This Stipulation is entered into by and among Avista Corporation, doing business as
Avista Utilities ("Avista" or "Company"), the Staff of the Idaho Public Utilities Commission
("Staff), Clearwater Paper Corporation ("Clearwater"), Idaho Forest Group, LLC ("Idaho
Forest") and the Idaho Conservation League ("Conservation League")'. These entities are
collectively referred to as the "Parties," and represent several parties in the above-referenced
cases that participated in settlement discussions. The Parties understand this Stipulation is
subject to approval by the Idaho Public Utilities Commission ("IPUC" or the "Commission").
The Community Action Partnership Association of Idaho ("CAPAI") participated in settlement discussions and is
continuing to review its position with regard to the Settlement, as proposed, and will be filing separate comments
and/or testimony in that regard. The Snake River Alliance, as an intervenor, was provided notice of the settlement
discussions, but did not participate.

I. INTRODUCTION
1. The terms and conditions of this Stipulation are set forth herein. The Parties agree
that this Stipulation represents a fair, just and reasonable compromise of all the issues raised in
the proceeding and that this Stipulation and its acceptance by the Commission represents a
reasonable resolution of the multiple issues identified in these cases. The Parties, therefore,
recommend that the Commission, in accordance with RP 274, approve the Stipulation and all of
its terms and conditions without material change or condition.
II. BACKGROUND
2.On October 11, 2012, Avista filed an Application with the Commission for
authority to increase revenue from electric and natural gas service in Idaho by 4.6% and 7.2%,
respectively. If approved, the Company's revenues for electric base retail rates would have
increased by $11.4 million annually; Company revenues for natural gas service would have
increased by $4.6 million annually. The Company requested an effective date of April 1, 2013
for its proposed electric and natural gas rate increases. By Order No. 32689, dated December 4,
2012, the Commission suspended the proposed schedules of rates and charges for electric and
natural gas service.
3.Petitions to intervene in this proceeding were filed by Clearwater, Idaho Forest,
CAPAI, the Idaho Conservation League, and the Snake River Alliance. By various orders, the
Commission granted these interventions. See, IPUC Order Nos. 32678, 32680 and 32687.
4.Settlement conferences were noticed and held in the Commission offices on
January 17 and 24, 2013, and were attended by signatories to this Stipulation; further discussions
ensued. Based upon the settlement discussions among the Parties, as a compromise of positions
STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 2
in this case, and for other consideration as set forth below, the Parties agree to the following
terms:
III. TERMS OF THE STIPULATION AND SETTLEMENT
5. Overview of Settlement and Revenue Requirement. The Parties agree that Avista
should be allowed to implement revised tariff schedules designed to recover the following
revenue requirement in two steps, as summarized in Attachment A, and below:
Electric
Step 1: April 1, 2013
a. No electric base rate change effective April 1, 2013, instead of the proposed
4.6%, or $11.393 million.
Step 2: October 1, 2013
a.Overall electric base rate increase of 3.1% (3.2% in billed rates) or $7.825 million
effective October 1, 2013.
b.Offsets - Apply $3.865 million for rate mitigation purposes (the BPA Parallel
Operation Settlement 2), and amortize that offset over 15 months, from October 1,
2013 to December 31, 2014.
C. Net overall bill increase to customers of 1.9% effective October 1, 2013.

Change Ofiet Rate Change
April 1, 2013 0.0% 0.0% 0.0%
October 1, 2013 3.2% -1.3% 1.9%
2 The BPA Settlement Revenue of $3 .865 million represents the Idaho customers' share of $12.224 million (system)
for the past use of Avista's transmission system for the period January 2005 through February 2013. In December
2012, Avista and Bonneville reached a settlement that pertains to the use of Avista's transmission system by
Bonneville. Avista and Bonneville each own and operate transmission systems that are interconnected at various
points. Between June 1998 and December 2009, Bonneville integrated four generation projects onto its 115 kV
transmission system in the Walla Walla, Washington area. Bonneville sold transmission capacity to wind projects
totaling 336 MW. The transmission path for these four projects follows a single Bonneville line that has a rated
capacity of only 203 MW. Upon Avista's discovery of this situation, Avista asserted that Bonneville requires the
use of up to 133 MW of parallel capacity support through the Avista system in order to fulfill Bonneville's
transmission service obligations for these wind projects. The Settlement Agreement was intended to resolve the
issue of compensation to Avista for the prior use of its transmission system, as well as provide Bonneville with
continuing cost-effective parallel capacity support in lieu of constructing additional transmission facilities at this
point in time. Avista anticipates FERC approval of the Settlement in February 2013, after which Avista will bill
Bonneville.
STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 3
Natural Gas
Step 1: April 1, 2013
a. Overall natural gas base rate increase of 4.9% (5.0% in billed rates) or $3.115
million, instead of the proposed 7.2%, or $4.561 million, effective April 1, 2013.
Step 2: October 1, 2013
a.Overall natural gas base rate increase of 2.0% (2.0% in billed rates) or $1.330
million effective October 1, 2013.
b.Offsets - Apply $1.550 million PGA deferral credit balance from 2012 PGA 3 to
partially offset the base rate increase, amortized over 15 months, October 1, 2013
to December 31, 2014.
C. Net overall bill impact to customers of 0.3% effective October 1, 2013.

