All Four Leading Proxy Advisory Firms Support NRG and Recommend NRG Stockholders Vote "FOR" All Four NRG Director Nominees on the White Proxy Card

Stockholders Recommended to Vote "Against" Exelon`s Board Expansion Proposal
PRINCETON, N.J.--(Business Wire)--
NRG Energy, Inc. (NYSE: NRG) today announced that RiskMetrics Group (formerly
Institutional Shareholder Services), PROXY Governance, Inc., Glass Lewis & Co.,
and Egan-Jones Proxy Services, the nation`s four leading proxy advisory firms,
recommend that their clients vote "FOR" the election of NRG`s highly qualified
and independent director nominees at NRG`s 2009 Annual Meeting of Stockholders
to be held on July 21. All of the proxy advisory firms also recommend that NRG
stockholders vote "AGAINST" Exelon`s Board expansion proposal.

"We are pleased that RiskMetrics, PROXY Governance, Glass Lewis, and Egan-Jones
all support the election of all four of NRG`s director nominees and are
unanimously opposed to expanding the NRG Board. While we appreciate the support
we`ve received from the proxy advisors, we very much appreciate that our
shareholders will be making their own decisions based on a variety of issues and
opinions," said David Crane, President and Chief Executive Officer of NRG.
"NRG`s current directors have overseen a five-year period of growth and value
creation and have contributed to what we believe is an unmatched record of
financial, operational and transactional execution during that time. Regardless
of the outcome with Exelon, our Board and management will remain committed, as
we always have been, to driving value for our stockholders and remaining open to
offers at the right price and on the right terms."

In its July 13, 2009, report, RiskMetrics (RMG) noted*:

* "Given RMG`s conclusion that Exelon`s current bid is not compelling enough to
support splitting the board with nine dissident nominees, RMG recommends that
shareholders vote on the Management Proxy (White Card), and support the
re-election of all the incumbent nominees." (emphasis added)
* "On balance, we conclude that Exelon`s current bid is not compelling enough
tosupport splitting the boardwith nine dissident nominees. Virtually all of the
NRG shareholders to whom we spoke expressed a belief that Exelon should sweeten
its offer." (emphasis added)
* "The downside to supporting Exelon at the annual meeting may be to embolden
Exelon and to undercut NRG`s negotiating leverage, with the net result a failure
to maximize value..." (emphasis added)
* "The nearly unanimous opinion of shareholders with whom we spoke was that the
NRG management team had done an exemplary job over recent years in creating
value." (emphasis added)

PROXY Governance in its July 9, 2009 report noted*:

* "As the incumbent board has demonstrated its commitment to shareholder value
not only through its willingness to engage Exelon in September 2008, but through
its ongoing initiatives to improve operating efficiencies, its willingness to
act on significant but short-fuse opportunities such as Reliant Retail, and its
long-term strategy to strengthen the company`s competitive stance in a
carbon-constrained economy, we believe shareholders will be best served by
re-electing the incumbent nominees." (emphasis added)
* "In September 2008, before the public tender offer and the proxy contest, NRG
voluntarily met with Exelon to begin exploring strategic options. By its own
account, NRG expected to continue those discussions at industry events in
November, in the hope financial markets would have begun to calm by then. The
clear implication is that, far from being entrenched, the company`s management
and board are open to strategic discussions which might maximize shareholder
value - and that the issue remains what it was last September, the question of
whether Exelon will pay full value for the company`s existing operations and
future potential." (emphasis added)
* "In NRG`s strategies over the past five years one sees an acute awareness of
opportunity, and a deep understanding of how and where to hedge various risks.
The opportunistic purchase of Reliant Retail - at 1.5x average adjusted EBITDA,
significantly below market valuations of 4.0x to 6.0x for similar assets -… is
the most recent case in point." (emphasis added)

Glass Lewis, in its July 9, 2009, report, stated the following*:

* "…We find no reason to recommend for the election of the Dissident [Exelon]
nominees to the NRG board of directors. In our opinion, the board and its
advisors have given Exelon`s proposals and Offer reasonable consideration."
(emphasis added)
* "… We note that the board has not closed itself off from future discussions
regarding a potential transaction with Exelon nor has it prohibited NRG
shareholders from tendering their shares to Exelon under the revised Offer.
Further, we note that the reelection of the incumbent director nominees does not
block Exelon`s revised Offer."
* "We also believe that the election of the Dissident [Exelon] nominees could
give Exelon an unnecessary advantage in a strategic transaction involving NRG.
In our opinion, the election of the incumbent nominees will help ensure that the
NRG board remains open to any, and all, potentially interested parties and
proposals." (emphasis added)
* "Given that we do not believe it is in the best interests of shareholders to
support Exelon`s nominees, we do not believe shareholders should support this
expansion in the Company`s board." (emphasis added)

Egan-Jones in its July 9, 2009 report stated*:

* "We believe, as reportedly so do several significant shareholders of the
Company, that Exelon`s revised offer of July 2 continues to undervalue the
Company, thereby making furtherance of its proxy contest undesirable at this
time."
* "We are of the view that the election of the Exelon nominees would not
contribute meaningfully to the quality of the Company`s board of directors."
* …"We believe that election of the slate of director nominees presented by the
management is in the best interest of Company and its shareholders."
* "We believe that approval of this proposal is not in the best interests of the
Company and its stockholders."

Crane concluded, "We strongly urge all NRG stockholders to vote "FOR" our
director nominees, in accordance with the recommendations of RiskMetrics, PROXY
Governance, Glass Lewis and Egan-Jones, on the WHITE proxy card, and "AGAINST"
Exelon`s proposal to expand the Company`s Board."
