Yondr’s Northern Virginia record combines a completed 48 MW building, phased delivery of a second 48 MW building and a separate 240 MW adjacent pipeline. The 336 MW figure is therefore a campus-plus-pipeline ceiling, not live load. Phase-by-phase energization, tenant utilization, contract pricing and any undisclosed financing remain outside the verified public record.
