CUSIP No. 629377508               SCHEDULE 13D


ITEM 3.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The   aggregate   purchase   price  for  the   14,025,000   Shares  was
approximately  $417,425,008.  The  Reporting  Persons  do not  directly  own any
Shares. The funds for the purchase the Shares reported in this Schedule 13D were
derived from margin account borrowings made in the ordinary course of business.

ITEM 4.        PURPOSE OF TRANSACTION.

         The Reporting Persons initially  reported this investment on a Schedule
13G filed on February 14, 2008.  The Reporting  Persons  initially  acquired the
Shares for investment in the ordinary  course of business  because they believed
the Shares presented an attractive investment opportunity. The Reporting Persons
decided to file this Schedule 13D to express  support for the  determination  by
the board of directors of the Company (the  "Board")  that the tender offer made
by Exelon  Corporation  and Exelon Xchange  Corporation  (the "Tender Offer") is
inadequate.

         On January 30, 2009, the Reporting Persons sent a letter (the "Letter")
to the Company  expressing their support for the determination by the Board that
the Tender  Offer is  inadequate  and to urge the Board to  evaluate  the Tender
Offer  on its  merits  and in  light  of the  expected  long-term  value  of the
Company's business. The Reporting Persons or their representatives may engage in
future discussions with management, the Board, other stockholders of the Company
and other relevant parties regarding the matters contained in the Letter, or any
other matters of interest to the Company's stockholders. A copy of the Letter is
attached hereto as Exhibit B and is incorporated herein by reference.

         Except as set forth herein or as would occur upon  completion of any of
the actions discussed herein, the Reporting Persons do not have any present plan
or proposal  that would relate to, or result in, any of the matters set forth in
subparagraphs  (a) - (j) of Item 4 of Schedule 13D. The Reporting Persons intend
to review their  investment in the Company on a continuing  basis and may engage
in discussions with management, the Board, other stockholders of the Company and
other relevant parties concerning the business, operations, management, strategy
and future plans of the Company. Depending on various factors including, without
limitation,  the  Company's  financial  position and  strategic  direction,  the
outcome of any discussions and actions  referenced  above,  actions taken by the
Board,  price  levels  of  the  Common  Stock,  other  investment  opportunities
available to the  Reporting  Persons,  conditions in the  securities  market and
general  economic  and industry  conditions,  the  Reporting  Persons may in the
future take such actions with respect to their investment in the Company as they
deem appropriate including, without limitation,  purchasing additional shares of
Common Stock, selling some or all of their Shares,  engaging in short selling of
or any  hedging  or similar  transactions  with  respect  to the  Shares  and/or
otherwise  changing their intention with respect to any and all matters referred
in Item 4 of Schedule 13D.

Howard Cosgrove
Chairman, Board of Directors
NRG Energy, Inc.
211 Carnegie Center
Princeton, New Jersey 08540


Dear Mr. Cosgrove:

               As  you  may  know,  Solus  Alternative  Asset  Management  LP is
investment adviser to Sola Ltd and Solus Core Opportunities Master Fund Ltd, two
funds  that are  longstanding  stockholders  of NRG  Energy,  Inc.  Like all NRG
shareholders, we have a vital interest in assuring that NRG's board of directors
(the "Board")  responds  appropriately  to the unsolicited  exchange offer being
made  by  Exelon  Corporation  ("Exelon").   After  careful  consideration,   we
unconditionally  agree with the Board's view that Exelon's  offer in its current
form  is  inadequate   because  it  is  highly   conditional  and  significantly
undervalues NRG.

               We are particularly concerned about Exelon's recent press release
claiming  that the tender of 45.6% of NRG's stock in  response  to the  exchange
offer "speaks powerfully to the merits of [its] proposed transaction . . . ." We
understand that a significant  number of NRG stockholders  also have substantial
holdings of Exelon - a matter not mentioned in Exelon's  release.  To the extent
that NRG holders who have  tendered into the current offer have more invested in
Exelon, their decision to tender may well represent a judgment that the offer is
favorable to EXELON rather than NRG.

               The Board should evaluate the exchange offer on its merits and in
light of the  expected  long-term  value of NRG's  business,  rather than on the
basis of  self-interested  arguments  concerning the significance of stockholder
reaction to the current  offer.  As I am sure you know,  under Delaware law, the
NRG Board must act in the  interests of ALL NRG  stockholders  but may take into
account  the fact that some  stockholders  have  goals  that  conflict  with the
interests  of other  stockholders.  SEE UNOCAL v. MESA,  493 A.2d 946, 955 (Del.
1985) (a board of directors in responding to a takeover bid may consider another
person's stock  ownership;  board's duty is to protect "the  corporation and its
owners from  perceived  harm whether a threat  originates  from third parties or
other shareholders.")

value and protect the interests of all NRG stockholders.
