REQUEST:
In his testimony on page 21, lines 2I-22 and page 22,lines 1-2, Company Witness Thackston
states: "As the costs and technology of clean energy and energy storage continue to improve, and
as other markets develop, we anticipate there will be a time when we no longer need Colstrip, and
we continue to work with our five co-owners related to the future of the plant."
a. Please provide all studies, analysis, communications, memos, or other materials that support
the Company's anticipation of when Colstrip will no longer be needed.
b. When the Company determines it no longer has a need for Colstrip, must the Company secure
approval from the other co-owners of Colstrip Units 3 and4 to retire and shutdown Units 3 and
4, or otherwise terminate the Company's ownership stake in Units 3 and 4? In answering this
request, please cite to and provide the relevant Colstrip contract provisions that support the
Company's answer.
RESPONSE:
Please see Avista's response ICL_PR_002C, which contains TRADE SECRET,
PROPRIETARY or CONFIDENTIAL information and exempt from public view and is
separately filed under IDAPA 31.01.01, Rule 067 and233,and Section 9-340D,Idaho Code.
a) This is a forward looking statement that indicates further improvements in costs, technology,
and markets are necessary in order for that anticipation to come to fruition. As such, there are no
responsive materials.
b) The ownership and operation agreement provides the terms under which Colstrip Units 3 & 4
are operated and maintained. Section 3l of that agreement speaks to circumstances where "the
Project can no longer be made capable of producing electricity consistent with Prudent Utility
Practice or the requirements of governmental agencies having jurisdiction. . . ." The ownership
and operation agreement, including Section 3l of that agreement, speaks for itself. Please see

In his testimony on page 21, lines 18-21, Company Witness Thackston states: "Colstrip has been
an important source of generation in the region and for Avista's customers for over 30 years. It is

enough water flowing down our rivers to generate enough electricity to meet our customers '
energy needs. "
a. Please provide any dates Colstrip Units 3 and 4 were shut down during 2018. For each
instance, please indicate whether the shutdown was planned our unplanned. If unplanned,
please describe the cause and the process by which the unplanned shutdown was resolved.

4 ultimately resumed providing electricity to Idaho electric customers?
b. Please provide the I -hour and lS-hour sustained peak energy demands on Avista's system,
in megawatts, for any time periods when Units 3 and 4 were shut down in20l8, and please
provide the percentage of these energy demands that Units 3 and 4 would have been
expected to meet had they not been shut down.
c. Please provide a detailed explanation of how Avista generated and provided sufficient
electricity to meet customer needs during each unplanned outage at Colstrip Units 3 and 4
during 2018.d. Colstrip shutdown during the summer of 2018 to address pollution controls administered
by the Montana Department of Environmental Quality. Please provide a detailed breakout
by category of the costs associated with the shutdown of Units 3 and 4 in the summer of

RESPONSE:
Please see Avista's response ICL_PR_003C, which contains TRADE SECRET,
PROPRIETARY or CONFIDENTIAL information and exernpt from public view and is
separately filed under IDAPA 31.01.01, Rule 067 and233, and Section 9-340D,Idaho Code.
a.Please see "ICL_PR_O03C Confidential Attachment A Colstrip Hourly Generation". This
document provides the hourly generation for unit 3 and unit 4 for 2018.
Please see "ICL_PR_OO3C Confidential Attachment B for 2018 U34 Plant Summary
Reports.pdf'. This document lists the outages and their causes via the various GADS
(Generation Availability Data System) categories (i.e. planned/unplanned). Talen as
operator of the facility seeks to resolve each issue as quickly as possible, generally with
onsite staff but supplernented with external resources as necessary.
The alleged MATS violation period extended from June 2l'1,2018 to September 6ft, 2018.
Although there was outage time associated with the MATS issue, the units provided
electricity to Idaho electric customers during these periods when the units were run for
troubleshooting and testing to resolve the MATS issue.
b. Please see the ICL_PR_O03C Confidential Attachment C (Colstrip Outage Replacement
Cost) for the analysis of the cost of replacement power for the Colstrip outages and
de-rates. Also shown in that worksheet is the system load for each hour of Colstrip outage
or de-rate and the megawatt reduction in generation from the outage or de-rate.
c. On the margin, the unplanned outages at Colstrip resulted in either increased power
purchases or reduced power sales. Avista's other generation plants dispatch independently
of what Colstrip is generatinE, i.e, they dispatch against the market and not to load. The
attached analysis of Colstrip replacement power cost assumes that the alternative to
Colstrip generation is market power. See ICL_PR_003C Confidential Attachment D -
CL3C.
d. See part (b) and (g).
e. To date, MDEQ has not issued any penalties for the 2018 calendar year. An on-going
discussion concerning the alleged violation for 77 days of deviation from the PM emission
limitation has not concluded.
f. Avista cannot estimate penalty amounts at this time.
g. Please see ICL_PR_003C Confidential Attachment E for 2018 O&M and Capital
Expenditures for 2018. The information contained in this attachment is Avista's 1502
portion of the total 2018 Expenses incurred by Colstrip. This information is provided in
the method received by the Plant Operator and recorded to the general ledger. Any
expenses related to the Colstrip MATS issue are embedded within these numbers. The
capital costs reflected on the attachment represent total costs related to Colstrip and are not
specific to the outage and de-rate. The Company does not track this information on an
individual project basis. The amount included on the attachment represents what was
recorded to the general ledger, and transferred to plant in the month recorded.

