Renewable Energy System Incentive Program

This program is now fully subscribed.

The WSU Energy Program’s Renewable Energy System Incentive Program (RESIP) is on track to end in the winter of 2027, following its full subscription in 2019. RESIP authorizes 96 months (eight years) of annual payments to residential and commercial utility customers for energy generated by certified renewable energy systems. These systems include solar photovoltaic (PV), wind, and anaerobic digester systems under the original 2017 legislative mandate (ESSB 5939).  

Focus Areas

  • Incentive analysis: We provide a review of the reported generation of energy systems to determine eligibility for payment. 
  • Utility coordination: Our team works with utilities that provide energy system generation data and system transfer notifications or verifications. 
  • System owner coordination: We collect certification transfers from new owners and answer new owner questions. 

Important Update for RESIP Participants

If you have a certified solar, wind, or anaerobic digester system, note that changes in homeownership or system additions must be reported to the WSU Energy Program at ep.solarprogram@wsu.edu to ensure uninterrupted payments.
