Power has to get there.

Great Britain network evidence covers England, Scotland and Wales, retaining relevant interconnector context.

Day-ahead flow forecasts and published boundary limits are not measured congestion. The Operational Transparency Forum publishes weekly historical and forecast boundary capability, not actual flows.

Historical thermal constraint costs are retrospective GBP figures for published boundary groups, not today’s bill or a complete GB total.

Unused capacity or schedule/output differences are not curtailment measurements. No causal explanation is inferred from coincident changes.
