II. BACKGROUND
The electric Residential and Farm Energy Rate Adjustment results from an
Agreement between the Company and Bonneville Power Administration (BPA). The
Residential Exchange Program provides a share of the benefits of the federal Columbia
River power system to the residential and small-farm customers of the six investor-owned
utilities of the Pacific Northwest, including Avista.

0.3701, per kilowatt-hour rate credit. This rate was approved by the Idaho Public Utilities
Commission effective October 1,2021in OrderNo. 35181.
The proposed rate credit of 0.3800 per kilowatt-hour is designed to pass through
approximate[ $a.9 million which represents the Idaho portion of the annual level of BPA
benefits, offset by the over-refunded balance from the prior year, starting in October 2022.
The level of BPA benefits is consistent with what is currently being passed back to
customers in rates today. That amount, however, is offset by an over-refunded balance
from the prior year of approximately $0.2 million, which is due to actual usage being higher
than what was projected in the Company's 2021 filing. The table below details the year
over year differences between the benefit included in current rates and the proposed benefit
included in this filing.

The Company is therefore proposing an overall decrease of $0.2 million or O.lYo
for qualiffing customers. The change in rate credit has no effect on Avista's net income.
