PARAMETERS USED TO CALCULATE THE EX-POST DISCOUNT FOR A DAILY INTERRUPTION
Multiplier for daily standard capacity product
M = 2
Reference price
T = 1€/(kWh/d)/year
Number of Days on which an interruption occurred
D = 5d
Interrupted capacity
I = 1,000 kWh/d
Table 68:
Parameters used to calculate the ex-post discount for a daily interruption
The formula below is not set out in the TAR NC and is constructed per ENTSOG’s
assumption that it could take account of the amount of interrupted capacity. This
formula can be used for ex-post compensation for interruptions on within day
products.
Example for a within day interruption
Ex-post compensation = 3 × (M × S × T/365) × (I × D/24)
Where:
M
is the level of the multiplier corresponding to the daily standard firm capacity
product;
S
is the level of seasonal factor corresponding to the daily standard firm capacity
product, if any;
T
is the reserve price for yearly firm capacity product;
D
is the number of interrupted hours;
D/24
represents the proportion of the gas day for which the capacity was interrupted
;
For leap years, the formula shall be adjusted so that the figure 365 is substituted with the
figure 366;
I
is the amount of interrupted capacity.
PARAMETERS USED TO CALCULATE THE EX-POST DISCOUNT FOR A WITHIN-DAY INTERRUPTION
Multiplier for daily standard capacity product
M = 2
Reference price
T = 1€/(kWh/h)/year
Number of hours on which an interruption occurred
D = 5h
Interrupted capacity
I = 1,000 kWh/h
