(1) On January 2, 2008, Mr. Ragan was issued 2,200 Restricted Stock Units ("RSU's") by NRG Energy, Inc. under NRG Energy, Inc.'s Long Term Incentive Plan (the "LTIP"). Each RSU is equivalent in value to one share of NRG's Common Stock, par value $0.01. On January 2, 2011, the RSUs vested. Pursuant to the LTIP, Mr. Ragan elected to satisfy his tax withholding obligation upon the exchange of common stock for RSU's by surrendering a number of shares of common stock having a value on the date of the exchange equal to the tax withholding obligation. This form is being filed to reflect the surrender of 675 shares of common stock to satisfy the grantee's tax withholding obligation.
(2) Represents Restricted Stock Units issued to Mr. Ragan by NRG Energy, Inc. under NRG Energy, Inc.'s Long Term Incentive Plan.
(3) Each Restricted Stock Unit is equivalent in value to one share of NRG Energy, Inc.'s Common Stock, par value $0.01 per share. Mr. Ragan will receive from NRG Energy, Inc. one such share of Common Stock for each Restricted Stock Unit on January 3, 2014.
(4) Includes 893 shares acquired under NRG Energy, Inc.'s Employee Stock Purchase Plan since the Reporting Person's last filing.
(5) Pursuant to the Grant Agreement by and between NRG Energy, Inc. and Mr. Ragan, the Stock Options will vest and become exercisable as follows: 33 1/3% on January 3, 2012; 33 1/3% on January 3, 2013; and, 33 1/3% on January 3, 2014.
(6) Stock Options expire ten years from the date of the grant.
(7) Mr. Ragan was issued 16,800 Performance Units by NRG under the LTIP on January 3, 2011.

The payout for each PU will be equal to a pro-rated amount in between one-half and one share of common stock if the Measurement Price equals or exceeds the Threshold Price but less than $26.66 (the "Target Price"). The payout for each PU will be equal to a pro-rated amount in between one and two shares of common stock if the Measurement Price is equal to the Target Price but less than $31.17 (the "Maximum Price"). The payout for each PU will be equal to two shares of common stock if the Measurement Price is equal to or greater than the Maximum Price.