Billing Rate Net Billing

Change Oflet Rate Change
April !,20!3 5.0% 0.0% 5.0%
October 1, 2013 2.0% -1.7% 0.3%
6. Cost of Capital. The Settling Parties agree to a 9.8 percent return on equity, with
a 50.0 percent common equity ratio, and adopt the capital structure and resulting rate of return as
set forth below:
Capital ProForma ProForma
Component Structure Cost Weighted Cost
Total Debt 50.00% 6.01% 3.01%
Common Equity 50.00% 9.80% 4.90%
Total 100.00% 7.91%
In Docket AVU-G-12-05, the Commission approved Staffs proposal that approximately $1.55 million in Un-
refunded credit balances be held back due to the Company's filing of a "Notice of Intent to File a General Rate
Case." The Commission stated in Order 32651, on page 6, that "the resulting $1.55 million un-refunded credit
balance will help mitigate potential rate increases and provide rate stability for customers."

sharing (90% customer, 10% Company) until it is included in base rates as part of the
implementation of new rates from the Company's next general rate case anticipated in 2015.
10.Reardan Wind Site Deferral. The Parties agree to amortize the Reardan Wind
Project deferred balance of $1.747 million over a two-year period beginning April 1, 2013.
11.Amortization of 2013 Coyote Springs 2/Colstrip Maintenance Deferral. The
Parties agree that the amount deferred in 2013 related to the Company's O&M costs of its
Coyote Springs 2 (CS2) natural gas-fired generating plant and its fifteen (15) percent ownership
' In May 2008, Avista purchased the Reardan Wind Project Site from Energy Northwest, the then-current developer,
after it was demonstrated as the Company's least-cost option for securing a renewable resource for its customers,
consistent with its 2007 Integrated Resource Plan. Avista later chose to delay the construction of the Reardan
project and take advantage of much-lower costs for wind projects that emerged in 2011 (Palouse Wind). Avista
recorded $4.0 million of site acquisition and preparation costs, of which approximately $1.7 million is Idaho's share.
This includes approx. $0.37 million in AFUDC in accordance with Order No. 30611 (Case No. AVU-E-08-04)
STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 8

a.Cost of Capital. As previously described (see Paragraph 6 above).
b.Remove 2013 Capital Additions. Reflects total depreciation expense and rate
base, net of accumulated depreciation and accumulated deferred income tax,
Per Order No. 32371 in Case No. AVU-E-1 1-01, in order to address the large variability in year-to-year O&M
costs, beginning in 2011, the Company was allowed to defer changes in O&M costs related to its Coyote Springs 2
(CS2) natural gas-fired generating plant located near Boardman, Oregon, and its fifteen (15) percent ownership
share of the Coistrip 3 & 4 coal-fired generating plants located in southeastern Montana. The Company compares
actual, non-fuel, O&M expenses for the Coyote Springs 2 and Colstrip 3 & 4 plants with the amount of expenses
authorized for recovery in base rates in the applicable deferral year, and defers the difference from that currently
authorized. The deferral occurs annually, with no carrying charge, with deferred costs being amortized over a three-
year period, beginning in January of the year following the period costs are deferred.
STIPULATION AND SETTLEMENT —AVU-E-12-08 & AVU-G-12-07 Page 9
as of year-end December 31, 2012. Moves certain 2013 capital additions to
the October 1, 2013 rate change.6
c. Remove 2013 Expenses: Delay Recovery to October 1, 2013 Rate Change.
i.Information Services & Technology. Removes the 2013
incremental information service and technology expenses as
discussed above, to be included in the October 1, 2013 rate change.
ii.Non-Exec Labor. Removes the 2013 incremental non-executive
labor increases as discussed above, to be included in the October 1,
2013 rate change.
d. 2013 Property Tax. Removes the 2013 incremental property tax expense,
adjusting property tax expense to December 31, 2012 levels.
e. Remove Officer Incentive and CPI Escalation. Removes officer portion of
incentives and removes the Consumer Price Index adjustment on incentives
included in the Company's original filing.
f. Miscellaneous Adjustments. Includes a two-year amortization of Booz & Co.
consulting fees, thereby reducing test period expenses, and removes certain
other amounts related to injuries and damages, abandoned projects and
depreciation study expenses.
6 In the Company's filed case, inclusion of total net plant, including accumulated depreciation and accumulated
deferred income tax on an average-of-monthly-average basis for 2013, had the effect of reducing rate base by $1.309
million and increasing revenue requirement associated with a net increase in depreciation expense by $22,000. This
is due to the original filed adjustment that depreciated all plant, including the plant in service balance at December
31, 2012, to the AMA balance at December 31, 2013. The additional accumulated depreciation on plant in service
at December 31, 2012 was greater than the net plant additions in 2013 on an AMA basis, which had an overall
impact of reducing net rate base.

