En fait, 7.65 GW, c'est la capacité maximale pour laquelle le site a reçu une autorisation. Il produirait 1 GW début 2028, et 5 GW en 2031. Si tout va bien, car avec la pénurie actuelle de turbines à gaz de grandes capacités, je ne sais pas ce qu'ils ont réservé dores et déjà auprès des grands fournisseurs (GE Venova, Siemens, Mitsubishi Electric Heavy Industry).
Sinon, il y a les turbines d'avion adaptées, par exemple de celles d'un Boeing 767. 40 MW quand même. Mais c'est moins efficace et plus bruyant.
Il y a un article intéressant (en anglais), à ce sujet, de Mai dernier, sur le site nationalinterest.org, de Fyodor Dimitrenko, un chercheur de Sciences Po Paris :
How a Single Piece of Heavy Machinery Is Reshaping the AI Race
May 4, 2026 - By: Fyodor Dmitrenko
AI’s next bottleneck is power, with turbine shortages and grid constraints reshaping where and how fast data center infrastructure can scale globally.

AI Infrastructure Geography and the Importance of Turbine Access
To host frontier AI compute capacity in 2028 or 2030, a country needed a turbine slot in 2025. Access to a heavy-frame F- or H-class machine has become a determinant of where AI infrastructure can physically be built. Turbines are joining the small list of resources that constrain national strategy: leading-edge semiconductors, high-bandwidth memory, rare-earthrefining, and now the rotating machines that turn heat into electrons.
Washington has begun to recognize this. The Department of Energy’s Speed to Power initiative is designed to accelerate large-scale generation specifically for the AI build-out, and there are credible reports that the Trump administration has examined “whether to pressure allies with outstanding GE turbine orders to release them” for US delivery. Equipment has become a strategic input rather than a commercial good. Saudi Arabia and the United Arab Emirates, both positioning themselves as global AI compute hubs through Public Investment Fund (PIF) and G42-led investments, face the same equipment queue and have begun negotiating directly with manufacturers for priority slots.
Europe is in a more difficult position. Siemens Energy, the European champion, sells most of its US-bound turbines from American factories, and a fresh $1 billion investment is going into US capacity rather than European. The EU data-center build-out, accelerated through European Commission President Ursula von der Leyen‘s €200 billion (approximately $234 billion) InvestAI initiative and France’s €109 billion (about $127 billion) AI infrastructure pledge, runs into the same equipment queue. The European turbine slots that exist tend to be reserved for grid replacement rather than new computing campuses. Europe’s flagship gas turbine maker is, in production terms, increasingly American.

What to Know About Trump's AI Deal
The president said the deal will lower electricity costs, but there are reasons to doubt it will.

What exactly is this pledge?
The “ratepayer protection pledge” signed by Google, Microsoft, Meta, Oracle, xAI, OpenAI and Amazon is meant to ensure residents don’t pay for the electricity used to power data centers. The companies agreed to build, provide or buy any power their data center infrastructure needs.
By having tech companies front these costs, Trump said Wednesday, Americans will avoid increased energy prices — and in fact, these prices could drop “very substantially.”
In turn, Trump said, the government will speed up the process for approving power plants, issuing permits within two to four weeks. However, states — not the federal government — are primarily responsible for approving the development of electricity generation.
