Exhibit 99.1

NRG Energy, Inc. Responds to Exelon Regulatory Filings

PRINCETON, N.J. – December 18, 2008 – NRG Energy, Inc. (NYSE:NRG) today issued the following statement in response to Exelon Corporation’s filings for regulatory approval with the Federal Energy Regulatory Commission (FERC), the Department of Justice and the Federal Trade Commission:

Exelon’s attempt to secure regulatory approvals is premature because there is no transaction to approve. Exelon’s filings are an unnecessary distraction for regulators at this time given the uncertainty of completing the transaction. Processing the filings would result in an inefficient use of government resources.

In addition, there are a number of hurdles that would need to be overcome for these approvals to be granted. The Department of Justice or Federal Trade Commission will review the proposed takeover to determine if it impedes competition in the relevant energy markets. Given the size and complexity of the deal, Exelon should not receive early termination of its requested pre-merger review. For FERC to approve this transaction, the agency must conclude that the transaction is in the public interest and that it will not increase market concentration, adversely impact competition, or raise rates. The transaction is also subject to a number of other regulatory approvals and filings, including: the Nuclear Regulatory Commission and the state public utility commissions of California, Illinois, New York, Pennsylvania and Texas.

More importantly, Exelon’s offer continues to significantly undervalue NRG and is not in the best interests of NRG or its stockholders. As a result, NRG’s Board of Directors voted unanimously on November 24, 2008, to reject Exelon’s unsolicited proposal and recommended to its stockholders not to tender their shares. The regulatory filings by Exelon do nothing to address this fundamental issue.
