<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On December&nbsp;3, 2010, pursuant to an Agreement and Plan of Merger dated as of April&nbsp;11, 2010
(the &#147;Merger Agreement&#148;), RRI Energy Holdings, Inc., a wholly owned subsidiary of RRI Energy, Inc.,
merged with and into Mirant Corporation (&#147;Mirant&#148;), with Mirant continuing as the surviving entity
and a direct wholly-owned subsidiary of RRI Energy, Inc. (the &#147;Merger&#148;). Upon completion of the
Merger, RRI Energy, Inc. changed its corporate name to GenOn Energy, Inc. (&#147;GenOn Energy&#148; or the
&#147;Registrant&#148;). Pursuant to the Merger Agreement, each outstanding option issued under the Mirant
Corporation 2005 Omnibus Incentive Compensation Plan (the &#147;Mirant Legacy Plan&#148;) to purchase common
stock of Mirant Corporation was converted to a fully exercisable option to purchase the number of
shares of the Registrant&#146;s common stock, par value $0.001 per share (&#147;Common Stock&#148;) obtained by
multiplying the number of Mirant shares subject to the option by the 2.835 exchange ratio set forth
in the Merger Agreement. This Registration Statement on Form S-8 is filed by the Registrant for
the purpose of registering 66,111,053 shares of Common Stock issuable pursuant to (a)&nbsp;awards
assumed by the Registrant granted under the Mirant Legacy Plan, (b)&nbsp;awards granted under the GenOn
Energy, Inc. 2002 Long-Term Incentive Plan, the GenOn Energy, Inc. 2002 Stock Plan, the Long-Term
Incentive Plan of GenOn Energy, Inc. and the GenOn Energy, Inc. Transition Stock Plan

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">(b)&nbsp;The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant&#146;s annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">(h)&nbsp;Insofar as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Securities Act of 1933, and is, therefore unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Registrant of expenses
incurred by a director, officer or controlling person of the Registrant in the successful defense
of any action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final adjudication of such
issue.

EXPLANATORY STATEMENT
On December 3, 2010, pursuant to an Agreement and Plan of Merger dated as of April 11, 2010
(the "Merger Agreement"), RRI Energy Holdings, Inc., a wholly owned subsidiary of RRI Energy, Inc.,
merged with and into Mirant Corporation ("Mirant"), with Mirant continuing as the surviving entity
and a direct wholly-owned subsidiary of RRI Energy, Inc. (the "Merger"). Upon completion of the
Merger, RRI Energy, Inc. changed its corporate name to GenOn Energy, Inc. ("GenOn Energy" or the
"Registrant"). Pursuant to the Merger Agreement, each outstanding option issued under the Mirant
Corporation 2005 Omnibus Incentive Compensation Plan (the "Mirant Legacy Plan") to purchase common
stock of Mirant Corporation was converted to a fully exercisable option to purchase the number of
shares of the Registrant's common stock, par value $0.001 per share ("Common Stock") obtained by
multiplying the number of Mirant shares subject to the option by the 2.835 exchange ratio set forth
in the Merger Agreement. This Registration Statement on Form S-8 is filed by the Registrant for
the purpose of registering 66,111,053 shares of Common Stock issuable pursuant to (a) awards
assumed by the Registrant granted under the Mirant Legacy Plan, (b) awards granted under the GenOn
Energy, Inc. 2002 Long-Term Incentive Plan, the GenOn Energy, Inc. 2002 Stock Plan, the Long-Term
Incentive Plan of GenOn Energy, Inc. and the GenOn Energy, Inc. Transition Stock Plan
(collectively, the "RRI Legacy Plans") and (c) awards granted following the Merger under the GenOn
Energy, Inc. 2010 Omnibus Incentive Plan (the "GenOn Plan").

Not applicable.
Item 5. Interests of Named Experts and Counsel.
The validity of the shares offered hereby is being passed upon for the Registrant by Michael
L. Jines, Executive Vice President, General Counsel and Corporate Secretary and Chief Compliance
Officer of the Registrant. Mr. Jines is eligible to participate in the GenOn Plan. In addition,
as of December 3, 2010, Mr. Jines owned 158,774 shares of Common Stock, as reduced by such number

restricted stock units on December 3, 2010, and held options, which were granted under the RRI
Legacy Plans, to purchase 442,416 shares of Common Stock.
Item 6. Indemnification of Directors and Officers.
Under the Delaware General Corporation Law, which is referred to as the DGCL, a Delaware
corporation must indemnify its present or former directors and officers against expenses (including
attorneys' fees) actually and reasonably incurred to the extent that the officer or director has
been successful on the merits or otherwise in defense of any action, suit or proceeding brought
against him or her by reason of the fact that he or she is or was a director or officer of the
corporation.
The DGCL generally permits a Delaware corporation to indemnify directors and officers against
expenses, judgments, fines and amounts paid in settlement of any action or suit for actions taken
in good faith and in a manner they reasonably believed to be in, or not opposed to, the best
interests of the corporation and, with respect to any criminal action, which they had no reasonable
cause to believe was unlawful.
The Registrant's bylaws provide that it will, to the fullest extent permitted by law,
indemnify and hold its directors and officers harmless from and against any and all losses,
liabilities, claims, damages and expenses arising out of any event or occurrence related to the
fact that such person is or was a director or officer of the Registrant or is or was serving as a
director, officer, employee, agent or fiduciary of the Registrant or of any other corporation,
partnership, limited liability company, association, joint venture, trust, employee benefit plan or
other enterprise that such person is or was serving at the request of the Registrant.
The DGCL and the Registrant's bylaws permit the Registrant to maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the Registrant or
another corporation, partnership, joint venture, trust or other enterprise against any such
expense, liability or loss, whether or not the Registrant would have the power to indemnify such
person against such expense, liability or loss under applicable law.

Item 9. Undertakings
.
The undersigned Registrant hereby undertakes:
(a) (1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the
Registration Statement (or the most recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities
offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the
effective registration statement; and
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to such information in
the Registration Statement;
provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration
Statement is on Form S-8, and the information required to be included in a post-effective amendment
by those paragraphs is contained in reports filed with or furnished to the Commission by the
Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933,
each such post-effective amendment shall be deemed to be a new registration statement relating to
the securities offered herein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof.
(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Securities Act of 1933, and is, therefore unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Registrant of expenses
incurred by a director, officer or controlling person of the Registrant in the successful defense
