COMES NOW, ldaho Power Company ("ldaho Power" or "Comp?fly"), and in
response to the ldaho lrrigation Pumpers Association, lnc.'s ("llPA") Second Data
Requests to Idaho Power Company dated January 19,2017, herewith submits the
following information :
IDAHO POWER COMPANY'S RESPONSES TO THE IDAHO
IRRIGATION PUMPERS ASSOCIATION, INC.'S SECOND DATA REQUESTS - 1
REQUEST NO. 16: ln Attachments 2 and 3 to the Company's response to llPA
request #8 there was listed monthly summaries for the energy and cost of production
from various sources. With respect to July 2034, many of the sources produced the
same energy under Attachment 2 (without Valmy) and under Attachment 3 (with Valmy).
Most sources that produced different energy levels were in effect producing more to
make up for what Valmy produced under Attachment 3. However:
a. The lRP Resources under Attachment 2 (no Valmy) produced
approximately 80o/o less than when Valmy was operated. Please explain this
unexpected result.
b. The DSM resource under Attachment 2 (no Valmy) produced slightly less
than when Valmy was operated. Please explain this unexpected result.
RESPONSE TO REQUEST NO. 16:
a. Attachments 2 and 3 to the Company's response to llPA's Request No. 8
are the summary Aurora output files for model runs without Valmy after 2025 and with
Valmy, respectively. The reason the lntegrated Resource Plan ("lRP") Resource in
Attachment 2 (without Valmy) produced approximately 80 percent less than in
Attachment 3 (with Valmy) is a result of the differences in the total generation resource
mix available to the Aurora model for each run and the manner in which the resources
were economically dispatched. Aurora uses the costs, constraints, and rules for
operation of each available resource, and determines the most cost-effective economic
dispatch to serve load. The differences in the output of the various resources in
megawatt-hours ("MWh') of the Aurora runs in Attachment 2 (without Valmy) and
Attachment 3 (with Valmy) are reflected in the table below. As shown in the table, the
elimination in July of 85,475 MWh from Valmy was largely made up with an increase in
the generation at Langley Gulch, an increase in Market Purchases, and a decrease in
IDAHO POWER COMPANY'S RESPONSES TO THE IDAHO
IRRIGATION PUMPERS ASSOCIATION, INC.'S SECOND DATA REQUESTS - 2
Market Sales, with Danskin running just a couple of hours to meet peak !oad. The
reduction in the generation of the IRP Resource, which was dispatched in Attachment 3
(with Valmy), is a result of that resource only being needed for one day at the end of the
month, heading into the month of August. The number of total generation MWh is the
same in both model runs.

b. As shown in the table above, the demand-side management ("DSM")
resource for the Aurora run in Attachment 2 (without Valmy) produced slightly fewer
MWh than it did for the run in Attachment 3 (with Valmy). Again, the difference is due to
the generation resource mix used to meet load in each of the Aurora model runs. The
8.3 MWh is an existing DSM peaking resource (one of the demand response programs
the Company currently has in its portfolio), which was not needed to meet the peak load
for the one hour it was originally dispatched. That load was being met with the
resources economically dispatched at the time.
The response to this Request is sponsored by Tom Harvey, Planning Resource
and Operations Director, ldaho Power Company.
IDAHO POWER COMPANY'S RESPONSES TO THE IDAHO
IRRIGATION PUMPERS ASSOCIATION, INC.'S SECOND DATA REQUESTS - 3
REQUEST NO. 17: ln Attachments 2 and 3 to the Com pany's response to !lPA
request #8 there was listed monthly summaries for the energy and cost of production
from various sources. lf the Company has this data on an hourly basis, please provide
it in electronic format for both Attachment 2 and 3 for the years 2030 through 2434.
RESPONSE TO REQUEST NO. 17: ldaho Power does not retain hourly data for
the IRP analysis; therefore, hourly data does not exist for the years 2030 through 2034.
The response to this Request is sponsored by Tom Harvey, Planning Resource
and Operations Director, ldaho Power Company.
IDAHO POWER COMPANY'S RESPONSES TO THE IDAHO
IRRIGATION PUMPERS ASSOCIATION, INC.'S SECOND DATA REQUESTS - 4
REQUEST NO. 18: ln the Companies response to llPA request 12, it was stated
that: "The 2016 analysis was performed to further analyze the implication and
circumstances of a Valmy shutdown." Please answer the following:
a. What "further analyze" was performed?
b. What "implications and circumstances" were discovered and/or addressed
in the 2016 analysis that were not addressed in the 2015 IRP?
RESPONSE TO REQUEST NO. 18:
a. The 2016 analysis evaluated the impact on the total portfolio cost with the
associated forecasted fixed and capital costs of alternative Valmy shutdown dates
without generation or transmission additions.
b. The area of interest not included in the 2015 IRP was modeling related to
relying on import capacity from Northern Nevada via the existing Valmy transmission
line. The 2016 analysis informs the 2017 IRP development to further evaluate the
Valmy transmission path as a reliable, cost-effective resource to serve load.
The response to this Request is sponsored by Tom Harvey, Planning Resource
and Operations Director, ldaho Power Company.
