nov. 16, Alberici crews at the Ottumwa Bottom Ash project completed a critical tie-in outage at Alliant Energy’s 726-megawatt Ottumwa Generating Station. Working seven days a week for nine weeks, the Alberici team demolished, reinstalled, and commissioned the plant’s entire under-boiler system to accommodate installation of new bottom ash conversion and pyrite separation equipment and conveyors. To ensure on-time completion, Alberici self-performed more than half the project’s entire scope of work.

This challenging Engineer-Procure-Construct (EPC) retrofit project will help improve environmental conditions by diverting combustion products from nearby ash ponds. It is Alberici’s third successful EPC contract for Alliant Energy and its second consecutive project at the utility company’s power plant in Ottumwa, Iowa. Alberici completed installation of a selective catalytic reduction system (SCR) at the plant in 2019. In more than four years on site, Alberici has performed nearly 800,000 hours without a single recordable injury.
