Form S-4

General

      1.    We note that AVA Formation Corp. is a newly formed company and does
            not meet the requirements for the use of Form S-3. Please
            substantially revise to include the information required by Item 14
            of Form S-4 with respect to AVA Formation Corp.

                  AVA is a new subsidiary of Avista, formed solely for the
            purpose of effecting the reorganization into a holding company
            structure. AVA has no assets (other than a nominal amount of
            capital), no liabilities, no operations and no revenues or expenses.
            For purposes of clarification, this disclosure has been added to the
            Proxy Statement-Prospectus on pages 3 and 30. There is no more
            information of any kind regarding AVA.

      2.    Please provide us with any gatefold information such as pictures,
            graphics or artwork that will be used in the prospectus.

                  There is no gatefold information, whether pictures, graphics
            or artwork, that will be used in the Proxy Statement-Prospectus,
            except the organizational charts that appeared on pages 32-34 in the
            Registration Statement. These charts have now been removed, but new
            improved charts have been inserted into the Summary in Amendment No.
            1 in response to comment 11.

Form of Proxy

      3.    We note that the form of proxy includes a statement that the proxy
            confers the power to vote shares on the proposal and "such other
            matters as may properly come before the meeting or any adjournments
            thereof." Provide an opportunity to specify by boxes a choice
            between approval or disapproval. Refer to Rule 14a-4(b).

                  Reference is made to comment 16 and our response thereto
            regarding adjournments. The following discussion is qualified by
            such response and is directed at other matters which may come before
            the meeting or adjournments thereof -- that is, matters other than
            the question of whether or not the meeting should be adjourned. We
            believe that our response to comment 16, together with the
            additional language inserted in the Proxy Statement-Prospectus under
            "VOTING PROCEDURES", adequately addresses that question.

                  We respectively disagree with the proposition that Rule
            14a-4(b) requires that a form of proxy provide an opportunity to
            specify by boxes ("Choice Boxes") a choice between approval or
            disapproval of, or abstention with respect to, the authority of the
            proxies to properly vote in their discretion upon other matters
            which may be brought before the meeting and of which the registrant
            has not received



Securities and Exchange Commission
Mr. H. Christopher Owings
March 23, 2006
Page 3

            timely notice, as provided in Rule 14a-4(c), and, indeed, has
            received no notice at all. A requirement for such Choice Boxes would
            appear to be effectively changing the Rule to say that discretionary
            authority is never granted, as to any matter, unless the shareholder
            has specifically granted it.

                  Rule 14a-4(a) provides that the form of proxy shall, among
            other things, identify each separate matter intended to be acted
            upon; provided, however, that no reference need be made to proposals
            as to which discretionary authority is conferred pursuant to Rule
            14a-4(c), even if the registrant has received timely notice as
            contemplated in Rule 14a-4(c)(2). Obviously, no such identification
            is required or, indeed, can be made in the form of proxy as to
            matters of which the registrant has not been notified.

                  Rule 14a-4(b) requires Choice Boxes for each separate matter
            referred to in the form of proxy as intended to be acted upon.
            Paragraph (b)continues to permit a form of proxy to confer
            discretionary authority with respect to matters as to which a choice
            is not specified in the Choice Boxes, provided that the form of
            proxy indicates how the proxies intend to vote as to such matter.
            Nowhere in paragraphs (a) and (b) is any requirement to let a
            shareholder specify whether or not discretionary authority is
            granted as to any matter (whether or not such matter is identified
            in the form of proxy).

                  Rule 14a-4(c) specifically permits a form of proxy to confer
            discretionary authority, in the case of an annual meeting of
            shareholders, as to seven categories of matters that may come up at
            the meeting including, particularly:

                  1.    matters as to which the registrant did not receive
                        timely notice, provided that a specific statement to
                        the effect that discretionary authority is granted is
                        contained in the proxy statement or form of proxy; and

                  2.    even matters as to which if the registrant did receive
                        timely notice, provided that the registrant also
                        includes in the proxy statement advice on the nature of
                        the matter and how the proxies intend to vote on the
                        matter (subject to certain exceptions relating to
                        counter-solicitations).

            Nowhere does Rule 14a-4(c) suggest that a form of proxy may confer
            such discretionary authority only if the shareholder indicates on
            the form of proxy that the shareholder elects to confer such
            authority.

                  It is our position that when Rule 14a-4(a) states that "a
            proxy may confer discretionary authority...", the Rule is not
            granting permission to the shareholder to grant discretionary
            authority because it would seem that the shareholder has the right
            and the power to grant whatever authority he or she wants, by
            signing a proxy card or a general or limited power-of-attorney.
            Rather, the Rule is granting permission to the person soliciting the
            proxy (in this case the issuer) to draft the proxy card so as to
            require the shareholder to grant discretionary authority as to
            certain matters by merely signing the card.

