Tariff Features
7.8 Climate Change levy
E470 Tokenless Smart Prepayment Meter
Issue: 1.8
To enable the meter to be used against commercial tariffs it must be able to
cope with the UK Climate Change Levy (CCL). At present the levy is
applied to customers using over 3000 kWh's per quarter year (~33kWh per
day). In addition to the levy higher rate VAT is applied to usage above this
value.
The meter will hold a CCL charge value between 0.000 and 99.999
pence/kWh (present CCL charge 0.456 pence/kWh).
The meter will also hold two VAT values, VAT rate 1 and Vat rate 2. VAT
rate 1 will be used to define the level of VAT already applied to the normal
tariff prices within the tariff table. VAT rate 2 will hold the higher rate value.
The meter is capable of applying CCL and VAT rate 2 to usage above a
configurable daily de-minimis value. The meter will hold values for both
CCL and VAT 2 application. This will ensure future proofing in case future
CCL and VAT application thresholds no longer coincided.
The meter records the monetary amount of charges taken from the Present
Balance register from the start of the billing period. This is used for
reconciliation purposes at the end of the billing period.
At 00:00, following a day's usage, the meter will calculate an average daily
usage value using the total registered kWh's from the start of the billing
period and the number of days lapsed.
If the calculated average daily amount is greater than the de-minimis value
for CCL then the following day, the CCL charge will be applied to each kWh
consumed.
If the calculated average daily amount is greater the de-minimis value for
VAT rate 2 then the difference between VAT rate 1 and VAT rate 2 will be
applied to each kWh consumed.
At the end of the billing period the monetary amount taken over the period
will be stored together with a time stamp and the working value reset.
At the end of the billing period the meter will be reconciled against a billing
read raised in the suppliers system. The system will require meter readings
and monetary charges raised during the billing period and stored within the
meter. Where a discrepancy occurs between billing and meter values a
credit adjust value will be applied.
