                  Re: Application for Withdrawal
                      Public Service Enterprise Group Incorporated
                      Registration Statement on Form S-3 (File No. 333-127038)
                      --------------------------------------------------------

Ladies and Gentlemen:

      Pursuant to Rule 477 of Regulation C under the Securities Act of 1933, as
amended (the "Act"), Public Service Enterprise Group Incorporated, a New Jersey
corporation (the "Registrant"), hereby requests that the Registration Statement
on Form S-3 (File No. 333-127038) filed with the Securities and Exchange
Commission on July 29, 2005, together with all exhibits thereto (the
"Registration Statement"), be withdrawn on the grounds that such withdrawal is
consistent with the public interest and the protection of investors as
contemplated by Rule 477. The Registrant is requesting withdrawal of the
Registration Statement because it inadvertently omitted the delaying amendment
required by Rule 473 of Regulation C under the Act and cannot file an amendment
to the Registration Statement to add it at this time because of the
unavailability of certain financial information. The Registrant intends to file
a new Registration Statement when the required financial information is
available. No securities have been sold under the Registration Statement.

      The Registrant requests that all fees paid to the Securities and Exchange
Commission in connection with the filing of the Registration Statement be
credited to the Registrant's account for future use.
