Authorizes a public utility district to organize, administer, and own a community solar project.

Requires a district-owned solar energy system to be voluntarily funded by the district's ratepayers where, in exchange for their financial support, the district gives contributors a payment or credit on their utility bill for the value of the electricity produced by the project.

Includes public utility districts in the definition of "utility," in chapter 82.16 RCW, for purposes of community solar projects.