                  We respectfully request an opportunity to meet with the Staff
            to discuss this issue in advance of an adverse determination.

      4.    Please revise Proposal 2 to refer to the share exchange in
            connection with the reorganization to a holding company structure.

                  The form of proxy has been revised to refer to the share
            exchange.

Front Cover of the Proxy Statement/ Prospectus

      5.    Please revise the cover page as follows:

            -     Please limit the front cover to one page;

            -     Please omit the use of defined terms on the cover and in the
                  prospectus; instead, use abbreviated terms or terms that are
                  clear from their context;

            -     Please disclose recent stock price information for Avista
                  common stock and the trading symbols for Avista and AVA;

            -     Please highlight the risk factor reference by separating it
                  from the rest of the paragraph that appears in bold, or in
                  some other manner; please remove the other cross-references to
                  "Proposal Two" since this is not information required by Item
                  501 of Regulation S-K;

            -     Please disclose the total number of shares being offered in
                  the share exchange;

            -     Please identify the person making the proxy solicitation;
                  refer to Item 4 of Schedule 14; and

            -     Please revise to clarify that Avista's common stock will be
                  delisted after the share exchange is consummated.

                  The cover page of the Proxy Statement-Prospectus has been
            revised in accordance with these comments; provided, however, that
            AVA does not yet have a NYSE trading symbol (although "AVA",
            Avista's current symbol, has been reserved). We believe that, since
            "AVA Formation Corp." is only a temporary name for the holding
            company and the permanent name has not yet been determined, it would
            not be practicable at this time to determine and disclose a trading
            symbol for AVA.

                  We note that this page already contains, at the bottom, a
            statement as to on whose behalf the solicitation is made.

                  The cover page will be all on one page when it is printed and
            the "red herring" legend has been removed.

      6.    Please move this section so that it appears after the risk factors.

                 This section has been moved to follow "RISK FACTORS".

Incorporation of Documents by Reference, page 1

      7.    We note that you filed on March 7, 2006 your Form 10-K for the
            fiscal year ended December 31, 2005. Please revise your disclosure
            to refer to this most recent Form 10-K. See Item 11(a) of Form S-4.

                  Since Avista's 2005 Form 10-K has been filed, this section has
            been revised to refer to the 2005 Form 10-K.

Summary, page 3

      8.    Please revise to include the information required by Item 5 of
            Schedule 14A.

                  None of the individuals specified in Item 5(a) of Schedule 14A
            has any interest in Proposal 2 or Proposal 3 which is required to be
            disclosed. Reference is made to the instruction to Item 5(a).

      9.    Please briefly describe the material differences in the rights of
            stockholders of Avista and AVA Formation. For instance, it appears
            that there are differences with respect to cumulative voting to
            elect directors, the percentage required to approve amendments to
            the charter will be lowered from 80% to two-thirds, and the
            preferred purchase right will be eliminated.

                  Material differences between the rights of Avista and AVA
            shareholders have been briefly described. Please note that in the
            State of Washington shareholders have cumulative voting rights
            unless denied by the articles. See RCW 23B.02.020(3)(v), 23B.07.280.
            AVA's articles do not deny cumulative voting rights.

      10.   Please briefly describe the revocability of the proxy.

                  The revocability of proxies has been noted in the introduction
            to the Summary on page 3, in addition to the existing disclosure in
            "VOTING PROCEDURES".

      11.   For ease of understanding, please include in your summary
            organizational charts comparing your current structure and the
            holding company structure. Refer to the Avista Form 425 filed on
            March 3, 2006.

                  New and improved organizational charts have been inserted into
            the Summary and the charts later in the document have been removed.

Selected Avista Financial Information, page 5

      12.   Please consider the use of the word "unaudited" for the year ended
            December 31, 2005. While this information appears to be derived from
            the audited financial statements of Avista for the relevant years,
            none of it is covered by an audit report and the use of the word
            unaudited to describe a part of the information may imply that the
            information presented for the preceding years are audited.

                  The word "unaudited" has been centered to indicate that it
            applies to all three columns.

Risk Factors, page 7

      13.   Your introductory paragraph implies that you are incorporating risk
            factors by reference. Please note that all material risk factors
            must be disclosed in the proxy statement/ prospectus. Please revise
            the introductory paragraph of this section to eliminate the
            implication that you have not discussed all material risks, and
            revise as necessary to include a discussion of all material risks in
            your Risk Factors section.

                  The risk factors discussed in Item 1A of Avista's 2005 Form
            10-K are inherent in an investment in Avista common stock and would
            continue to be inherent in an investment in AVA common stock. These
            risk factors would be relevant to an investment decision as to
            whether or not to buy or sell Avista common stock and, after the
            effective time of the share exchange, would be relevant to the same
            decision with respect to AVA common stock.

