(b) The Representatives shall be furnished with opinions, dated the Closing Date, of Xxxxx Day; Hinkle, Hensley, Xxxxxx & Xxxxxx L.L.P.; Rainey, Ross, Rice & Xxxxx; and Xxxxxxxx & Xxxxxxx, counsel for the Company, substantially in the forms included as Exhibits A, B, C and D respectively;

(c) The Representatives shall have received from Xxxxx Xxxxxxxxxx LLP, counsel for the Underwriters, such opinion or opinions dated the Closing Date with respect to such matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters;

(d) The Company shall have furnished to the Representatives a certificate of the President or any Vice President of the Company, dated the Closing Date, as to the matters set forth in clause (a) and (h) of this Section 6 and to the further effect that the signers of such certificate have carefully examined the Registration Statement, the Prospectus, the Time of Sale Information and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date; and

(ii) since the date of the most recent financial statements included or incorporated by reference in the Prospectus and the Time of Sale Information, there has been no material adverse change in the condition of the Company, financial or otherwise, or in the earnings, affairs or business prospects of the Company, whether or not arising in the ordinary course of business, from that set forth or contemplated by the Registration Statement, the Time of Sale Information on the Prospectus;

(e) The Representatives shall have received letters from Deloitte & Touche LLP, independent public accountant for the Company (dated the date of this Agreement and Closing Date, respectively, and in form and substance satisfactory to the Representatives) advising that (i) they are an independent registered public accounting firm with respect to the Company as required by the Act and published rules and regulations of the Commission thereunder, (ii) in their opinion, the financial statements and supplemental schedules incorporated by reference in the Registration Statement, the Time of Sale Information or Prospectus and covered by their opinion filed with the Commission under Section 13 of the Exchange Act comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the published rules and regulations of the Commission thereunder, (iii) they have performed limited procedures, not constituting an audit, including a reading of the latest available interim financial statements of the Company, a reading of the minutes of meetings of the Board of Directors, committees thereof, and of the Shareholder of the Company since the date of the most recent audited financial statements included or incorporated by reference in the Prospectus and the Time of Sale Information, inquiries of officials of the Company responsible for financial accounting matters and such other inquiries and procedures as may be specified in such letter, and on the basis of such limited review and procedures nothing came to their attention that caused them to believe that: (A) any material modifications should be made to any unaudited financial statements of the Company included or incorporated by reference in the Registration Statement, the Time of Sale Information or Prospectus for them to be in conformity with generally accepted accounting principles or that any unaudited consolidated financial statements of the Company included or incorporated by reference in the Registration Statement, the Time of Sale Information or Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the rules and regulations of the Commission applicable to Form 10-Q; (B) with respect to the period subsequent to the date of the most recent financial statements included or incorporated by reference in the Prospectus and except as set forth in or contemplated by the Registration Statement, the Time of Sale Information or Prospectus, there were any changes, at a specified date not more than five Business Days prior to the date of the letter, in the capital stock of the Company, increases in

long-term debt or decreases in stockholders’ equity or net current assets of the Company as compared with the amounts shown on the most recent consolidated balance sheet included or incorporated in the Prospectus and the Time of Sale Information, or for the period from the date of the most recent financial statements included or incorporated by reference in the Prospectus and the Time of Sale Information to such specified date there were any decreases, as compared with the corresponding period in the preceding year, in operating revenues, operating income or net income of the Company, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives; and (iv) they have carried out specified procedures performed for the purpose of comparing certain specified financial information and percentages (which is limited to financial information derived from general accounting records of the Company or, to the extent not so derived, from schedules prepared by Company officers responsible for such accounting records) included or incorporated by reference in the Registration Statement, the Time of Sale Information and Prospectus with indicated amounts in the financial statements or accounting records of the Company and (excluding any questions of legal interpretation) have found such information and percentages to be in agreement with the relevant accounting and financial information of the Company referred to in such letter in the description of the procedures performed by them;

(f) Subsequent to the respective dates as of which information is given in the Registration Statement, Time of Sale Information and the Prospectus, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Registration Statement, the Time of Sale Information and Prospectus the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgement of the Representatives, material and adverse and makes it impracticable or inadvisable to market the Debt Securities as contemplated by the Prospectus and the Time of Sale Information;

(g) Subsequent to the date hereof, there shall not have been any decrease in the rating or outlook of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g)(2) under the Act) or any public announcement of any intended or potential decrease in any such rating or outlook or of a possible change in any such rating or outlook that does not indicate the direction of the possible change;

(h) The Company shall have complied with the provisions of Section 4(c) hereof with respect to the furnishing of prospectuses;

(i) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and their counsel, this Agreement and all obligations of the Underwriters hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing, or by telephone or telegraph confirmed in writing.

