CHN-1 is the first of two Ambattur buildings, designed for 23.2 MW across eight data halls and phased service during 2026. It shares a 68 MVA main feed and campus substation with CHN-2, but the 42 MW campus total is not assigned to CHN-1 or presented as operating IT before commissioning. Customer utilization, private contract terms and unreported project financing remain outside the verified public record.
