Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Represents Restricted Stock Units issued to Mr. Andrews under NRG Energy, Inc.'s Long Term Incentive Plan.
(2) Each RSU is equivalent in value to one share of NRG's Common Stock, par value $.01. Mr. Andrews will receive from NRG one such share of Common Stock, as follows: (i) 20,000 shares on September 6, 2012; (ii) 20,0000 shares on September 6, 2013; and (iii) 20,000 shares on September 6, 2014.
(3) Mr. Andrews was issued 60,000 Market Stock Units by NRG under the LTIP on September 6, 2011. The Market Stock Units will convert to shares of NRG Common Stock in one-third increments on each anniversary of the grant date beginning on September 6, 2012 and ending on September 6, 2014 only where the Company has achieved a certain level of total shareholder return. Total shareholder return will consist of the average of the closing price of NRG's Common Stock on each anniversary of the grant date and the nineteen preceding trading days and any dividends paid since the grant date as determined by the Compensation Committee.
(4) On each anniversary of the grant date, Mr. Andrews will receive a maximum of 40,000 shares of Common Stock if the Company has achieved a 100% increase in total shareholder return since the grant date (the "Maximum"); 20,000 shares of Common Stock if there is no change in total shareholder return since the grant date (the "Target"); or 10,000 shares of Common Stock if there is a 50% decrease in total shareholder return since the grant date (the "Threshold"). Mr. Andrews will not receive any shares of Common Stock if total shareholder return has decreased by more than 50% since the grant date. The number of shares of Common Stock that Mr. Andrews may receive is interpolated for total shareholder return falling between Threshold, Target, and Maximum levels.
