The company’s commitment helps keep the state’s largest source of carbon-free energy running for decades and helps add new capacity to the grid. Amazon is working with Maryland-based Constellation Energy to expand carbon-free nuclear generation at the Calvert Cliffs Clean Energy Center in Calvert County.

Calvert Cliffs produces about 80% of Maryland’s carbon-free energy, enough to power more than 1. 3 million homes. This builds on Amazon’s long-term investment in the state of more than $20 billion since 2010 and supporting more than 33,000 direct and indirect jobs across Maryland.

Amazon launches a carbon credit service, enabling access to high-quality credits for qualified companies Available through the Sustainability Exchange, this service will offer science-based carbon credits to suppliers, business customers, and Climate Pledge signatories.

Amazon’s long-term commitment helps Constellation invest in upgrading the plant, adding 190 megawatts of new carbon-free power—enough to power about 147,000 U. S. homes. That new capacity is expected to come online between 2030 and 2032. The commitment also lays the groundwork to explore next-generation nuclear technology at the site.

The energy Calvert Cliffs produces will keep flowing to the regional grid that serves Maryland and neighboring states just as it does today. The expansion of Calvert Cliffs’ generating capacity will be supported by a long-term agreement, which includes 690 megawatts of power.

Amazon and Constellation have also entered into a related retail supply agreement to support Amazon operations across the PJM market, which manages the electric grid across 13 states and the District of Columbia.

Calvert Cliffs is one of the most reliable sources of carbon-free energy in the region, running around the clock to deliver steady, always-on power. Amazon's long-term commitment helps keep this critical plant running for decades and protects about 850 skilled, well-paying jobs, many of them union jobs that anchor the local economy.

Homegrown innovation supporting Maryland communities Constellation Energy is a Maryland-based company that has operated Calvert Cliffs for decades. Amazon's commitment strengthens Calvert Cliffs as a cornerstone of Maryland's energy and local economy.

It also opens the door to growth: Amazon and Constellation are exploring ways to generate even more carbon-free energy at the site, including new nuclear units. "This agreement demonstrates how private investment can strengthen critical energy infrastructure," said Joe Dominguez, chairman, president, and CEO of Constellation.

"Amazon's commitment supports the long-term operation of Calvert Cliffs for generations to come and creates a strong foundation for future investment in both the facility and in advanced nuclear technologies."

Amazon’s carbon-free energy projects contribute $11 billion to US GDP, support nearly 22,000 jobs in local communities Amazon's solar, wind, nuclear, and battery storage investments drove economic growth across the U. S. from 2023 through 2025, per an Oxford Economics study.
