Calpine Cuts Plant Development In 2002

LCG, Jan. 16, 2002--Calpine Corp. announced that it will not proceed this year with 34 power projects that have reached advanced-stage development, while 27 projects now under construction will move towards completion.

By curtailing the projects, the San Jose, Ca.-based company will wait for market prices to recover, and manage its debt load. The move reduces planned capital spending by nearly $2 billion, according to Calpine.

When market conditions improve, Calpine plans to expand its generation portfolio. "While 2002 will be a challenging year for the entire power industry, we believe the underlying, long-term growth in electricity demand, the historic swiftness with which power demand recovers in the wake of a recession, and the recent decisions by many of our competitors to curtail new plant construction wil all work to Calpine's favor," the company said.

Rating agencies Moody's and Standard & Poor's have considered the company to have an unfavorably high level of debt, and had rated its bonds below investment-grade in December of last year.
