NRG Energy Believes Exelon’s Weak Tender Results Show Significant
Deterioration in Overall Support for Exelon Exchange Offer; NRG
Continues to Create Value That Outweighs Exelon’s Proposal

PRINCETON, NJ; June 17, 2009—NRG Energy, Inc. (NYSE: NRG) today commented on the preliminary tender offer results announced by Exelon Corporation’s (NYSE: EXC). Today Exelon announced that 12% of NRG shares tendered into the Exelon offer as of June 16, 2009, as compared with 51% tendered on February 26, 2009.

Today’s results show a marked deterioration in overall support for the Exelon exchange offer by NRG stockholders and Exelon’s decision to extend its exchange offer ahead of its scheduled expiration is recognition of this. NRG believes the low number of shares tendered reflects the understanding of NRG stockholders that the value NRG has created over the past eight months greatly outweighs the value of Exelon’s proposal.

Based on yesterday’s closing price for both stocks, Exelon’s offer represents a premium of only 3.6% to NRG stockholders. NRG believes this exchange offer result is a clear and convincing message to Exelon that a strong majority of NRG’s stockholders believe that Exelon’s proposal is not in their best interests. NRG continues to view Exelon’s highly conditional proposal as inadequate due to a number of factors, including its dilution of NRG stockholders’ cash contribution, lack of premium or committed financing, and deterioration in Exelon’s prospects.

NRG has and will continue to focus on executing its strategic initiatives and building upon its track record of delivering strong returns for its stockholders. NRG annual meeting of stockholders is scheduled for July 21, 2009. The NRG Board of Directors recommends stockholders re-elect its four experienced and highly qualified independent directors and support the Board’s ongoing efforts to create additional value by voting the WHITE proxy card sent to stockholders this week. NRG also asks that stockholders disregard any blue proxy card sent by Exelon Corporation and vote against Exelon’s proposal to expand the NRG Board.
