Process VFDs
A Variable Frequency Drive (VFD) controls the speed of electric motors and is used in a wide range of industrial processes to optimize energy efficiency and improve process control.
Motors can use more energy than any other piece of equipment in your facility — running pumps, fans, mixers, extruders, grinders and other industrial equipment. But many motors run at a constant speed even at times of low demand, wasting energy and wearing out your equipment more quickly.
Variable frequency drives (VFDs) operate at lower speeds during periods of lower demand to help motors operate more efficiently and reduce wasted energy.
Financial Incentives for Process VFDs
Financial incentives to install VFDs on existing motors could cover up to 80% of your total project cost. Individual motors over 500 hp may be eligible as a Custom project.
| INCENTIVE TYPE | INCENTIVE AMOUNT |
| Fans and Pumps (2,000+ hours per year) | Private Sector: $125/hp controlled (up to 80% of project cost) Public Sector: $160/hp controlled (up to 80% of project cost)* |
| Fans and Pumps (500-1,999 hours per year) |
Private Sector: $40/hp controlled (up to 80% of project cost) Public Sector: $50/hp controlled (up to 80% of project cost)* |
| Custom | $0.16-$0.20/kWh saved |
| *Estimated savings based on average cost per kWh/therm and depends on age and condition of current equipment. | |
