- 18 Oct 2026: The 150+ MW figure is AirTrunk's total campus capacity. The campus opened in July 2024, but the share of the 150+ MW that is built and operating is not disclosed. The figure is now a lower bound of design capacity and is excluded from confirmed operating totals. The technical data hall area is also campus design area.Before: 150 MW shown as Operating and included in operating totals.airtrunk.com (opens in a new tab)
