Generation intervals

A generation interval belongs to one generating unit and carries a start time, end time, energy output, fuel quantity and fuel unit. The paired boundaries matter: a quantity without its period cannot explain when production happened. Keep both output and fuel on the same interval so managers can inspect the operating pattern of a unit during a particular event. The timeline makes the sequence visible without turning every interval into a sitewide total.

The unit link supplies equipment context and, through its operational event, the event context. A plant operator should check the selected unit before recording values for a shift. Operations Managers can read fuel consumption alongside output, while retaining the source units of measure. A reviewer looking across periods can identify overlaps or gaps for follow-up. The record itself stores the reported quantities; it is not a live control signal.

• Unit selection. Choose the generating unit before recording the period and its measured output.
• Paired quantities. Keep energy output, fuel quantity and fuel unit on the same interval.
• Boundary review. Compare adjacent starts and ends for one unit before interpreting the timeline.

• Time boundaries. Agree how shift handover times are recorded and which timezone is used for comparisons.
• Measurement units. Use the output and fuel units consistently so the same report does not add unlike quantities.
• Unit selection. Confirm each period belongs to the intended generating unit before using it in a report.

At a shift change, the Plant Operator records an interval ending when the next shift begins. The interval names the generating unit and includes its energy output and the fuel quantity with its fuel unit. The Operations Manager compares the interval with the unit state and the associated operational event. If the same period is entered again under a different unit, staff should inspect the unit link and source measurements before interpreting a combined report. The timeline helps show which period came first and whether a boundary needs correction. At the next handover, the operator compares the new start with the prior end for that unit. If they overlap, the manager checks the source observation before using either period in a report. A fuel quantity has meaning only with its fuel unit; keep both visible beside the energy output. The event associated with the unit supplies context, while the interval remains the source for measured production.
