“ASSPDsr” means—
(a) subject to paragraph (b), the actual net demand of S is responsible during periods of high demand (“AD”) in the relevant months; or
(b) if, at the date on which the calculation in sub-paragraph (2) is to be made, the Settlement Body does not have the data necessary to calculate AD for all electricity suppliers for one or more of the relevant months, AD in the relevant months for which the Settlement Body has that data;
