Exhibit 99.01

Xcel Energy Inc.

Selected Unaudited Historical and Pro Forma Consolidated Condensed Financial Statements

     The unaudited historical and pro forma consolidated condensed financial statements presented are intended to show what our results of operations and financial position might have been had the acquisition by Xcel Energy of all the outstanding shares of NRG and the subsequent merger been completed at an earlier date. The unaudited actual and pro forma income statement data for the year ended Dec. 31, 2001 give effect to the offer and subsequent merger described above as if we had completed it as of Jan. 1, 2001. The unaudited pro forma balance sheet data gives effect to the offer and subsequent merger as if we had completed it on Dec. 31, 2001.

     The pro forma consolidated financial statements are presented for informational purposes only and do not purport to be indicative of the results of operations and financial position of Xcel Energy that would have been achieved if the offer and subsequent merger had been completed as of the dates indicated. In addition, the pro forma consolidated financial statements are not necessarily indicative of the results of operations or financial condition that may be achieved by us in the future. They also do not reflect the effect of any payment that may be required to be made in connection with the exercise of appraisal rights by NRG stockholders under Delaware law in connection with the subsequent merger.

Notes:

(1)	Assumes the payment of securities issuance costs, which will be reflected as a reduction in common equity (see Note 4).
(2)	We have allocated the excess of the aggregate purchase price to be paid for NRG’s shares over the 26% of the carrying value of NRG assets and liabilities to goodwill. Pursuant to Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets,” goodwill from acquisitions occurring after June 30, 2001 is not amortized. Accordingly, we have not provided for amortization expense of the excess of the aggregate purchase price to be paid for NRG’s shares over 26% of the carrying value of NRG’s assets and liabilities.
(3)	We have assumed elimination of the minority shareholders’ interest in income of NRG for the year ended Dec. 31, 2001. For approximately the first three months of the year, this interest was 18 percent of NRG shares; for the last 9 months, it was 26 percent.
(4)	We have assumed that we will exchange 24.7 million shares of Xcel Energy stock for all outstanding shares of NRG stock. However, due to differing levels of minority ownership during the year (see Note 3), we have calculated the share impact on a weighted average basis. Based on the exchange ratio, for approximately the first three months of 2001, only 15.7 million shares of Xcel Energy stock would have been required to reacquire the minority shares of NRG then outstanding.
