Regulation 7 Calculation of thermal energy

(1)

Where a public gas transporter makes a declaration of calorific value or adopts a declaration of calorific value made by another public gas transporter in accordance with regulation 8(1) below in respect of any area within an authorised area of the transporter, the number of therms or kilowatt hours conveyed by the transporter to any take off point situated in the area to which the declaration relates during the relevant period shall be calculated in accordance with the following formulae—

number of therms so conveyed = \frac{A \times B}{105.5} number of kilowatt hours so conveyed = \frac{A \times B}{3.6}

where

A is the number of cubic metres in the converted volume of gas conveyed to the take off point during the period and B is the declared calorific value of the gas.

(2)

In paragraph (1) above “a relevant period” means any gas period during which a declared calorific value has effect.
