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

Pastor Kirbyjon H. Caldwell was appointed to the Board of Directors of NRG Energy, Inc., or NRG, on March 23, 2009. Pastor Caldwell joined the board as an independent Class I director. There is no arrangement or understanding between Pastor Caldwell 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 March 23, 2009, Pastor Caldwell received a grant of DSU's in an amount equal to $90,000 divided by the closing price of NRG's common stock on March 23, 2009. Each DSU is equivalent in value to one share of NRG's common stock. The DSU's issued to Pastor Caldwell 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 definitive proxy statement for NRG's 2008 Annual Meeting of Stockholders, which was filed with the Securities and Exchange Commission on April 2, 2008.

On March 24, 2009, NRG issued a press release announcing Pastor Caldwell's appointment, a copy of which is attached as Exhibit 99.1 hereto and incorporated by reference.
