                          INDEPENDENT AUDITORS' REPORT



Employee Benefits Committee of
Public Service Enterprise Group Incorporated:


     We have audited the  accompanying  statements  of net assets  available for
benefits of the Public Service  Enterprise Group  Incorporated  Employee Savings
Plan (the "Plan") as of December 31, 2001 and 2000, and the related statement of
changes in net assets  available  for benefits  for the year ended  December 31,
2001.  These  financial   statements  are  the   responsibility  of  the  Plan's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

     We conducted our audits in accordance  with  auditing  standards  generally
accepted in the United States of America.  Those standards  require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

     In our opinion,  such financial  statements present fairly, in all material
respects, the net assets available for benefits of the Plan at December 31, 2001
and 2000,  and the changes in net assets  available  for  benefits  for the year
ended  December 31, 2001 in  conformity  with  accounting  principles  generally
accepted in the United States of America.

                          NOTES TO FINANCIAL STATEMENTS

1. DESCRIPTION OF THE PLAN

General

     The  following   description  of  the  Public  Service   Enterprise   Group
Incorporated  (Company)  Employee  Savings  Plan (Plan) is provided  for general
information  purposes only.  Participants  should refer to the Plan Document for
more complete information.

     The Plan was adopted as a tax qualified  profit  sharing plan under section
401(a) of the Internal  Revenue Code of 1986, as amended,  (IRC) and a qualified
cash or deferred  arrangement  under IRC section 401(k) to encourage  thrift and
savings by eligible  bargaining unit employees  (Eligible  Employees).  Deutsche
Bank is the Trustee of the Master Trust established pursuant to the Plan. Hewitt
Associates is the Record Keeper for the Plan.

     The Plan is generally  subject to the  provisions of Titles I and II of the
Employee  Retirement  Income  Security Act of 1974 (ERISA),  including,  but not
limited to, the provisions with respect to reporting, disclosure, participation,
vesting and fiduciary responsibility.  However, it is not subject to the funding
requirements  of Title I and benefits  under the Plan are not  guaranteed by the
Pension Benefit Guarantee Corporation under Title IV of ERISA.

     The Plan was last amended  effective  January 1, 2002.  Effective with that
date, catch-up  contributions of an additional $1,000 in pre-income tax deposits
for  employees  age 50 or  older in 2002  were  implemented,  maximum  permitted
employee  contribution  increased  from  25% to  50%,  acceptance  of  after-tax
rollovers and rollovers from financial  institutions were implemented,  Internal
Revenue Service (IRS) minimum  distribution  requirements  were  implemented for
post age 70 1/2 distributions,  the suspension period for making deposits to the
Plan after a hardship  withdrawal  was decreased from one year to six months and
the  Company  stock fund  converted  to an  employee  stock  ownership  plan and
dividends on Company Stock can be made in cash. Certain other provisions of this
amendment are discussed below.

     The  Plan  permits,  among  other  things,  participation  in the  Plan  by
Affiliates  of the  Company  and their  bargaining  unit  employees  (each  such
participating Affiliate with the Company is an "Employer"). Participation in the
Plan is entirely voluntary.

     An employee may  participate in the Plan from the date of hire. The Company
begins matching contributions when an employee has completed one Year of Service
as defined by the Plan.  The Company  also  maintains a Thrift and Tax  Deferred
Savings Plan (Thrift Plan) to provide for its non-represented  employees. At the
time any  employee who is a  Participant  in the Thrift Plan becomes an Eligible
Employee for the Plan, that employee will automatically be enrolled in the Plan,
all  balances  in the  Thrift  Plan  will be  transferred  to the  Plan  and all
contributions and investment elections in effect for the Thrift Plan will remain
in effect in the  Plan.  Certain  Eligible  Employees  may also  elect to have a
distribution  from another  qualified  corporate plan  contributed as a rollover
contribution  with the approval of the  Company's  Employee  Benefits  Committee
(Committee), the Plan Administrator.


     During 2000,  the Company  acquired  Fluidics,  Inc. and Arden  Engineering
Constructors,  Inc. As a result of these transactions,  the savings plans of the
acquired  companies  were  merged  with and into the Plan and the  Thrift  Plan.
Combined participant account balances of $460,276 were transferred into the Plan
during 2001.

