BGX701-075-R03
All snapshots have a date and time stamp, snapshot reason and the last billing date and time. Snapshot data is
available for all configured energy types.
4.2.5.1
Midnight Snapshot
Premier 211 takes a daily snapshot of the energy registers at each midnight and stores the data for the last 14
days. The snapshot data is updated daily on an FIFO basis.
The meter does not record midnight snapshots for days when power was off for the complete day. For example,
if the meter power was off at 11:45 PM on Monday and resumed at 10.00AM on Wednesday, the midnight
snapshot is logged only for Wednesday and not Tuesday.

●

The meter stores a total of thirteen (13) billing snapshots. Billing snapshot data is updated on a FIFO basis.
On change of tariff and meter operating mode, a billing snapshot is performed before the event.
a) Change of tariff – the meter takes a billing snapshot before activation of a new tariff configuration.
Change of tariff comprises the following:
•
Change of tariff scheme
•
Tariff type
•
TOU seasonal calendar
b) Price change – the meter takes a billing snapshot whenever the prices are revised or changed.
c) Scheduled billing date – the meter takes a billing snapshot on the scheduled billing date. The billing
period can be configured in days, weeks or months. If the meter is in a power OFF state at the
scheduled billing time then it will take the snapshot when power is resumed, this will not affect the next
billing date.
d) On-demand billing – the meter takes a billing snapshot on receipt of a request for an on-demand bill.
The snapshot data recording will depend on the billing reference which can be configured either as
immediate or at midnight. If the billing reference is configured for midnight, then the previous midnight
snapshot is taken as the billing snapshot.
e) Change of meter operating mode – a billing snapshot is taken when the meter’s operating mode is
changed from Credit to Default or vice versa.
f) Change of Supplier –on change of supplier the meter performs a billing action and a billing snapshot is
taken before the change of supplier and a second snapshot is taken after the change has taken place (if
configured).
g) Change of Tenancy – on change of tenancy the meter performs a billing action and a billing snapshot is
taken before the change of tenancy and a second snapshot is taken after the change has taken place (if
