SUBJECT: APPLICATION OF CAPITOL WATER CORPORATION TO REVISE ITS
SCHEDULE NO. 3 PURCHASE POWER ADJUSTMENT RATE, CASE
NO. CAP-W-10-01

On June 11, 2010, Capitol Water Corporation (“Capitol Water” or “Company”) filed
an Application requesting authority from the Commission to change its Schedule No. 3 Purchase
Power Cost Adjustment 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 (“Commission”). Application at 1.
Capitol Water requests that the Commission process its Application through Modified
Procedure and approve the change on less than 30 days’ notice on an interim basis, subject to
refund, effective on July 1, 2010. Id. at 2. Thereafter, Capitol Water requests a final Order
making any changes permanent with an effective date of August 1, 2010. Id.
THE APPLICATION
In its Application, Capitol Water notes that since its last case to establish a new tariff
rate to recover its purchased power costs (CAP-W-09-01), “Idaho Power Company has been
granted a number of changes . . . which increased rates and charges paid by Applicant to Idaho
Power Co. for electric service.” Id.
Capitol Water’s current base rates were established in Case No. CAP-W-08-02 (Order
No. 30762). Id. In Order No. 30762, the Commission approved “a three (3) year average of
1,454,401 KWh of electricity consumption at an average cost of 5.19¢ to establish rates for
Applicant.” Id. The Company states that its total cost of electric power is $75,483.41. Id. A
DECISION MEMORANDUM- 2
recalculation of Capitol Water’s average cost per kWh at Idaho Power’s current rates for electric
power “produces an average cost of 5.52¢ per KWh.” Id. at 2. Capitol Water estimates that this
revised average cost per kWh yields an annual cost for electric power of $80,295 – an increase of
$4,811 or 6%. Id.
Capitol Water requests that it be permitted to replace its “currently approved
Schedule No. 3 Purchased Power Cost Adjustment of 1.45% with a new Purchased Power Cost
Adjustment of 0.81%.” Id. Additionally, Capitol Water seeks to recover $1,000 for its “costs to
review the Idaho Power Company cases, determine their effect on Applicant and prepare and file
this application.” Id.
Capitol Water states that the reduction of the Schedule No. 3 rate is “due to the
change in Applicant’s incremental costs approved in Case No. CAP-W-09-01 that utilized Idaho
Power Company’s PCA rate of 1.4717¢ per KWh” and was “recently reduced to 0.3114¢ per
KWh.” Id.
Capitol Water attached two exhibits to its Application. Exhibit No. 1 lays out the
calculations used by the Company to reach its proposed Schedule No. 3 Purchase Power Cost
Adjustment rate. Exhibit No. 2 is a copy of the Company’s current Schedule No. 3 with
corrections to reflect the proposed changes to the Purchased Power Cost Adjustment. Capitol
Water also attached a copy of its proposed Schedule No. 3 for the Commission’s approval with a
proposed effective date of July 1, 2010.
Capitol Water states that it was “unable to file this application in a timely manner to
meet the Commission’s 30 day notice requirement due to the date Commission Order Nos.
31081, 31091 and 31097 were issued on May 28, [2010].” Id. Consequently, Capitol Water
says that it “was unable to review those orders and the effect on Applicant until after June 1,
[2010].” Id.
Capitol Water assures the Commission that it will issue a notice advising its
customers of its pending Application before the Commission and that the notice will be
“included with customer bills to be mailed July 1, 2010 and by a news release that is being sent
to the Idaho Statesman and the Idaho Business Review newspapers” in conjunction with the
filling of its Application. Id. at 2-3. A copy of the customer notice and news release were filed
as Exhibit Nos. 3 and 4, respectively. Id. at 3.
