IDAHO POWER COMPANY'S
RESPONSE TO THE FIRST
PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO
POWER COMPANY
COMES NOW, Idaho Power Company ("Idaho Power" or "Company"), and in
response to the First Production Request of the Commission Staff to Idaho Power
Company dated December 20, 2011, herewith submits the following information:
IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION
REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 1
REQUEST NO.1: Please provide a narrative describing how the rates included
in Appendix F have been computed. Please provide a copy of all spreadsheets and
analysis used to derive the rates. If any component of the rates was developed using
AURORA, please provide a copy of all AURORA files used in the analysis (input,
output, data, etc.). Please provide all files in an electronic, executable format with
formulas intact.
RESPONSE TO REQUEST NO.1: The rates included in Appendix F are based
upon calculations from the Public Utilty Regulatory Policies Act of 1978 ("PURPA")
Integrated Resource Plan ("IRP") methodology and inputs at the time this agreement
was negotiated.
The IRP methodology is comprised of three components:
1. Avoided Cost of Energy;
2. Avoided Cost of Capacity; and
3. Integration Cost.
The above-listed components are described in greater detail below.
Avoided Cost of Energy
The Avoided Cost of Energy is a direct output from the AURORA dispatch modeL.
A confidential Excel workbook containing the input, output, and summary files that were
used to calculate the Avoided Cost of Energy for this project is provided on the
confidential CD. The confidential CD wil be provided to those parties that have
executed the Protective Agreement in this matter.
Following are the basic inputs and assumptions that were used in this model run:
. 2009 IRP base assumptions;
. 2009 IRP load forecast;
. 2009 IRP natural gas fuel cost forecast; and
. Estimated hourly energy shape provided by the project.

REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 2
Avoided Cost of Capacity
The Avoided Cost of Capacity is a calculation based upon the cost of a
combined-cycle combustion turbine ("CCCT") as identified in the 2009 IRP adjusted to
reflect the size and performance characteristics of this proposed project. The Excel file
provided on the confidential CD contains the files and formulas used to implement the
process described below to calculate the Avoided Cost of Capacity.
. The annualized capital (fixed) cost of a CCCT from the 2009 IRP is the
basis for the capital cost ($/kilowatt ("kW") month).
. This $/kW month value is converted to a total annual capital cost
based on the nameplate rating of the proposed project.
. The total annual capital cost is then multiplied by the project specific
peak-hour capacity factor. (A description of the peak-hour capacity
factor is provided below.)
. This result is then divided by the megawatt-hours ("MWh") of
generation from the proposed PURPA project, resulting in a $/MWh
rate for Avoided Cost of Capacity.
Peak-Hour Capacity Factor Calculation
. Project provided data
July, hours 3-7 p.m. average capacity factor 100%
. Benchmark resource - Idaho Power data
July, hours 3-7 p.m. average capacity factor 100%
July, hours 3-7 p.m. 90th percentile capacity factor 92%
. Calculation
100 percent divided by 100 percent equals a capacity multiplier
of 1.00
92.0 percent times the multiplier of 1.00 equals a peak-hour
capacity factor of 92.0 percent
IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION
REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 3
Sample Annual Calculation - Calendar Year 2014
Capital cost of a CCCT per the 2009 IRP = $14.17 per kW-month
($14.17 X (20 megawatts ("MW") X 1,000)) X 12 months = $3,400,800
annual capital cost
$3,400,800 X 92.0 percent peak-hour capacity factor = $3,128,736
$3,128,736 /109,500 MWh annual energy production = $28.58 per MWh
Integration Cost
No Integration Cost was applied to these price calculations due to the non-
intermittent operations of this project.
The response to this Request was prepared by Randy C. Allphin, Senior Energy
Contract Coordinator, Idaho Power Company, in consultation with Donovan E. Walker,
Lead Counsel, Idaho Power Company.

REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 4
REQUEST NO.2: Please explain the rationale for establishing a minimum Delay
Price as specified in §1.6. What is the basis for specifically choosing $15 per MWh as
the minimum Delay Price?
RESPONSE TO REQUEST NO.2: This project has provided a very specific and
exact 20 MW hourly energy shape for just heavy load hours; Idaho Power power supply
planning and system operations will include this specific energy shape and performance
in its planning and daily operation processes. If this project is delayed, there wil be
power supply planning impacts and potentially market transaction costs incurred. This
minimum $15 per MWh Delay Price was a negotiated value to compensate for potential
costs that may occur if the project is delayed.
The response to this Request was prepared by Randy C. Allphin, Senior Energy
Contract Coordinator, Idaho Power Company, in consultation with Donovan E. Walker,
Lead Counsel, Idaho Power Company.

REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 5
REQUEST NO.3: Please explain the rationale for a 15% reduction in applicable
energy prices if Net Energy deliveries exceed plus or minus 10% for the time periods
specified in §6.3 and §6.3.1.
RESPONSE TO REQUEST NO.3: This project is unique among most PURPA
projects in that it has committed to exactly 20 MW of energy deliveries just during heavy
load hours. The agreement contains a plus or minus 10 percent hourly performance
band that then triggers an adjustment to the contract price if the project fails to deliver
the promised energy. This price adjustment mitigates costs Idaho Power customers
may incur due to the project not performing as planned on an hourly basis. In addition,
paragraph 6.3 provides for additional payment reductions if the project fails to operate
within the performance requirements of this agreement for an extended period of time or
on a recurring basis.
As stated in the Company's response to Staff's Production Request No. 1 above,
a key input in developing the pricing for this and any other PURPA IRP-modeled pricing
is the project's anticipated energy shape as provided by the project. This energy shape
is then included in the IRP pricing modeL. If the project has overstated or understated
the actual energy shape of the project, the results of the IRP pricing may not be a
perfect match based on the actual generation versus the estimated generation used in
the IRP modeling. Various contract terms and conditions provide various levels of
pricing adjustments to compensate for this performance issue. Because this project has
provided exact energy amounts and time of day deliveries (20 MW all in all heavy load
hours), the potential price risk within this IRP model run is higher in comparison to
projects that are providing energy in all hours and at varying output levels. This
additional performance requirement was negotiated and inserted into this agreement to

provide another level of protection against Idaho Power's customers paying
inappropriate prices for energy production from this project.
The response to this Request was prepared by Randy C. Allphin, Senior Energy
Contract Coordinator, Idaho Power Company, in consultation with Donovan E. Walker,
Lead Counsel, Idaho Power Company.

REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 7
REQUEST NO.4: As specified in §6.4, please explain the rationale for
considering the Seller's failure to deliver 30,000 MWh in any Contract Year to be an
event of default. How was the 30,000 MWh amount chosen?
RESPONSE TO REQUEST NO.4: In all recent PURPA contracts, Idaho Power
has included a minimum performance level criterion at which an agreement may be
terminated in an effort to minimize termination disputes when a project has
catastrophically failed. A minimum annual energy delivery of 30,000 MWh was a
negotiated level of performance agreed to between the parties as a performance level
that would trigger termination of this agreement.
The response to this Request was prepared by Randy C. Allphin, Senior Energy
Contract Coordinator, Idaho Power Company, in consultation with Donovan E. Walker,
Lead Counsel, Idaho Power Company.
DATED at Boise, Idaho, this 10th day of January 2012.
