America’s Premier Competitive Power Company
... Creating Power for a Sustainable Future


Right Fleet, Right Place, Right Time

Advantage Guadalupe Name

An evolution is underway in America’s power markets, driven by several key factors:

  • The abundance of domestic shale natural gas is expected to keep prices low for the foreseeable future.
  • Regulations to protect the future of the planet have been enacted by federal and state agencies. 
  • Electrical system operators are increasingly focused on compensating generators based on operating performance to ensure transmission grid reliability.

In this environment, Calpine’s modern fleet stands uniquely well-positioned to benefit from the secular trends that are moving America toward clean, affordable natural gas as the preferred fuel of power generation.


Environmental stewardship is fundamental to Calpine’s philosophy and culture. Generating power in a sustainable and environmentally responsible manner not only positions our business to benefit from the regulatory trends that are shaping the nation’s power generation industry, it is simply the right thing to do – for our communities, employees and future generations.
