Eligibility & Incentive Rates


Renewable energy systems eligible for incentives under the new incentive program include solar photovoltaic energy systems, anaerobic digesters, and wind generators used for producing electricity.

The system categories are as follow:

  • Residential-scale system: Combined nameplate capacity at a single site of 12 kWdc or less.
  • Commercial-scale system: Combined nameplate capacity greater than 12 kWdc.
  • Shared commercial solar project: Owned or administered by an electric utility with a combined nameplate capacity greater than 1 MWdc and up to 5 MWdc.
  • Community solar project: No larger than 1,000 kWdc.

Incentive Rates

Incentive rates for the new program are based on the fiscal year that the system is certified, project type, and made-in-Washington bonus. Incentive rates are listed in the chart below. This is a production-based incentive. Your utility will report annual production of your system to the WSU Energy Program team. We will then calculate your incentive for that fiscal year and share this with your utility, who will then provide incentives payments by Dec. 15 of that fiscal year.

A fiscal year runs from July 1 to June 30. We are currently in fiscal year 2018 until June 30, 2018. Certification of a new system may take up to 30 days from date of submission. We encourage applicants to submit your application when the renewable energy system passes final electrical inspection.
