REQUEST:
On page 8, lines 5-8 of the Application, Avista states that "The estimated FCA revenue shortfall
associated with energy efficiency programmatic savings is $0.1 million residential and $0.01
million non-residential." Please provide support for these calculations including Excel workbooks
with formulas intact. Please provide the therm reductions on which the above dollar savings are
based. Also, please reconcile these results to the Company's pending 2016 Demand-Side
Management (DSM) report and any previous DSM reports that apply.
RESPONSE:
Please see Staff PR_004 Attachment A that contains the calculation of the estimated impact of the
FCA surcharge drivers. The revenue impact estimation is calculated on page l, and the DSM
programmatic usage savings from the 2014, 2075, and draft 2016 DSM annual reports are
identified on page 3. As the Company's natural gas energy efficiency measures were suspended
during 2014 and2015, no savings were reported for those years. The 2016 savings as reported on
table ES-2 on page 2 of the executive summary of the draft 2016 DSM annual report were used in
their entirety to estimate the cumulative savings reflected in2016 actual usage that was not part of
the 2014 test year usage used to set the FCA Base in Case No. AVU-G- I 5-01 .
