PART 1Information to be provided by relevant suppliers to the Authority
1. The mean annual household electricity consumption in the scheme year of all domestic customers supplied by the relevant supplier with electricity at a discounted tariff.
2. The mean annual household gas consumption in the scheme year of all domestic customers supplied by the relevant supplier with gas at a discounted tariff.
3. For each combination of fuel type and payment method—
(a)the number of customers supplied at a discounted tariff (“discounted tariff customers”) on the last day of each month in the scheme year;
(b)unless sub-paragraph (d) applies, the price of the discounted tariff on the last day of each month in the scheme year;
(c)unless sub-paragraph (e) applies, the price of the reference tariff on the last day of each month in the scheme year;
(d)if the supplier charges different prices in different regions for the discounted tariff, the mean, on the last day of each month in the scheme year, of the prices of the discounted tariff in each region in which the supplier has customers on that tariff, and
(e)if the supplier charges different prices in different regions for the reference tariff, the mean, on the last day of each month in the scheme year, of the prices of the reference tariff in each region in which the supplier has customers on that tariff.
4. For each combination of fuel type, payment method and month—
(a)the total annual cost of fuel for a discounted tariff customer (“D”), and
(b)the total annual cost of fuel for a customer paying a reference tariff (“R”),
on the assumptions that (in each case)—
(i)the customer’s rate of consumption of each fuel supplied to that customer is the mean rate of consumption of all the supplier’s discounted tariff customers;
(ii)the customer remains on that tariff for a year;
(iii)the price of the tariff on the last day of that month remains unchanged for that year; and
(iv)if the supplier charges different prices in different regions for the tariff, the price paid by the customer is the mean of the prices charged in each region in which the supplier has customers on that tariff.
5. The amount of each rebate provided by the supplier under Chapter 3 of Part 4, and the number of customers provided with a rebate of that amount.
PART 2Method to be used by the Authority to calculate the value of discounted tariffs provided by a relevant supplier
1. In relation to each month in a scheme year—
(a)for each combination of fuel type and payment method, (R – D) is to be multiplied by the relevant supplier’s number of discounted tariff customers on the last day of the month; and
(b)for each fuel type, the amounts calculated under sub-paragraph (a) for different payment methods are to be added together.
2. For each fuel type—
(a)in relation to each quarter, the mean of the amounts calculated under paragraph 1(b) for the months in that quarter is to be multiplied by the relevant weighting; and
(b)the amounts calculated under sub-paragraph (a) for each quarter in the scheme year are to be added together.
3. The amounts calculated under paragraph 2(b) for each fuel type are to be added together.
PART 3Supplementary
