ITEM 2.02.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

On May 9, 2007, TXU Corp. (the "Company") issued a press release announcing its
financial results for the first quarter ended March 31, 2007, and distributed
its 2007 first quarter Earnings Supplement. Such press release is furnished
herewith as Exhibit 99.1, and such Earnings Supplement is furnished herewith as
Exhibit 99.2.

Within the press release and the supplemental financial information furnished
herewith, the Company makes reference to certain financial measures that are not
prepared in accordance with accounting principles generally accepted in the
United States ("GAAP"), more fully explained in the press release. The Company
believes that such non-GAAP measures represent important internal measures of
performance. Accordingly, where these non-GAAP measures are provided, it is done
so that investors have the same financial data that management uses with the
belief that it will assist the investment community in properly assessing the
underlying performance of the Company on a year-over-year basis. Whenever such
information is presented, the Company has complied with the provisions of the
rules of Regulation G and Item 2.02 of Form 8-K under the Securities Exchange
Act of 1934.