                  However, these risk factors do not appear to be relevant to
            the decision that Avista shareholders are being asked to make. The
            holders of Avista common stock, who have already incurred the risks
            set forth in the 2005 Form 10-K by making their investment in Avista
            common stock, are now being asked to approve a holding company
            structure. The only risk factor relevant to that decision is the
            first risk factor set forth in the Proxy Statement-Prospectus. Since
            the Avista shareholders are already subject to the risk factors
            discussed in the 2005 10-K, and will continue to be so subject
            whether or not a holding company structure is adopted, those risk
            factors are not relevant to the decision as to whether to approve a
            holding company structure.

                  Accordingly, the reference in the Proxy Statement-Prospectus
            to the risk factors contained in Avista's 2005 Form 10-K has been
            deleted as not being relevant or material.



Securities and Exchange Commission
Mr. H. Christopher Owings
March 23, 2006
Page 7

      14.   Please include a risk factor describing the risks of the proposed
            share exchange and restructuring.

                  The first risk factor included in the original filing is the
            only risk factor specifically applicable to the formation of the
            holding company. It is now set forth, with minor revisions, as the
            only risk factor.

The performance of any new AVA subsidiaries is uncertain, page 7

      15.   The disclosure in this risk factor appears generic because the
            information could apply to many companies in your industry or even
            in other industries. Please revise to specifically indicate how the
            stated risk applies to your company, or delete this risk factor.

                  This seemingly generic risk factor has been deleted.

Voting Procedures, page 8

      16.   Please clarify that proxies indicating votes against a proposal will
            not be used to vote in favor of adjourning or otherwise postponing
            the meeting to allow for additional voting on the proposal.
            Otherwise, include a separate proposal describing the procedures for
            adjourning or postponing a meeting.

                  Two new paragraphs under the subheading "Adjournment" have
            been added under "VOTING PROCEDURES" disclosing that the Annual
            Meeting could be adjourned with respect to one or more matters to be
            acted upon. This new disclosure expressly indicates that proxies
            directing votes against a proposal will not be used to vote in favor
            of an adjournment to allow for the solicitation of additional votes
            in favor of that proposal, as suggested in this comment.

Proposal 1 - Election of Directors, page 9

      17.   We note disclosure indicating the board "has no reason to believe
            that any nominee will be unable to serve as a director." Please
            expand your disclosure to state, if true, that each of the nominees
            has consented to becoming a director. In addition, please file the
            appropriate written consents. Refer to Rule 438 of Regulation C.

                  The expanded disclosure has been made with respect to the
            nominees to Avista's Board of Directors. In addition, written
            consents by all current members of Avista's Board of Directors, and
            the new nominees thereto, to becoming members of AVA's Board of
            Directors have been filed as exhibits.

      18.   Please revise to include all of the information required by Item 7
            of Schedule 14A. For example, the business experience during the
            past five years for Mrs. Blake, Mr. Knight, Dr. Powell and Ms.
            Stanley is unclear. See Item 401(e) of Regulation S-K.

Mr. H. Christopher Owings

                  The disclosure has been revised as requested.

      19.   Please substantiate or delete the promotional references appearing
            in the biographical information of Ms. Stanley. For example, we note
            disclosure indicating she has held "progressively responsible
            positions of leadership" and was named one off the "Twenty-Five
            Women to Watch in Banking."

                  The "promotional" references have been deleted.

      20.   Please identify the two parties to the commercial transaction under
            the description of Mr. Eiguren's business experience.

                  The disclosure has been revised as requested.

Director and Executive Compensation, page 17

      21.   Please disclose whether the vesting schedule of options issued to
            executive officers will accelerate as a result of the company's
            restructuring.

                  The formation of the holding company will not accelerate the
            vesting of options or other awards granted to executive officers. An
            additional paragraph to this effect has been added to "Executive
            Compensation and Employee Benefit Plans", on page 55, which is
            within the discussion of Proposal 2.

Class Action Securities Litigation, page 29

      22.   To the extent possible, please update the current status of the
            legal proceedings discussed in this section. Please also explain to
            us why you do not expect that this lawsuit will have a material
            adverse effect on your financial condition, results of operations or
            cash flows. We may have further comment after reviewing your
            response.

                  Update on the Proceedings: On July 30, 2004, the Court entered
            an Order denying the Defendants Motion to Dismiss the Plaintiffs'
            Consolidated Amended Class Action Complaint ("CAC"). The Defendants
            filed a Motion to Reconsider on June 13, 2005. On October 19, 2005,
            the Court entered an Order granting Defendants' Motion to Reconsider
            and dismissed the Plaintiffs' CAC with leave to amend. The
            Plaintiffs filed a Second Amended Class Action Complaint ("SCAC") on
            November 10, 2005. The Defendants filed a Motion to Dismiss the SCAC
            on January 6, 2006, and the Motion is fully briefed and set for oral
            hearing on April 14, 2006.

