Variable Frequency Drive Commercial Rebates

  • Rebate amount: $24 per hp (all sizes)

Commercial Rebate items, amounts and efficiency requirements are changing effective April 1, 2018. Click here for a preview of the new rebate structure.

Variable frequency drives (VFDs) offer commercial properties better control of energy usage. Rather than the "all-on or all-off" approach used in more traditional motors and equipment, variable frequency drives only require the amount of energy necessary to run at the time, providing a more moderated use of power.
