A power plant is like a factory. It takes a raw material and turns it into a product that is valuable to the economy. But unlike most products, power cannot be stored economically on a broad scale – it must be generated as it is needed. Therefore, reliability and flexibility are vital for keeping the lights on at homes and businesses across the nation.

Calpine meets this challenge with a fleet of modern power plants that use clean natural gas as the primary raw material to produce electricity. In addition, we are the nation’s largest producer of geothermal power.
