Generating units

A generating unit has a name, rated output and fuel type. Its state moves among Operating, Standby, Maintenance and Outage. The unit is attached to an operational event, so the team can read the operating context with the unit rather than relying on a separate note. Generation intervals then refer to the unit for output and fuel reporting. This gives the plant team a clear way to distinguish a unit register from time-based production observations.

Plant Operators should use a stable unit name across shifts. Rated capacity is a reference value for checking an entry, not a substitute for measured generation. Fuel type identifies the kind of input; the quantity and unit for each time interval live with the interval. Operations Managers can review units by state when an event interrupts production or a planned maintenance window changes availability.

• Unit register. Keep the name, rated output and fuel type with the selected operating event.
• State review. Read Operating, Standby, Maintenance and Outage on the unit board before changing availability.
• Production context. Open the unit’s generation intervals when a manager asks why output changed.

• Unit identity. Agree the naming convention and check that rated capacity and fuel type describe the equipment actually in service.
• Event association. Select the operational record that explains the unit entry and confirm that it belongs to the intended site.
• State changes. Decide who records the unit state and how the shift team confirms a transition into maintenance or outage.

A plant operator sees a unit move from Operating to Standby during a site event. They identify the operational event, update the unit state and record the later generation interval against the same unit. The manager can then compare its interval output with the time of the event. If a second unit has the same fuel type, its interval remains separate because each interval refers to one unit. The event association provides the site context when staff investigate why output changed. Before recording the next state, the Plant Operator checks the current state and the selected event together. A move from Operating to Standby can precede Maintenance or Outage in the planned operating path. The Operations Manager should ask for the event’s actual start time when comparing a state change with the interval, because an entry made after the shift can otherwise appear to explain an earlier output change.
