Exhibit 3.9

                                 TRUST AGREEMENT

"Trustees"). The Depositor and the Trustees hereby agree as follows:

      1. The trust created hereby shall be known as "PSEG Power Capital Trust

provided herein, may conduct the business of the Trust, make and execute
contracts, and sue and be sued.

      2. The Depositor hereby assigns, transfers conveys and sets over to the

Trust created hereby constitutes a statutory trust under Chapter 38 of Title 12
of the Delaware Code, 12 Del. C. ss. 3801, et seq. (the "Statutory Trust Act"),
and that this document constitutes the governing instrument of the Trust. The
Trustees are hereby authorized and directed to execute and file a certificate of
trust with the Delaware Secretary of State in accordance with the provisions of
the Statutory Trust Act.

      3. The Depositor and the Trustees will enter into an amended and restated

and the issuance of the Preferred Securities and Common Securities referred to
therein. Prior to the execution and delivery of such amended and restated Trust
Agreement, the Trustees shall not have any duty or obligation hereunder or with
respect to the trust estate, except as otherwise required by applicable law or
as may be necessary to obtain prior to such execution and delivery any licenses,
consents or approvals required by applicable law or otherwise. Notwithstanding
the foregoing, the Trustees may take all actions which the Depositor deems
necessary, convenient or incidental to effect the transactions contemplated
herein and as the Trustees shall be directed in writing by the Depositor.

      4. The Depositor, as the depositor of the Trust, is hereby authorized (i)
to file with the Securities and Exchange Commission (the "Commission") and
execute, in each case on behalf of the Trust, (a) the Registration Statement on
Form S-3 or other appropriate form (the "1933 Act Registration Statement"),
including any pre-effective or post-effective amendments to the 1933 Act
Registration Statement (including any preliminary prospectus, prospectus or
prospectus supplements, and the exhibits contained therein), relating to the
registration under the Securities Act of 1933, as amended, of the Preferred
Securities of the Trust and possibly certain other securities and (b) a
Registration Statement on Form 8-A or other appropriate form (the

exchange or The Nasdaq Stock Market (each, an "Exchange") and execute on behalf
of the Trust one or more listing applications and all other applications,
statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities to be listed on any of the
Exchanges; (iii) to file and execute on behalf of the Trust such applications,
reports, surety bonds, irrevocable consents, appointments of attorney for

filing referred to in clauses (i), (ii) and (iii) above is required by the rules
and regulations of the Commission, an Exchange or state securities or blue sky
laws, to be executed on behalf of the Trust by any of the Trustees, Mark G.
Kahrer, in his capacity as a trustee of the Trust, is hereby authorized and
directed to join in any such filing and to execute on behalf of the Trust any
and all of the foregoing. In connection with all of the foregoing, the Depositor
hereby constitutes and appoints Mark G. Kahrer as its true and lawful
attorney-in-fact and agent, with full power of substitution and resubstitution,
for the Depositor or in the Depositor's name, place and stead, in any and all
capacities, to sign any and all amendments (including post-effective amendments)
to the 1933 Act Registration Statement and the 1934 Act Registration Statement
and to file the same, with all exhibits thereto, and other documents in
connection therewith, with the Commission, granting unto said attorney-in-fact
and agent full power and authority to do and perform each and every act and
thing requisite and necessary to be done in connection therewith, as fully to
all intents and purposes as the Depositor might or could to in person, hereby
ratifying and confirming all that said attorney-in-fact and agent, or his
respective substitute, shall do or cause to be done by virtue hereof.

      5. This Trust Agreement may be executed in one or more counterparts.

      6. The number of Trustees initially shall be three (3) and thereafter the
number of Trustees shall be such number as shall be fixed from time to time by a
written instrument signed by the Depositor which may increase or decrease the
number of Trustees; provided, however, that to the extent required by the
Statutory Trust Act, one Trustee shall either be a natural person who is a
resident of the State of Delaware or, if not a natural person, an entity which
has its principal place of business in the State of Delaware and otherwise meets
the requirements of applicable Delaware law. Subject to the foregoing, the
Depositor is entitled to appoint or remove without cause any Trustee at any
time. The Trustees may resign upon thirty (30) days' prior notice to the
Depositor.

      7. The Depositor hereby agrees, to the fullest extent permitted by
applicable

law, to (i) reimburse the Trustees for all reasonable expenses (including
reasonable fees and expenses of counsel and other experts) and (ii) indemnify,

against any and all losses, damages, liabilities, claims, actions, suits, costs,
expenses, disbursements (including the reasonable fees and expenses of counsel),
taxes and penalties of any kind and nature whatsoever (collectively,
"Expenses"), to the extent that such Expenses arise out of or are imposed upon
or asserted at any time against such Indemnified Persons with respect to the
performance of this Trust Agreement, the creation, operation or termination of
the Trust or the transactions contemplated hereby; provided, however, that the
Depositor shall not be required to indemnify any Indemnified Person for any
Expenses which are a result of the willful misconduct, bad faith or gross
negligence of such Indemnified Person.

      8. The Depositor may, in its sole discretion, dissolve and terminate the
Trust.

      9. This Trust Agreement shall be governed by, and construed in accordance
with, the laws of the State of Delaware (without regard to conflict of laws
principles).
