Washington State production incentive program

The Washington State Renewable Energy System Incentive Program is a production-based financial incentive for customers with solar, wind, and bio-digester generating systems. PSE voluntarily administers this state incentive to qualified customers. In order for a customer-generator to participate they must:

  • Be a PSE customer with a valid interconnection agreement with the PSE for the operation of their grid-connected renewable energy system.
  • Have a system that includes production metering capable of measuring the energy output of the renewable energy system.
  • Be certified (as named on the PSE account) by the Washington State Program Administrator as eligible for annual incentive payments.

Annually, PSE will measure and report the kilowatt-hours generated by participants’ renewable energy systems and make incentive payments to eligible customers as determined by the Washington State Program Administrator. Individual participant eligibility for a given rate, term, payment limit, and incentive payment amounts will be determined by the Washington State Program Administrator.


Please be aware that PSE cannot guarantee the availability of the Washington Production Incentive Program funds. Eligibility in the state incentive program is determined by the WSU Energy Program. Customers can submit an application to this program only after their renewable energy system has been installed and passed its final electrical inspection. Per state law, WSU Energy Program can only obligate up to $110 million dollars in incentive payments to participants statewide. PSE’s best estimate is that this limit could be reached as early as the end of 2018, and when it is, WSU will stop accepting applications to the program.

If earning the state incentive plays a crucial part in your decision to invest in solar energy, we encourage you to learn more about the availability of incentives at energy.wsu.edu/RenewableEnergySystemIncentiveProgram and discuss the risks and project timeline with your installer.
