A rolling 24 hours ending at the current quarter-hour, sliding as it refreshes. Solar segments are what each dwelling consumed from generation plus what was exported; grid segments are what each imported and will be billed for.

Each day is priced interval by interval at the rate that applied at the time, so solar used during an expensive band is worth more than the same kilowatt-hour at midday. This is an estimate from our own meters and the plan's own rates — it is not a bill, and nobody is charged from it.

Every quarter-hour of a week, coloured by the window it resolves to. Any Unmatched cell means an interval that would fall through — add a catch-all window at priority 0.

Static Web Apps decides who someone is; this decides what they may do. Grant a role from Role management in the Azure portal, then set what it can reach here. Data scope limits whose figures they see — a house tenant sees the house and the shared site totals, not the flat's usage.

A day short of its full interval count has a gap. Bills covering flagged intervals are still produced, but the shortfall is reported alongside them — never issue one without reading the warnings.
