REQUEST:
The direct testimony of Robert Lafferty includes an Exhibit No.6, Schedule 10 that appears to be
an analysis of estimated revenue requirement impacts of three of the proposals considered in the
RFP. The analysis appears to have been done subsequent to a decision being made by Avista to
select the CS II proposal. There appears to be no narrative discussion of Schedule 10 in Mr.
Lafferty s testimony. Please discuss the purpose of the analysis shown in Schedule 10 and any
conclusions Avista reached based on the results of that analysis.
RESPONSE:
Beyond what is included in Robert Lafferty s Pre-filed Direct Testimony, Exhibit No.
Schedule No.8 describes in more detail the resource selection process. The evaluation of
financial rate impacts and conclusions are explained on pages 3 - 4 of Schedule No.8 which
references the revenue requirement analysis contained in Exhibit No., Schedule No. 10.