Deposits and Contributions

     Under the Plan, each  Participant,  except as otherwise noted, may elect to
make basic deposits to Investment  Funds of such  Participant's  choosing within
the Savings Account Fund of 1% - 7% of his/her  Compensation  (Basic  Deposits),
and his/her Employer will contribute an amount equal to 50% thereof,  subject to
certain exceptions and limitations (Employer  Contributions).  Prior to March 1,
2002, Employer  Contributions for Participants with respect to Basic Deposits in
excess of 5% and up to 7% of  Compensation  were made in shares of the Company's
Common Stock and were not available for transfer to any other Investment Fund or
withdrawal from the Plan prior to the  Participant's  termination of employment.
Effective March 1, 2002, Employer Contributions for Participants with respect to
Basic Deposits in excess of 5% and up to 7% of Compensation are made in cash and
invested  according to the participant's  investment  election and any shares of
Company Stock held in a  Participant's  account are eligible for transfer to any
other Investment Fund. In addition, a Participant may elect to make supplemental
deposits to his/her  Savings Account Fund in increments of 1% of Compensation up
to  an  additional  18%  (43%  effective   January  1,  2002)  of   Compensation
(Supplemental   Deposits),   subject  to  certain   limitations,   without   any
corresponding  matching Employer  Contribution.  Participants may designate such
Basic and/or Supplemental Deposits as post-income tax contributions (Nondeferred
deposits) or pre-income tax contributions (Deferred Deposits).

     Each  Participant  may  also,  within  any  Plan  Year,  make  one or  more
Additional  Lump Sum Deposits on a Nondeferred  basis in minimum amounts of $250
and in such total amounts which, when aggregated with such  Participant's  Basic
Deposits and Supplemental Deposits, do not exceed 25% of his or her Compensation
for that Plan Year and  subject to the  limitations  of the IRC.  As  previously
stated, as of January 1, 2002, maximum permitted employee contribution increased
from 25% to 50%.

     The maximum amount of Deferred Deposits to a Participant's  Savings Account
may have to be limited to meet  requirements  of the IRC. The extent of any such
limitation  will be determined  from time to time by the Committee  based on the
actual pattern of Deferred Deposits by all  Participants.  All Deferred Deposits
in excess of such  percentage  will  automatically  be  treated  as  Nondeferred
Deposits  and will result in taxable  income to the affected  Participants.  The
Committee  will  attempt to assure that any such  limitation  will apply only to
future contributions,  but it is possible that, in order to meet requirements of
the  IRC,  the  limitation  will,  in some  circumstances,  have  to be  applied
retroactively.  Deferred  Deposits  may not  generally  be  withdrawn  until age
59-1/2.  Nondeferred  Deposits,  on the other hand, may be withdrawn at any time
subject to certain penalties and restrictions.

     Savings  Account  Deposits  are  made  through  payroll  deductions  by the
Employer,  rollover contributions from other qualified plans and Additional Lump
Sum  Deposits.   Deposits  by  Participants  and  Employer   Contributions   are
transferred to a Trustee and separately  held in the Plan's Savings Account Fund
of the Master Trust Fund for Investment and other  transactions,  as directed by
Participants.  Each  Participant is entitled to choose the  Investment  Funds in
which his/her  Deposits and Employer  Contributions  will be invested from among
the Investment Funds offered under the Plan,  except for Employer  Contributions
with  respect  to Basic  Deposits  in excess of 5% for all  others,  which  were
invested  in the  Enterprise  Common  Stock  Fund  prior to March  1,  2002,  as
discussed above.

     Dividends,  interest and other income  attributable to each Investment Fund
of the Plan are  reinvested in that  Investment  Fund to the extent they are not
used to pay direct expenses of that Investment Fund.

     All  Deposits  and  Employer  Contributions  in the  Stable  Value Fund are
invested in either traditional  Guaranteed Investment Contracts (GICs) issued by
insurance  companies or other  financial  intermediaries  (Traditional  GICs) or
Benefit Responsive  Agreements (Synthetic GICs) which are similar to Traditional
GICs in terms of their  ability to preserve  principal and provide a stable rate
of return.  Synthetic GICs are different in that they are backed or secured by a
separate  portfolio of  high-quality  fixed income  securities that are directly
owned by the Plan. The portfolio is wrapped by a "book value wrapper", usually a
financial  institution  other than the investment  manager of the Synthetic GIC,
which provides a crediting  rate and which  guarantees  that benefit  repayments
will be made at book value. Deposits and Employer Contributions earn interest at
the composite  rate of all GICs in which the assets of the Stable Value Fund are
then invested. Such rate varies as such Traditional and Synthetic GICs mature or
are entered  into,  and as Deposits and Employer  Contributions  are made to and
withdrawn  from such  contracts.  Under the contracts in effect during 2001, the
composite  rate of interest  earned by such assets so invested was not less than
5.81%.

