Re:		Registration Statement on Form S-3 (Registration No. 333-130549)

Ladies and Gentlemen:

We are issuing this opinion letter in our capacity as special legal counsel to NRG Energy, Inc., a Delaware corporation (the “Issuer”), and the guarantors set forth on Exhibit A hereto (the “Guarantors” and, collectively with the Issuer, the “Registrants”). This opinion letter is being delivered in connection with the issuance and sale by the Issuer of $1,100,000,000 in aggregate principal amount of the Issuer’s 7.375% Senior Notes due 2017 (the “Notes”) pursuant to a Registration Statement on Form S-3 (Registration No. 333-130549) as filed with the Securities and Exchange Commission (the “Commission”) on December 21, 2005, under the Securities Act of 1933, as amended (the “Act”) (such Registration Statement, as amended or supplemented, is hereinafter referred to as the “Registration Statement”).

The obligations of the Issuer under the Notes will be guaranteed by, among others, the Guarantors (the “Guarantees”). The Notes are to be issued pursuant to the Indenture (the “Base Indenture”), dated as of February 2, 2006, among the Issuer and Law Debenture Trust Company of New York, as trustee (the “Trustee”), as supplemented by the Ninth Supplemental Indenture, dated as of November 21, 2006, among the issuer, the Guarantors, certain other guarantors named therein and the Trustee (the “Ninth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). Pursuant to the Indenture, the Guarantors, along with other guarantors, will guarantee the obligations of the Issuer under the Notes.

In connection with issuing this opinion letter, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including (i) resolutions of the Registrants with respect to the issuance of the Notes and the Guarantees, (ii) organizational documents of the Registrants, (iii) the Indenture and (iv) the Registration Statement.

For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the genuineness of the signatures of persons signing all documents in connection

with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto and the due authorization, execution and delivery of all documents by the parties thereto. As to any facts material to the opinions expressed herein which we have not independently established or verified, we have relied upon statements and representations of officers and other representatives of the Registrants and others.

Our opinion expressed below is subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of (i) any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar law affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law) and (iii) public policy considerations which may limit the rights of parties to obtain certain remedies.

Based upon and subject to the assumptions, qualifications, exclusions and limitations and the further limitations set forth below, we are of the opinion that when the Notes have been duly executed and authenticated in accordance with the provisions of the Indenture, the Notes will be binding obligations of the Issuer and the Guarantees will be binding obligations of the Guarantors.

We hereby consent to the filing of this opinion with the Commission to be incorporated by reference into the Registration Statement. We also consent to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

This opinion is furnished to you in connection with the issuance and sale of the Notes and is not to be used, circulated, quoted or otherwise relied upon for any other purpose.
