IPUC Data Request I
IPUC Data Request 1
Please provide justification for excluding the 90/l l0 requirements not included in
the proposed amended contact.
Response to IPUC Data Request 1
The existing power purchase agreement (PPA), dated June 27, 1985, did not have
conforming and non-conforming price differentiation. The proposed amendment
in the Company's application for a one-year extension to the existing PPA (from
April 30, ZOZL to April 30, 2022), seeks only to extend the existing PPA by one
year with updated prices. A longer term PPA, currently being negotiated and set
io begin at the end of the one-year extension period, will include the 90/110
requirements and other updated contractual terms.

IPUC Data Request 5
Page 3 of the Application states that, "the Seller and PacifiCorp are in the process
of securing a new stand-alone interconnection agreement that, after all
distribution system uperades are consfucted and in-service, will replace the
interconnection provisions in the current PURPA contract". Please answer the
following questions.
(a) Please speciff each of the distribution system upgrades and explain the
necessity of the upgrade.
(b) Please provide the date when the need for the distribution system upgrades
were first identified.
(c) Please provide a time schedule showing the major milestones for completing
the upgrades and when the upgrades are expected to be in-service?
Response to IPUC Data Request 5
(a) No distribution system upgrades were determined to be necessary. The only
requirement deemed necessary by PacifiCorp to allow the hydro facility to
remain interconnected to PacifiCorp's system was for the interconnection
customer to install protective relaying at its facility and input settings
provided by PacifiCorp.
(b) PacifiCorp produced a system impact study (SIS) on June 1,2020 which
identified all requirements necessary to allow the hydro facility to continue to
be interconnected to PacifiCorp's system.
(c) The milestone in the new interconnection agreement for the installation of the
new relay settings is January 15,2021. However, this has already been
completed. The hydro facility has already been granted commercial operation
under the new interconnection agreement.

Page 4 ofthe Application states that the total nameplate capacity of the facility
remains unchanged at 350 kilowatts (kW) and that the Facility's estimated net
output over the l-year extended term is 219 megawatt-hours. This equates to 25
average kW or aTYo arvrlual capacity factor. Please explain the low capacity factor
for this project when most small hydro facilities operate with a 30%oto 50%
annual capacity factor.
Response to IPUC Data Request 6
The 219 megawaff-hours (MWh) stated in the Application, page 4, was stated in
error. over the last three years, the facility's average annual output has been
approximately 1,900 Mwh per year, approximately equal to a 62percent capacity
factor (CF).

how it is determined. Will the capacity contribution change under the
Amendment? If so, please provide the new amount and explain how it is
determined. Please provide any work papers in Excel format with formula intact.
Response to IPUC Data Request 7
Please refer to Confidential Attachment IPUC 7.
To calculate the capacity confiibution at peak of the Nicholson Sunnybar Ranch
qualiffing facility (QF) power purchase agreement (PPA) used in PacifiCorp's
20lg Integrated Resource Plan (IRP), the monthly energy, stated in megawatt-
hours (MWh), was divided by the number of hours in the month to calculate the
average megawatt (aMW). It is the aMW thatwas used for the capacity
contribution at peak in PacifiCorp's 2019 IRP. The capacity contribution is not
expected to change under the Amendment.
