| Ratio                of earnings to combined fixed charges   and                preferred stock dividends (b)                                                                                                             |   |   | **2.9** |   |   |   | 2.6 |   |   |   | 2.7 |   |   |   | 2.6 |   |   |   | 1.9 |   |   |   | 1.7 |   |

| (a) |   | Net                income excludes minority interest, loss from discontinued operations                and                the cumulative effects of changes in accounting                principles.                                                                                        |

| (b) |   | PPL,                the parent holding company, does not have any preferred stock outstanding;                therefore, the ratio of earnings to combined fixed charges and preferred                stock dividends is the same as the ratio of earnings to fixed                charges. |
