all as contemplated by the Registration Statement on Form S-3 (the “Registration Statement”) proposed to be filed by the Registrants with the Securities and Exchange Commission (“Commission”) on or about the date hereof for the registration of the Securities under the Securities Act of 1933, as amended (the “Act”), and for the

qualification under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”) of the PPL Capital Indenture, the PPL Capital Subordinated Indenture, the PPL Electric Indenture, the LKE Indenture, the LG&E Indenture and the KU Indenture.

We have reviewed the Registration Statement and such other agreements, documents, records, certificates and other materials, and have reviewed and are familiar with such corporate proceedings and satisfied ourselves as to such other matters, as we have considered relevant or necessary as a basis for this opinion. In such review, we have assumed the accuracy and completeness of all agreements, documents, records, certificates and other materials submitted to us, the conformity with the originals of all such materials submitted to us as copies (whether or not certified and including facsimiles), the authenticity of the originals of such materials and all materials submitted to us as originals, the genuineness of all signatures and the legal capacity of all natural persons.

For purposes of this opinion letter, we have assumed that, at the time of issuance and sale of any Securities (i) the Registration Statement, as it may be amended, shall have become effective under the Act and such effectiveness shall not have been terminated or withdrawn; (ii) one or more supplements to the prospectus which describe such Securities and specify certain pricing and issuance terms of such Securities shall have been filed with the Commission pursuant to Rule 424(b) under the Act; (iii) the indenture pursuant to which such debt Securities are to be issued shall have been qualified under the Trust Indenture Act and shall constitute the valid and legally binding obligation of the trustee thereunder; (iv) the Registrant issuing such Securities (a) is duly organized, validly existing and in good standing under the law of its jurisdiction of organization, and (b) has the power to execute and deliver, and perform its obligations under, the Securities and the indenture pursuant to which such Securities are issued; (v) the board of directors or managers of the Registrant or Registrants issuing such Securities, or a duly authorized committee thereof, and/or the proper officers of such Registrant or Registrants acting pursuant to properly delegated authority (any of the foregoing, a “Board”), shall have taken such action as may be necessary to authorize the indentures, the issuance and sale of such Securities and, if applicable, to establish the relative rights and preferences of such Securities, or other terms of such Securities, in each case as set forth in or contemplated by the Registration Statement and any prospectus supplement relating to such Securities, and shall not have rescinded any such action; (vi) there shall not have occurred any change in law or any authorization affecting the legality or enforceability of such Securities; and (vii) each Registrant issuing such Securities shall remain duly organized and validly existing under the laws of the jurisdiction or jurisdictions of incorporation or other organization in which it is incorporated or otherwise organized on the date hereof. We have also assumed that neither the establishment of any terms of any Security to be established subsequent to the date hereof, nor the issuance and delivery of such Security, nor the compliance by the Registrant issuing such Security with the terms

thereof will (a) violate any law (other than the Applicable Law (as defined below)) or (b) require any authorization, consent, order, approval or license (or the like) of, or any exemption (or the like) from, or any registration or filing with, or any report or notice to, any executive, legislative, judicial, administrative or regulatory body (a “Governmental Approval”) except for any Utility Commission Approvals (as defined below) as shall have been obtained and be in full force and effect and sufficient to authorize such Securities, or (c) violate or conflict with, result in a breach of, or constitute a default under, (i) the articles or certificate of incorporation or formation, as applicable, or by-laws or limited liability company operating agreement, as applicable, of the issuer or any other agreement or instrument to which the issuer or any of its affiliates is a party or by which the issuer or any of its affiliates or any of their respective properties may be bound, (ii) any Governmental Approval (including any Utility Commission Approval) that may be applicable to the Company or any of its affiliates or any of their respective properties or (iii) any order, decision, judgment or decree that may be applicable to the issuer or any of its affiliates or any of their respective properties.

We note that prior to the issuance of PPL Electric Debt Securities, LG&E Debt Securities and KU Debt Securities, approvals of the Pennsylvania Public Utility Commission (in the case of PPL Electric), the Kentucky Public Service Commission (in the case of LG&E and KU) and the Virginia State Corporation Commission and the Tennessee Public Utility Commission (in the case of KU), and/or the Federal Energy Regulatory Commission (in the case of PPL Electric, LG&E and KU) may be required to authorize such issuance (any of the foregoing commissions, the “Utility Commissions,” and any of the foregoing such approvals, “Utility Commission Approvals”).

On the basis of the assumptions and subject to the qualifications and limitations set forth herein, we are of the opinion that
