Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Gerald Luterman was appointed to the Board of Directors of NRG Energy, Inc., or NRG, effective April 24, 2009. Mr. Luterman joined the board as an independent director and was also appointed to serve on the Audit and Finance Committees of the Board of Directors. The Board has determined that Mr. Luterman qualifies as an "audit committee financial expert" within the meaning of the regulations of the U.S. Securities and Exchange Commission. There is no arrangement or understanding between Mr. Luterman and any other person pursuant to which he was appointed as a director.

Non-employee directors other than the Chairman, receive total annual compensation of $180,000 for their service as a member of the Board of Directors. Unless otherwise elected by the director, directors receive 50 percent of their total annual compensation in the form of cash and the remaining 50 percent in the form of vested deferred stock units, or DSU's. On April 24, 2009, Mr. Luterman received a grant of DSU's in an amount equal to $90,000 divided by the closing price of NRG's common stock on April 24, 2009. Each DSU is equivalent in value to one share of NRG's common stock. The DSU's issued to Mr. Luterman will be exchanged for such common stock on a one-to-one basis upon termination of his service on NRG's Board of Directors. The foregoing description of NRG's non-employee directors' compensation is qualified by reference to the description included in the preliminary proxy statement for NRG's 2009 Annual Meeting of Stockholders, which was filed with the Securities and Exchange Commission on April 2, 2009.

On April 27, 2009, NRG issued a press release announcing Mr. Luterman's appointment, a copy of which is attached as Exhibit 99.1 hereto and incorporated by reference.
