Constellation Energy (CEG) saw its stock surge nearly 5% on Wednesday, benefiting from the signing of a U.S.-Saudi nuclear cooperation agreement and new domestic power plant development plans. As the largest nuclear power operator in the United States, the company is not directly involved in the aforementioned projects. However, its industry-leading position, long-term power supply agreement with Microsoft, and recent merger and acquisition expansion have enabled it to continue reaping benefits amid favorable nuclear policy developments, with a positive industry outlook.
The U.S. government announced on Wednesday that it had signed a long-term agreement with Saudi Arabia to jointly advance nuclear technology development. This 30-year agreement formally establishes a cooperative framework between the two countries in the nuclear energy sector and creates conditions for multiple U.S. energy companies to play leading roles in nuclear power construction projects within this strategic Middle Eastern nation. Although Constellation, as the leading U.S. domestic nuclear power operator, is not expected to participate directly in the primary engineering and construction of Saudi projects, its professional expertise in nuclear plant operations positions it to potentially engage in an advisory or training capacity. More importantly, the finalization of this agreement further signals the U.S. government’s active support for the nuclear energy industry.
As the largest nuclear power operator in the United States, Constellation Energy leads its peers with a generating capacity of 60 gigawatts (GW), while its competitor Vistra (VST) ranks second with 44 GW of capacity. In September 2024, Constellation signed a 20-year power purchase agreement with Microsoft (MSFT), planning to commence operations at the Crane Clean Energy Center (formerly the Three Mile Island nuclear plant) in 2027 to supply 835 megawatts of electricity to Microsoft’s data centers. Additionally, the company plans to incorporate the Clinton Clean Energy Center (1.1 GW) into its supply system, a facility that has been subsidized by Illinois taxpayers due to suboptimal economic performance. In early 2026, Constellation completed its $26.6 billion acquisition of Calpine, further solidifying its position as a clean energy leader. Following the acquisition, the company’s total installed capacity approached 60 GW, with expected earnings per share growth exceeding 20% and approximately $2 billion in additional annual free cash flow.
On the domestic policy front, according to Bloomberg, the U.S. government is planning to launch a new project valued at $200 million to support domestic power plant construction, with a focus on meeting the growing electricity demand of artificial intelligence data centers. Nuclear energy, given its clean and stable characteristics, is regarded as an ideal power source. The report, citing relevant documents, indicates that Oklo and X-Energy, both small modular reactor technology firms, will participate in the project as representatives of the energy industry, while Microsoft and Nvidia will join as technology sector partners. Although Constellation is not listed among the project participants, as it operates large-scale nuclear plants rather than small modular reactors, analysts believe that this top-down energy capacity expansion initiative will still benefit the company.
In summary, Constellation Energy, leveraging its absolute scale advantage in the nuclear power sector, long-term power supply agreements with technology giants, and capacity expansion through mergers and acquisitions, has secured a favorable competitive position within the industry. Despite not being directly involved in certain emerging projects, the U.S. government’s strong push for nuclear energy development continues to provide sustained tailwinds for the company, both from a policy direction and industry sentiment perspective.
