Re: Registration Statement on FormS-1
Ladies and Gentlemen:
We have acted as counsel to Tucson Electric Power Company, an Arizona corporation (the “Company”), in connection with the preparation of a registration statement on FormS-1 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), to be filed with the Securities and Exchange Commission (the “SEC”) on or about the date hereof. The Registration Statement relates to the proposed offering and sale of the Company’s Senior Notes (the “Securities”). The Securities will be issued under an indenture, dated as of November 1, 2011, between the Company and U.S. Bank National Association, as trustee (the “Trustee”), and the officer’s certificate, supplementing the indenture and establishing the terms of the Securities (the indenture and officer’s certificate are collectively referred to herein as the “Indenture”).
In connection with this opinion letter, we have examined originals, or copies certified or otherwise identified to our satisfaction, of (i) the Restated Articles of Incorporation of the Company, as amended, and the Bylaws of the Company, as amended, (ii) certain resolutions of the Company’s Board of Directors relating to the Registration Statement and the Securities, (iii) the Registration Statement and the prospectus included therein, (iv) the Indenture, and (v) such other instruments, certificates, records, and documents, and such matters of law, as we have considered necessary or appropriate for the purposes hereof. 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 the originals of such latter documents. As to any facts material to our opinion, we have, when relevant facts were not independently established, relied upon the Registration Statement, resolutions, instruments, certificates, records, and documents.
We have assumed for purposes of the opinion expressed below, without any independent investigation or verification of any kind, the due authorization, execution and delivery of the Indenture by the Trustee, the due authentication of the Securities by the Trustee; the legal right and power under all applicable laws and regulations of the Trustee to execute, deliver and perform its obligations under the Indenture; the validity, binding effect and enforceability against the Trustee in accordance with the terms of the Indenture; and that such Securities shall have been issued in compliance with an appropriate order of the Arizona Corporation Commission.
