*	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 ("RSUs") issued to Reporting Person under NRG Energy, Inc.'s Amended and Restated Long Term Incentive Plan ("LTIP").
(2)	Each RSU is equivalent in value to one share of NRG's Common Stock, par value $.01 per share.
(3)	The Reporting Person will receive from NRG one such share of Common Stock for each RSU that will vest ratably over a three year period beginning on the first anniversary of the date of grant.
(4)	The Reporting Person was issued 19,740 Relative Performance Stock Units ("RPSUs") by NRG under the LTIP on January 3, 2017. The RPSUs will convert to shares of NRG Common Stock on January 3, 2020 only in the event the Company has achieved a certain level of total shareholder return ("TSR") relative to the Peer Group (defined below) over a three-year performance period. The number of shares of Common Stock that the Reporting Person may receive is interpolated for TSR falling between Threshold, Target, and Maximum levels as described below.
(5)	The Reporting Person will receive (i) a maximum of 39,480 shares of Common Stock if the Company's TSR is ranked at or above the 75th percentile relative to a peer group of companies approved by the Company's Compensation Committee (the "Peer Group") for the performance period (the "Maximum"); (ii) 19,740 shares of Common Stock if the Company's TSR is ranked at the 55th percentile relative to the Peer Group for the performance period (the "Target"); provided, however, if TSR is less than negative fifteen percent (-15%), the Company's TSR must be ranked at the 65th percentile relative to the Peer Group for the performance period to receive the Target award; or (iii) 4,935 shares of Common Stock if the Company's TSR is ranked at the 25th percentile relative to the Peer Group for the performance period (the "Threshold"). The Reporting Person will not receive any shares of Common Stock if the Company's TSR is below the 25th percentile relative to the Peer Group for the performance period.
