     In connection with the issuance by CenterPoint Energy, Inc., a Texas corporation (the “Company”), of 25,300,000 shares (the “Shares”) of common stock, par value $0.01 per share, of the Company pursuant to (a) the Company’s Registration Statement on Form S-3 (Registration No. 333-153916) (the “Registration Statement”), which was filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), and (b) the related prospectus dated October 9, 2008, as supplemented by the prospectus supplement relating to the sale of the Shares dated June 9, 2010 (as so supplemented, the “Prospectus”), as filed by the Company with the Commission pursuant to Rule 424(b) under the Act, certain legal matters with respect to the Shares are being passed upon for you by us. At your request, this opinion is being furnished to you for filing as Exhibit 5.1 to the Company’s Current Report on Form 8-K to be filed with the Commission on the date hereof (the “Form 8-K”). The Shares are being offered, issued and sold pursuant to the Underwriting Agreement dated June 9, 2010 (the “Underwriting Agreement”) by and among the Company and J.P. Morgan Securities Inc., Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. Incorporated and Wells Fargo Securities, LLC, as representatives of the several Underwriters named in Schedule I thereto.

     In our capacity as your counsel in the connection referred to above, we have examined originals, or copies certified or otherwise identified, of (i) the Company’s Restated Articles of Incorporation and Amended and Restated Bylaws, in each case as amended to date; (ii) the Underwriting Agreement; (iii) the Registration Statement and the Prospectus; and (iv) corporate records of the Company as furnished to us by you, certificates of public officials and of representatives of the Company, statutes and other instruments and documents as a basis for the opinions hereinafter expressed. In giving such opinions, we have relied upon certificates of officers of the Company and of public officials with respect to the accuracy of the material factual matters contained in such certificates. In making our examination, we have assumed that the signatures on all documents examined by us are genuine, that all documents submitted to us as originals are accurate and complete, that all documents submitted to us as copies are true and correct copies of the originals thereof and that all information submitted to us was accurate and complete.

     On the basis of the foregoing, and subject to the assumptions, limitations and qualifications hereinafter set forth, we are of the opinion that the Shares have been duly authorized by all necessary corporate action on the part of the Company and, when issued and
