CEG rebounds as Amazon backs a $3 billion Calvert Cliffs nuclear expansion plan.
Amazon signs a 20-year deal supporting 690 MW of power from Calvert Cliffs.
The project will add about 190 MW of emissions-free capacity by 2032 in Maryland.
Constellation plans major upgrades and another 20 years of plant operations.
Calvert Cliffs supplies about 80% of Maryland’s clean electricity each year.

Constellation Energy Corporation shares rebounded 3.14% to $262.00 in pre-market trading after closing 3.99% lower at $254.02. The recovery followed a major nuclear energy agreement between Constellation and Amazon. The companies plan more than $3 billion in infrastructure investment at Maryland’s Calvert Cliffs nuclear facility.

Amazon Agreement Supports Calvert Cliffs Expansion

Constellation and Amazon signed a long-term agreement supporting continued investment in the Calvert Cliffs Clean Energy Center. The Maryland facility currently operates with 1,790 megawatts of nuclear generating capacity. Planned upgrades will add about 190 megawatts of emissions-free generation between 2030 and 2032.

The expansion forms part of a 20-year agreement covering 690 megawatts of electricity from the facility. That total includes the planned 190-megawatt increase in generation capacity. Amazon also signed a related electricity supply agreement covering its operations across the 13-state PJM market.

The arrangement gives Constellation long-term revenue support for upgrades and continued plant operations. Constellation also plans to pursue another 20-year operating license for the nuclear facility. Meanwhile, the agreement could support development of additional clean-energy facilities at the Calvert Cliffs site.

Amazon Strengthens Long-Term Nuclear Energy Supply

Amazon will use the arrangement to support electricity needs across its regional facilities. However, Calvert Cliffs will continue supplying all generated electricity directly into the wider PJM regional grid. The structure allows Amazon to support new generation capacity without removing electricity from regional power markets.

The agreement also gives Amazon greater visibility over long-term energy costs across the region. At the same time, the commitment provides Constellation with predictable revenue for major infrastructure spending. Both companies aim to increase reliable carbon-free electricity while supporting broader power grid requirements.

Large technology companies have increased their focus on nuclear energy as electricity demand rises from data centers. Nuclear facilities provide continuous electricity generation without direct carbon emissions during operations. As a result, long-term power agreements can support both data-center growth and nuclear infrastructure investment.

Calvert Cliffs Remains Central to Maryland Energy

Calvert Cliffs sits in Lusby along the western shore of Maryland’s Chesapeake Bay. The nuclear facility produces about 80% of the state’s clean electricity. Its annual electricity output can supply the equivalent power needs of more than 1.3 million homes.

The facility currently employs more than 800 workers across its operations. It also contributes about $21 million annually through taxes supporting public services. Those payments help fund schools, roads and other local infrastructure around the plant.

The planned investment will modernize equipment across both generating units while increasing the facility’s overall production capacity. Constellation expects the project to strengthen the plant’s long-term role within Maryland’s electricity system. Amazon’s commitment also creates financial support for potential advanced nuclear development at the same location.
