Paragraph 3 Capacity market supplier charge: revised annual calculations

(1)

The Settlement Body must, as soon as reasonably practicable after net demand 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 (“RSC_sx”);

(b)

S’s revised capacity market supplier charge in respect of year X (“RACMSC_sx”);

(c)

S’s revised monthly capacity market supplier charge in respect of each month of year X (“RMCMSC_sm”).

(2)

RSC_sx must be calculated in accordance with the formula—

R S C_{s x} = \frac{A S S P D_{s x}}{\sum_{s} A S S P D_{s x}} .

(3)

RACMSC_sx must be calculated in accordance with the formula—

R A C M S C_{s x} = \sum_{i} A A C P_{i x} \times R S C_{s x} .

(4)

RMCMSC_sm must be calculated in accordance with the formula—

R M C M S C_{s m} = R A C M S C_{s x} \times W F_{m x} .

(5)

In this paragraph—

“∑_iAACP_ix” means ∑_iACP_ix, 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—
1. (a)
  
  a capacity agreement being terminated; or
2. (b)
  
  a capacity payment being reduced or forfeited under the Principal Regulations;
“ASSPD_sx”means the actual net demand of S during periods of high demand in year X.