                  Explanation of Avista's Opinion: In Avista's opinion the
            lawsuit should not have a material adverse effect on its financial
            condition, results of operations or cash flows because Plaintiffs
            fail to allege loss causation under the standard set out in

            Dura Pharmaceuticals, Inc. v. Broudo, 125 S. Ct. 1627, 161 L. Ed. 2d
            577 (2005). In dismissing the CAC, the judge noted that to state a
            claim for securities fraud under Section 10(b) of the Exchange Act
            and Rule 10b-5, a plaintiff must plead, among other things, loss
            causation, which is "a causal connection between the material
            misrepresentation and the loss". Dura Pharmaceuticals, 125 S. Ct. at
            1631 (citing 15 U.S.C. Section 78u-4(b)(4)). The Court noted that
            alleging purchase price inflation, as the Plaintiffs did, is
            insufficient to establish loss causation. The judge also noted that
            in addition to purchase price inflation, the Plaintiffs argued they
            pled loss causation by alleging that they were damaged when the FERC
            announced two Orders, on June 4 and August 13, 2002, following which
            the price of Avista stock dropped. The Court rejected this argument
            because the Plaintiffs failed to allege facts showing the drops in
            Avista's stock price following the announcement of the FERC's orders
            were caused by disclosure of Avista's alleged misrepresentations.
            The Court found that the FERC orders did not reveal any factual
            information showing Avista illegally manipulated the energy market
            or made the factual misrepresentations alleged in the CAC, and that
            the FERC orders did not provide a basis for asserting a causal
            relationship between Avista's alleged fraud and Plaintiffs' alleged
            economic loss.

                  Based on Avista's review of the SCAC, it is Avista's opinion
            that the SCAC does not contain any additional factual allegations,
            that were not contained in the CAC, that substantively support loss
            causation under the Dura standard, and that the SCAC should,
            therefore, be dismissed for failure to state a claim. Avista cannot
            predict the Court's ruling, but it is Avista's opinion that the
            Court should dismiss the SCAC for the same reasons it dismissed the
            CAC.

Reasons for Holding Company Proposal, page 34

      26.   Please balance your disclosure of the potential benefits of the
            proposed restructuring with equally prominent disclosure of
            potential negative consequences of the proposal.

                  A subheading entitled "Possible Negative Consequences" has
      been added under the heading "Reasons for Holding Company Proposal".

      27.   We note that the holding company structure would permit the use of
            financing techniques by non-utility businesses. Please describe in
            greater detail the financing techniques to which you refer.

                  The discussion under "Reasons for Holding Company Proposal --
            Benefits" has been revised to eliminate references to "financing
            techniques" and to focus on the fact that AVA would have
            considerably more flexibility in making capital contributions to its
            subsidiaries than does Avista. This is primarily because Avista's
            securities issues are subject to prior regulatory approval and the
            proceeds of Avista's securities issues may not be used to make
            contributions to subsidiaries. AVA would not be so limited.

      28.   We note disclosure on page 34 indicating that the holding company
            structure would make it easier for AVA to enter into new businesses
            within other sectors of the energy industry. We also note disclosure
            on page 37 indicating that after the effective time of the share
            exchange, AVA may form new subsidiaries that may engage in
            businesses that are not related to the energy business. Please
            identify and describe the businesses you contemplate entering into.

                  The reference to the energy sector has been eliminated.

                  The disclosure under "Business of AVA" has been clarified. The
            Avista Board of Directors currently intends to limit future
            investments in the Other business segment, as disclosed in the 2005
            10-K, and has no present intention of entering into any new lines of
            business.

Amendment or Termination of Plan of Exchange, page 37

      29.   Please explain why you are unable to predict under what
            circumstances the share exchange might be terminated or abandoned.
            We may have further comment after reviewing your response.

                  The disclosure has been revised to give some examples of
            circumstances which could warrant termination or abandonment of the
            Plan of Exchange.

            disclosure are the opinions of Heller Ehrman. It is not appropriate
            to require investors to determine which portions of the disclosure
            are statements of law and conclusions of law.

Listing of AVA Common Stock, page 46

            with the completion of the share exchange.

      38.   Please provide support for the qualitative and comparative
            statements that appear in this section. Please mark your support or
            provide page references in your response to the sections you rely
            upon for each specific statement. To the extent you are unable to
            provide support, please delete the qualitative and comparative

            -     Avista Utilities expects to continue to be among the industry
                  leaders in performance, value and service in its electric and
                  natural gas utility business.

            -     Based on Avista Utilities' forecast for electric customer
                  growth of 2.5 percent and natural gas customer growth of 4
                  percent within its service area, Avista Utilities anticipates
                  retail electric and natural gas load growth will average
                  between 3 and 3.5 percent annually for the next four years.

                  There are multiple sources of information with respect to
            first item.

