EXHIBIT 99.1 September 30, 1999 For information, contact: Conectiv: Mary Rucci, (302) 429-3334 PSEG Power: Kathy Ellis (973) 430-6618 PECO: Bill Jones (215) 841-4129 CONECTIV TO SELL INTERESTS IN NUCLEAR PLANTS TO PSEG POWER AND PECO ENERGY Wilmington, De. - Conectiv (NYSE:CIV), an energy and vital services provider serving the Mid-Atlantic region, today announced it has reached agreements to sell ownership interests in three nuclear plants to PSEG Power LLC (PSEG Power) and PECO Energy Company (PECO). The ownership interests will be sold for approximately $20 million, plus reimbursement of actual fuel inventory at closing, subject to receipt of various federal and state regulatory approvals. All of Conectiv's nuclear interests will be sold as a result of the agreements: o A 15-percent interest (328 megawatts) in the Peach Bottom Atomic Power Station Units 2 and 3 will be sold in equal shares to co-owners PSEG and PECO, each of which presently owns about 43%. PECO is the operator of that facility. o A 14.8-percent interest (328 megawatts) in the Salem Nuclear Generation Station Units 1 and 2 will be sold to PSEG Power, a subsidiary of Public Service Enterprise Group Incorporated (PSEG), which presently owns about 43% interest in and is operator of that facility. o A five-percent interest (52 megawatts) in the Hope Creek Nuclear Generating Station also will be sold to PSEG Power. PSEG presently owns the other 95 percent of Hope Creek and operates the facility. According to the agreements, PSEG Power and PECO will assume full responsibility for the ultimate decommissioning of Peach Bottom, Salem and Hope Creek. The sales are expected to close by mid-2000. "This sale moves Conectiv closer to its goal of focusing on a mid-merit generation strategy," said Tom Shaw, Executive Vice President of Energy Supply, who noted that the electricity produced from the three stations will continue to be available for customers in the region that the companies serve. Shaw continued, "A long-term benefit of these sales to Conectiv is reducing the financial risk associated with a minority ownership in nuclear plants. As the industry restructures, larger utilities strategically focused on nuclear generation will be better positioned to assume these risks." Shaw noted that in keeping with its mid-merit generation strategy, Conectiv plans to announce the buyers of its baseload fossil fuel plants later this year. Conectiv is developing a generation portfolio of mid-merit plants that are able to follow the market peaks, he noted, and recently announced its plans to build a new 500-megawatt combustion turbine/combined cycle plant at its Hay Road/Edge Moor complex in New Castle County, Delaware. "This is one in a series of growth steps on the road to further positioning PSEG Power as a player in the regional energy market," said Frank Cassidy, president PSEG Power "The opportunities are out there and, as we did in this case, we intend to evaluate and acquire additional generation that enhances our portfolio and adds value to our bottom line." Jerry Rainey, president of PECO Nuclear, said the purchase of 7.5 percent ownership of Peach Bottom, bringing PECO Energy's ownership share to 50 percent, fits well with the company's strategic business objective to increase its nuclear generation portfolio. "Peach Bottom is an excellent, high capacity plant," Rainey said. "We welcome ownership of the additional energy from the facility."
