6.7.5. Indexes
The contractually specified tariffs define the energy and demand rates being used by the meter. However, in
many cases, active energy has more rates defined (for billing purposes) than reactive energy.
An index describes a combination of energy and demand rates that are activated simultaneously.
The meter index structure provides a mechanism to manage:
 up to fifty different rate switching schemes for active and reactive energy
 any overlapping rates for demand
 the activation of any assigned control outputs
Note: The energy (45) and demand ( 48) channels must already be defined in the meter before indexes can be
configured and the required control outputs must be assigned to index use.
6.7.5.1. Index activation
Indexes can be activated as follows:
 Immediately
The rate change is applied immediately as defined in the calendar day profile.
 Delayed
The rate change is delayed until the end of any running demand calculation integration period ( 49).
 Clock Loss
When a clock loss event is detected (backup power supply ( 39) sources exhausted), the meter will switch to
a pre-configured index with a low tariff rate to ensure the customer is not penalised during this period.
