INSIGHTS

Updated October 2026Grid connection timelines in France depend on the connection document held (exploratory study, accepted PTF or signed agreement), the works RTE must carry out and their permits. They are site-specific and often run to several years. See our grid connection glossary and which document actually secures a site.

Data-driven analysis of AI data center power infrastructure — grid connections, transformer lead times, brownfield sites, deployment timelines. Updated monthly.

GridReadiness Insights are short, data-driven briefs on AI data center infrastructure in France and Europe: grid capacity and connection timelines, power transformer and switchgear lead times, brownfield sites, power availability by region, and how Europe compares with the United States. They are written for developers, investors and lenders who need the facts behind a site decision. Grid connection timelines in France are site-specific and often run to several years; for the procedure itself, see our grid connection glossary and which grid document actually secures a site. For equipment, start with power transformer lead times in 2026.