     Employee  Stock  Ownership  Plan  Fund  (ESOP  Fund)  Participants  receive
quarterly  payments directly from the Trustee equal to the dividends paid to the
Trustee on the shares of the Company's Common Stock held for their ESOP Fund.

Participant Loans

     The Trustee may, subject to the approval of the Director of Performance and
Rewards of PSEG Services  Corporation,  lend a Participant  an amount up to: the
lesser of 50% of the value of the vested portion of such  Participant's  Savings
Account and ESOP Fund but no more than the aggregate value of such Participant's
Savings Account or $50,000, whichever is less. However, no amounts may be loaned
directly  from any ESOP  Account,  from any portion of a  Participant's  Savings
Account  attributable to transfers from the Cash Balance from assets held in the
Schwab Personal Choice Retirement  Account Fund, or prior to April 1, 2002, from
any  portion of the  Enterprise  Common  Stock  Fund  attributable  to  Employer
Contributions  made in  shares  of  stock.  Any  Participant  loan must be for a
principal  amount of $1,000  or more and no  Participant  may have more than two
loans outstanding at any time. All loans,  including  interest thereon,  must be
repaid by payroll deductions in equal monthly installments of 12 to 60 months as
selected by the Participant.  However, a Participant may prepay any such loan in
full or in part in a lump sum in accordance with such rules as are prescribed by
the  Committee.  A  Participant  may not  apply  for  more  than one loan in any
calendar  year. A loan to a  Participant  is  considered  an  investment of such
Participant's  Savings Account and repayments of principal of any loan, together
with interest thereon,  are invested in the Savings Account  Investment Funds of
the Plan in accordance with the Participant's  then-current investment direction
for Deposits and Employer Contributions.

     Each loan bears interest at a rate fixed from time to time by the Committee
taking into consideration the then-current interest rates being charged by other
lenders. The rate of interest applicable to any loan at its inception remains in
effect for the duration of such loan. During 2001 and 2000, the rate of interest
on loans granted to  Participants  ranged between 6.0% to 9.5% and 8.5% to 9.5%,
respectively.

     Loan amounts are taken from sub-accounts of a Participant's Savings Account
in the following order:

     (a)  Deferred Deposits
     (b)  Unmatured vested Employer Contributions
     (c)  Matured vested Employer Contributions
     (d)  Rollover Contributions
     (e)  Unmatured post-1986 Nondeferred Deposits
     (f)  Matured post-1986 Nondeferred Deposits
     (g)  Pre-1987 Nondeferred Deposits

     Each loan is secured by an  assignment of the  Participant's  entire right,
title and interest in and to the Master Trust Fund to the extent of the loan and
accrued interest thereon.

Forfeitures

     Any nonvested  portion of the Participant's  Account,  determined as of the
date of  severance  from  employment,  shall be  forfeited  and shall be applied
thereafter to reduce a subsequent  contribution or contributions of the Employer
as provided in the Plan  Document.  If such former  Participant is rehired by an
Employer  on or before the end of and is  employed  by an Employer at the end of
the fifth Plan Year after the Plan Year in which such severance  occurred,  then
such nonvested portion of the  Participant's  Account shall be reinstated by the
Employer and the  Participant's  right  thereto  shall be  determined  as if the
Participant had not terminated employment,  provided that the Participant repays
to the Plan the amount of any distribution  paid to him or her on account of the
severance  from  employment.  Unallocated  forfeitures  to be used for  reducing
future  contributions  as of December 31, 2001 and 2000  amounted to $95,968 and
$94,433, respectively.

Participant Accounts

     Individual  accounts are maintained for each  Participant  which consist of
the  following  subaccounts:  Basic  Deposit  Subaccount,  Supplemental  Deposit
Subaccount  and  Employer  Contribution  Subaccount,  the  assets  of which  are
invested  pursuant to the direction of the Participant.  The assets of each such
subaccount of the Savings Account are identified as Nondeferred or Deferred.



