a) TOU:
Up to 48 TOU registers can be assigned allowing a different TOU register to be used every half hour.

Time of use (TOU) tariff registers
Users are charged different tariff prices at different times of the day. An example is shown below:
Liberty 100 meters supports configuration of TOU tariff structure for 4 seasons, 4 weeks, 17 days, 12 switching
points per day and 50 special dates.
Block tariff registers
Users are charged different tariff prices for different predefined kWh unit blocks of electricity. An example is
shown below for four block rates throughout a year:
Hybrid tariff registers
Users are charged different tariff prices at different times of the day and for different predefined kWh unit blocks
of electricity. An example is shown below for a hybrid tariff having two TOU rates and two Block rates
throughout a year:
TOU2 (Day)
Block 1 (below the configured threshold)
Block 2 (above the configured threshold)
Note: The above time patterns and thresholds are used as example for this manual. R1 – R4 are different rate
prices in pence.
