About Yondr London Campus Building 3

Yondr London Campus Building 3 is a separately tracked building within Yondr’s Wexham Road campus. The three-building program totals just over 100 MW: 30 MW Building 1, 30 MW Building 2 and 40 MW Building 3. Shared-campus permits and infrastructure do not turn the combined total into this building’s capacity. Phase-by-phase energization, tenant utilization, contract pricing and any undisclosed financing remain outside the verified public record.