7. Conditions of Company’s Obligations. The obligations of the Company to sell and deliver the Debt Securities are subject to the following conditions:

(a) Prior to the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or the Representatives, threatened;

(b) At the Closing Date, the order of the New Mexico Public Regulation Commission authorizing and approving the issuance and sale of the Debt Securities shall be final and in full force and effect and the time for appeal therefrom or review thereof or intervention with respect thereto shall have expired.

If any of the conditions specified in this Section 7 shall not have been fulfilled, this Agreement and all obligations of the Company hereunder may be cancelled on or at any time prior to the Closing Date by the Company. Notice of such cancellation shall be given to the Underwriters in writing or by telephone or facsimile transmission confirmed in writing.

8. Reimbursement of Underwriters’ Expenses. If the sale of the Debt Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally upon demand for all out-of-pocket expenses that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Debt Securities, including the reasonable fees and disbursements of counsel for the Underwriters.

9. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, members, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, in the Time of Sale Information or Issuer Free Writing Prospectus or in the Prospectus or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement or any amendment thereto, in the Time of Sale Information or any Issuer Free Writing Prospectus or in the Prospectus or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein; provided, further, that with respect to any such untrue statement in or omission from any Time of Sale Information or Issuer Free Writing Prospectus, the indemnity contained in this paragraph (a) shall not inure to the benefit of any Underwriter or its directors, members, officers, employees and agents, and each person, if any, who controls such Underwriter to the extent that the sale to the person asserting any such loss, claim, damage or liability was an initial sale by such Underwriter and any such loss, claim, damage or liability of or with respect to such Underwriter results from the fact that both (i) to the extent required by applicable law, a copy of all of the Time of Sale Information (including each Issuer Free Writing Prospectus specified in Schedule IV) was not sent or given to such person at or prior to the sale of the Debt Securities to such person and (ii) the untrue statement in or omission from such Time of Sale Information or Issuer Free Writing Prospectus was corrected in the undelivered Time of Sale Information unless, in either case, such failure to deliver all of the Time of Sale Information was a result of non-compliance by the Company with the provisions of Section 4(c) hereof. This indemnity agreement will be in addition to any liability which the Company may otherwise have;

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, and each of its directors, officers, employees and agents, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the Registration Statement or any amendment thereto, Time of Sale Information or in the Prospectus or any amendment or supplement thereto. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have. The Company acknowledges that the statements set forth in [•] in the Time of Sale Information and Prospectus constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Prospectus (or any amendment or supplement thereto);

(c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party; it being understood, however, that in each case the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such indemnified parties, which firm shall be designated by the Representatives if the indemnified parties consist of the Underwriters or their directors, members, officers, employees or agents. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding;

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 9 is for any reason held to be unenforceable by an indemnified party although applicable in accordance with its terms, the Company and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating

or defending same) (collectively, “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Debt Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among the Underwriters relating to the offering of the Debt Securities) be responsible for any amount in excess of the purchase discount or commission applicable to the Debt Securities purchased by such Underwriter hereunder; provided, further, that each Underwriter’s obligation to contribute to Losses hereunder shall be several and not joint. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions in each case set forth on the cover of the Prospectus Supplement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, member, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer, director, member, employee or agent of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

10. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Debt Securities agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Debt Securities set forth opposite their names in Schedule I hereto bear to the aggregate principal amount of Debt Securities set forth opposite the names of all the remaining Underwriters) the Debt Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Debt Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Debt Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Debt Securities, and if such nondefaulting Underwriters do not purchase all the Debt Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date may be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or any amendment or supplement to either thereof, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. It is understood that any such postponement, change, amendment and/or supplement may require the establishment of a new “time of sale” and new “time of sale information”. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement. Nothing

contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or any nondefaulting Underwriter for damages occasioned by its default hereunder.

11. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Debt Securities, if at any time after the date hereof and prior to the delivery of and payment for the Debt Securities (i) trading in the common stock of Xcel Energy Inc. shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange; (ii) a banking moratorium shall have been declared either by Federal or New York State authorities; (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the United States or Europe; or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Debt Securities as contemplated by the Time of Sale Information and Prospectus.

12. Indemnities to Survive Delivery. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of their respective officers, directors or controlling persons within the meaning of the Act, and will survive delivery of and payment for the Debt Securities. The provisions of Sections 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

13. Notices. All communications hereunder will be in writing and, if sent to the Representatives, will be mailed, delivered or transmitted and confirmed to them at their address set forth for that purpose in Schedule 1 hereto or, if sent to the Company, will be mailed, delivered or transmitted and confirmed to it at Tyler at Xxxxx Xxxxxx, Xxxxxxxx, Xxxxx 00000, attention Secretary. All communications shall take effect at the time of receipt thereof.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 9 hereof, and no other person will have any right or obligation hereunder.

15. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

16. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same instrument.

17. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof.

18. Other. As used herein, “Business Day” shall mean any day other than a Saturday, a Sunday or a legal holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in the City of New York.

19. Underwriters Counsel. The Company and the Underwriters acknowledge that Xxxxx Xxxxxxxxxx LLP (a) is acting as counsel to the Underwriters in connection with this Agreement and the transactions contemplated hereby and (b) has acted, and may continue to act, as counsel to the Company’s parent company, Xcel Energy Inc., and certain of its subsidiaries in connection with certain regulatory matters, and the Company and the Underwriters consent to such representation.

Re:		$[•] principal amount of Debt Securities, Series due [•],
		[•]% of Southwestern Public Service Company, a New Mexico corporation.

Ladies and Gentlemen:

We have acted as special counsel to Southwestern Public Service Company, a New Mexico Corporation (the “Company”), in connection with the purchase from the Company by the Underwriters named in Schedule II to the Underwriting Agreement, dated [•] (the “Underwriting Agreement”), by and between the Company and you, as Representatives of the several Underwriters named on Schedule II thereto (the “Underwriters”), of $[•] aggregate principal amount of Series [•] Debt Securities, [•]% due [•] (the “Debt Securities”), being issued on this date under the Company’s Indenture, dated as of February 1, 1999, as heretofore supplemented by the First Supplemental Indenture, dated as of February 1, 1999, the Second Supplemental Indenture, dated as of October 1, 2001, the Third Supplemental Indenture, dated as of October 1, 2003, and as it is being further supplemented by a supplemental indenture creating the Debt Securities all from the Company to JPMorgan Chase Bank, N.A., as successor to The Chase Manhattan Bank, as trustee (the “Trustee”) (said indenture, as so supplemented, being hereinafter referred to as the “Indenture”). This opinion is furnished to the Representatives, as representatives for the Underwriters pursuant to Section 6(b) of the Underwriting Agreement. Terms used in this opinion that are defined in the Underwriting Agreement are used as so defined.

In connection with the opinions and views expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of this opinion. Based upon the foregoing and subject to the further assumptions, qualifications and limitations stated herein, we are of the opinion that:

1. Assuming that the Underwriting Agreement has been duly (a) authorized by the Company and (b) executed and delivered by the Company under New Mexico law, the Underwriting Agreement has been duly executed and delivered by the Company to the extent such execution and delivery are matters of New York law.

2. Assuming that the Indenture has been duly (a) authorized by the Company and (b) executed and delivered by the Company under New Mexico law, the Indenture has been duly executed and delivered by the Company to the extent such execution and delivery are matters of New York law, and, assuming further that the Indenture (c) has been duly authorized, executed and delivered by the Trustee and (d) does not violate New Mexico law, the Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms; the Indenture conforms in all material respects to the description thereof in the Prospectus.

3. Assuming that the issuance and sale by the Company of the Debt Securities pursuant to the Underwriting Agreement have been duly authorized by all necessary corporate action on the part of the Company, when duly executed by the Company, authenticated by the Trustee and delivered to the Underwriters pursuant to the Underwriting Agreement against payment of the consideration therefor specified therein, the Debt Securities will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

A-1

The Debt Securities are in the form contemplated by the Indenture and conform in all material respects to the description thereof in the Prospectus.

