# The Electricity Capacity (Supplier Payment etc.) Regulations 2014, Paragraph 3: Capacity market supplier charge: revised annual calculations

Extent: E+W+S

(1) The Settlement Body must, as soon as reasonably practicable after relevant demand and CM EII excluded electricity data for all periods of high demand in year X is available, calculate for each electricity supplier (“S”)—
(a) S’s revised share of capacity market supplier charges in respect of year X (“RSCsx”);
(b) S’s revised capacity market supplier charge in respect of year X (“RACMSCsx”);
(c) S’s revised monthly capacity market supplier charge in respect of each month of year X (“RMCMSCsm”).
(2) RSCsx must be calculated in accordance with the formula—
RSCsx=ASSPDsx∑sASSPDsx.
(3) RACMSCsx must be calculated in accordance with the formula—
RACMSCsx=∑iAACPix×RSCsx.
(4) RMCMSCsm must be calculated in accordance with the formula—
RMCMSCsm=RACMSCsx×WFmx.
(5) In this paragraph—
“∑iAACPix” means ∑iACPix, within the meaning given in paragraph 2(5), minus any reductions in the total amount of capacity payments payable to capacity providers in respect of year X as a result of—
(a)a capacity agreement being terminated; or
(b)a capacity payment being reduced or forfeited under the Principal Regulations;
“” means the actual relevant demand of S during periods of high demand in year X less the actual CM EII excluded electricity supplied by S during periods of high demand in year X.