C. OTHER SETTLEMENT COMPONENTS
14.PCA Authorized Level of Expense. The new level of power supply expense, retail
load and Clearwater Paper generation, and the April 1, 2013 and October 1, 2013 Load Change
Adjustment Rates resulting from the April 1, 2013 and October 1, 2013 settlement revenue
requirements for purposes of the monthly PCA mechanism calculations, are detailed in
Attachment B. The parties agree for the purpose of Settlement in this case to accept the
Company's normalized load forecast without specifically accepting the weather normalization
methodology or the proposed Energy Efficiency Load Adjustment.
15.Depreciation Rates. The Parties have agreed to the updated electric and natural
gas depreciation rates as filed by the Company, with all common/allocated plant depreciation
rates, including the new depreciation rates for transportation equipment, effective January 1,
2013 to coincide with the Company's Washington and Oregon jurisdictions, with the remaining
direct Idaho plant depreciation rate changes effective April 1, 2013.
16.Earnings Test. The Company agrees to an after-the-fact earnings test, where it
would refund to customers one-half of any earnings in excess of the 9.8% ROE for each of the
years 2013 and 2014, to allay any concerns that the base rate relief in April 1, 2013 and October
1, 2013 may allow the Company to exceed its authorized return. The earnings test would be
based on actual, consolidated results for Idaho electric and natural gas operations.
17.Rate Freeze/Stay Out. The Parties agree that, in recognition of the two-year rate
plan covered by this Stipulation, Avista will not file another electric or natural gas general rate
case before May 31, 2014, and while it may request an effective date earlier than January 1,
2015, final approved new rates will not go into effect prior to January 1, 2015. This does not
apply to tariff filings authorized by or contemplated by the terms of the Power Cost Adjustment
(PCA), or the Purchased Gas Adjustment tariff (PGA), or other miscellaneous filings.
STIPULATION AND SETTLEMENT - AVU-E-12-08 & AVU-G-12-07 Page 12
D. COST OF SERVICE/RATE SPREAD/RATE DESIGN
18. Cost of Service. For electric operations, the Company prepared an analysis using
a peak credit method of classifying production costs, allocating 100% of transmission costs to
demand, and allocating transmission costs on a twelve-month basis. For settlement purposes, the
Parties agreed to use a pro-rata allocation based on the Company's proposed 15% move towards
unity for purposes of spreading the revised electric revenue requirement, while not agreeing on
any particular cost of service methodology.
For natural gas operations, the Company proposed that all rate schedules be moved
approximately 25% towards unity. For settlement purposes, the Parties agreed to use a pro-rata
allocation of the Company's natural gas rate spread percentages from its original filing for
purposes of spreading the revised revenue requirement.

19. Rate Spread/Rate Design (Base Rate Changes).
(a)As indicated above, the Parties agreed that the increase in base revenues
would be spread to all electric and natural gas rate schedules on a pro-rata allocation of
the Company's rate spread percentages from its original filing.
(b)The Parties agree that the revenue requirement for each electric and natural
gas service schedule will be applied as a uniform percentage increase to each volumetric
energy rate as shown in Attachment C. The Parties agree that there will be no change to
Schedule 1 and Schedule 101 basic charges.
(c)Attachment C provides a summary of the current and revised rates and
charges (as per the Settlement) for electric and natural gas service.

20. Rate Spread/Rate Design (Offsets).
STIPULATION AND SETTLEMENT - AVU-E-l2-08 & AVU-G-12-07 Page 13
(a)The Parties have agreed that the electric base rate offset related to the BPA
Settlement Revenues will be spread to electric rate schedules on a uniform cents per kWh
basis.
(b)The Parties have agreed that the natural gas base rate offset related to the
2012 PGA deferral credit balance of $1.55 million will be spread to natural gas rate
schedules on a uniform cents per therm basis.
(c)Attachment D contains the form of tariff related to the electric and natural gas
offsets agreed to by the Parties. A new electric rate schedule, Schedule 97, will be used
for purposes of passing through to customers the electric offset. A new natural gas rate
schedule, Schedule 197, will be used for purposes of passing through to customers the
natural gas offset. Both tariffs would expire on December 31, 2014.
(d)Any under- or over-refunded amounts relating to the Electric or Natural Gas
offsets will be trued up in the following year's Power Cost Adjustment (electric) or
Purchased Gas Cost Adjustment (natural gas).
