RALPH IZZO ELECTED PRESIDENT AND CHIEF OPERATING OFFICER OF PSEG;
RALPH LAROSSA NAMED PSE&G’S PRESIDENT AND CHIEF OPERATING OFFICER

Izzo Positioned To Become Chief Executive Officer
Upon Retirement of E. James Ferland in 2007

Public Service Enterprise Group (PSEG) today announced the election of Ralph Izzo as president and chief operating officer of the company and also as a member of the Board of Directors. This action by the Board is effective October 1, 2006 and positions Izzo to become chief executive officer upon the retirement of E. James Ferland, now planned for March 31, 2007.

The Board also elected Ralph LaRossa to succeed Izzo as president and chief operating officer of PSEG’s utility business, Public Service Electric and Gas Company (PSE&G), also effective immediately. LaRossa has been PSE&G’s vice president-electric delivery.

“The Board’s choice of Ralph Izzo and Ralph LaRossa to guide PSEG and PSE&G in the ever-changing energy business environment is a tribute to their wealth of knowledge, vast experience, hard work and depth of leadership capabilities,” said Ferland, who is relinquishing his post as president of PSEG. “Both are well-liked and well-respected in and out of the company. I could not be happier for both of them, and I am confident they will do an excellent job for our shareholders, customers, employees and the communities we serve.”

Ferland said the timing of the appointments well in advance of his departure allows the company ample opportunity for a smooth transition in executive leadership. “Over the next few months Ralph Izzo, Ralph LaRossa and other senior leaders will be updating our long-term strategic business plan that will further support PSEG’s strong outlook for 2007,” Ferland said. Last week, PSEG projected 2007 earnings in the range of $4.60 to $5.00 per share, about 30% higher than earnings of $3.45 to $3.75 anticipated for this year.

Reacting to his new responsibilities, Izzo, 48, said: “This is an extraordinary honor. I thoroughly appreciate the trust that Jim Ferland and the Board have placed in me. I look forward to working with the dedicated men and women of PSEG to make our strong company even stronger. I will do this always with a close eye on maintaining our commitment to shareholder value, safe and reliable service and the highest levels of corporate citizenship.”

LaRossa, 43, echoed Izzo’s sentiments. “The challenges facing PSE&G in the safe and reliable delivery of electricity and natural gas to more than 2.2 million customers in New Jersey are enormous. But, I am extremely pleased to be given the opportunity to take on these challenges along with a superb work force. I thank Jim, Ralph and the Board for their confidence in me.”

Ferland, 64, will be retiring from PSEG after more than 20 years as chairman, president and chief executive officer of PSEG. He currently has the distinction of being the longest-serving chief executive at
