PSEG POWER ANNOUNCES EXPIRATION OF EARLY PARTICIPATION PERIOD FOR

AND PRICING OF EXCHANGE OFFER

(April 13, 2010—Newark, NJ) – PSEG Power LLC (“PSEG Power”), a wholly-owned subsidiary of Public Service Enterprise Group Incorporated (NYSE: PEG), announced today the expiration of the early participation period in connection with its offer to eligible holders to exchange up to $250,000,000 of its outstanding 7.75% Senior Notes due 2011 (the “old notes”) held by them for its newly-issued 5.125% Senior Notes due 2020 (the “new notes”), fully and unconditionally guaranteed by PSEG Power’s three principal operating subsidiaries (the “subsidiary guarantees”), plus a cash payment, the complete terms and conditions of which are set forth in a confidential offering memorandum dated March 29, 2010 (the “offering memorandum”) and the related letter of transmittal (the “exchange offer”).

As of 5:00 p.m., New York City time, on April 12, 2010 (the “early participation date”), according to Global Bondholder Services Corporation, the exchange agent for the exchange offer, the aggregate principal amount of old notes validly tendered and not withdrawn was $194,796,000.

The “total exchange price” for each $1,000 principal amount of old notes tendered and accepted for exchange by PSEG Power, using a yield of 0.819%, will be $1,066.59, consisting of $266.65 in cash and $801.04 principal amount of new notes, as calculated in accordance with the offering memorandum. The total exchange price is inclusive of an “early participation payment” of $30.00, payable only to eligible holders who validly tendered and who did not validly withdraw their old notes at or prior to the early participation date.

The exchange offer will expire at midnight, New York City time, on April 26, 2010, unless extended (the “expiration date”). Eligible holders who validly tender old notes after the early participation date but at or prior to the expiration date, and whose tenders are accepted for exchange by PSEG Power, will receive the total exchange price minus the early participation payment (the “exchange price”), which will be $1,036.59, consisting of $259.15 in cash and $778.51 principal amount of new notes, as calculated in accordance with the offering memorandum.

Each holder whose old notes are accepted for exchange by PSEG Power will receive a cash payment representing interest, if any, that has accrued from the most recent interest payment date in respect of the old notes up to but not including the settlement date, as adjusted in accordance with the offering memorandum.

Tenders of old notes in the exchange offer may no longer be withdrawn, except where additional withdrawal rights are required by law (as determined by PSEG Power in its sole discretion). Consummation of the exchange offer is subject to a number of conditions, including the absence of certain adverse legal and market developments. If more than $250 million aggregate principal amount of the old notes are validly tendered in the exchange offer, PSEG Power will only accept for exchange old notes in an aggregate principal amount of up to $250 million on a pro rata basis among the tendering holders.

The new notes will constitute a further issuance of, and will form a single series with, the 5.125% Senior Notes due 2020, which we issued on April 5, 2010 in the aggregate principal amount of $250,000,000.

If and when issued, the new notes and the subsidiary guarantees will not have been registered under the Securities Act of 1933 or any state securities laws. The new notes and subsidiary guarantees may not be offered or sold in the United States or to any U.S. persons except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act of 1933 and applicable state securities laws. A registration rights agreement provides for the registration of the new notes (and the subsidiary guarantees).

The exchange offer is only made, and copies of the exchange offer documents will only be made available, to a holder of old notes who has certified in an eligibility letter certain matters to PSEG Power, including its status as a “qualified institutional buyer” as defined in Rule 144A under the Securities Act of 1933 or that it is a person other than a “U.S. person” as defined in Rule 902 under the Securities Act of 1933.

This press release does not constitute an offer or an invitation by PSEG Power to participate in the exchange offer in any jurisdiction in which it is unlawful to make such an offer or solicitation in such jurisdiction.

Public Service Enterprise Group (NYSE:PEG) is a publicly traded diversified energy company with annual revenues of more than $12 billion, and three principal subsidiaries: PSEG Power, Public Service Electric and Gas Company (PSE&G) and PSEG Energy Holdings.
