Methodology and provenance
Historical electricity data may be revised after the event.
Physical interconnector flow comes from Elexon INT* observations, not trade or auction allocations. Battery PN is a declared intention, MEL is a declared maximum export limit, and B1610 is a distinct delayed settled observation. Daily constraint costs remain daily context and are never spread across individual minutes or actions.
Calendar selections use a fixed 00:00–12:00 Europe/London window. All indexed events remain available whether or not a public asset location is known. View source health and provenance →
