Re:   Public Service Enterprise Group Incorporated  -
      Registration Statement on Form S-3

Ladies and Gentlemen:

      I  am  Associate  General  Counsel  of  Public  Service  Enterprise  Group
Incorporated,  a New Jersey corporation ("PSEG"),  and am rendering this opinion
in connection  with the  preparation and filing with the Securities and Exchange
Commission ("the  Commission") under the Securities Act of 1933, as amended (the
"Act"), of a Registration  Statement on Form S-3 (the "Registration  Statement")
relating  to the  registration  under  the Act of:  (i)  unsecured  senior  debt
securities and unsecured subordinated debt securities, consisting of debentures,
notes or other evidence of indebtedness, of PSEG (the "Debt Securities"),  which
may be issued  pursuant to a Senior Debt Indenture  dated as of November 1, 1998
between PSEG and US Bank National Association,  as successor trustee (as amended
or supplemented,  the "Senior Debt Indenture") or a Subordinated  Debt Indenture
to be entered into between PSEG and US Bank National  Association,  as successor
trustee (as amended or  supplemented,  the  "Subordinated  Debt  Indenture" and,
together with the Senior Debt Indenture,  the "Indentures");  and any applicable
Supplemental  Indenture  under the  Indentures;  (ii)  shares  of common  stock,
without  par value,  of PSEG (the  "Common  Stock"),  including,  under the PSEG
Dividend  Reinvestment  and Stock  Purchase Plan (the  "Plan");  (iii) shares of
series of preferred stock,  without par value (the "Preferred  Stock"), of PSEG;
(iv) stock purchase  contracts of PSEG to purchase Common Stock ("Stock Purchase
Contracts");  and (v) stock purchase units of PSEG, each representing  ownership
of a


                                       2


Stock Purchase  Contract and any Debt  Securities,  or debt obligations of third
parties,  including U.S. Treasury securities,  securing a holder's obligation to
purchase Common Stock under the Stock Purchase  Contract ("Stock Purchase Units"
and, together with the Debt Securities,  Common Stock, Preferred Stock and Stock
Purchase Contracts, the "Securities").

      I and/or  attorneys  working  under my  supervision  have  conducted  such
investigations of laws and regulations as I have deemed necessary or appropriate
for the purpose of rendering the opinions hereinafter expressed.

      The opinions expressed below are based on the following assumptions:

      (a) the Registration Statement will have become effective;

      (b) the proposed transactions  contemplated by the Registration  Statement
will have been carried out on the basis set forth therein and in conformity with
the authorizations,  approvals, consents or exemptions under the securities laws
of various states and other jurisdictions of the United States;

      (c) prior to the  issuance  of any  series of Debt  Securities,  shares of
Preferred Stock, Stock Purchase Contracts and Stock Purchase Units, the Board of
Directors of the Company (the  "Board"),  a committee  thereof,  or the Sale and
Pricing Committee of the Company pursuant to delegated authority from the Board,
will have: (i) authorized the  Subordinated  Debt Indenture and any Supplemental
Indentures under the Indentures, the Stock Purchase Contracts and Stock Purchase
Units; (ii) authorized the issuance of, and established the terms of such series
of Debt  Securities,  series of Preferred  Stock,  Stock Purchase  Contracts and
Stock Purchase  Units,  and (iii)  authorized the issuance of such Common Stock;
and

      (d) the  Indentures  will  have  been  qualified  in  accordance  with the
provisions of the Trust Indenture Act of 1939, as amended;

      (e) the  Senior  Debt  Indenture,  any  Supplemental  Indenture  under the
Indentures,   the  Stock  Purchase  Contracts,  Stock  Purchase  Units  and  all
collateral  and  related   agreements  will  have  been  properly  executed  and
delivered;

      (f) the Debt Securities will have been properly  executed,  authenticated,
issued and delivered as provided in the Indenture;

      (g) a Certificate of Amendment to the Certificate of Incorporation of PSEG
setting forth the terms of the Preferred Stock will have been executed and filed
with the State of New Jersey, and the Preferred Stock will have been duly
issued, paid for and delivered;

      (h) the Common Stock will have been duly issued,  paid for and  delivered,
including  previously  unissued  shares of Common Stock in  accordance  with the
terms of the Plan.


                                       3


      Based upon the foregoing and subject to the  limitations  herein,  I am of
the opinion that:

      1. The Company is a corporation  duly organized and validly existing under
the laws of the State of New Jersey.

      2. The Debt Securities,  Stock Purchase Contracts and Stock Purchase Units
will  be  legally  issued,   valid  and  binding  obligations  of  the  Company,
enforceable in accordance with their terms.

      3. The Common Stock and the Preferred Stock will be legally issued,  fully
paid and non-assessable.

      I express no opinions as to matters of law in jurisdictions other than the
State of New Jersey.  My opinions are rendered  only with respect to the laws of
the State of New Jersey and rules,  regulations and orders  thereunder which are
currently in effect.

      This opinion does not cover the necessity of filings under the  provisions
of securities laws of any state in which the Securities may be sold.

      The opinion set forth in paragraph 2. above is subject, as to enforcement,
to (i) bankruptcy,  insolvency (including, without limitation, all laws relating
to  fraudulent  transfers),  reorganization,  moratorium  or other  similar laws
relating to or affecting the enforcement of creditors' rights generally and (ii)
general equitable principles (regardless of whether enforcement is considered in
a proceeding in equity or at law).

      I  hereby  consent  to  the  use  of  this  opinion  as  Exhibit  5 to the
Registration  Statement  and to the  reference  to me under the  heading  "Legal
Matters" in the Prospectus contained therein.

                                                       Very truly yours,

                                                       /s/ James T. Foran
