Calpine Corporation products

Simple-cycle plants are the most flexible and operate as quick-responding "peakers" that generate power when demand is highest.

Combined-cycle plants integrate natural-gas-fired and steam turbines, are more efficient than simple-cycle plants and generate the most megawatts produced by Calpine`s fleet.

Cogeneration plants add another degree of efficiency by also supplying steam to nearby customers for industrial processing or heating. Calpine operates the nation’s largest fleet of cogeneration facilities – also called combined heat and power plants.

Geothermal power plants take advantage of high temperatures deep underground to generate steam for clean, sustainable power.
