SECOND PRODUCTION REQUEST
TO IDAHO POWER COMPANY 1 AUGUST 3, 2011
In addition to the wrtten copies provided as response to the questions, please provide all
Excel and electronic fies on CD with formulas activated.
REQUEST NO. 12: Please explain why the capacity portion ofthe prices in the Firm Energy
Sales Agreement (FESA) were calculated based on a combined cycle combustion turbine (CCCT)
rather than a simple cycle combustion turbine (SCCT). Please re-calculate the rates in the FESA
using a SCCT for the capacity portion of the prices. Please provide a copy of all spreadsheets and
analysis used to re-calculate the rates.
REQUEST NO. 13: Please provide a copy of all spreadsheets and analysis used to compute
the capacity portion of the prices in the FE SA. Please cite the source of any CCCT or SCCT cost
data and clearly identify and explain any cost escalation factors used in the analysis.
REQUEST NO. 14: For each ofIdaho Power's gas-fired generation plants included in the
Aurora analysis performed to derive the rates in the FESA, please list by plant and by year the anual
capacity factor beginning in 2012 through the end of the analysis period.
REQUEST NO. 15: Wind integration charges were identified and quantified in Idaho
Power's 2007 wind integration study for penetration levels of 300 MW, 600 MW and 900 MW.
Recognizing that solar integration costs are likely to be different than wind integration costs, can
Idaho Power acknowledge that solar integration costs would not be zero for the Interconnect Solar
project? If Idaho Power acknowledges that solar integration charges are not zero, and recognizing
that the Company has not performed a solar integration study, can the Company conservatively
estimate a reasonable range of solar integration costs? If so, what is that range?
REQUEST NO. 16: The Aurora analysis performed to compute the energy value component
of the prices contained in the FESA generated hourly prices for all hours of the analysis period.
Using the hourly Aurora data, please "re-shape" the FESA prices by year, by season, and by flat,
light, heavy, and heavy load peak hours similar to the format used in the attached table. Please
provide a copy of the Aurora hourly data and any spreadsheets used to reshape the prices.
SECOND PRODUCTION REQUEST
TO IDAHO POWER COMPANY 2 AUGUST 3, 2011
REQUEST NO.1 7: Please provide a copy of the data and analysis used to derive the 90
percent exceedance value for hours ending 4:00 pm to 7:00 pm during July 2010 which, in turn, was
used to determine the 21 percent capacity factor assumed for the Interconnect Solar capacity value
analysis.
REQUEST NO. 18: Please provide summary tables, one for the Aurora analysis with the
Interconnect Solar project included and one without it, showing the kWhs generated by month and
year by each new and existing resource in Idaho Power's portfolio throughout the study period.
Please also include monthly off-system purchases and sales in the summar tables. The purpose of
the summar tables is to determine which resources in the portfolio would be displaced or deferred by
the addition of the Interconnect Solar project.
Dated at Boise, Idaho, this 3/Ù day of August 2011.
