Avista Makes Annual Price Adjustment Filing in Idaho
Request would result in higher electric prices effective May 1, 2026.
SPOKANE, Wash. — February 13, 2026, 4:05 p.m. PDT: Avista (NYSE: AVA) has made an
annual rate adjustment filing with the Idaho Public Utilities Commission (IPUC or Commission) that if
approved, is designed to increase overall electric revenues by approximately$25.2 million or 7.4%effective
May 1, 2026. This filing has no impact on Avista's earnings.
The proposed rate adjustment modifies the level of funding for Avista's electric energy efficiency programs.
This adjustment aligns the amount that is collected in customer rates with the actual costs to operate the
programs. Avista's energy efficiency programs are designed to provide a financial incentive or rebate for
cost-effective energy efficiency measures. The rate changes proposed reflect the required level of funding
needed to operate the programs in the coming year, and to recover costs spent in 2025 that exceeded the
levels included in rates. The electric rate adjustment is designed to increase the amount collected from
customers by$25.2 million or 7.4%.
Customer Bills Resulting from these Filings
If the electric Energy Efficiency filing is approved, residential electric customers in Idaho using an average
of 939 kilowatt hours per month would see their monthly bills increase from$115.54 to$124.44, an increase
of $8.90 per month, or approximately 7.7%. The requested electric rate change by rate schedule is as
follows:
Residential Service- Schedule 1 7.4%
General Service- Schedules 11 & 12 7.3%
Large General Service-Schedules 21 &22 7.1%
Extra Large General Service - Schedule 25 7.5%
Extra Large General Service - Schedule 25P 7.9%
Pumping Service- Schedules 31 & 32 7.2%
