limited liability company and Salton Sea Power L.L.C., a Delaware limited
liability company (the foregoing collectively, other than the Funding
Corporation, the "Guarantors"), have requested our opinion in connection with
various legal matters relating to the filing of a Registration Statement on Form
S-4 (File No. 333-79581) (the "Registration Statement"), under the Securities
Act of 1933, as amended, covering the offer to exchange 7.475% Senior Secured
Series F Bonds Due November 30, 2018 ("New Securities"), for an equal principal
amount of outstanding 7.475% Senior Secured Series F Bonds Due November 30, 2018
("Old Securities"), of which $285,000,000 principal amount is outstanding. The
Old Securities were, and the New Securities are to be, issued under the Trust
Indenture, dated as of July 21, 1995, as supplemented and amended by the First
Supplemental Indenture dated as of October 18, 1995, the Second Supplemental
Indenture dated as of June 20, 1996, the Third Supplemental Indenture, dated as
of July 29, 1996, the Fourth Supplemental Indenture, dated as of October 13,
1998, the Fifth Supplemental Indenture, dated as of February 16, 1999 (as so
supplemented and amended, the "Indenture"), and the Sixth Supplemental
Indenture, dated as of the date hereof (the "Sixth Supplemental Indenture"),
each by and between the Funding Corporation and Chase Manhattan Bank and Trust
Company National Association (as successor in interest to Chemical Trust Company
of California), as trustee (the "Trustee"). The exchange will be made pursuant
to an exchange offer (the "Exchange Offer") contemplated by the Registration
Statement.

     We have examined copies of such records of the Funding Corporation and the
Guarantors and such other certificates and documents as we have deemed relevant
and necessary for the opinions hereinafter set forth. In such examination, we
have assumed the genuineness of all signatures, and the authenticity of all
documents submitted to us as originals and the conformity to authentic originals
of all documents submitted to us as certified or reproduced copies. We have also
assumed the legal capacity of all persons executing such documents and the truth
and correctness of any representations or warranties therein contained. As to
various questions of fact material to such opinions, we have relied upon
certificates of officers of the Funding Corporation and the Guarantors and of
public officials.

     Based upon the foregoing, we are of the opinion that:

1.  The Funding Corporation, Fish Lake Power LLC, CalEnergy Operating Company,
    VPC Geothermal LLC, CE Turbo LLC, CE Salton Sea Inc., Salton Sea Minerals
    Corp., CalEnergy Minerals LLC, Salton Sea Power L.L.C. and Salton Sea
    Royalty LLC are duly formed

    and validly existing under the laws of the State of Delaware.

2.  The execution and delivery of the Indenture and the Sixth Supplemental
    Indenture have been duly authorized by the Funding Corporation and the
    Guarantors, and the Indenture and the Sixth Supplemental Indenture together
    constitute a valid and binding obligation of the Funding Corporation and the
    Guarantors, enforceable against the Funding Corporation and the Guarantors
    in accordance with the terms thereof, except as enforcement thereof may be
    limited by bankruptcy, insolvency, reorganization, fraudulent conveyance and
    other similar laws affecting the enforcement of creditors' rights generally
    and except as enforcement thereof is subject to general principles of equity
    (regardless of whether enforcement is considered in a proceeding in equity
    or at law).

3.  The New Securities and the guarantees of the New Securities provided by the
    Guarantors (the "Guarantees") will, upon the issuance and authentication of
    the New Securities and exchange thereof for the Old Securities in the manner
    referred to in the Registration Statement, the Indenture and the Sixth
    Supplemental Indenture, constitute valid and binding obligations of the
    Funding Corporation and the Guarantors, respectively, enforceable against
    the Funding Corporation and the Guarantors, respectively, in accordance with
    their terms, except as enforcement thereof may be limited by bankruptcy,
    insolvency, reorganization, fraudulent conveyance and other similar laws
    affecting the enforcement of creditors' rights generally and except as
    enforcement thereof is subject to general principles of equity (regardless
    of whether enforcement is considered in a proceeding in equity or at law).

     This opinion is limited to the laws of the State of New York, the General
Corporation Law of the State of Delaware and the federal laws of the United
States of the type typically applicable to transactions contemplated by the
Exchange Offer, and we do not express any opinion with respect to the laws of
any other country, state or jurisdiction.

     This letter speaks only as of the date hereof and is limited to present
statutes, regulations and administrative and judicial interpretations. We
undertake no

responsibility to update or supplement this letter after the date
hereof.

     We consent to being named in the Registration Statement and related
Prospectus as counsel who are passing upon the legality of the New Securities
and the Guarantees for the Funding Corporation and for the Guarantors,
respectively, and to the reference to our name under the caption "Legal Matters"
in such Prospectus. We also consent to your filing copies of this opinion as an
exhibit to the Registration Statement or any amendment thereto.



Very truly yours,
