830 MW Texas Combined-Cycle in Operation

LCG, June 5, 2002--Calpine Corporation, based in San Jose, California, announced that its 830 MW Baytown Energy Center has entered into combined-cycle operations.

The Texas facility, located in Baytown, generates 700 MW under base load and can provide 130 MW additional capacity when demand increases.

The company says its plant results in 96 percent less nitrogen oxide emission, 99 percent less sulfur dioxide emission, and half as much carbon dioxide emission than the Texas average for power plants.

Calpine has a twenty-year contract with chemical company Bayer to provide electricity and steam from the Baytown plant.
