ORDER NO. 34866

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 the rounded interest rate on customer deposits during the next calendar year.
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, 2019 through
October 31, 2020, is 0.62%. Accordingly, public utilities must pay 1.0% annual interest on all
customer deposits for calendar year 2021.
O R D E R
IT IS HEREBY ORDERED that 1.0% annual interest shall be paid during calendar
year 2021 on customer deposits held by gas, electric, water, and telephone companies subject to
this Commission’s jurisdiction under IDAPA 31.21.01.106 and 31.41.01.104. The Commission
Secretary shall serve this Order upon all public utilities operating within Idaho.
IT IS FURTHER ORDERED that the rate on deferred accounts using the customer
deposit rate during calendar year 2021 shall be 1.0%.
THIS IS A FINAL ORDER. Any person interested in this Order may petition for
reconsideration within twenty-one (21) days of the service date of this Order. Within seven (7)
days after any person has petitioned for reconsideration, any other person may cross-petition for
reconsideration. See Idaho Code §§ 61-626 and 62-619.
ORDER NO. 34866 2
DONE by Order of the Idaho Public Utilities Commission at Boise, Idaho this 10th day
