In a move that underscores the renaissance of nuclear power as the backbone of the digital future, Meta and Constellation announced June 3 a landmark agreement to secure 1,121 megawatts of emission-free power from the Clinton Clean Energy Center plant in Illinois. The 20-year contract will enable Meta to advance its sustainability goals and, most importantly, ensure reliable power supply for its expansion in artificial intelligence.

The agreement goes into effect in June 2027, just as the state's Zero Emissions Credit (ZEC) program, which has subsidized the Clinton operation since its closure was averted in 2017, expires. Unlike the ZEC, the new contract is a market-based solution that replaces the public subsidy with private investment, thus ensuring the viability of the energy center without burdening ratepayers.

A key plant

The Clinton Clean Energy Center, one of the most efficient reactors in Illinois, was on the verge of closure due to financial losses despite its excellent performance. Now, thanks to this agreement, it plans not only to maintain but to increase its capacity by 30 megawatts through technical improvements.

The plant generates enough electricity to supply more than 800,000 homes, directly employs more than 530 people, and contributes US$13.5 million annually in taxes. In addition, its operation avoids the emission of millions of tons of carbon: according to a study by The Brattle Group, its closure would have meant more than 34 million additional tons of CO₂ over two decades.

Artificial intelligence needs reliable energy

Urvi Parekh, head of global energy at Meta, was clear: "Ensuring clean and reliable energy is necessary to advance our AI ambitions." This statement encapsulates a new reality: artificial intelligence - and digital infrastructure in general - depends on a robust, stable and disruption-free energy base. With the signing of the contract, Meta becomes a leading player in sustaining a traditional but vital energy source that has gained renewed public support. According to Gallup, support for nuclear power in the U.S. grew to 61% in 2025, up from 55% the previous year.

Joe Dominguez, CEO of Constellation, used the occasion to launch a reflection that goes beyond business: "Sometimes, the most important part of our path forward is to stop going backwards". For him, this agreement not only preserves jobs, but also enhances the value of existing infrastructure, at a time when the country is debating new energy sources and security of supply.

Local impact and future projections

The Clinton plant will not only continue to operate, but will also become a platform for new developments. Constellation is evaluating the possibility of extending its site license or even obtaining a new permit to build an advanced nuclear reactor or a modular nuclear reactor (SMR) at the same location. These projects, if realized, could put Illinois at the forefront of next-generation nuclear power.

Locally, the deal has been greeted with enthusiasm by authorities and labor organizations. More than 1,100 quality jobs will be preserved and a social investment of $1 million over five years will be secured for education, social services and job development programs in the community.

Helen Michelassi, mayor of Clinton, summed it up, "While other communities are losing jobs and income, Meta is investing in our future."
