Ladies and Gentlemen:

We have acted as counsel for CenterPoint Energy Restoration Bond Company, LLC, a Delaware limited liability company (the “Company”), in connection with the preparation of the Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company and CenterPoint Energy Houston Electric, LLC, a Texas limited liability company (“CenterPoint Houston”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, on October 6, 2009 relating to the proposed issuance of system restoration bonds of the Company (the “System Restoration Bonds”) to be offered as described in the form of the prospectus supplement (the “Prospectus Supplement”) and the prospectus (the “Prospectus”) included as part of the Registration Statement and in connection with the matters set forth herein. Capitalized terms used in this letter and not defined herein have the meanings given to such terms in the Prospectus Supplement and Prospectus. At your request, this opinion is being furnished to you for filing as Exhibit 5.1 to the Registration Statement.

In our capacity as your counsel, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein, including:
