Series
A confirmed schedule series is one series of your schedules in the scheduling area of the schedule, across delivery days. Itsseries_id stays the same on each delivery day.
An external series is in the schedules of both its scheduling areas, and the Scheduling Area Responsible of each area confirms it separately.
Thus it is a different series in each area.
List Confirmed Schedule Series gives each series with its kind, areas and parties.
One record for each settlement period
List Confirmed Schedules gives a list of records invalues.
Each record is one point of a series: the confirmation for one settlement period.
There is at most one record for each series and settlement period, with the confirmation that is in force.
A settlement period without a record has no confirmation that Engrate has recorded.
volume_wh is the energy over the settlement period in Wh.
Finality
finality is the confirmation finality.
It is intermediate while the confirmation can change, and final when settlement uses it.
Use the filter finality=final to read only the values that settlement uses.
In the Netherlands, TenneT does not state when a confirmation is final, thus each value there is intermediate.
