IPUC Data Request I
IPUC Data Request 1
Page 6 of the Power Purchase Agreement (PPA) in Case No. PAC-E-21-10 states
that the Nameplate Capacity Rating of the facility is 0.45 MW. Page I of the
Application in Case No. PAC-E-20-17 states that the nameplate capacity rating of
the same facility is 350 kW. Please reconcile the difference providing the cause of
the difference in nameplate capacity between the two cases.
Response to IPUC Data Request I
The Nameplate Capacity Rating of 0.45 megawatts (MW), as stated on page 6 of
the power purchase agreement (PPA) in this proceeding was verified from a
facility nameplate image that the facility owner recently sent to the Company at
the Company's request. TheNameplate Capacity Rating of 350 kilowatts GSD,
as stated on page 1 of the Application in Case PAC-E-20-17, was an oversight on
the Company's part, especially given that the nameplate image provided to the
Company by the facility owner states "Rated KW 450". Note: the original PPA
between Nicholson's Sunny Bar Ranch and Utah Power and Light Company
(UP&L) was executed in June 1985. That original PPA stated that the Nicholson's
Sunny Bar Ranch hydroelectric facility had a capacity of 350 kW. PacifiCorp has
no documentation to verifr or explain why the original 1985 PPA stated 350 kW.
Please refer to Attachment IPUC 1 which provides a copy of nameplate image
referenced above, verifuing 450 kW.

IPUC Data Request 2
If the change in nameplate capacity is due to modifications of the facility or
equipment, please provide the following:
(a) What modifications has the Seller made to the facility to increase its
Nameplate Capacity Rating from 350 kW to 450 kW?
(b) When were the modifications made?
(c) Please describe the configuration of the 350 kW facility and the configuration
of the 450 kW facility after the modification.
(d) If there were multiple generators in the 350 kW facility, please describe how
the generators operated under different situations regarding water availability
(e) If there are multiple generators in the 450 kW facility, please describe how the
generators operate under different situations regarding water availability.
(0 Did the 350 kW facility have a meter for each generator?
(g) Does the 450 kW facility have a meter for each generator?
(h) Does the facility have a separate meter that measures the output from the
added capacity?
(i) What level of generation data (frequency, time resolution, etc.) can the
Company collect from the meter(s) installed at the facility?
O Please provide the amount of generation in each hour from the facility for the
past five years (from 2016 to 2020).
Response to IPUC Data Request 2
(a) No modifications have been made in the history of the generator and turbine
equipment since the original equipment installation over 35 years ago. In the
last three years, the facility owner has performed maintenance on the water
line that feeds the generator as the original concrete water line had
deteriorated and was leaking extensively. Requirements of the transmission
interconnection agreement to install safety relays were also completed near
year end 2020. Neither the water line maintenance nor the installation of
transmission interconnection safety relays changes the original nameplate
capacrty of a generator unit as nothing in the generator unit itself has been
modified.

(h) No. Please refer to the Company's response to subpart (f) above.
(i) A meter change out occurred in March 2021 and the new meter is capable of

O Until the new meter was installed (March 2021), hourly meter reads were not
available. Please refer to the table below which reflects the energy output, in
kilowatt-hours (kWh), by month from 2016 through 2020 which were
manually recorded and settled from the old meter (that has since been
replaced):
