EXHIBIT 31

Certification Pursuant to Rules13a-14 and 15d-14
of the 1934 Securities Exchange Act

I, E. James Ferland, certify
that:

1.

I
have reviewed this Quarterly Report on Form 10-Q of Public Service Enterprise
Group Incorporated;

2.

Based
on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

3.

Based
on my knowledge, the financial statements, and other financial information
included in this report, fairly present in all material respects the financial
condition, results of operations and cash flows of the registrant as of, and
for, the periods presented in this report;

4.

The
registrants other certifying officer(s) and I are responsible for establishing
and maintaining disclosure controls and procedures (as defined in Exchange Act
Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

(a) Designed such disclosure
controls and procedures, or caused such disclosure controls and procedures to
be designed under our supervision, to ensure that material information relating
to the registrant, including its consolidated subsidiaries, is made known to us
by others within those entities, particularly during the period in which this
report is being prepared;

(b) Evaluated the
effectiveness of the registrants disclosure controls and procedures and
presented in this report our conclusions about the effectiveness of the
disclosure controls and procedures, as of the end of the period covered by this
report based on such evaluation; and

(c) Disclosed in this report
any change in the registrants internal control over financial reporting that
occurred during the registrants most recent fiscal quarter (the registrants
fourth fiscal quarter in the case of an annual report) that has materially
affected, or is reasonably likely to materially affect, the registrants
internal control over financial reporting; and

5.

The
registrants other certifying officer(s) and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
registrants auditors and the audit committee of the registrants board of
directors (or persons performing the equivalent functions):

(a) All significant
deficiencies and material weaknesses in the design or operation of internal
control over financial reporting which are reasonably likely to adversely
affect the registrants ability to record, process, summarize and report
financial information; and

(b) Any fraud, whether or
not material, that involves management or other employees who have a
significant role in the registrants internal control over financial reporting.
