10.1 Levelized avoided fuel costs Consistent with the Company's position provided in comments on the 2016 RBIA Report, due to the manner in which fuel costs have been incorporated, the use of levelized fuel costs from the 2014 IRP based on...

AI summary The document discusses the discrepancy between levelized fuel costs used in the 2014 IRP and actual marginal fuel costs experienced by customers. It highlights that the RBIA should reflect the recovery pattern of fuel costs, which are recovered as they are used, unlike future fixed costs. The levelized costs from the 2014 IRP are significantly higher than actual and projected marginal fuel costs.

AI summary NS Power argues that the current RBIA model used by EfficiencyOne does not accurately reflect the variability in bill and rate impacts among rate classes. They propose separating fuel cost savings from fixed cost savings or losses to improve the accuracy of the RBIA results and better reflect the differences in cost causation between rate classes.