                  With respect to service-related performance, Avista
            periodically benchmarks its operations for power quality and
            reliability, as well as customer service and satisfaction. In
            particular, a recent external study has found Avista to be strong in
            power quality and reliability as well as customer service. Please
            see pages 8 and 9 of the "2005 Electric Utility Residential Customer
            Satisfaction Study" which is being furnished to the Staff under
            separate cover as supplemental information. Avista has omitted
            certain pages, which provide specific data about companies other
            than Avista that is not publicly available and Avista does not have
            permission to distribute.

                  In addition, for 2005, Avista exceeded its internal targets
            with a customer satisfaction rating of 93 percent. Please see the
            "Voice of the Customer Overall Customer Satisfaction" that presents
            internally prepared statistics for period from 2000 through 2006
            (YTD), which is being furnished to Staff under separate cover as
            supplemental information.

                  With respect to shareholder value-related performance,
            Avista's common stock has performed at the 67th percentile among the
            S&P 400 MidCap Utilities Index during the period from January 1,
            2003 to December 31, 2005. Please see the report from an independent
            consultant, which is being furnished to Staff under separate cover
            as supplemental information. During this period, Avista's total
            market capitalization increased from $560 million to $860 million.
            Avista's market capitalization has increased to over $950 million as
            of March 20, 2006.

                  Avista has also benchmarked its utility operations against its
            peers and determined that Avista is strong in distribution and
            transmission operations, as well as hydro operations. Please see
            pages 10, 12, 28 and 30 of the " 2005 Benchmarking Update" which is
            being furnished to the Staff under separate cover as supplemental
            information.

                  The statements in Avista's 2005 Form 10-K regarding customer
            growth and load growth, which have been noted by Staff, are based on
            Avista's internal forecast and analysis. A copy of relevant portions
            of such forecast and analysis is being furnished to the Staff under
            separate cover as supplemental information.

                  In future filings, Avista plans to limit its qualitative and
            comparative statements, although Avista will continue to disclose
            forecasted customer growth and load growth as is customary in the
            utility industry.

                  The documents being furnished to the Staff in response to this
            comment, namely,

Item 7. Management's Discussion and Analysis of Financial Condition, page 24

      39.   Please explain to us, and in future filings discuss, in reasonable
            detail any known material trends and uncertainties that will have or
            are reasonably likely to have a material impact on your revenues or
            income or result in your liquidity decreasing or increasing in any
            material way. For example, if relevant, you may discuss the evolving
            trends in each segment of your business, the nature of your
            competition, and the consumer demands for your products and services
            in the geographical markets where you operate and the trends that
            would affect each segment. In doing so, provide additional
            information about the quality and variability of your earnings and
            cash flows so that investors can ascertain the likelihood of the
            extent past performance is indicative of future performance. In
            addition, discuss in reasonable detail the material opportunities,
            challenges and risks in the short and long term and the specific
            actions you are taking to address each. Please refer to SEC Release
            No. 33-8350.

                  Avista has made efforts to follow the guidance in SEC Release
            No. 33-8350 with respect to known material trends and uncertainties
            that will have or are reasonably likely to have a material impact on
            Avista's revenues, income or liquidity. Examples of such disclosures
            include, but are not limited to: 1) the "Executive Level Summary" on
            pages 27-29 that includes discussion of the dependency of Avista
            Utilities' financial performance upon weather conditions, wholesale
            market conditions and regulatory decisions, expected utility growth
            rates, future capital expenditures and the primary factors causing
            volatility of Avista Energy's results 2) "Avista Utilities -
            Regulatory Matters" on pages 29-31 that includes disclosure of

            recent rate changes 3) "Overall Liquidity" on pages 50-51 that
            includes disclosure of hydroelectric conditions and increasing
            commodity costs and 4) "Avista Utilities Operations" on page 55 that
            includes disclosure of future debt maturities and capital
            expenditures. In future filings, Avista will continue to consider
            the guidance of SEC Release No. 33-8350 with a view to enhancing its
            disclosures with respect to known material trends and uncertainties.

Executive Level Summary, page 27

      40.   We note your disclosure indicating that Avista Utilities operating
            and financial performance is substantially dependent upon, among
            other things, weather conditions, the price of natural gas and
            electricity in the wholesale market and weather conditions. Please
            tell us, and in future filings describe more specifically, how these
            factors affect your operating and financial performance.

                  In "Item 1A. Risk Factors" (page 16), Avista has disclosed in
            detail how weather conditions and commodity price risk can affect
            its results of operations, financial condition and cash flows. In
            future filings, Avista will enhance its disclosures in "Item 7.
            Management's Discussion and Analysis of Financial Condition and
            Results of Operations" with respect to weather conditions and the
            price of natural gas and electricity in the wholesale market to
            provide summarized disclosures of the information provided in "Item
            1A. Risk Factors."

Capital Resources, page 51

      41.   Please tell us, and in future filings discuss, the anticipated
            effects, if any, that the proposed restructuring of the company will
            have on future compliance with the financial covenants discussed in
            this section.

