Washington Administrative Code › Title 480 - Utilities and Transportation Commission › Chapter 480-109 - Electric companies-Acquisition of minimum quantities of conservation and renewable energy as required by the Energy Independence Act (chapter 19.285 RCW) › Section 480-109-210 - Renewable portfolio standard reporting

Current through Register Vol. 24-14, July 15, 2024
(1)
Annual report.
On or before
			 every June 1st, each utility must file an annual renewable portfolio standard
			 report with the commission and the department detailing the resources the
			 utility has acquired or contracted to acquire to meet its renewable resource
			 obligation for the target year.
(2)
Annual report contents.
The annual renewable portfolio standard
			 report must include the utility's annual load for the prior two years, the
			 total number of megawatt-hours from eligible renewable resources and/or
			 renewable resource credits the utility needed to meet its annual renewable
			 energy target by January 1st of the target year, the amount (in megawatt-hours)
			 of each type of eligible renewable resource used, and the amount of renewable
			 energy credits acquired. Additionally, the annual renewable portfolio standard
			 report must include the following:
(a)
Incremental cost calculation.
To calculate its incremental cost, a
			 utility must:
(i) Make a one-time calculation
			 of incremental cost for each eligible resource at the time of acquisition or,
			 for historic acquisitions, the best information available at the time of the
			 acquisition:
(A)
Eligible resource
			 levelized cost.
Determine the levelized cost of each eligible resource,
			 including integration costs as determined by the utility's most recently
			 completed renewable resource integration study, using the utility's
			 commission-approved weighted average cost of capital at the time of the
			 resource's acquisition as the discount rate;
(B)
Eligible resource capacity
			 value.
Identify the capacity value of each eligible renewable resource
			 as calculated in the utility's most recent integrated resource plan
			 acknowledged by the commission;
(C)
Noneligible resource selection.
Select and document the
			 lowest-reasonable-cost, noneligible resource available to the utility at the
			 time of the eligible resource's acquisition for each corresponding eligible
			 resource;
(D)
Noneligible
			 levelized energy cost.
For each noneligible resource selected in
			 (a)(i)(C) of this subsection, determine the cost of acquiring the same amount
			 of energy as expected to be produced by the eligible resource, levelized over a
			 time period equal to the facility life or contract length of the eligible
			 resource and at the same discount rate used in (a)(i)(A) of this
			 subsection;
(E)
Noneligible
			 levelized capacity cost.
Calculate the levelized capital cost of
			 obtaining an equivalent amount of capacity provided by the eligible resource,
			 as determined in (a)(i)(B) of this subsection, from a noneligible resource.
			 This cost must be levelized over a period equal to the facility life or
			 contract length of the eligible resource and at the same discount rate used in
			 (a)(i)(A) of this subsection. To make this calculation, a utility must use the
			 lowest-cost, noneligible capacity resource identified in its most recent
			 integrated resource plan acknowledged by the commission. However, if a utility
			 determines that cost information in the integrated resource plan is no longer
			 accurate, it may use cost information from another source, with documentation
			 of the source and an explanation of why the source was used;
(F)
Calculation.
Determine the
			 incremental cost of each eligible resource by subtracting the sum of the
			 levelized costs of the noneligible resources calculated in (a)(i)(D) and (E) of
			 this subsection from the levelized cost of the eligible resource determined in
			 (a)(i)(A) of this subsection. The result of this calculation may be a negative
			 number;
(G)
Legacy
			 resources.
Any eligible resource that the utility acquired prior to
			 March 31, 1999, is deemed to have an incremental cost of zero.
