Annex N
Article 16 – Example of Calculating
Discounts for Interruptible Capacity
Products
EX-ANTE DISCOUNT
Example:
Calculation of ex-ante discount for monthly standard capacity product for
interruptible capacity, based on the formula:
The Pro factor is calculated as set out in Article 16(3) according to the following
parameter.
PARAMETERS USED TO CALCULATE THE PRO FACTOR
Expectation of the number of interruptions over D
N = 5
Average duration of the expected interruptions expressed in hours
D
int
= 12 hours
Total duration of monthly standard capacity product for interruptible capacity in hours
D = 744 hours
Expected average amount of the interrupted capacity for each interruption related to
monthly standard capacity product for interruptible capacity
CAP
av.int
= 150,000 kWh/h
Total amount of interruptible capacity for the respective type of standard capacity product
for interruptible capacity
CAP = 10,000,000 kWh/h
‘A’ factor
A = 100
INTERRUPTIBLE RESERVE PRICE
Example:
Calculation of reserve price for monthly standard capacity product for
interruptible capacity in accordance with Article 16(1):
The discounted reserve price for a standard capacity product for interruptible
capacity is calculated by the actual reserve price as set out in Article 14 or 15
combined with the ex-ante discount as described in the previous section. Following
parameters are used in this example.
