On June 14, 2016, Capitol Water Corporation applied to the Commission for
authority to adjust its Schedule No. 3 Purchased 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." Application at 1. Capitol Water
proposed an effective date of August 15, 2016.
On June 21, 2016, the Commission issued a Notice of Application, Notice of
Modified Procedure, and Order. Order No. 33545. Commission Staff reviewed the Application
and filed written comments on July 19, 2016. Capitol Water filed a timely reply. The
Commission received one written comment from a Capitol Water customer supporting the
request.
BACKGROUND
In 2009, the Commission approved Capitol Water's request to implement a purchased
power cost adjustment (PPCA) mechanism. Order No. 30881. The intent of the PPCA is to
provide the Company with a way to adjust for increased or decreased purchased power costs.
The current mechanism assumes that the amount of electricity consumed by the Company is
stable over time, and that electricity costs are affected only by changes in electricity rates
charged by Idaho Power.
In approving the PPCA, the Commission adopted an average use of 1,454,401 kWh1
of electricity consumption, at an average cost of 5.19¢ per kWh, resulting in a total electric
power cost rate of $75,483, which is included in base water rates. Id. The Company's Schedule
3 takes in or offsets the difference between power costs that are in base rates and actual projected
power costs to be paid by the Company. The Company's current Schedule 3 PPCA rate is
4.25%.
1 Since its implementation in 2009, the PPCA has utilized an electric use value based on a normalized average of the
Company's 2006-2008 consumption.
ORDER NO. 33565 1
PROPOSED ADJUSTMENT
The Company claims that Idaho Power's current rate of 7.15¢ per kWh produces an
annual cost for electric power of $103,972, a difference of $28,488 above what is in base rates.
Application at 2. Factoring in $1,100 associated with the preparation and filing of the
Application, the Company proposes an increase of 0.29%, bringing the PPCA rate to 4.54% to
generate a revised PPCA of $29,588. The Company notes that the electricity rates affecting its
power costs were approved by the Commission, and also requests that "the Commission take
official notice of Idaho Power Company rates and charges currently in effect and on file." Id at
1.
In support of its request, the Company includes with its Application a worksheet
detailing its calculations (Exhibit No. 1), a copy of the proposed Schedule No. 3 in legislative
format (Exhibit No. 2), a sample customer notice that will be included in the July billing (Exhibit
No. 3), and an Idaho Statesman and Idaho Business Review news release. Id. (Exhibit No 4).
STAFF COMMENTS
Staff reviewed the Application and attachments and found that the Company's
description of increasing power rates are accurate and its case preparation costs are reasonable.
Consequently, Staff recommended the Commission approve those requests. However, Staff also
recommended modifications be made to the Company's request, and certain changes be made to
billing statements, and notice in future PPCA filings. Specifically, Staff recommended an
adjustment to the energy consumption number, and some administrative changes to better clarify
to customers the PPCA charges.
1. Energy Consumption Levels
Staff evaluated the historical normalized three-year average of 1,454,401 kWh used
to calculate annual power supply costs, and reported that, due to gains in efficiency through well
maintenance and cleaning and equipment upgrades, the normalized average is no longer
representative of actual energy consumption and should be adjusted accordingly. Staff submitted
that current actual energy consumption (1,295,445 kWh) is more accurate than the nearly IO
year old normalized average. The current consumption produces about the same volume of
water using less power. Thus, Staff argued that current actual energy consumption levels be
used in this case and all future PPCA filings.
ORDER NO. 33565 2
Using the current actual energy consumption levels results in an annual power supply
cost of $92,608, rather than $103,972, as requested. This translates to a 2.8% PPCA rate, rather
than the 4.54% rate requested-or an overall decrease of approximately 1.4%. See Staff
Comments, Atch. A. Staff acknowledged that actual energy consumption could change in the
future, and committed to monitor and modify the consumption number if circumstances change.
2. Customer Relations Issues
Staff identified three customer relations issues that it believes should be addressed by
the Company going forward. Specifically, Staff found that: (1) the description of the PPCA in
Schedule No. 3 does not clearly explain what the charge is for or how it is calculated; (2)
customer billing statements do not accurately identify PPCA charges; and (3) the Company's
notice failed to state the proposed total dollar amount increase, and the percentage increase for
major customer classes, as required by Utility Customer Relations Rule 125.01, IDAPA
31.21.01.125.01.
Staff recommended the Company be directed to work with Staff to revise Schedule
No. 3 to reflect the purpose and calculation methodology of the PPCA. Staff further
recommended the Commission instruct the Company to revise its billing statements to better
identify the PPCA line item charge. Finally, Staff asked that the Commission require the
Company to review Rule 125, IDAPA 31.21.01.125, and to consult with Staff on future customer
notices to ensure compliance.
COMP ANY REPLY COMMENTS
The Company objected to Staffs recommendation to use a single year rather than the
2006-2008 three-year normalized average. The Company takes issue with the change in
methodology, and also argued that efficiency improvements come at a cost to the Company that
are not in rates. The Company claimed that it is currently working on, and soon intends to file, a
general rate case to update its overall rate structure. Because of this future rate case, the
Company proposed that rather than change the calculation methodology in this PPCA case, that
the Commission maintain the status quo here, and that the PPCA methodology be refined and
updated during the course of the forthcoming rate case.
With regard to the customer relations issues, the Company stated that it will work
with Staff on making the recommended changes going forward.
ORDER NO. 33565 3
DISCUSSION AND FINDINGS
The purpose of the PPCA mechanism is to allow the Company a way to adjust its
rates commensurate with changes it experiences when its power supply costs go up or down. See
Order No. 30881. The Company's power costs are determined by two factors: the amount of
power used, and the rate paid for the power. Here, there is no dispute that rates the Company is
charged for power have gone up. There is also no dispute that, through gains in efficiency, the
amount of power used by the Company has gone down. Accordingly, we find it appropriate to
use the Company's current, actual energy consumption as the basis of its PPCA as it produces a
more accurate forecast of what the Company will be paying for power over the next year.
We understand the Company's averseness to this change in the formula used to
forecast its power costs, as it results in an overall reduction in its Schedule 3 rates, but note that
we never intended the three-year normalized average to be permanent. Rather, in implementing
the PPCA mechanism, we held that "[f]uture changes in the Company s normalized kWh
consumption ... may necessitate changes to the present incremental power cost adjustments."
Id. We note further that on the face of the Company's Application, the requested increase by the
Company is barely inside the 0.25% revenue band required for a PPCA filing. See id. This is
especially concerning when we consider that nearly 60% of the increase is attributable to
expenses incurred in filing the Application.
After a thorough review of the record, we find the adjustment relating to the
Company's increased power rate appropriate, and that $1,100 in case preparation and filing costs
is reasonable. We find further that the Company's actual power consumption has decreased
from the three-year average used in base rates, and that 1,295,445 kWh of actual electricity
consumed over the past 12 months is a more accurate indicator of power use. Applying this
amount to the updated electricity rate of 7.15¢ per kWh results in an overall Schedule 3 decrease
from $27,699 to $18,225. We direct the Company to consider future changes in consumption
and rates going forward to ensure the purpose of the PPCA-to accurately match the Company's
power supply costs-is fulfilled.
Accordingly, we find that the Company shall decrease its PPCA by 1.45% from the
current 4.25%, and that the 2.8% PPCA should be reflected in the Company's Schedule 3.
