Constellation and Amazon on Sept. 30 announced a long-term agreement that will support the continued investment in and expansion of the Calvert Cliffs Clean Energy Center, Maryland's only nuclear plant.
The agreement will enable more than $3 billion in Maryland infrastructure investment, including state-of-the-art improvements across the entire 1,790-megawatt plant and approximately 190 megawatts in total of new, emissions-free generating capacity coming online between 2030 and 2032, Constellation said.
The expansion of Calvert Cliffs' generating capacity will be supported by a 20-year agreement, which includes 690 megawatts of power, including the 190 megawatt uprate. The parties have also entered into a related retail supply agreement to support Amazon operations in the 13-state PJM market.
In addition to making the uprate possible, Amazon's long-term commitment will help provide Constellation with the revenue certainty to relicense the plant for another 20 years and make progress toward the development of new clean energy power plants at the site, adding to Maryland’s supply of clean and reliable energy, Constellation said.
The agreement will also help Amazon manage its energy costs for facilities throughout the region. All the electricity generated by Calvert Cliffs will continue flowing to the PJM regional grid just as it does now, demonstrating how large energy users can support investments in new, reliable generation while strengthening the broader electric system, it said.