Vesting

     Except for amounts  transferred  from the Cash  Balance Plan into the Plan,
since May 1, 2002, Employer Contributions to a Participant's Savings Account are
fully vested.  Prior to that time, Employer  Contributions vested according to a
5-year cliff vesting  schedule.  Amounts  transferred from the Cash Balance Plan
follow the Cash Balance Plan vesting  regulations  and vest upon a Participant's
completion  of five years of service  with an  Employer,  or when a  Participant
reaches the age of 65, is disabled,  laid off or dies. All amounts credited to a
Participant's ESOP Fund are fully vested.

Holding Account

     The Holding Account is a vehicle to record the transactions either from one
Investment  Fund to another  Investment  Fund or from an  Investment  Fund to an
outside  source.  Daily  balances  which  remain  in  the  Holding  Account  are
temporarily  invested in  short-term,  liquid  investments  by the Trustee until
disbursement.  Activity within the Holding Account includes inflows and outflows
of cash related to Investment Fund transfers,  Deposits, Employer Contributions,
withdrawals, receipts of dividends and interest, expenses incurred in connection
with the administration of the Plan, benefit payments and loan transactions.

Penalties Upon Withdrawal

     If a Participant  withdraws vested Employer  Contributions  and/or Deposits
before they have been in the Plan for twenty-four  months, such Participant will
lose the matching Employer  Contributions on Deposits made during the subsequent
three months.  Distributions  to Participants  electing to withdraw  Nondeferred
Deposits and Employer  Contributions  are made as soon as practicable after such
elections are received by the Plan's Record Keeper.  Nondeferred Deposits may be
withdrawn at any time, but certain  penalties may apply.  Deferred  Deposits may
not be withdrawn  during  employment  prior to age 59-1/2  except for reasons of
extraordinary  financial  hardship  and  to the  extent  permitted  by  the  IRC
(hardship  withdrawals).  Distributions  to  Participants  of approved  hardship
withdrawals are made as soon as practicable after such approval.

Payment of Benefits

     Benefit  payments to Participants are recorded upon  distribution.  Amounts
allocated to accounts of persons who have elected to withdraw  from the plan but
have not yet been paid were  $249,211  and  $216,158 as of December 31, 2001 and
2000, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

     The financial statements of the Plan have been prepared on an accrual basis
in accordance with accounting principles generally accepted in the United States
of America.

Use of Estimates

     The  preparation  of financial  statements  in conformity  with  accounting
principles   generally  accepted  in  the  United  States  of  America  requires
management to make estimates and assumptions that affect the reported amounts of
net assets  available  for benefits and changes  therein.  Actual  results could
differ from those estimates.

Risks and Uncertainties

     The Plan provides for various investment  options.  The mutual funds invest
in various  securities  including  U.S.  Government  securities,  corporate debt
instruments and corporate stocks. Investment securities, in general, are exposed
to various risks, such as interest rate,  credit and overall market  volatility.
Due to the level of risk associated with certain  investment  securities,  it is
reasonably  possible  that changes in the values of investment  securities  will
occur  in  the  near  term  and  that  such  changes  could  materially   affect
participants'  account  balances and the amount reported in the statement of net
assets available for Plan benefits.

Investment Valuation and Income Recognition

     The investments in the Master Trust are stated at fair value except for its
benefit-responsive  investment  contract  with the Stable  Value Fund,  which is
recorded  at  contract  value,   which   approximates  fair  value.  The  Plan's
investments  in the  guaranteed  annuity  contracts of the Stable Value Fund are
with  various  insurance  companies  and are recorded at contract  value,  which
approximates  fair value,  and is calculated as cost plus  accumulated  interest
less  withdrawals (see Note 3). Quoted market prices are used to value all other
investments. Shares of mutual funds are valued at adjusted cost of the net asset
value of shares  held by the Plan at  year-end.  The  adjusted  cost is the fair
value of the  security at the  beginning  of the Plan Year,  or cost if acquired
since that date.  Purchases and sales of securities are recorded on a trade-date
basis.  Temporary investments are stated at cost, which approximates fair market
value.  Dividend  income  is  recorded  on the  ex-dividend  date.  The loans to
participants are valued at outstanding  principle balance plus accrued interest,
which approximates fair value.

     Investment gains and losses from securities transactions are computed using
an adjusted cost basis as  prescribed  by the  Department of Labor's (DOL) Rules
and Regulations for Reporting and Disclosure.

