NRG Comments on Exelon’s Proposal to Expand
NRG’s Board of Directors and its Slate of Nine Director Nominees

PRINCETON, NJ; January 30, 2009 – NRG Energy, Inc. (NYSE: NRG) confirmed today that Exelon Corporation (NYSE: EXC) has submitted to NRG a stockholder proposal to expand the size of the NRG Board of Directors and a slate of nine director nominees for election at NRG’s 2009 Annual Meeting of Stockholders. If Exelon’s proposal to expand the size of the NRG Board of Directors were approved by NRG’s stockholders and all of Exelon’s nominees were elected to the Board, Exelon’s nominees would constitute nearly 50% of the Board. The Governance and Nominating Committee of NRG’s Board of Directors will review Exelon’s proposal to expand the size of the Board and its slate of director nominees.

In the meantime, NRG commented on today’s developments saying, “The Company believes Exelon’s actions to initiate a proxy fight are a clear attempt to compromise the independence of NRG’s Board in order to force a sale of NRG to Exelon at a price that is highly dilutive to NRG stockholders on a free cash flow basis. Through this latest aggressive tactic, Exelon is attempting to dilute NRG’s Board of Directors and NRG stockholder value, while attempting to take all the value for Exelon’s stockholders.”

The NRG Board and management, after careful and impartial consideration, concluded that Exelon’s current offer is not only inadequate, but also is dilutive, significantly undervalues NRG, and does not fully reflect the underlying fundamental value of NRG’s assets, operations and strategic plan, including its strong market position and future growth prospects. The Board also noted, in regards to Exelon’s unsolicited exchange offer, the lack of any committed financing to complete the offer and the many unfulfilled conditions—including regulatory and Exelon stockholder approvals, among others.

NRG continues to believe that allowing Exelon to conduct due diligence is premature given that the offer price remains unchanged and, as Exelon has stated, is unlikely to increase materially. As previously announced, NRG is currently engaged in market discovery to determine the greatest value option available for NRG stockholders and has indicated to Exelon that, at some point, Exelon might be allowed to conduct due diligence as part of this broader process.

Exelon’s hand-picked nominees, if elected, would be required to exercise their fiduciary duties properly on behalf of all NRG stockholders. However, NRG questions the independence of Exelon’s slate and is concerned that, if elected to the NRG Board, Exelon’s nominees would have inherent conflicts of interest in evaluating any transaction between NRG and Exelon or any alternative transaction.

NRG’s current Board of Directors consists of highly qualified, proven leaders and business professionals with considerable combined experience overseeing a competitive power generation company and individual experience in the diverse disciplines important to NRG’s business. The NRG Board already is truly independent, with a non-executive Chairman and only one Director who is also a member of management, NRG’s CEO. Given their qualifications, their experience and their independence, the NRG Board of Directors, as presently constituted, is best positioned to act on behalf of all NRG stockholders.
