Instead of meeting its annual renewable resource target in WAC 480-109-020
, a utility may make one of three demonstrations.
(1) A utility may invest at least four percent of its total annual retail revenue requirement on the incremental costs of eligible renewable resources, renewable energy credits, or a combination of both. The incremental cost of an eligible renewable resource is the difference between the levelized delivered system cost of the eligible renewable resource and the levelized delivered cost of an equivalent amount of reasonably available nonrenewable resource. The system analysis used will be reasonably consistent with principles used in the utility's resource planning and acquisition analyses.
(2) A utility may demonstrate that events beyond its reasonable control that could not have been reasonably anticipated or ameliorated prevented it from meeting the renewable energy target. Such events may include weather-related damage, mechanical failure, strikes, lockouts, or actions of a governmental authority that adversely affect the generation, transmission, or distribution of an eligible renewable resource owned by or under contract to a qualifying utility.
(3) A utility may demonstrate all of the following:
(a) Its weather-adjusted load for the previous three years on average did not increase.
(b) After December 7, 2006, all new or renewed ownership or purchases of electricity from nonrenewable resources other than daily spot purchases were offset by equivalent renewable energy credits.
(c) It invested at least one percent of its total annual retail revenue requirement that year on eligible renewable resources, renewable energy credits, or a combination of both.