4. The Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

5. The Company is not, and after giving effect to the offering and sale of the Debt Securities and the application of the proceeds thereof as described in the Prospectus will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

6. Assuming that the issuance and sale of the Debt Securities have been duly authorized and approved by an order of the New Mexico Public Regulation Commission and such order is final and in full force and effect on the date hereof, and that the time for appeal therefrom or review thereof or intervention with respect thereto have expired, no consent, approval, authorization or order of, or filing, registration or qualification with, any governmental agency or body or any court is required under federal or New York law in connection with the execution, delivery or performance of the Indenture or the Underwriting Agreement, or in connection with the issuance or sale of the Debt Securities by the Company, (a) except those that already have been obtained and are in full force and effect and (b) other than as may be required under New York securities or blue sky laws.

7. The execution, delivery and performance of the Indenture and the Underwriting Agreement by the Company, the issuance and sale of the Debt Securities by the Company and the compliance with the terms and provisions thereof by the Company will not violate any federal or New York law or regulation that to our experience is generally applicable to a transaction of the type contemplated by the Underwriting Agreement, or any order or decree of any court or governmental agency that is binding upon the Company or its property, or conflict with or result in a default under any of the terms or provisions of any agreement to which the Company is a party or bound (this opinion being limited, (a) to those orders, decrees and agreements listed on Exhibit A attached hereto (“Material Agreements”), which the Company has represented are all material orders, decrees and agreements applicable to the Company, and (b) in that we express no opinion with respect to any violation (1) not readily ascertainable from the face of any such order, decree or agreement, (2) arising under or based upon any cross default provision insofar as it relates to a default under an agreement not so identified on Exhibit A attached hereto or (3) arising as a result of any violation of any agreement or covenant by failure to comply with any financial or numerical requirement requiring computation).

8. The statements contained in the Prospectus under the captions “Description of the Debt Securities” and “Supplemental Description of Debt Securities,” insofar as such statements purport to summarize the legal matters or provisions of documents referred to therein, present fair summaries of such legal matters and documents.

9. The descriptions in the Prospectus of United Stated federal statues, insofar as such descriptions purport to summarize such federal statutes, present fair summaries of such federal statutes.

We have participated in the preparation of the Registration Statement, the Time of Sale Information and the Prospectus. From time to time, we have had discussions with officers, directors and employees of the Company, representatives of Deloitte & Touche LLP, the independent accountants who examined certain of the financial statements of the Company included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus and you and your representatives and your counsel concerning the information contained or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus. Based upon our participation and discussions described above, we are of the view that the Registration Statement, the Time of Sale Information and the Prospectus (except for the (1) financial statements, financial statement schedules and other financial and statistical data included or incorporated by reference therein and (2) information referred to in the Prospectus under the caption “Experts” as having been included or incorporated by reference in the Registration Statement and the Prospectus on the authority of Deloitte & Touche LLP, as experts, as to all of which we express no view) at the time the Registration Statement became effective under the Securities Act of 1933 (the “Act”) complied as to form in all material respects with the Act and the rules and regulations thereunder; the documents incorporated or deemed to be incorporated by reference into the Time of Sale Information and the Prospectus that were filed prior to the date of this opinion (except for the financial statements, financial statement schedules and other financial and statistical data included therein, as to all of which

[Insert Underwriters]

Re:		$[•] principal amount of Debt Securities, Series due [•],
		[•]% of Southwestern Public Service Company, a New Mexico corporation.

Ladies and Gentlemen:

This opinion is being furnished to you in connection with the issue and sale by Southwestern Public Service Company (the “Company”) of $[•] principal amount of Debt Securities, Series due [•], [•]% herein called the “Debt Securities”. This opinion is being delivered to you pursuant to Section 6(b) of the Underwriting Agreement, dated [•](the “Underwriting Agreement”), between the Company and the several underwriters named therein (the “Underwriters”). Unless otherwise stated, defined terms used herein shall have the respective meanings given them in the Underwriting Agreement.

We are familiar with the legal matters pertaining to, and the corporate proceedings of the Company taken with respect to, the authorization, issuance and sale by the Company of the Debt Securities. We have examined, among other things, the Registration Statement and the Prospectus, and any amendment or supplement thereto, the corporate records of the Company, the Indenture, the Supplemental Indenture creating the Debt Securities, the proceedings before The Public Regulation Commission of the State of New Mexico with respect to the issuance and sale of the Debt Securities and such other proceedings, papers and documents as we have deemed relevant for the purpose of rendering the opinions enumerated below. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as copies and the authenticity of all such latter documents. We have relied as to various questions of fact (but not as to legal conclusions) upon discussions with officers and representatives of the Company and the representations and warranties of the Company contained in the Underwriting Agreement and upon the certificates of public officials and of officers of the Company being delivered to you thereunder. With respect to the opinions expressed in paragraph (vi) below, we have relied on information obtained from public records and from the Company.

