Variable Frequency Drives

Find consistent energy savings with VFD technology.

Focus on Energy offers financial incentives for the installation of energy-efficient variable frequency drives (VFDs) in existing buildings. Incorporating energy-efficient VFDs into your facility is a great way to reduce costs and boost your bottom line. By keeping motors from running at 100 percent capacity constantly, or cycling fully on or off, virtually any application that uses motors to drive fans and pumps can find significant savings. The types of environments that often benefit from VFDs include:

  • Industrial Manufacturing
  • Universities
  • Hospitals
  • Office Buildings
  • Facilities
  • Food-Processing Plants


  1. 1

    Determine if your project requires pre-approval. Projects with incentives >$25,000 require approval BEFORE project initiation or equipment purchase. To obtain pre-approval, complete and submit the appropriate equipment incentive application.

  2. 2

    Review the incentive eligibility requirements and, if necessary, refer to the prequalified equipment list. Purchase and install new equipment.

  3. 3

    Submit a completed incentive application and an itemized invoice within 60 days of equipment installation.

  4. 4

    Receive your incentive check in the mail and enjoy saving energy with energy-efficient VFDs.

VFDs for Existing Building - Equipment Qualifications

$50 Per HP up to 50% of project cost

  • Incentives are available for new, installed variable frequency drives that meet the equipment requirements.
  • VFD must be installed on a centrifugal pump or fan. The pump or air handling system must operate a minimum of 2,000 hours annually and may not exceed 500 horsepower.
  • Redundant or back-up units do not qualify. Routine replacement of existing VFDs does not qualify.
  • VFDs added to chillers and air compressors do not qualify for this incentive, but custom incentives may be available.
  • VFDs added to kitchen ventilation hoods do not qualify for this incentive. Use the Kitchen Hood Ventilation Controls offer on the Food Service application.
  • VFD speed must be automatically controlled by differential pressure, flow, temperature or other variable signal.
  • Units installed only to allow soft starts are not eligible. The system controlled must have significant load diversity that will result in savings through motor speed variation.
