Motors + Drives

Motors and drives keep the wheels of progress moving forward for many Oregon businesses. Energy Trust offers incentives for Green Rewinds that can restore or maintain your motor's original efficiency, as well as energy-efficient variable speed drives.

Energy Trust Incentives

Variable Frequency Drives

A variable frequency drive, VFD, is an electronic motor control which adjusts motor speed to match variable system requirements. They are reliable, universally available, and can be added to motors where system demand or load varies. A VFD can reduce a system’s energy costs by 35% or more.  

Non-energy benefits of VFD’s:

  • Reduce stress on equipment by lowering operating speeds
  • Create a soft start which eliminates the stress across the line starts
  • Decrease facility noise levels due to lower motor operating speeds, which can translate into a safer work environment

Energy Trust offers cash incentives of $0.25/annual kilowatt hour, up to 50 percent of the project cost for adding automatic flow gates or fan VFD controls to an existing dust collection system.

Need to rewind a motor? A Green Rewind can restore or maintain your motor’s original efficiency. Energy Trust has teamed with the Green Motors Practices Group to provide instant rebates for Green Rewinds provided by member service centers. Visit for more information. To participate, you need to have the motor rewound by a member service center (list available on the Green Motors Practices Group website). Incentive is $1/hp and is given in the form of an “instant discount” on the rewind invoice. No forms are required.


Energy Trust provides cash incentives to Oregon businesses for energy efficiency and renewable power projects. To qualify, you must be an Oregon customer of Portland General Electric or Pacific Power.

Incentives are not intended to influence consumer decisions on fuel sources.

Work with your vendor or find and contact an Energy Trust trade ally contractor or vendor in your area to learn more, upgrade your dust collection system and apply for cash incentives.
