RE:ANNUAL DETERMINATION OF THE INTEREST RATES ON
DEPOSITS COLLECTED FROM CUSTOMERS FOR THE CALENDAR
YEAR 2022;CASE NO.GNR-U-21-02.
Every year the Commission sets the interest rate to be paid on customer deposits for the
next calendar year.Rule 106 of the of the Customer Relations Rules for Gas,Electric and Water
Utilities provides:“the Commission will determine the twelve-month average interest rate for
one-year Treasury Bills for the previous November 1 through October31,round that rate to the
nearest whole percent...”.(IDAPA 31.21.01.106 and IDAPA 31.41.01.104).This average
interest rate is 0.08%as shown on Attachment A.Commission Order No.32109 determined
zero is not a whole interest rate and paying some level of interest on deposits is fair.Staff
recommends the rate be rounded to the nearest whole percent and be set at 1%for the calendar
year 2022.a 1%decrease from the prior year.
Rule 9 of the Customer Relations Rules for Gas,Electric and Water Utilities allows the
Commission on its own motion to approve a deviation of the rule in unusual circumstances
(Exemption from Rules,IDAPA 31.21.01.009).Staff believes the current low interest rates
represent an unusual situation.Fairness supports the belief that payment of zero interest is not
the intent behind the rule stating “interest will be payable on all deposited amounts.”Id.The
chart on Attachment B shows the interest rates since 1990 and the Order numbers approving
those rates.
