          Tucson, Arizona  85701



          Ladies and Gentlemen:

                    We are acting as counsel to Tucson Electric Power
          Company, an Arizona corporation (the "Company"), in connection
          with the filing by the Company of a Registration Statement on
          Form S-3 (the "Registration Statement") under the Securities Act
          of 1933, as amended (the "Act"), relating to the registration of
          one million shares (the "Shares") of the Company's Common Stock,
          without par value ("Common Stock"), to be issued under its
          Investment Plus Plan (the "Plan").

                    For purposes of this opinion, we have examined
          originals or copies, certified or otherwise identified to our
          satisfaction, of (i) the Registration Statement, which
          incorporates the Plan in its entirety; (ii) the Amended and
          Restated Articles of Incorporation and Bylaws of the Company, as
          in effect on the date hereof; (iii) resolutions adopted by the
          Board of Directors of the Company relating to the adoption of the
          Plan and the reservation of Common Stock for issuance thereunder;
          and (iv) such other documents, certificates or other records as
          we have deemed necessary or appropriate.

                    Based upon the foregoing, and subject to the
          qualifications hereinafter expressed, we are of the opinion that:

                    (1)  The Company is a corporation duly organized,
                         validly existing and in good standing under the
                         laws of the State of Arizona;

                    (2)  With respect to outstanding shares of Common Stock
                         to be purchased in the open market for sale
                         pursuant to the Plan, when

                         (a)  the Registration Statement shall have become
                              effective under the Act, and

                         (b)  such shares of Common Stock shall have been
                              so purchased,

                         such Common Stock will have been legally and
                         validly issued and will be fully paid and
                         nonassessable; provided, however, that with
                         respect to Common Stock heretofore issued pursuant
                         to employee benefit plans and other offerings to
                         employees and/or shareholders, we have necessarily
                         assumed, without investigation, that the
                         certificates for such Common Stock have been duly
                         countersigned and registered by a transfer agent
                         and registrar and that, upon the issuance of such
                         Common Stock the Company received the full
                         consideration therefor authorized by the Company's
                         Board of Directors; and provided, further, that
                         this opinion does not extend to Common Stock,
                         issued subsequent to the date hereof, except as
                         contemplated in subparagraph (3) below; and

                    (3)  With respect to authorized but unissued Shares of
                         Common Stock to be issued and sold pursuant to the
                         Plan, when

                         (a)  the Registration Statement shall have become
                              effective under the Act,

                         (b)  the Company shall have received all necessary
                              regulatory approvals required for the
                              issuance and sale of the Shares in accordance
                              with the Plan,

                         (c)  the purchase price of the Shares shall have
                              been paid, and

                         (d)  the Shares shall have been issued in
                              accordance with the terms of the Plan,

                         such Common Stock will have been validly issued
                         and will be fully paid and nonassessable.

                    We are further of the opinion that the statements
          contained in the Prospectus portion of the Registration Statement
          under the caption "FEDERAL INCOME TAX INFORMATION" describing
          certain federal income tax consequences to holders of the Shares
          issued pursuant to the Plan, as qualified therein, constitutes an
          accurate description, in general terms, of the indicated United
          States Federal income tax consequences to holders of such Shares.

                    As members of the New York bar, we do not hold
          ourselves out as experts of the laws of other jurisdictions other
          than the laws of the United States and, to the extent the
          opinions expressed are dependent upon matters governed by the law
          of the State of Arizona, we have relied, with your consent, upon
          the opinion of even date herewith rendered to you by Dennis R.
          Nelson, Esq.

                    This letter is not being delivered for the benefit of,
          nor may it be relied upon by, the holders of Common Stock or any
          other party to which it is not specifically addressed or to which
          reliance has not been expressly permitted hereby.

                    We hereby consent to the filing of this opinion with
          the Securities and Exchange Commission as Exhibit 5(b) and 8 to
          the Registration Statement.


                                                  Very truly yours,

                                                  /s/ Reid & Priest LLP

                                                  REID & PRIEST LLP
