SUBJECT:CASE NO. IPC-06-
APPLICATION OF IDAHO POWER COMPANY TO REVISE ITS
IRRIGATION PEAK REWARDS PROGRAM
On September 18, 2006, Idaho Power Company filed an Application requesting
approval of changes to its Irrigation Peak Rewards Program, Schedule 23. The Irrigation Peak
Rewards Program is a voluntary load control program available to agricultural irrigation
customers who use pumps having a cumulative horsepower rating of 100 or greater. The
program is intended to decrease the Company s summer system peak by turning off specified
irrigation equipment between the hours 4:00 p.m. and 8:00 p.m. on one, two or three days per
week during the months of June, July and August. The Commission in Case No. IPC-05-
encouraged Idaho Power to conduct a workshop with interested parties to determine whether
revisions to the program would be appropriate. As a result of the workshop, Idaho Power filed
its Application to revise the program.
Idaho Power proposes to make two revisions to the program. First, the demand
credit for the two days per week and three days per week interruptions would be increased, as set
forth in the following schedule:
Interruption Option
Option 1 (1 day per week)
Option 2 (2 days per week)
Option 3 (3 days per week)
Current Demand Credit per kW
$2.
$2.
$2.
Proposed Demand Credit per k W
$2.
$3.
$4.
DECISION MEMORANDUM
The second revision is to reduce the horsepower limit to make the program available
to irrigators using pumps rated at 75 horsepower or higher. An installation fee of $250 would be
assessed for new program participants with irrigation pumps between 75 and 99 horsepower if it
is necessary to install a timer on the pumps.
Staff recommends that the Application of Idaho Power to revise its Irrigation Peak
Rewards Program, Schedule 23, be processed by Modified Procedure.
