"Caps and limits" are defined as follows:

(1) "Annual incentive limits" means the annual limits on total incentives paid per person, business, or household for a given fiscal year of electricity generation from the four project types described in chapter 36, Laws of 2017, 3rd sp. sess. (ESSB 5939). Each incentive recipient may qualify for payments up to the incentive cap within each project type. However, incentive recipients who have multiple projects within one project type are subject to the cap for the applicable project type. These caps are as follows:

(a) Residential-scale systems: Five thousand dollars;

(b) Commercial-scale systems: Twenty-five thousand dollars;

(c) Shared commercial solar projects: Up to thirty-five thousand dollars per year per project participant, as determined by the terms specified in chapter 36, Laws of 2017, 3rd sp. sess. (ESSB 5939); and

(d) Community solar projects: Five thousand dollars per project participant.

(2) "Utility credit cap" means that the maximum annual incentives paid by an electrical utility may not exceed one and one-half percent of the businesses' taxable power sales generated in calendar year 2014 and due under RCW 82.16.020 (1)(b) or two hundred fifty thousand dollars, whichever is greater, up to the utility's public utility tax liability.

(3) "Project type cap" has the following two meanings in this chapter:

(a) For commercial-scale systems, the project type cap is twenty-five percent of the remaining funds for credit available to a utility as of July 1, 2017; and

(b) For community solar and shared commercial solar projects combined, the project type cap is fifty percent of the remaining funds for credit available to a utility as of July 1, 2017.

(4) "Incentive rate limit" for shared commercial solar project participants means that the incentive rate must not exceed the difference between the levelized cost of energy output and the participant's retail rate.

(5) "Total program limit" means that the total incentive payments made under this program (in this chapter) may not exceed one hundred ten million dollars.
