SoftBank intends to collaborate through its SB Energy division and join forces with French industrial engineering leader Schneider Electric to create an expansive industrial manufacturing complex in Dunkirk. The complete initiative aims for 5 GW of total capacity throughout France. Son highlighted France’s electrical grid capabilities, available industrial real estate, and skilled engineering workforce as primary factors driving the selection. France’s power infrastructure — predominantly nuclear-based — delivers reduced carbon emissions and more predictable energy expenses versus other European markets. Roland Lescure, France’s economy and digital sovereignty minister, characterized it as evidence of France’s “fast access to the most reliable electrical grid in Europe.” EDF chairman Bernard Fontana noted the initiative would transform previously used industrial locations while advancing France’s digital infrastructure objectives. This consideration carries weight because electricity expenses have emerged as among the most significant obstacles to AI data center expansion throughout Europe. Escalating energy costs — partially connected to U.S.-Iran geopolitical tensions — have complicated large-scale computing investments across the region. SoftBank’s French commitment extends its wider artificial intelligence infrastructure strategy, which has already gained momentum domestically in the United States. The corporation has deployed over $30 billion into OpenAI, recording $45 billion in valuation appreciation from that holding during the fiscal year concluding in March. Its ownership position in Arm Holdings, whose semiconductor architectures enable Nvidia-powered AI servers, maintains its direct connection to the foundational infrastructure supporting the AI expansion. SoftBank indicated the French data facilities will accommodate AI developers, cloud service operators, corporate clients, government agencies, and academic research entities. The company additionally intends to engage with regional universities and technical institutions to facilitate talent pipeline development. SoftBank surpassed Toyota to claim the position of Japan’s highest-valued corporation by market capitalization earlier this year, based on FactSet information. The Choose France conference serves to draw international capital, and this week’s declarations have secured pledges from approximately 100 organizations, per the French presidential office.
