Beginning July 1st, 2017, under Revised Code of Washington Title 82, Chapter 82.16.170 (RCW 82.16.170), the state of Washington granted community solar administrators the ability to organize and administer community solar projects. Stipulations surrounding community solar projects include a maximum direct current (DC) nameplate capacity of 1 megawatt (MW), as well as a minimum of 10 participants or 1 per 10 kW DC nameplate capacity, whichever is greater. Projects exceeding 500 kW will be subject to a standard interconnection agreement. Members participating in any community solar project must be customers of the utility providing service at the site. Additional organizational and administrative information can be found within the above mentioned RCW chapter.

To incentivize the creation of community solar projects, RCW 82.16.165 details avenues community solar administrators can pursue to obtain incentives through the Washington State University Extension Energy Program (WSUEEP). Incentives for community solar projects are not to exceed $5,000 per project participant, with payments for fiscal year 2021 being $0.10/kWh. Funding for community solar or shared commercial solar projects will end for any fiscal year if 50% or more of the WSUEEP funds for credit have been allocated to community solar or commercial solar projects. The WSUEEP fund is not to exceed $110 million.

On March 12th, 2020, the Washington legislature passed HB 2248 - 2019-20, establishing increased community solar incentives for low-income participants, to be awarded to the community solar administrator. This increased incentive is not to exceed $20,000 and is intended to recover administrative fees associated with qualifying participants.
