Amazon and Constellation Energy have finalized a 20-year power purchase agreement aimed at expanding and improving Maryland’s Calvert Cliffs Clean Energy Center, the state's largest source of clean energy. The agreement, announced Wednesday, will facilitate over $3 billion in infrastructure investments within Maryland, including upgrades to the 1,790-megawatt Calvert Cliffs facility. The project anticipates the

Tech giants are aggressively pursuing nuclear power solutions. Talen Energy recently finalized an agreement with Amazon to provide up to 1.9 gigawatts of nuclear power, a substantial amount intended to fuel Amazon’s data center operations. The collaboration also includes investigating the potential for deploying small modular reactors (SMRs) at Talen’s Pennsylvania facility. Amazon’s commitment extends beyond this single deal. They've invested heavily in reactor designer X‑energy, securing a $500 million investment, and have established partnerships with Dominion Energy and Energy Northwest to develop over 600 megawatts of SMR capacity, with plans to reach 5 gigawatts by 2039. Furthermore, the Susquehanna facility will transition to a "front-of-the-meter" structure, utilizing the PJM grid. This strategic push for nuclear energy, often referred to as the “Amazon Helios Project” by investors, is driven by the need for a clean and scalable power source to support burgeoning data centers and artificial intelligence infrastructure. Microsoft has also entered the space with a fusion power purchase agreement with Helion Energy, aiming for 50 megawatts within the coming years. AWS is leveraging AI to improve plasma physics simulations, highlighting the intersection of technology and energy innovation. The announcement spurred an 8% increase in Talen Energy's stock price. This development signals the emergence of a new investment sector: fully contracted, utility-scale nuclear energy specifically designated for hyperscale computing needs. Achieving ambitious net-zero goals is difficult without substantial changes in energy sources, and fusion power offers a potential pathway to meet the increasing power demands of advanced computing while minimizing environmental impact.
