NEWS RELEASE: Idaho Public Utilities Commission sets public comment deadline on Avista
application to increase surcharge rate for electric customers

BOISE (Aug. 19, 2021) – The Idaho Public Utilities Commission is accepting public comment
until Sept. 9 on an application from Avista to increase its annual Power Cost
Adjustment surcharge rate from 0.015 cents per kilowatt hour to 0.251 cents per kilowatt hour.

Avista, which serves electric and natural gas customers in northern Idaho, reported higher overall
power supply expenses than are included in electric retail rates. Avista said increased power
supply expenses that were driven primarily by increases in thermal generation and changes in
natural gas generation resulted in supply expenses of $12.5 million. Avista also said the
surcharges were offset by favorable net purchases and transmission expense for a $4.7 million
rebate.

If Avista’s application is approved, electric residential customers using an average of 896
kilowatts per month would see monthly bills increase 2.5 percent, from $85.63 to $87.74. The
company has requested an effective date of Oct. 1, 2021.

The annual Power Cost Adjustment tracks changes in Avista’s hydroelectric generation,
secondary prices, thermal fuel costs and other changes in power contract revenues and expenses.
