Drives for Motors and Pumps (VFDs)

With single-speed motors using more power than necessary, you can save electricity by switching to variable frequency/speed drives (VFD), to match motors speed with actual load requirements. Let us help. We’ll provide a contractor database, expert assessment and cash rebates toward VFD purchases and installation.

To be eligible for a rebate, these energy-saving devices must be newly installed on (retrofitting of existing VFDs are not eligible): 

  • HVAC
  • Cooling tower fans
  • Chilled water pumps
  • Condenser water pumps
  • Hot water pumps
  • Air compressors
  • and other motor upgrades


  • Apply for rebates of $.05/kWh saved annually, offsetting upgrade costs and reducing payback time.
  • Lower operating costs.  New VFDs delivery can help deliver energy savings, paying for themselves quickly.
  • Reduce maintenance costs. Energy-efficient motors can run cooler, last longer and reduce facility heating loads.
  • Reduce motor lifecycle costs.
  • Reduce energy losses through improved design, tighter tolerances, better materials and improved manufacturing techniques. 

Sample Savings—and, you can estimate your rebate.
