PPL Corporation
Two North Ninth Street
Allentown, Pennsylvania 18101

Ladies and Gentlemen:

          I am Senior Counsel of PPL Services Corporation, a subsidiary of PPL
Corporation, a corporation organized under the laws of the Commonwealth of
Pennsylvania (the "Company"), and, as such, am familiar with the affairs of
the Company.

          With respect to the Registration Statement on Form S-8 (the
"Registration Statement") to be filed by the Company on or about the date
hereof with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "Act"), in connection with the registration by the
Company of 6,500,000 shares of its Common Stock (the "Shares"), par value
$0.01 per share, to be issued from time to time in connection with awards made
by the Company under its Incentive Compensation Plan and Incentive
Compensation Plan for Key Employees (the "Plans"), I wish to advise you as
follows:

          I am of the opinion that the Company is a corporation validly
organized and existing under the laws of the Commonwealth of Pennsylvania and
is duly qualified to carry on the business which it is now conducting in that
Commonwealth.



          I am further of the opinion that the Shares will be legally issued,
fully paid and nonassessable when they have been issued in accordance with the
Plans.

          I hereby consent to the use of this opinion as an exhibit to said
Registration Statement. I also hereby give my consent to the use of my name in
the opinion of Simpson Thacher & Bartlett LLP, filed as Exhibit 5(b) to said
Registration Statement.

                                                     Very truly yours,



                                                     /s/ Thomas D. Salus
