SoftBank committed up to €75 billion to build 5 GW of data centres in France on Saturday 30 May, routing the boom's largest European bet at EDF nuclear baseload to skip the grid queue.

Key takeaway

France won the boom's biggest European data-centre bet by offering nuclear power that skips the grid queue.

SoftBank Group committed up to €75 billion to build 5 GW of data-centre capacity in France, announced Saturday 30 May at the Choose France summit hosted by President Macron. Phase one is €45 billion for 3.1 GW by 2031, split across three Hauts-de-France sites: Dunkirk at Loon-Plage, Bosquel, and Bouchain. It is the largest single-operator European data-centre bet of the boom.⁠1

SoftBank, the Japanese technology investor behind much of the global compute build-out, chose France deliberately over Germany, the Netherlands and Britain. The siting answers the same grid wall that froze its rivals elsewhere. At Bouchain, EDF (Electricite de France, the state nuclear utility) is repurposing a former power-plant site so the campus draws nuclear baseload, round-the-clock generation that runs independent of weather, directly from an interconnection point that already exists. There is no separate PPA (a Power Purchase Agreement, the long contract operators usually sign to lock in supply) to negotiate against a years-long queue. At the Port of Dunkirk, Schneider Electric is building an industrial cluster that manufactures the enclosures and power modules on site, folding the supply chain into the campus itself.

This is where capital goes when consent and grid both say no. OpenAI paused its UK Stargate site at Cobalt Park citing a hostile regulatory environment and British industrial power at four times US and Nordic rates. France's reply is to aim compute at an existing nuclear fleet and skip the wait. The bet sits inside a boom that has the four largest hyperscalers spending a combined $725 billion this year; the money is not slowing, only relocating to wherever baseload and consent both clear.

Deep Analysis

In plain English

SoftBank, the Japanese technology investment firm, committed up to €75 billion to build a string of giant data centres in northern France, announced at a French government investment conference on 30 May 2026. The first phase targets €45 billion and 3.1 gigawatts of computing power by 2031 across three sites in a region called Hauts-de-France, near the Belgian border. Data centres need enormous, reliable, affordable power supplies. France's state nuclear company, EDF (Electricite de France), is repurposing an old power station at a place called Bouchain to pipe nuclear electricity directly to SoftBank's campus, bypassing the long queue of companies waiting for grid connections. French electronics giant Schneider Electric is building a factory right next to the data centre at the port of Dunkirk to supply equipment on site. SoftBank chose France in part because the UK, its other option, has electricity costs described by OpenAI as more than four times US rates, and a grid queue that takes years to join.

Deep Analysis
Root Causes

Three simultaneous UK failures and one French structural advantage explain why SoftBank routed €75 billion to France rather than Britain. First, OpenAI's public quantification of UK industrial electricity at more than four times US and Nordic rates established a concrete cost differential that any treasury team evaluating European sites would use as a reference figure.

Second, the Cobalt Park pause demonstrated that even a fully announced UK hyperscale campus can be halted mid-development by grid-queue timing and regulatory uncertainty. Third, NESO's Gate 2 process, while operationally credible, does not offer the supply-certainty that EDF's bilateral nuclear baseload contract provides: Gate 2 offers connection access, not a fixed-price long-term supply agreement.

France's advantage is structural rather than political: EDF's 56-reactor fleet provides roughly 70% of French electricity at near-marginal-cost pricing, and repurposing decommissioned power-station sites gives data-centre operators a unique instrument that no other G7 grid operator can replicate, because no other G7 state has France's combination of nuclear fleet density and available brownfield industrial sites with existing high-voltage infrastructure.

What could happen next?
  • Opportunity

    France has established a replicable model for attracting hyperscale capital: brownfield nuclear repurposing plus bilateral EDF supply contracts. Germany and Poland, both lacking equivalent nuclear fleet density, cannot match this instrument in the current planning window.

    Medium term · Assessed
  • Risk

    SoftBank's EUR 75 billion ceiling is a five-year maximum commitment, not a binding expenditure schedule. EDF repurposing timelines and French permitting delays could compress the Phase 1 3.1 GW target significantly.

    Medium term · Reported
  • Consequence

    Schneider Electric's on-site manufacturing cluster at Dunkirk reduces the supply-chain lead times that typically delay European data-centre commissioning, creating a vertically integrated build model other European operators will study.

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July.
