According to CEO Bill Spence, ‘The supply segment is undervalued in PPL's share price and we are "committed" to fixing this problem.’ Industry experts say, one possibility is that PPL spins off its power plants. Among PPL Energy Supply's biggest assets is the Susquehanna nuclear power plant. By next year, PPL and Newark-based PSEG are expected to have completed construction of the controversial Susquehanna-Roseland transmission line, which will allow electricity generated at the nuclear power plant to flow across the Delaware Water Gap National Recreation Area into New Jersey, where PSEG operates the state's main electric utility. During a recent conference call, analysts repeatedly asked about PPL Energy Supply. Spence, however, divulged little. "We are looking for the best opportunity we have to create shareholder value," he said. "We don't have a specific timeline. We are being disciplined about the process."
