Dear Ms. Hanian:
RE: AVU-E-I 5-05/AVU-G-1 5-01
Electric and Natural Gas Fixed Cost Adjustment Mechanism
Ouarterly Report
On February 14,2018, Avista provided its Electric and Natural Gas Fixed Cost Adjustment Mechanism
Quarterly Report for 4m quarter 2017 confidentially as the Company had not at that time released its
earnings for 2017 . The Company's 2017 earnings have since been released and the 4th quarter Electric
and Natural Gas Fixed Cost Adjustment Mechanism Quarterly Report is no longer confidential. Please
supplement the February 14 filing with this unrestricted version.
Attached for filing with the Commission is an electronic copy of Avista's Electric and Natural Gas Fixed
Cost Adjustnent Mechanism Quarterly Report.
The report consists of spreadsheets showing the monthly revenue deferral calculations for October,
November and December 2017. In addition, Avista has provided illustrative revenue deferral
calculations for the non-residential electric group on a rate schedule basis as required in the Settlement
Stipulation approved by the Commission in the above referenced docket. The other electric and natural
gas groups consist ofonly one rate schedule each and therefore would not change under the rate schedule
assumption.
Also included in the report are the monthly general ledger balances resulting from the deferral and
amortization activity during the 4th quarter of 2017.
Questions regarding this filing should be directed to Tara Knox at [phone].