                  Avista does not expect the proposed reorganization to affect
            the compliance with the ratio of "earnings before interest, taxes,
            depreciation and amortization" to "interest expense" of Avista
            Utilities. The ratio is currently measured at the Avista Utilities
            level and will continue to be measured at that level in the future.

                  The ratio of "consolidated total debt" to "consolidated total
            capitalization" is currently measured at the Avista Corp. level.
            Once the proposed reorganization is complete, the ratio will be
            measured at the Avista Utilities level. The "Avista Capital
            Dividend" will result in a reduction in common equity and a
            corresponding increase in the ratio. However, the expected increase
            in the ratio is not expected to breach the covenant and such ratio
            is expected to start declining in 2006.

                  Avista is currently in the process of negotiating a new credit
            facility, which may offer more favorable pricing. In addition,
            Avista and its lenders are also discussing the feasibility of
            increasing the permissible debt-to-capitalization ratio for a
            temporary period as a precautionary measure.

                  Avista will provide disclosure of these ratios and any changes
            in the covenants in future filings.

Financial Statements

Consolidated Statements of Cash Flows, page 69

      42.   Please explain how you classify AFUDC in the statement of cash
            flows. Please tell us what portion of the allowance relates to
            equity funds versus capitalized interest expense incurred. If you
            exclude AFUDC from investing activities, please explain your basis.
            Please see footnote 7 to SFAS no. 95. On a different note, can you
            show us how the AFUDC rate is determined and explain the "maximum
            allowable rates" referred to under AFUDC.

                  Avista classifies AFUDC (both the equity and debt portions)
            amounts as non-cash regulatory adjustments representing the cost of
            both the debt and equity funds used to finance utility plant
            additions during the construction period. The amount does not
            reflect cash paid for utility property capital expenditures. As a
            result, AFUDC is subtracted from net income in arriving at operating
            cash flows and from utility property capital expenditures in
            arriving at investing cash flows. For the year ended December 31,
            2005, the equity component of AFUDC was $1.4 million and the debt
            component was $1.7 million. Upon further review of SFAS No. 95
            (specifically footnote 7 to paragraph 17c as referred to by the
            Staff), Avista may consider classifying the debt component of AFUDC
            as utility capital expenditures in the investing activities section
            of its statement of cash flows. Avista will review industry
            practices and consult with certain peer companies in reaching its
            final conclusion. The debt component amounts are $1.7 million, $1.4
            million and $1.1 million for the years ended December 31, 2005, 2004
            and 2003, respectively. In each year, this represents an immaterial
            portion (less than 1.5%) of both operating and investing cash flows.
            As such, Avista does not plan to amend its 2005 Form 10-K, but may
            change this classification in future periods.

                  The total AFUDC rate is determined based on the overall rate
            of return allowed by regulators in Avista's primary regulatory
            jurisdiction (Washington), which is the maximum allowable rate. This
            rate was 9.72 percent for 2005, 2004 and 2003.

Notes to Financial Statements

Note 1. Summary of Significant Accounting Policies, Page 72

Other Non-Utility Revenues. Page 73,

      43.   We presume you are recognizing revenues from the Advanced
            Manufacturing and Development operations when products are shipped
            to customers rather than upon delivery of the product to your
            customers based on the risk of loss as dictated by your shipping
            terms. Please tell us and disclose your shipping terms. If shipment
            is not when all of the risks and rewards of ownership are
            transferred to the customer, provide your basis in GAAP for your
            revenue recognition policy.

                  The point at which the risk of loss transfers to the customer
            is at the time of shipment with the exception of sales that are
            delivered with AM&D's vehicles. However, substantially all of these
            sales would be delivered on the same day as shipment. Revenues in
            2005 from AM&D totaled $17.1 million, or less than 1.3 percent of
            total consolidated revenues for Avista. The total gross profit on
            these sales was $1.2 million. Avista will enhance its disclosures
            in future filings to discuss the  transfer of risk of loss that
            generally occurs upon shipment.

Foreign Currency Translation Adjustment, Page 74

      44.   Your disclosure suggests that Avista Energy Canada, Ltd.'s
            functional currency is the Canadian dollar. Please address the
            salient economic factors that support this conclusion pursuant to
            paragraph 42 of SFAS No. 52.

                  Substantially all of Avista Energy Canada's activities involve
            the providing of natural gas service to end-user industrial and
            commercial customers in British Columbia, Canada with the natural
            gas supplies also coming from Canadian sources. These transactions
            are denominated in Canadian dollars. Avista has considered the
            salient economic factors described in paragraph 42 of SFAS No. 52
            and has concluded that the Canadian dollar is the appropriate
            functional currency for the operations for Avista Energy Canada
            based on the following:

                  1.    Cash flow indicators

                  Cash flows related to Avista Energy Canada's individual assets
            and liabilities are primarily in Canadian dollars and do not
            directly impact the parent's cash flows.

