    • Have a project site in Oregon.
  2. Select equipment that qualifies for Energy Trust incentives.

    Your trade ally or vendor can help you get started.

  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.

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