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) On January 2, 2013 Mr. Hill was issued 13,500 Restricted Stock Units ("RSUs") by NRG Energy, Inc. under NRG's Long Term Incentive Plan ("LTIP"). Each RSU is equivalent in value to one share of NRG's Common Stock, par value $.01. On January 2, 2016, 13,500 shares vested. Mr. Hill elected to satisfy his tax obligation upon the exchange of common stock for RSUs having a value on the date of the exchange equal to the withholding obligation. This form is being filed to reflect the surrender of 5,722 shares of common stock to satisfy the grantee's tax withholding obligation.
(2) Reflects a reduction of 1,485 dividend equivalent rights ("DERs") that were forfeited upon the vesting of the Market Stock Units described in Table II, resulting in the reporting person holding 3,347 DERs in the aggregate. Dividend equivalent rights accrue on the reporting person's restricted stock units or market stock units, which become exercisable proportionately with the restricted stock units or market stock units to which they relate and may only be settled in NRG common stock. Each dividend equivalent right is the economic equivalent of one share of NRG common stock. Includes 164 shares acquired under NRG Energy, Inc.'s Employee Stock Purchase Plan since the Reporting Person's last filing.
(3) Mr. Hill was issued 22,800 Market Stock Units ("MSUs") by NRG under the LTIP on January 2, 2013 that vested on January 2, 2016. On the vesting date, he was entitled to receive a maximum of 45,600 shares of Common Stock if the Company has achieved a 100% increase in total shareholder return since the grant date (the "Maximum"); 22,800 shares of Common Stock if there is no change in total shareholder return since the grant date (the "Target"), or 11,400 shares of Common Stock if there is a 50% decrease in total shareholder return since the grant date (the "Threshold"). The number of shares of Common Stock that Mr. Hill may receive is interpolated for total shareholder return falling between Threshold, Target, and Maximum levels. On January 2, 2016, Mr. Hill did not receive any shares.
