         Re:      CalEnergy Capital Trust II

Ladies and Gentlemen:

                  We have acted as special Delaware counsel to CalEnergy
Capital Trust II, a Delaware statutory business trust (the "Trust"), in
connection with certain matters of Delaware law relating to (i) the issuance of
the 6-1/4% Trust Convertible Preferred Securities (the "Preferred Securities")
to the several initial purchasers named in the Purchase Agreement (the "Initial
Purchasers") dated February 20, 1997 (the "Purchasers") dated February 20, 1997
(the "Purchase Agreement") among the Initial Purchasers, the Trust and
CalEnergy Company, Inc., a Delaware corporation (the "Company") and (ii) the
registration of 3,600,000 Preferred Securities pursuant to Registration
Statement No. 333-30537 on Form S-3 as filed by the Trust and the Company with
the Securities and Exchange Commission on July 1, 1997 and Pre-Effective
Amendment No. 1 thereto as filed on the date hereof (as so amended, the 
"Registration Statement").

                  The Preferred Securities have been issued pursuant to the
Purchase Agreement and the Amended and Restated Declaration of Trust of the
Trust dated as of February 26, 1997 (the "Governing Instrument"). Capitalized
terms used herein and not otherwise herein defined are used as defined in the
Governing Instrument.

                  In rendering this opinion, we have examined and relied upon
copies of the following documents in the forms provided to us: the Certificate
of Trust of the Trust as filed in the Office of the Secretary of State of the
State of Delaware (the "State Office") on February 13, 1997 (the "Certificate");
a Declaration of Trust dated as of February 13, 1997 (the "Original Governing
Instrument"); the Governing Instrument; the form of Indenture dated as of 
February 26, 1997 between the Company and The Bank of New York, as Trustee; the
Purchase Agreement; the Trust's Offering Memorandum dated February 20, 1997 
relating to the Preferred Securities (the

"Memorandum"); the Registration Statement; the Registration Rights Agreement 
dated February 26, 1997 among the Trust, the Company, Lehman Brothers Inc. 
and Donaldson, Lufkin & Jenrette Securities Corporation (the "Registration
Rights Agreement"); and a certificate of good standing of the Trust obtained
as of a recent date from the State Office. In such examinations, we have assumed
the genuineness of all signatures, the conformity to original documents of all
documents submitted to us as drafts or copies or forms of documents to be 
executed and the legal capacity of natural persons to complete the execution of
documents. We have further assumed for purposes of this opinion: (i) the due
formation or organization, valid existence and good standing of each entity 
other than the Trust that is a party to any of the documents reviewed by us 
under the laws of the jurisdiction of its respective formation or organization;
(ii) the due authorization, execution and delivery by, or on behalf of, each of
the parties thereto of the above-referenced documents; (iii) that no event has
occurred subsequent to the filing of the Certificate that would cause a 
dissolution or liquidation of the Trust under the Original Governing Instrument
or the Governing Instrument, as applicable; (iv) that the activities of the 
Trust have been and will be conducted in accordance with the Original Governing
Instrument or the Governing Instrument, as applicable, and the Delaware Business
Trust Act, 12 Del. C. Sections 3801 et seq. (the "Delaware Act"); (v) that each
Holder of Preferred Securities has made payment of the required consideration 
therefor and received a Preferred Securities Certificate in consideration 
thereof in accordance with the terms and conditions of the Governing Instrument,
the Memorandum and the Purchase Agreement; (vi) that the Preferred Securities 
have been issued and sold to, and held or transferred by, the Preferred 
Securities Holders (and any subsequent transferee), and all transfers have been
made, in accordance with the terms, conditions, requirements and procedures set
forth in the Governing Instrument, the Memorandum, the Purchase Agreement and, 
as applicable, the Registration Statement; (vii) that none of the Preferred 
Securities has been called for redemption, redeemed, converted or canceled 
(except in connection with a permitted transfer) and all of the Preferred 
Securities remain outstanding; (viii) that the Sponsor has directed the Regular
Trustees to take the actions contemplated by Section 3.6(b) of the Governing 
Instrument; and (ix) that the documents examined by us are in full force and 
effect, express the entire understanding of the parties thereto with respect to
the subject matter thereof and have not been amended, supplemented or otherwise
modified, except as herein referenced. No opinion is expressed with respect to 
the requirements of, or compliance with, federal or state securities or blue sky
laws. We have not participated in the preparation of the Memorandum, the 
Registration Statement or any other offering materials relating to the 
Securities and we assume no responsibility for their contents. As to any fact 
material to our opinion, other than those assumed, we have relied without 
independent investigation on the above-referenced

documents and on the accuracy, as of the date hereof, of the matters therein
contained.

                  Based on and subject to the foregoing, and limited in all
respects to matters of Delaware law, it is our opinion that the Preferred
Securities constitute validly issued and, subject to the qualifications set
forth below, fully paid and nonassessable beneficial interests in the assets of
the Trust. We note that pursuant to Section 11.04 of the Governing Instrument,
the Trust may withhold amounts otherwise distributable to a Holder and pay over
such amounts to the applicable jurisdictions in accordance with federal, state
and local law and any amount withheld will be deemed to have been distributed
to such Holder and that, pursuant to the Governing Instrument, Preferred
Security Holders may be obligated to make payments or provide indemnity or
security under the circumstances set forth therein.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of our name under the heading
"LEGAL MATTERS" in the Prospectus forming a part thereof. In giving this
consent, we do not thereby admit that we come within the category of persons
whose consent is required under Section 7 of the Securities Act of 1933, as
amended, or the rules and regulations of the Securities and Exchange Commission
thereunder. This opinion speaks only as of the date hereof and is based on our
understandings and assumptions as to present facts, and on our review of the
above-referenced documents and the application of Delaware law as the same
exist as of the date hereof, and we undertake no obligation to update or
supplement this opinion after the date hereof for the benefit of any person or
entity with respect to any facts or circumstances that may hereafter come to
our attention or any changes in facts or law that may hereafter occur or take
effect. This opinion is intended solely for the benefit of the addressee hereof
in connection with the matters contemplated hereby and may not be relied on by
any other person or entity or for any other purpose without our prior written
consent.

                                      Very truly yours,



                                      /s/ MORRIS, NICHOLS, ARSHT & TUNNELL