REQUEST:
In his testimony on page 17, lines 16-21, Company Witness Thackston states: " ... the current coal
supply contract for Units 3 and 4 expires at the end of 2019. The Company has been involved in
negotiations to extend this contract, but Westmoreland Coal, the owner and operator of the
Rosebud Mine that supplies Colstrip, filed for Chapter I I bankruptcy in October 2018. A group of
creditors purchased the Rosebud Mine assets, and that goup accepted the current contract and will
honor it for the rest of 2019. Negotiations with the creditors for a new contract are ongoing.
a. Is Avista requesting revenue for coal supply as part of base rates in this docket? If so,
please identify the amount and provide documentation justifuing this amount
b. Please explain what a "cost-plus" agreement means, as Avista used this term in reference to
the Coal Supply Agreement that govems the cost of fuel for Colstrip Units 3 and 4 in
AVU-E-I9-04 Certificate of Service 3 September 11, 2019 Objection by Puget Sound
Energy, Inc., Portland General Electric Company, Pacificorp, and A vista Corporation to
Joint Chapter 11 Plan of Westmoreland Coal Company and Certain of its Debtor Affiliates
at 11, In re: Westmoreland Coal Company, et. Al.,Debtors, (Bankr. S.D. Tex. 2019) (No.
18-35672 (DRJ)) ("In short, the Rejection Notice's failure to include the Coal Supply
Agreement as a contract that will be assigned to the Purchaser is not credible because there
is no justification for rejecting it, and strikes the Public Utilities as nothing more than a
litigation tactic to drive Public Utilities to accept unreasonable commercial terms on the
new contract that is supposed to take effect in2020. This is especially true given the Coal
Supply Agreement is a'cost-plus'agreement, and is per se profitable for WECO.").
c. Is Colstrip able to burn coal from a source other than Rosebud mine according to current air
quality permits? Is the Colstrip facility able to receive coal by rail car or truck?
RESPONSE:
a. Coal supply costs are included in the overall power supply expense in this general rate
case. Please see Kalich workpapers, Ehibit No. 7 - Schedules 3 and 5.
b. "Cost-plus" refers to the payment structure of the 2nd Amended and Restated Coal Supply
Agreement between the owners of Colstrip and Westmorland Rosebud Mining LLC. The
price charged for coal includes all of the cost the mine incurs to mine coal plus a return on
invested capital, an incentive fee, and federal and state taxes and royalties.
Page 1 of2
c. The air permit allows for coal to be burned from a source other than the Rosebud mine.
However, the Colstrip facility is not currently configured to receive coal by rail, car, or
truck.

be eliminated in Idaho?
b. [f energy from Colstrip continues to be provided to Idaho electric customers after 2025,
will Idaho electric customers be solely responsible for A vista's portion of costs
associated with Colstrip, such as ongoing capital projects, the coal supply from the
Rosebud Mine and ongoing pollution issues covering both air quality and water quality
regulations?
RESPONSE:
a. This is yet to be determined.

should also be remembered that the compensation structure for the plant operator is cost-based
and does not include a rate of return based on the capital spending at the plant ... so there is no
financial incentivefor them to spend needless capital."
a. Does the Company's rate of retum on capital investments create a financial incentive to spend
capital?
RESPONSE:
No, the rate of return on capital investment is not an incentive, but rather reflects the cost of capital
necessary to attract funding on a reasonable basis so that we can continue to provide safe and
reliable service for our customers. Avista has, and will continue to operate the business efficiently
to keep costs as low as practicable for our customers, while at the same time ensuring that our
energy service is reliable and our customers are satisfied. An efficient, well-run business is not
only important to our customers, but also important to investors. We are making significant
capital investments in our electric generation, transmission and distribution facilities, natural gas
distribution system, and new technology to better serve the needs of our customers. These
investments are focused on, among other things, the preservation and enhancement of safety,
service reliability and the replacement of aging infrastructure.
