Following the acquisition, Constellation will serve more than 2.5 million customers, making it the largest competitive retail electricity supplier in the US.
Introducing Calpine
Calpine is the largest generator of electricity from natural gas and geothermal resources in the US.
The company, based in Houston, serves customers in 24 states, as well as in Canada and Mexico.
Its 76 power plants — including those under construction — make up more than 25,000MW of generation capacity.
Calpine’s The Geysers, located in the Mayacamas Mountains north of San Francisco, is the world's largest complex of geothermal power plants.
Comprising 18 power plants spread across 45 square miles along the Sonoma and Lake County border, this geothermal field harnesses naturally occurring steam reservoirs below the earth's surface. The Geysers generates approximately 725MW of clean, renewable electricity — enough to power 725,000 homes or a city the size of San Francisco.
Andrew Novotny, President and CEO of Calpine, says: “This is an incredible opportunity to bring together top tier generation fleets, leading retail customer businesses and the best people in our industry to help drive a stronger American economy for a cleaner, healthier and more sustainable future.

What Constellation’s acquisition of Calpine means for energy procurement
So, what’s the significance of the deal?
As well as creating the US’ largest competitive retail electricity supplier, Constellation’s acquisition of Calpine could transform energy procurement in a number of ways.
The merger also creates the largest clean energy provider in the US, offering businesses and governments substantially expanded options for procuring reliable and sustainable electricity.
What's more, the combined entity will become the nation’s leading competitive retail electric supplier.
It means businesses will benefit from an unprecedented portfolio that includes nuclear, natural gas, geothermal, hydro, wind, solar and battery storage capabilities, allowing them to meet increasingly complex sustainability goals by providing a broader range of clean energy products.
For example, Calpine's aforementioned extensive gas plant infrastructure will ensure grid reliability during the ongoing transition to renewable energy sources — something that’s = crucial for procurement planning.
Joe adds: “By combining Constellation’s unmatched expertise in zero-emission nuclear energy with Calpine’s industry-leading, best-in-class, low-carbon natural gas and geothermal generation fleets, we will be able to offer the broadest array of energy products and services available in the industry.
“Both companies have been at the forefront of America’s transition to cleaner, more reliable and secure energy, and those shared values will guide us as we pursue investments in new and existing clean technologies to meet rising demand.
“What makes this combination even more special is it brings together two world-class teams, with the most talented women and men in the industry, who share a noble passion for safety, sustainability, operational excellence and helping America’s families, businesses and communities thrive and grow. We look forward to welcoming the Calpine team upon closing of this transaction.”
