VFDs for Large Fans and Pumps - City of Ames

The Power Plant operates many large fans and pumps in order to accomplish the electricity production. These fans and pumps include a Force Draft fan and Induced Draft fan, two Boiler Feed pumps, Cooling Tower circulating water pumps, and Cooling Tower fans. Each of these are driven by very large horse-power electric motors. Installing a Variable Frequency Drive (VFD) on each motor would allow for precision control and would provide much greater efficiency, therefor lowering electricity demand. The project is included in the city's 2021/2022-2025/2026 Capital Improvement Program (CIP). As of October 25, 2021, further details regarding design and construction have not been identified.* *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available. As of May 11, 2023, no new information available
