(1) WREGIS is the renewable energy credit tracking system for purposes of verification of RECs under chapter 19.285 RCW.

(2) Upon request by a utility, the department may approve a special purpose renewable energy credit tracking system for the generation of any specific generating facility acquired through ownership or contract by a utility prior to January 1, 2015, if the utility certifies that it would be impractical or financially burdensome to track the generation of the facility using WREGIS. The approval of a special purpose tracking system may include limitations or conditions on the transfer of RECs. All references to WREGIS in this chapter include such approved special purpose tracking systems.
