WAC 194-37-160

Documentation of financial cost cap—Current information and timeline.

By January 1 of the first target year that a utility fulfills its renewable energy requirements under RCW 19.285.050, the utility shall select one of the following methodologies for documenting the incremental cost of all eligible renewable resources acquired thereafter by that utility:
(1) Annual update methodology. In each year that a utility fulfills its renewable energy requirements by complying with the cost cap identified in RCW 19.285.050 it must document its calculations no later than January 1 of the target year. The utility will use the most current information available to the utility within twelve months prior to the initial documentation of the cost cap pursuant to WAC 194-37-170 through 194-37-190. The utility will update this documentation in its June 1 report submitted pursuant to RCW 19.285.070. These annual updates of costs, based on the most current information available, apply to both the eligible renewable resource and the substitute resource.
(2) Permanent one-time methodology. For each new investment in an eligible renewable resource, a utility shall perform a one-time calculation of the levelized incremental cost pursuant to WAC 194-37-170 through 194-37-190. The levelized incremental cost shall be a single annual value expressed in real, constant-year dollars. The levelized incremental cost for each eligible renewable resource project or purchase, calculated through this one-time analysis in the year of acquisition, shall be allowed to inflate utilizing the Producer Price Index over the life of the eligible renewable resource after the initial calculation. The utility will include a determination of incremental cost for each new investment in an eligible renewable resource and inflation-adjusted incremental costs for previous eligible renewable resource investments in its June 1 report submitted pursuant to RCW 19.285.070, beginning in the year the utility complies with the cost cap identified in RCW 19.285.050.
