From Barron's: A BUDDING BULL MARKET IN electric power could give Dynegy a welcome jolt. The Houston-based independent power producer, which narrowly escaped bankruptcy in 2001, doubled its size last year with an acquisition and now boasts 29 power plants in 15 states that generate almost 2,000 megawatts of power. Dynegy's shares, currently at $7 apiece, also look poised to just about double, as the company's cash flow and asset value increase. "Power demand is catching up with supply," says Vance Brown, a principal at money manager Grisanti, Brown & Partners. "Existing power plants are going to be increasingly valuable." Brown estimates that the replacement value of Dynegy's plants could be $15 to $18 a share. The company values those assets at $17 to $24 a share. The shares easily could trade up to 80% of replacement value, which would put the stock at least at $12 if the electricity market tightens, as expected.
