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.
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
Variable Frequency Drives (VFDs)
|$150 per hp|
|VFDs > 15hp||Custom|
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.
Total rebates are limited to $50,000 per location, per fiscal year.
Projects must involve a facility improvement that results in a permanent reduction in electrical and or/natural gas energy usage (kWh).
Projects that are NOT eligible for rebates through this program include but are not limited to the following:
- Fuel switching (e.g. electric to gas or gas to electric);
- Changes in operational and/or maintenance practices, or simple control modifications not involving capital expenditure;
- On-site electricity generation;
- Projects focused primarily on power factor improvement;
- Projects that involve peak-shifting (time of day savings) (and not kWh savings);
- Renewable energy projects;
Any products installed at a facility must be sustainable and provide 100% of the energy benefits as stated in the application for a period of at least five (5) years or for the life of the product, whichever is less. If the customer ceases to be a delivery-service customer of Pepco Holdings, Inc. and/or Washington Gas Light Co., or removes the products or systems at any time during the five-year period or the life of the product, the customer will be required to return a prorated amount of rebate funds to the DCSEU. Exceptions may apply for customers upgrading to more efficient products at their own expense.
- All equipment must be new; used or refurbished equipment is NOT eligible rebates.
- All installed equipment must meet state, federal, or local codes and requirements.
- Gas equipment installations must be performed by a licensed trade professional in accordance with the manufacturer's instructions and District of Columbia code requirements.
- Projects must be installed on the municipal utility account listed on the application.
Before you purchase your new equipment, make sure it qualifies for DCSEU rebates.
Variable frequency drives (VFDs) are eligible for rebates when installed on motors that control supply fans, return fans, chilled water pumps, hot water pumps, and water source heat pump circulation pumps.
VFDs must be new and cannot replace existing VFDs.
VFDs must be controlled by an automatic signal (such as differential pressure, flow, or temperature).
The following are NOT eligible for VFD rebates: forward-curve fans with inlet guide vanes, variable pitch vane-axial fans, circulation pumps with integral variable speed, and new construction (reach out to email@example.com if you are looking to install VFDs in a new construction building).
