Variable Frequency Drives

The Delmarva Power C&I Energy Savings Program has helped many of our customers save energy and money by providing cash incentives for the purchase and installation of Variable Frequency Drives (VFDs). The Program can help you meet your energy savings goals and reduce your operating costs as well.

VFDs provide opportunities for energy savings in many motor-driven systems including:
  • Building Exhaust Fans
  • Make-up Air Fans
  • HVAC Return Air Fans
  • Heating Water Pumps
  • Cooling Tower Fans
  • HVAC Supply Air Fans
  • Chilled/Condenser Water Pumps
  • Water Source Heat Pump Circulating Loop Pumps

By controlling motor speed and torque (twisting force) to accommodate system load variations, VFDs coupled with NEMA premium-efficiency motors offer greatly enhanced system control and efficiency.

Refer to the Variable Frequency Drives Application for eligible measures and incentives, technical details and terms and conditions. .

Alternative VFD incentives may be available for VFD applications on motors larger than 200 hp and elsewhere when system efficiencies are improved by coupling VFDs with non-HVAC motor-driven systems, including:
  • Air Compressor
  • Process Pumps
  • Process Fans
  • Process Machinery
  • Other Processes

Please contact the Program office for more details.

The program is not accepting applications at this time. Review the most current Program Update for additional details.
