SUBJECT: APPLICATION OF CAPITOL WATER CORPORATION FOR
AUTHORITY TO INCREASE ITS SCHEDULE NO. 3 PURCHASE
POWER ADJUSTMENT RATE, CASE NO. CAP-W-12-01

On June 15, 2012, Capitol Water Corporation (“Capitol Water” or “Company”) filed
an Application to increase its Schedule No. 3 Purchase Power Adjustment Rate to “recover the
Company’s cost of electricity related to Idaho Power Company’s electric rate schedules that have
been approved by the Idaho Public Utilities Commission (‘IPUC’ or ‘Commission’).”
Application at 1.
THE APPLICATION
In its Application, Capitol Water states that the proposed “change is necessitated by
Idaho Power Company’s recent changes in the rates and charges for electric service to Capitol
Water Corporation.” Id. The Application references “the effect of Idaho Power Company’s
pending [, now concluded,] Case No. IPC-E-12-14 regarding the Langley Gulch power plant.”
Id.
In its Application, Capitol Water estimates that, once the costs of the Langley power
plant case are included, its rates will rise from its current average rate of 5.58¢ per kWh to 5.87¢
per kWh. Id. at 2. The Company believes that its total cost of electric power will increase from
$75,483.41 to $81,136. Id. This amounts to “an increase in annual electric power cost of $5,653
or 7.49% more than included in Applicants base water rates.” Id. Further, “when the estimated
affect of the Langley power plant case are included, Applicants average KWh cost of 5.87¢ per
DECISION MEMORANDUM 2
KWh results in an annual cost to Applicant of $85,418.” Id. This amounts to an annual increase
in electric power costs of $9,934 or 13.161% from Capitol Water’s current base water rates. Id.
Capitol Water also requests recovery of $1,200 as costs associated with the review of
the Idaho Power Company cases, ascertaining their effect on the Company, prepare and file the
Application, and respond to inquiries regarding the Application. Id. Applicant proposes an
increase of the currently approved Schedule No. 3 Purchased Power Cost Adjustment Rate from
.37% with a new Purchased Power Cost Adjustment Rate of 1.71%. Id.
Capitol Water has attached Exhibit No. 1 demonstrating its calculations at Idaho
Power Company’s [pre-Langley Gulch] approved rates. Id. Exhibit No. 2 demonstrates the
same calculation but incorporates the anticipated effect of the Idaho Power Company Langley
Gulch power plant case on its rates. Id. Exhibit No. 3 is a copy of the Company’s current
approved Schedule No. 3 in legislative format that shows the proposed change to the Purchased
Power Cost Adjustment Rate. Id.
The Company’s Application also included a revised Schedule No. 3 with an effective
date of August 1, 2012. Id. at 3. Capitol Water provided workpapers showing its calculations
for Staff review. Id.
The Company states that it has informed its customers of its Application to the
Commission through a customer notice included in customer bills mailed on July 1, 2011 and via
a news release to the Idaho Statesman and the Idaho Business Review newspapers
contemporaneous with this filing. Id., Exhibit Nos. 4 and 5.
Capitol Water requests that the Commission process its Application pursuant to
Modified Procedure with a proposed effective date of August 1, 2012. Id.
COMMISSION DECISION
Does the Commission wish to process Capitol Water’s Application for an increase in
its rates and charges for water service through Modified Procedure with a 21-day comment
period?
