“Since our founding, Calpine has been a leader in environmental stewardship. As the world moves toward decarbonization and electrification, Calpine’s natural gas and geothermal power plants, as well as our retail platforms, will continue to play a critical role in supporting grid reliability, providing lower-carbon power and meeting our customers’ needs.”

– Thad Hill, Calpine President and CEO

This commitment has resulted in Calpine having one of the lowest carbon intensities of the electricity it delivers to its customers of any power company. Here’s how:

  • Leading the industry in moving to newer, cleaner, natural gas combined-cycle units.
  • Designing plants to use natural gas efficiently to lower the carbon intensity of the electricity we produce.
  • Utilizing a fleet that consumes significantly less fuel to generate power than conventional power plants.
  • Emitting fewer air pollutants compared to coal-fired or oil-fired power plants.
  • Advocating for adoption and implementation of the economy-wide Cap-and-Trade Program and the Regional Greenhouse Gas Initiative program.
  • Promoting state and federal policies to achieve reductions in emissions, including a national price on carbon.

Calpine’s Geysers

We are committed to helping the country reach its clean energy goals by providing clean and affordable energy to Americans across the country.

Our Geysers in California are just one example of us making this commitment a reality.
