Energy-efficient motors, pumps, and drives can yield considerable savings when optimized and properly sized.
A drive controls the speed of a motor, which rotates a pump or fan to move air or fluid. Proper sizing of motors, pumps, and fans is the most important factor in a system’s overall energy efficiency. Variable frequency drives (VFDs) can often generate significant savings, too. Their load-matching technology allows a motor to run only as fast as needed, saving energy and reducing wear on equipment. The DCSEU offers rebates on VFDs for multiple applications for District businesses and enhanced rebates to affordable housing, clinics, and shelters serving income-qualified DC residents.
The DCSEU offers rebates on VFDs for the following types of applications:
- Supply fans
- Return fans
- Chilled water pumps
- Hot water pumps
- Water source heat pump circulation pumps

All projects must be submitted for pre-approval prior to the purchase of equipment. Applications that are not submitted for pre-approval are not guaranteed to receive rebates from the DCSEU.
“Low-Income Households” are households that have annual incomes equal to or below 80% of the Area Median Income (“AMI”) or 60% of the State Median Income (“SMI”).
"Low-Income Communities" can be classified as Multifamily Buildings, Clinics, or Shelters that serve low-income households. “Low-Income Housing” is defined as the District’s stock of affordable, low-income housing. It is defined as either (a) a building where the owner or occupant meets the definition of “low-income households” listed above, (b) a multifamily building where at least 66% of the households meet the definition of “low-income households” listed above, (c) buildings owned by non-profit organizations or government that meet the definition of “low-income households” listed above, or (d) buildings where there are contracts or other legal instruments in place that assure that at least 66% of the housing units in the building will be occupied by low-income households.
Total rebates are limited to $50,000 per location, per fiscal year for standard market-rate and $100,000 per location, per fiscal year for income-qualified multifamily. View all the Terms and Conditions.
