Summary of NRG ENERGY, INC.

Item 5.05 Amendments to the Registrant's Code of Ethics, or Waiver of a Provision of the Code of Ethics.

On July 1, 2009, the Board of Directors (the "Board") of NRG Energy, Inc. ("NRG") approved and adopted an amended Code of Conduct. The "Confidentiality" section of the Code of Conduct was amended to clarify that directors of NRG shall not disclose NRG's confidential information to any third party without the specific authorization of a majority of the entire Board. In the event of noncompliance by any director with this confidentiality obligation, the Board shall determine the appropriate consequences in its reasonable, good faith judgment by a resolution of a majority of the entire Board, which consequences may include termination of membership on Board committees, forfeiture of director compensation and, after August 1, 2009, if a court of competent jurisdiction determines that the breach of the director's confidentiality obligation constitutes a breach of the duty of loyalty, NRG may apply to the Delaware Chancery Court to have the director removed in accordance with the Delaware General Corporation Law.

The description above is qualified in its entirety by reference to the amended Code of Conduct, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
