REQUEST:
The original 1986 contract at 13 states that the Facility has a 900-kilowatt nominal rating.
However, Exhibit D of the Power Purchase Agreement ("PPA") states that the nominal rating is
1,010 kilowatts. Please answer the following questions.
a. Please explain what 'nominal rating" means and how this rating differs from the nameplate
rating.b. Please explain why the nominal rating in the original 1986 contract differs from the
nominal rating in the PPA.c. What was the installed nominal rating when the Facility was first constructed?d. Has the nominal rating changed since construction? Please explain.e. Please provide evidence for the current, actual nominal rating.
RESPONSE:
a. Nominal rating is the theoretical output (capacity) of the generator. While nameplate
rating is not used in this agreement, it has the same meaning as nominal rating.
b. It appears the term nominal capacity in the 1986 contract included the effect of the
limitations of the penstock. The new contract includes additional detail to clarify the
nominal rating of the generator, absent any penstock limitations, is 1,010 kW and the
maximum net power production capacity under ideal conditions, glven the penstock
limitations, is 900 kW.c. It appears it could have been more clearly stated as 1,010 kW.
d. No, the nominal rating has not changed, nor has the maximum net power production
capacity, however, the 1986 contract did not include the additional detail regarding the
effect of the penstock limitations.e. The Project Developerprovided the description of the facility in Exhibit D.

REQUEST:
Exhibit D of the PPA also states that the maximum net power production capacity under
ideal conditions is approximately 900 kilowatts. Please answer the following questions .
a. Please explain how the " maximum net power production capacity under ideal
condition s" is determined .
b. What was the "maximum net power production capacity under ideal conditions"
under the original 1986 contract?
c. If the value was not 900 kilowatts, please explain what has caused the value to
change?
RESPONSE:
a. The Project Developer estimated the ma:rimum net power production capacity based
on the limitations of the diameter of the penstock which reduced the project's ability
to achieve the nominal rating.
b. Please see the Company's response to Production Request No I The maximum net
power production capacity under ideal 900 kW.
c. N/A.

REQT]EST:
The PPA defines Operating Year as "each l2-month period from July 1 through June 30." The
original 1986 contract expires on October 30,2022. Please explain whether Operating Year
should have been defined as "each 12-month period from October 31 through October 30".
RESPONSE:
The Operating Year should be defined as "each l2-month period from October 31 through October
30". Avista intends to submit an amendment to correct the definition of "Operating Year".

REQUEST:
Please list all the identified capacity deficiency periods that required the Company to add
resources since 1986 and provide the capacity resources that were actually added and the dates
when they went online.
RESPONSE:
The information requested dating back to 1986 is not readily available and would be time
consuming to find and compile. Regarding capacity, the 1986 contract included "...payments to
the Seller by Water Power each month for electric energy and capacity..." Therefore, as noted in
the Joint Petition of Avista Corporation and Idatro County Light and Power Cooperative ("Joint
Petition") filed in this proceeding: "Under the prior power purchase agreement, Avista purchased
the capacity and e,nerry from the Facility. Accordingly, pursuant to Commission precedent, the
Facility is eligible for both the avoided cost of energy and capacity in this Agreement. See Order
No. 32697." Joint Petition at3 n.2.
