NRG Energy’s Board of Directors Rejects
Exelon Corporation’s Revised Unsolicited Proposal

PRINCETON, NJ; July 8, 2009—NRG Energy, Inc. (NYSE: NRG) today announced that its Board of Directors has unanimously determined that the July 2, 2009 revised unsolicited proposal from Exelon Corporation (NYSE: EXC) significantly undervalues NRG and is not in the best interests of NRG’s stockholders.

Accordingly, today, the following official response was sent to Exelon Chairman and CEO, John Rowe:

July 8, 2009

Mr. John W. Rowe
Chairman and CEO
Exelon Corporation
P.O. Box 805398
Chicago, IL 60680-5398

Dear Mr. Rowe:

The Board of Directors of NRG Energy, Inc., in consultation with its financial and legal advisors, has thoroughly reviewed and considered your revised offer, as detailed in your July 2^nd news release, which as of yesterday’s close represented $27 per NRG Share. The Board unanimously has rejected your proposal as it determined that the revised offer is not in the best interest of NRG stockholders in that it continues to substantially undervalue NRG. Indeed, by any objective analysis, the increase in your offer fails to adequately compensate NRG stockholders even for the value created by NRG since your original offer was launched. The Board also rejected this proposal due to the revised offer’s extraordinary conditionality which remains unchanged from Exelon’s original offer made last fall.

While your revised offer is not acceptable as is, it certainly represents a step in the right direction and is a welcome development after more than eight months of the 0.485 offer. The fact that you were able to increase your offer largely through over $200 million per year of newfound synergies identified by your consultants leaves open the possibility that, if you would properly recognize the value created by NRG itself, you would be able to increase your current 0.545 offer by a substantial amount.

To reiterate, these value creating actions by NRG include, but are not limited to, the following:

•	NRG’s Reliant Energy Acquisition—Worth $4.50 Per Share in Value:
	Your economists ascribed less than $1 per share to the value of Reliant Energy. You will note from NRG’s revised guidance for 2009, we expect Reliant’s adjusted earnings per share to approach $1 per NRG share just in the last eight months of 2009. Reliant Energy’s contribution to NRG’s adjusted EBITDA over the same period is expected to be over $400 million. The robust countercyclical earnings power of Reliant’s retail franchise is just one of several reasons why the Reliant acquisition is worth significantly more than $1 per NRG share. We are confident, based solely on the earnings guidance released today, that Exelon’s economists will see it the same way.
•	NRG’s Unique Position in Leading the Nuclear Renaissance:
	In your most recent investor presentation, you explicitly ascribe zero value to NRG’s nuclear development program. Yet Exelon has spent tens of millions of dollars over the past two years attempting to develop a greenfield nuclear plant in neighboring Victoria County. Surely Exelon, more than most, is in a position to appreciate and properly value our nuclear position in Texas, at the NRC and in the DOE loan guarantee program.
•	NRG’s Repowering Initiative Advances Low and No Carbon Technologies:

	Cedar Bayou unit 4, NRG’s new 550 megawatt combined cycle plant in ERCOT’s Houston Zone, our new wind farms, GenConn and eSolar are just the current lead projects in RepoweringNRG and are representative of low carbon, asset-based EBITDA growth of a kind that is absent from the Exelon portfolio.
•	NRG’s Significant Cost and Performance Improvements:
	Since 2005, NRG has executed on its FORNRG initiatives — NRG’s Companywide, multi-year initiative to increase the return on invested capital (ROIC) through operational performance improvements. This project has seen considerable success with over $150 million of after-tax savings through December 2008 and planned after-tax savings that we expect to result in approximately $300 million of annual additional recurring free cash flow improvements by 2012.

These value enhancing developments add to NRG’s financial strength which your revised offer does not yet appreciate or properly value. NRG is a Company that is on track to produce annual EBITDA for 2009 of $2.5 billion, which represents a compound annual growth rate in EBITDA over the past six years of 21% with a recurring free cash flow yield of 23%. It is the unanimously held view of NRG’s Board of Directors that such a company is worth significantly more than the $27 per share that your July 2^nd offer represents.

As we told you when we first met last September, NRG is open to any proposal that properly reflects NRG’s fundamental value and extraordinary growth prospects. If you wish to pursue a possible combination with NRG in a more cooperative fashion, you should increase your July 2^nd offer by an amount that properly reflects the specific value of the NRG initiatives, especially in light of the additional information provided today. Our management team then would be pleased to sit down with you or your economists and consultants to validate and quantify the combination synergies summarized in your July 2^nd presentation and to demonstrate further the full value of NRG’s exceptional operating franchise and its unique growth initiatives so that Exelon could provide a reasonable measure of that value to NRG’s stockholders.

Sincerely,

/s/ David Crane	/s/ Howard Cosgrove

President and Chief Executive Officer	Chairman of the Board