On the basis of the foregoing, and subject to the limitations and qualifications set forth herein, it is our opinion that:

1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of New Mexico with corporate power and authority to own or lease, as the case may be, and to operate its properties and conduct its business as described in the Prospectus and to enter into and perform its obligations under the Underwriting Agreement; and the Company is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to be so qualified would not have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiary taken as a whole, whether or not arising from transactions in the ordinary course of business;

2. The Indenture has been duly and validly authorized, executed and delivered by the Company and (assuming the Indenture has been duly authorized, executed and delivered by the Trustee) constitutes a legal and valid agreement of the Company, and does not violate New Mexico law;

3. The issuance and sale by the Company of the Debt Securities pursuant to the Underwriting Agreement have been duly authorized by all necessary corporate action;

B-1

4. The issuance and sale of the Debt Securities have been duly authorized and approved by an order of the New Mexico Public Regulation Commission and such order is final and in full force and effect on the date hereof, the time for appeal therefrom or review thereof or intervention with respect thereto having expired; no further approval, authorization, consent or other order of any public board or body (including the Public Utility Commission of Texas, the State Corporation Commission of Kansas and the Corporation Commission of Oklahoma) is required in connection with the transactions contemplated by the Underwriting Agreement or the Indenture, other than approvals that may be required under blue sky laws of any jurisdiction in connection with the purchase and distribution of the Debt Securities by the Underwriters in the manner contemplated herein and in the Prospectus;

5. The Underwriting Agreement has been duly authorized, executed and delivered by the Company;

6. With minor exceptions relating to the use of streets and highways outside incorporated communities in New Mexico, Oklahoma, and Texas and with respect to the right of the City of Pampa, Texas, to purchase properties of the Company within its limits at a purchase price to be determined upon appraisal, the Company holds valid franchises in the territory in which it operates which have no burdensome restrictions and are adequate to conduct its business in such territory;

7. Neither the execution and delivery of the Underwriting Agreement or the Supplemental Indenture, the issue and sale of the Debt Securities, nor the consummation of any other of the transactions therein contemplated, nor the fulfillment of the terms thereof will conflict with, result in a breach or violation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiary pursuant to, (i) the Restated Articles of Incorporation, as amended, or By-Laws; (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument known to us to which the Company or its subsidiary is a party or bound or to which its or their property is subject; or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company or its subsidiary of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or its subsidiary or any of its or their properties;

8. Other than as set forth in the Prospectus there is not pending or, to the best of our knowledge, threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any subsidiary is a party, or to which the property of the Company or its subsidiary thereof is subject, before or brought by any court or governmental agency or body, which individually or in the aggregate, would have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, or which might reasonably be expected to materially and adversely affect the consummation of the transactions contemplated in the Underwriting Agreement or the performance of its obligations thereunder or the transactions contemplated by the Prospectus;

In connection with this opinion, we have participated in discussions with officers and representatives of the Company, in certain of which your representatives and counsel also participated and at which the affairs of the Company and the contents of the Registration Statement, the Time of Sale Information and the Prospectus were discussed.

We are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information and the Prospectus. Subject to the foregoing, and to the other limitations and qualifications expressed in this letter, we may state that nothing has come to our attention that would lead us to believe that the Registration Statement, when it became effective, or at the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, the Time of Sale Information at the Time of Sale, as of , Time, on (being a time that you have informed us was prior to the sale of the Debt Securities by the Underwriters as contemplated by the Prospectus) contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or that, at the date the Prospectus Supplement was filed with the Securities and Exchange Commission, the Prospectus included, or, at the date hereof, the Prospectus

includes an untrue statement of a material fact or omitted, or omits, to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that we do not express any belief as to the financial statements (including the debt securities thereto) or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Time of Sale Information or the Prospectus, as to any information contained therein furnished to the Company in writing by any Underwriter expressly for use therein or as to the Statement of Eligibility.

This opinion is limited to the laws of the States of New Mexico, Texas, Kansas and Oklahoma and the federal law of the United States of America.