                  2. Sales price indicators


Securities and Exchange Commission
Mr. H. Christopher Owings
March 23, 2006
Page 18

                  Sales prices for Avista Energy Canada's products are not
            primarily responsive on a short-term basis to changes in exchange
            rates but are determined more by local competition.

                  3. Sales market indicators

                  There is an active local sales market for Avista Energy
            Canada's products.

                  4. Expense indicators

                  Labor, materials, and other costs for Avista Energy Canada's
            products or services are primarily local costs, even though there
            are imports from the US.

                  5. Financing indicators

                  Funds generated by Avista Energy Canada's operations are
            sufficient to service existing and normally expected debt
            obligations.

                  6. Intercompany transactions and arrangements indicators

                  There is not an extensive interrelationship between the
            operations of Avista Energy Canada and its parent. However, Avista
            Energy Canada does rely on its parent's competitive advantages
            regarding the purchase of natural gas.

                  Avista supplementally advises the Staff that the total amount
            included in accumulated other comprehensive income was a gain of
            $1.4 million as of December 31, 2005 and the change included in
            comprehensive income for the year ended December 31, 2005 was $0.3
            million, both of which are immaterial to Avista.

Depreciation

      45.   Please explain to us how the hydroelectric depreciation rates
            include annuity and interest components. In this regard, an example
            may be informative.

                  The calculation is comprised of two components. The first
            component is the annuity amortization expense, which is calculated
            by multiplying the depreciable hydroelectric plant by an annuity
            factor determined through a depreciation study and approved by
            Avista's regulators for use in setting rates to customers. The
            second component is the interest component, which is calculated by
            multiplying the depreciation reserve for the respective
            hydroelectric plant asset by an interest rate. Avista's current
            interest rate for hydroelectric facilities is 9%. This rate was also
            determined through a depreciation study and approved by Avista's
            regulators for use in setting rates to customers. The two components
            are added together to determine depreciation expense. Avista's
            regulators have consistently used this calculation method.

Note 12. Pension Plans and Other Postretirement Benefit Plans, page 86

      46.   Please explain to us how you calculate the market related value of
            plan assets as that term is defined in SFAS 87. Since there is an
            alternative to how you can calculate this item, and it has a direct
            effect on pension expense, we believe you should disclose how you
            determine this amount in accordance with paragraph 12 of APB 22.

                  The "market-related value" of plan assets is calculated using
            the "fair market value" of the assets as opposed to a "calculated
            value" that recognizes changes in fair value in a systematic and
            rational manner over not more than five years. As disclosed on page
            87 of the 2005 Form 10-K:

                  "The fair value of pension plan assets invested in debt and
            equity securities was based primarily on market prices. The fair
            value of pension plan assets invested in real estate was determined
            based on three basic approaches: (1) current cost of reproducing a
            property less deterioration and functional economic obsolescence (2)
            capitalization of the property's net earnings power; and (3) value
            indicated by recent sales of comparable properties in the market.
            The fair value of plan assets was determined as of December 31, 2005
            and 2004."

                  Avista will revise its disclosure in future filings to make it
            more clear that it uses "fair market value" to determine the
            market-related value of its plan assets used to calculate expected
            return on assets.

Note 18. Interest Rate Swap Agreements, page 94

      47.   We are unclear on what your accounting will be in the event
            regulatory accounting orders arc not obtained prior to mandatory
            cash settlements of your interest rate swaps. Please help us
            understand your accounting and whether lack of an accounting order
            would cause the amounts included in other comprehensive income to be
            reclassified to the net income versus a regulatory liability. You
            may want to provide us a step-by-step analysis of the transaction(s)
            and the related accounting and rationale for such accounting at each
            step. On a related note, it appears you classify the cash flows
            associated with hedges of anticipated debt issuances as a financing
            activity. Please explain to us in detail the basis for your
            classification in this statement. We may have further comment.

                  Because Avista does not have regulatory accounting orders for
            unrealized gains or losses related to these forward-starting
            interest rate swaps (prior to mandatory cash settlement), Avista has
            concluded that it is not appropriate under the provisions of SFAS 71
            to reflect a regulatory asset or liability for these unrealized
            gains or losses prior to realization. As a result, the unrealized
            gains and losses are recorded as adjustments to other comprehensive
            income or loss in accordance with SFAS No. 133 for cash flow hedges.



Securities and Exchange Commission
Mr. H. Christopher Owings
March 23, 2006
Page 20

                  Upon cash settlement of the interest rate swaps, the realized
            gain or loss is/will be reclassified out of accumulated other
            comprehensive income/loss, deferred as a regulatory asset or
            liability (as part of long-term debt) and amortized over the life of
            the debt issued. This is consistent with Avista's historical
            regulatory accounting practices for all debt-related costs,
            including issuance costs, realized gains and losses on the
            repurchase of debt prior to scheduled maturity and cash settlement
            of interest rate swaps. Avista believes this accounting treatment
            for the realized gains or losses is consistent with the provisions
            of SFAS No. 71 and has never been disallowed by any of Avista's
            regulators.

