RE:SCHEDULE 72A - DISP TCHABLE IRRIGATION LOAD
CONTROL CREDIT RIDER; ROCKY MOUNTAIN POWER
TARIFF ADVICE NO. 08-01.
BACKGROUND
On January 7 , 2008, Rocky Mountain Power (Rocky Mountain; Company), a Division
ofPaciforp, submitted modifications to its Tariff LP.C. No., Schedule No. 72A, the
Dispatchable Irrigation Load Control Credit Rider. Specifically, the Company requested
revisions of Sheet Nos. 72A.1 , 72A.2, 72A.3 , and 72A.4. The purpose of the filing is to make
several adjustments to the tariff language and operational aspects of the dispatchable irrigation
load control program (Program). The proposed operational changes include a reduction in the
maximum dispatch hours, a small increase in the dispatch duration, and removal of the minimum
pump size and minimum aggregate demand. In addition, the Company is proposing that a
participant no longer needs to execute annual agreements with the Company. Rather, once
initiated, participation in the Program will continue until explicitly canceled by the customer.
The Company also indicated that the proposed changes are in addition to those recently
approved by the Commission in the Company s 2007 general rate case. See Order No. 30482.
These changes were discussed and agreed to by the Idaho Irrigation Pumpers Association (lIP
through negotiations leading to the rate case settlement. However, such changes were not
specifically addressed in the Stipulated Settlement. The proposals are the result of collaborative
discussions between the Company, lIP A and participating customers after successful operation
of the 2007 Dispatchable Pilot Program.
DECISION MEMORANDUM FEBRUARY 8, 2008
After initial review by Commission Staff and discussions with Rocky Mountain Power
the Company resubmitted a revised filing for the proposed changes to Schedule 72A on
February 7, 2008. The Company s filing is included as Attachment A to these comments.
ST AFF REVIEW
On February 13 2007 , the Commission issued Order No. 30243 approving the
Company s Irrigation Load Control Dispatched Pilot Program for the 2007 irrigation season.
The Program allows the Company to interrupt service to Idaho irrigation customers at the
Company s discretion. In return, participating customers receive a credit on their October billing
statement for the entire season. It was expected that the number of participants would be
selected, data would be collected, results would be assessed, and changes would be made in
order to make the Program more successful. The Commission also directed the Company to
prepare and file a report on the Dispatch Pilot Program after the close of the 2007 irrigation
season. The Pilot Program was in addition to the scheduled Irrigation Load Control Program
already in place. Based on the findings of the Pilot Program offered during the 2007 irrigation
season, the report recommended that the Pilot Program be made permanent with some
operational modifications.
Some of the key requirements of the Dispatchable Pilot Program that the Company seeks
to modify include: a total demand of at least 1 500 horsepower (Hp) under the customer s control
through single or multiple accounts, an integrated pump/pivot irrigation system, and a minimum
pump size of 100 Hp. In addition, total curtailment per participating customer will be limited to
65 hours during the irrigation season, with dispatched events occurring between the hours of
2:00 p.m. to 8:00 p., Monday through Friday.
After initial review by Staff, concerns were raised about the elimination of the 100 Hp
minimum pump size and the minimum total aggregate of 1 MW (1,500 Hp) demand under the
customer s control as Program requirements. Staff believes inclusion of all customers regardless
of pump size would not be prudent under this Program. There is a "cross-over point" where the
inclusion of smaller pumps will no longer be cost-effective. Staff notes that the Company
conducted an analysis of the cost of implementing the program for the first year as well as the
second year for three ranges of pump sizes and indicated that Program costs are higher during the
first year of participation due to the initial installation cost of control devices. While the analysis
DECISION MEMORANDUM FEBRUARY 8, 2008
shows that the cost of Program implementation is higher for smaller pumps in both the first and
second year ofthe Program, it does not clearly show at what point (e.g. pump motor size) the
program is no longer cost effective. The capital cost of the project was not amortized with the
Project's life.
There may be some cases where a customer would have several small pumps, but in
aggregate may be considered relatively large load or where a small pump load is part of a bigger
load. Staff believes that the smaller loads should not be excluded as long as they meet the
minimum total aggregate requirement.
After additional discussions with the Company, Rocky Mountain agreed to include a
requirement with a minimum irrigation motor load size of 30 Hp. The Company also proposed
that it would evaluate individual pumps or motors smaller that 30 Hp to determine if
participation is cost-effective or necessary because such pumps are part of a larger participating
system. Staff agrees with this change, which is now reflected in the revised filing submitted on
February 7 , 2008. Staff and the Company will work to reassess cost effectiveness at the
conclusion of the 2008 irrigation season.
Staff agrees with the proposed change that a participant no longer needs to execute
annual agreements with the Company. Once initiated, participation in the Program will continue
until explicitly cancelled by the customer. This change will reduce administrative work by the
Company for not requiring annual signup and will make Program management more efficient.
Staff also agrees with the other proposed operational changes of: a) reducing the
maximum dispatched hours from 65 to 52 hours per irrigation season, and b) increasing the
dispatch duration from not more than three and one half hours to four hours per dispatch event or
twelve hours per week.
RECOMMENDATIONS
1. Staff recommends that the Commission approve the requested revisions of Rocky
Mountain Power to Schedule 72A applicable to electric service in the State of Idaho.
2. If the Commission approves the proposed changes, Rocky Mountain Power suggests and
Staff recommends that the revised Tariff pages become effective on February 15 2008.

LOAD CONTROL SERVICE AGREEMENT: The Customer and Company will execute a LCSA
for irrigation load control participation. The LCSA shall specify the Load Control kW amount that each of
the Customer s sites shall curtail during each Dispatch Event. The agreement will also include typical costs
that the Customer may incur for Early Termination. Once executed, the agreement shall remain in force for
subsequent Irrigation Seasons unless explicitly canceled by the participating Customer. Cancellation of an
existing LCSA may occur only between September 16 and May 30 each year.
LOAD CONTROL SERVICE CREDIT: The LCSC for a participating site shall be calculated and
a check issued to the participating Customer no later than October 31 of each year. The LCSC is composed
of a Fixed Annual Participation Credit that shall remain fixed throughout the Irrigation Season each year.
The LCSC shall be computed at the conclusion of the Irrigation Season by multiplying the Fixed Annual
Participation Credit times the Load Control kW at the Schedule 10 metered pump site. The Load Control
kW shall be computed by taking the most recent 2-year demand (kW) average for that particular site.
The Fixed Annual Participation Credit for 2008 and 2009 is based upon total program participation volumes
as defined in the table below (Participation Credit Schedule).
