A connection queue is not a demand forecast.
Ofgem's connection figures describe contracted offers, not the load that will arrive.
Ofgem gives no date for the data centre figure in the consultation or the press release, so it has its own row and is not drawn inside the June 2025 total. Peak demand is Ofgem's remark for scale, not a like-for-like forecast.

Ofgem, Curate: Demand Connections Reform, 29 July 2026, executive summary and paragraphs 2.6 and 2.7. November 2024 and June 2025; data centre reading undated; peak demand 2025 (2025/26 in chapter 2).