                  With respect to Avista's classification of the mandatory cash
            settlement of the interest rate swaps as a financing activity,
            Avista considered the provisions of paragraph 6 of SFAS 104. This
            guidance allows cash allows from contracts that are hedges to be
            classified in the same category on the statement of cash flows as
            the cash flows from the item being hedged. The forecasted debt
            issuance that was hedged by the forward-starting interest rate swap
            was issued during 2005 and the related swap was settled. Avista also
            considered by analogy the guidance in EITF 95-13, which indicates
            that debt issuance costs should be classified as financing
            activities. Finally, Avista considered that the effect of these
            forward-starting mandatory cash settled interest rate swaps is
            similar to a premium or discount, which are treated as financing
            activities. Based on the above considerations, both the proceeds
            from the debt issuance and the cash received on the swap settlement
            were classified as financing. Avista will enhance its disclosure in
            future filings to clarify its accounting policy for these items.

Note 26. Commitments and Contingencies, page 100

California Refund Proceeding

      48.   You state that based on information currently known to your
            management, you do not expect that the California refund proceeding
            will have a material adverse effect on your financial condition,
            results of operations or cash flows due to netting against
            counterparty defaults. Please tell us your legal basis for assuming
            that any refunds you may be obligated to make will be offset by
            amounts owed to you. Further, tell us your basis in GAAP for
            offsetting a contingent liability with a contingent recovery. If
            not, then you should revise your assessment of materiality to
            eliminate netting the amounts of potential refunds against
            counterparty defaults. Please revise or advise.

                  Avista has based this assumption on the specific language of
            Federal Energy Regulatory Commission (FERC) orders each of which has
            stated that any refunds will be offset against unpaid amounts owed
            to the respective parties. In particular, 112 FERC Paragraph 61,176
            (Docket EL00-95-000 and Docket No. EL00-98-000) issued August 8,
            2005, paragraph 115 states:



Securities and Exchange Commission
Mr. H. Christopher Owings
March 23, 2006
Page 21

                  "After taking into account comments concerning the
            complications that might ensue from issuing refunds piecemeal,
            including the difficulty of ensuring adequate funds to cover cost
            filings, we will require the resolution of the cost filings prior to
            issuance of any refunds. In reaching this determination, we are
            particularly mindful of the CAISO's "administrative nightmare"
            objections to our proposed two-phase approach, since the CAISO must
            perform the task of finalizing the refunds as well as settle and
            clear current ISO market activity and perform other vital daily
            functions. We further find that resolving cost filings prior to
            issuing refunds is consistent with our prior statement that refunds
            will be offset by amounts still owed as determined in this
            proceeding, and only the net result of this offset will flow to or
            from parties. Parties are required to submit to the Commission their
            cost filings no later than September 10, 2005. The technical
            conference we establish below should hasten resolution of the cost
            filings as expeditiously as practicable."

                  Also, (105 FERC P 61,066 at paragraph 180 issued October 16,
            2003) states:

                  "it is a settled matter that refunds will be offset against
            amounts still owed as determined in this proceeding. The very
            concept of an offset precludes any possibility that sellers would be
            required to remit refunds to buyers without first netting out
            amounts still owed to sellers. Accordingly, it is also a settled
            matter that amounts owed both by and to parties, as determined in
            this proceeding, will be offset against each other and only the net
            result of this offset will flow to or from parties. No further
            clarification is required."

Northeast Combustion Turbine Site

      49.   Please tell us whether your accrual of the estimated clean-up costs
            during 2005 was made without consideration of any potential recovery
            of clean-up costs from Co-op and the engineering firm whom you refer
            to in this note. Please also tell us the extent to which you may
            have considered potential rate recovery of such clean up costs in
            your materiality assumptions. Refer to SAB Topic 10:F.

                  Avista did not reduce or offset its accrued liability for the
            estimated cleanup costs for any potential recoveries from Co-op or
            the engineering firm referred to in Note 26 of its financial
            statements. Avista also did not reduce its accrued liability for any
            potential rate recovery as it determined that such potential
            recovery did not meet the criteria in paragraph 9 of SFAS No. 71.
            Furthermore, Avista has not recorded any gain contingency related to
            potential recovery.

Item 9A. Controls and Procedures

      50.   We note your statement that disclosure controls and procedures can
            only provide "reasonable assurance" of achieving their control
            objectives. In future filings,

            Part II.F.4 of Final Rule Release 33-8238.

                  Avista will revise future filings to state that its disclosure
            controls and procedures are effective at a "reasonable assurance"
            level.
