Lower operating and maintenance costs
Greater irrigation system flexibility
Simple, consistent pressure control
Variable frequency drives (VFDs) on irrigation pumps make your life easier. Have better flow control, reduce the wear and tear on your pump motor and bearings, have the flexibility to effortlessly match your irrigation needs, eliminate water hammer in the mainline, and save money on your utility bills.
Plus, Chelan PUD will pay for up to 75% of the cost of your upgrades.
Incentive
Custom Amount
Custom incentive paid to add a variable frequency drive (VFD) to an irrigation pump. Please contact us to spec your upgrade.
Several factors need to be considered before deciding whether to install a VFD on your irrigation pump:
- How is the pressure of the existing pump controlled?
- Does the demand for water vary throughout the day or during the irrigation season?
- How much pressure does the pump have to deliver before any water can begin to flow?
- Is the pump large enough to justify installing a VFD?
- How is the pump operated relative to its rated performance curve?
Incentives are based on kWh savings determined using the Irrigation Pump Resource$mart Application calculations and are capped at 75% of project costs.
Ask Jim White, our senior energy conservation engineer, about incentive calculations for your project.
