Calpine Backs Cheng
Calpine Corp. has announced a $2 million investment in Cheng Power Systems Inc., developer of Advanced Cheng Cycle technology.
The technology is a specialized steam injection system that recycles steam created by a gas turbine`s exhaust heat to increase power plant output and efficiency. The system is now being applied to mid-sized gas turbines from 50 MW to 125 MW. Calpine`s investment, structured as a two-year loan, will help fund testing and will augment the company`s 6,300 MW development program.
The technology was first applied in 1983 at San Jose State University`s power plant, and has since been installed at more than 50 sites worldwide. p
