    Energy Trust provides cash incentives to Oregon businesses for energy-efficiency and renewable energy projects. To qualify, you must:

    • Be served by Portland General Electric or Pacific Power and contribute to the public purpose charge. Check your utility bill or contact us if you have questions.
    • Have a project site in Oregon.
  2. Select equipment that qualifies for Energy Trust incentives.

    Your trade ally or vendor can help you select equipment that qualifies for Energy Trust incentives.

  3. Receive an incentive offer from Energy Trust.

    Review the offer, provide your utility account number, signed W-9, mailing address, site address and estimated project completion date. You must return the signed incentive offer to the Energy Trust contact listed on the form before ordering or purchasing the equipment.

  4. Purchase and install the equipment.

    After you return the signed incentive offer, then purchase and install the equipment.

  5. Sign the Project Completion Form.

    Once your project is completed, you will receive a Project Completion Form from Energy Trust, which must be returned with your invoice(s) for the equipment purchased.

  6. Receive your incentive.

If you have a pump that operates at a range of different flows throughout the year or draws from a well with a depth that varies significantly, a Variable frequency drive (VFD) could make sense for your farm. With a VFD, the desired pressure and flow are produced by controlling the pump speed, rather than throttling the discharge flow or using a bypass to maintain target flow conditions.

Customers may receive cash incentives up to $250,000 per site, per year. Incentives are subject to funding availability and may change.

See incentive amounts available for irrigation pump VFDs outlined in the table below. Cash incentives are calculated based on operating hours and usage.

Irrigation Pump VFD $0.30 per kWh saved, up to 70% of eligible project cost
