RE: APPROVAL OF MODIFICATIONS TO AVISTA CORPORATION
NATURAL GAS TARIFFS; TARIFF ADVICE N0.17-01-G
BACKGROUND
On January 3, 2017, Avista Corporation ("Avista" or "Company"} submitted a
"housekeeping filing" of its natural gas tariffs. The filing updates components noted as "Other
Charges" on base rate tariffs. The proposed changes are a result of the recently approved PGA
filing which affected Schedules 150 (Purchase Gas Cost Adjustment), 155 (Gas Rate
Adjustment), and 191 (Energy Efficiency Rider Adjustment) Case No. A VU-G-16-02.
Additionally, the Company is requesting to withdraw Schedule 197 (Rebate of Natural Gas
Earnings Test Deferrals) because the rebate expired December 31, 2016. All references to
Schedule 197 will be removed. Base rates do not change as a result of this filing.
The Company is also correcting a typographical error in the WACOG (Weighted
Average Cost of Gas) section of Schedule 150. This correction is being made to depict the actual
rate customers are billed. The Company has requested an effective date of February 3, 2017.
STAFF RECOMMENDATION
Staff has reviewed the Company's filing, verified that proposed changes do not change
base rates, validated all calculations, and confirmed that rates in the proposed tariff sheets align
with the most recent PGA Case No. AVU-G-16-02. Staff recommends Commission approval of
the Company's proposed changes to Schedules 150, 155, and 191 and withdrawal of Schedule
197.
