Modern and Efficient
Calpine’s fleet of natural gas-fired plants is among the youngest and cleanest in the country. The average plant age is about 15 years old, and the fleet emits fewer greenhouse gases per megawatt hour generated than any other independent power producer in the United States.
Calpine’s fleet of combined-cycle and cogeneration plants is the nations's largest. Highly efficient combined-cycle plants use both natural gas and steam to produce electricity. Cogeneration plants also produce steam for industrial use.
Safety: A Top Operating Priority
Calpine employees embrace a Safety First culture as evidenced by a low total reportable incident rate.
A safety committee of key top executives and plant personnel from various operating regions leads the charge to continued safety improvement and awareness.
Scale in 3 Major Markets
Calpine’s portfolio has significant scale in three major power markets: Texas, California and the Mid-Atlantic.
With a modern, diverse and flexible fleet of state-of-the-art plants, Calpine is poised to benefit from price and volume improvements in all three areas as the country’s economic recovery strengthens.
Clean and Green
A commitment to environmental excellence in power generation is fundamental to Calpine’s corporate philosophy and culture. While Calpine is one of the nation’s largest producers of electricity, our emissions of sulfur dioxide, nitrogen oxides and carbon dioxide per megawatt hour produced are among the lowest in the industry.
Calpine also operates the largest single renewable geothermal power resource in the world at The Geysers. Steam produced in naturally occurring underground reservoirs is brought to the surface where it drives turbines to produce electricity. Available 24 hours a day, this important renewable resource poses none of the grid integration challenges of other renewables.
Providing meaningful support to the communities where we live and work is an important part of Calpine’s mission. Across the nation, Calpine employees volunteer for Earth Day projects, donate to food banks, run and ride to raise money for medical research, and more.
