Emissions Performance

Aging fossil-fueled power plants are a major source of air pollution and greenhouse gas emissions. Many plants in the United States are 30 to 35 years old and are not equipped with the newest air emission control systems. Calpine's modern fleet uses highly efficient turbines and the most modern emissions control technology to help protect the environment while producing reliable, low-cost electricity.

Plants using modern emissions control technology consistently outperform conventional fossil-fueled plants in curbing the emissions that contribute to ground-level ozone/smog (nitrogen oxide), greenhouse gases (carbon dioxide) and acid rain (sulfur dioxide). By using natural gas-fired combined-cycle and geothermal technologies, Calpine powers homes and industry while conserving precious natural resources. While Calpine is one of the nation’s largest producers of electricity, our emission rates for these pollutants per megawatt hour produced are among the lowest in the industry.
