CASE NO. IPC-E-14-29
IDAHO POWER COMPANY'S
RESPONSE TO THE THIRD
PRODUCTION REQUEST OF THE
COMMISSION STAFF TO IDAHO
POWER COMPANY
COMES NOW, ldaho Power Company ("ldaho Powed'), and in response to the
Third Production Request of the Commission Staff to ldaho Power Company dated
December 10,2014. herewith submits the following information:
IDAHO POWER COMPANY'S RESPONSE TO THE THIRD PRODUCTION
REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY. 1
REQUEST NO. 5: Please re-calculate the rates for the project by using in
AUROM the exact generation quantities and hourly and monthly shapes as are
represented in Appendix I of the Agreement. PIease compare the resulting rates to
those contained in Replacement Appendix E included as Attachment 1 to ldaho Power's
lnitial Comments. Please compare the 2O-year levelized rates under both scenarios
and calculate the difference in the total 20-year contractual obligation. With your
answer, please provide copies of all AURORA and Excel files used for the analysis.
RESPONSE TO REQUEST NO. 5: ldaho Power already uses the exact
generation quantities and hourly and monthly shapes as contained within Appendix I in
the incremental cost lntegrated Resource Plan ("lRP") model in the incremental pricing
too!. One input into the AURORA model that is required to establish the hourly
generation resource stack of existing resources (not including the proposed qualifying
facility ("QF') project) is the estimated hourly generation from all available resources
that exist prior to the addition of the proposed QF project. !n many cases, ldaho Power
does not have specific hourly energy estimates from the various QF projects; instead,
ldaho Power only has monthly energy estimates. Therefore, to create an hourly energy
shape of these QF resources, ldaho Power shapes the monthly energy estimates by
using generic information related to the resource types. ln the case of solar projects,
this hourly shaping has been based upon industry and local information with regards to
solar radiation and the expected energy deliveries from generic solar projects. Because
some solar projects are now providing hourly energy estimates, a potential
enhancement to the incremental cost IRP model will be to include the project specific
hourly energy estimates (when available) in the cumulative solar hourly energy shapes

that are used in establishing the hourly generation resource stack. ldaho Power has
included the applicable information for the revised incremental cost IRP model runs with
this response. A comparison of the 20-year levelized rates under both scenarios is
listed below.
