Explanation of Responses:

1. These transactions were previously reported on that certain Form 4 filed on January 6, 2015 (the "Original Filing"). The Original Filing is being amended to correct (a) the number of Restricted Stock Units in footnote 2 and (b) the number of derivative securities and the title and amount of underlying securities in Table II, columns 5 and 7.

2. On January 3, 2012, the Reporting Person was issued 2,600 Restricted Stock Units ("RSUs") by NRG 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 per share. On January 3, 2015 shares vested. The Reporting Person elected to satisfy his tax withholding 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 889 shares of common stock to satisfy the grantee's tax withholding obligation.

3. The acquisition of 461 shares of common stock reflects the net exercise of the Non-Qualified Stock Options with the remaining shares withheld by the Issuer to cover the exercise price and taxes associated with the automatic exercise.
