Regulation 3 Calculation of thermal energy

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

(1)

The number of therms or kilowatt hours conveyed by a public gas transporter to any take off point during any gas period shall be calculated in accordance with the following formulae—

number of therms so conveyed=A×B105.5number of kilowatt hours so conveyed=A×B3.6

where

  • A is the number of cubic metres in the converted volume of gas conveyed to the take off point during the gas period and B is the average calorific value of gas calculated in accordance with paragraph (2) below.

(2)

The average calorific value of gas so conveyed during any such gas period shall be calculated by adding the daily calorific values calculated in accordance with regulation 4 below for each gas day in that gas period and dividing the sum by the number of those gas days but so that any amount of less than 0.1 megajoules per cubic metre shall be ignored.
