The meter applies TOU pricing per the active rate determined by the
settings held within the TOU switching tables.
On the switch to a TOU rate, the meter will apply the pricing set for that
rate.

Table 10 TOU tariff structure
Where TOU with block pricing is required, the rate switching matrix is used
to specify TOU switching times in combination with block thresholds as
shown in Table 11

Table 11 TOU with block tariff structure.
The meter applies TOU pricing per the active rate determined by the
settings held within the TOU switching tables. In addition, multiple individual
rates can be defined that may have up to 3 block thresholds applied. Each
rate can either have different prices per block, which apply as consumption
on that rate moves through the block thresholds or have a single flat rate.
Example: The following example shows a 2-rate TOU with block tariff.
The tariff provides a higher day price for the first 500 kWh of usage. Night
prices are the same throughout the billing period. This gives a variable rate
per consumption level during the day and a flat rate irrespective of
consumption during the night.
At the start of the billing period, the billing period usage will have been reset
to zero for all rates. To implement this tariff structure, Rate 1 Block 1
threshold should be set to 500 kWh and Rate 1 Block 2 threshold will be set
to a value that effectively equates to infinity. For the first 500 kWh of
consumption during the day, Rate 1 Block 1 pricing of 20 p per unit is
applied. Once 500 kWh of usage at Rate 1 is exceeded, Rate 1 Block 2
pricing will be applied. In the example below, the price reduces from 20
pence to 10 pence as Rate 1 Block 1 threshold of 500 kWh is passed.
