The Commission's Customer Relations Rules for Gas,Electric and Water Utilities(IDAPA
31.21.01.106)and the Customer Relations Rules for Telephone Companies(IDAPA 31.41.01.104)
require utilities to pay interest on customer deposits. To determine the interest rate, the
Commission calculates the 12-month average interest rate for one-year treasury bills for the
previous November 1 through October 31, rounded to the nearest whole percent. Public utilities
must pay interest on customer deposits during the next calendar year at the rate determined by the
applicable Commission rules.
Using the weekly rates as posted by the U.S. Department of Treasury, the average interest
rate for one-year treasury bills for the 12-month period from November 1, 2023, through October
31, 2024, is 4.83%. Accordingly, public utilities must pay 5.0% annual interest on all customer
deposits for calendar year 2025. This interest rate is equal to the interest rate paid in 2024. See
Order No. 36000.

2025 on customer deposits held by gas, electric, water, and telephone companies subject to this

Secretary shall serve this Order upon all public utilities operating within Idaho.

rate during calendar year 2025 shall be 5.0%.