Administrative Expenses of Plan

     All expenses incurred for the  administration of the Plan,  including taxes
and brokerage costs, are deducted from the Master Trust Fund.

     The  assets  of the  Enterprise  Common  Stock  Fund and the ESOP  Fund are
invested in shares of the Company's Common Stock. Shares of the Company's Common
Stock required for the Enterprise Common Stock Fund are purchased by the Trustee
either  directly  from the  Company at its sole  discretion,  on the open market
through a broker or from the ESOP Fund. In situations  where the ESOP Fund is in
a "sell"  position and the Enterprise  Common Stock Fund is in a "buy" position,
the  Enterprise  Common  Stock  Fund will buy from the ESOP Fund at the  closing
price on the New York Stock  Exchange  for that day. In such case,  no brokerage
commissions will be charged on the transaction.  Otherwise,  all shares sold for
the  Enterprise  Common  Stock Fund and the ESOP Fund are sold by the Trustee on
the open market through a broker. The proceeds, net of brokerage commissions and
transfer taxes, are distributed to the  Participant.

Transfers of the ESOP Fund to Savings Account

     Participants  are  permitted to transfer all, but not less than all, of the
shares of the  Company's  Common  Stock from  their ESOP Funds to their  Savings
Accounts.  To  effect  such  transfers,  the  Trustee  will  sell the  shares of
Enterprise  Common  Stock held in the ESOP Fund and invest the  proceeds  in the
Savings Account  Investment Funds designated by the Participant.  The cash value
of each share of the  Company's  Common Stock  transferred  will be equal to the
price per share of the Company's Common Stock actually  received by the Trustee.
Any such transfer is treated as a rollover contribution.

Recently Adopted Accounting Principle

     In June 1998, the Financial  Accounting Standards Board issued Statement of
Financial  Accounting  Standards  (SFAS) No.  133,  "Accounting  for  Derivative
Instruments and Hedging  Activities" (SFAS 133), which was later amended by SFAS
No. 138. Effective January 1, 2001, the Plan adopted this statement, as amended.
Adoption of SFAS 133 had no impact on the Plan's  financial  position or results
of operations.

Reclassifications

     Certain prior year amounts have been reclassified to conform to the current
year presentation.

3. INVESTMENT OF THE PLAN AND THRIFT PLAN IN THE MASTER TRUST

     The  Plan's  investments  are  included  in the  Master  Trust,  which  was
established  for the  investment  of  assets of all of the  Company's  qualified
retirement  plans  including the Plan and the Thrift Plan. The following  tables
present  the  fair  values  of  and  the  investment  income  recognized  by the
investments  of the Plan and Thrift Plan in the Master  Trust as of December 31,
2001 and 2000 and for the year ended  December 31, 2001. As of December 31, 2001
and  2000,  the  Plan's  interests  in such  assets  of the  Master  Trust  were
approximately 39% and 38%, respectively.

4. INVESTMENTS

The Master Trust includes the following:

A.   Savings Account Investment Funds

(1)  The assets of the Stable Value Fund are primarily  invested in  Traditional
     GICs  or  Synthetic  GICs  with  additional  investments  in the  Trustee's
     short-term  investment  fund.  All GIC  contract  values  approximate  fair
     values.  As of December 31, 2001,  the Plan's  interest in the Stable Value
     Fund was approximately 39%. At December 31, 2001, the Stable Value Fund was
     comprised of the following:

Revenue  Code of 1986 (the  "Code") and is intended to be exempt  under  Section
501(a) of the Code.  The Plan  received a  favorable  Internal  Revenue  Service
determination  letter  dated  April 8, 1998.  The Plan has since  been  amended.
However,  the Plan  Administrator  believes  that the  Plan is  currently  being
operated in compliance with the applicable  requirements of the Code. Therefore,
no  provision  for  income  taxes  has been  included  in the  Plan's  financial
statements.

reserved the right to amend,  suspend or terminate  the Plan at any time. In the

is  the  Plan  Sponsor;   these   transactions   qualify  as   party-in-interest
transactions. Certain administrative functions are performed by the officers and
employees of the Company (who may also be  participants  of the Plan) at no cost
to the Plan.  These  transactions  are not deemed  prohibited  party-in-interest
transactions, because they are covered by statutory or administrative exemptions
