Explanation of Responses:

1. Includes 19,834 Restricted Stock Units ("RSUs") issued to Ms. Dehne by NRG Energy, Inc. under NRG's Long Term Incentive Plan ("LTIP") and 948 dividend equivalent rights ("DERs"). Each RSU is equivalent in value to one share of NRG's Common Stock, par value $.01. Upon vesting of the RSUs, Ms. Dehne will receive from NRG the following: (i) 6,900 shares issued on January 3, 2015; (ii) 6,800 shares issued on January 2, 2016; (iii) 6,134 shares issued on January 2, 2017. Each DER will accrue on Ms. Dehne's RSUs or MSUs and will become exercisable proportionately with the RSUs or MSUs to which they relate and can only be settled in NRG common stock. Each DER is the economic equivalent to one share of NRG common stock.

2. Ms. Dehne was issued 11,500 Market Stock Units ("MSUs") by NRG under the LTIP on January 3, 2012. The MSUs will convert to shares of NRG Common Stock on January 3, 2015 only in the event the Company has achieved a certain level of total shareholder return ("TSR"). TSR will consist of the average of the closing price of NRG's Common Stock on January 3, 2015 and the nineteen preceding trading days and any dividends paid since the grant date as determined by the Compensation Committee.

3. Ms. Dehne will receive a maximum of 23,000 shares of Common Stock if the Company has achieved a 100% increase in TSR since the grant date (the "Maximum"); 11,500 shares of Common Stock if there is no change in TSR since the grant date (the "Target"); or 5,750 shares of Common Stock if there is a 50% decrease in TSR since the grant date (the "Threshold"). Ms. Dehne will not receive any shares of Common Stock if TSR has decreased by more than 50% since the grant date. The number of shares of Common Stock that Ms. Dehne may receive is interpolated for TSR falling between Threshold, Target, and Maximum levels.
