EXAMPLE 2 FOR CLASSIFICATION OF INTERRUPTIBLE CAPACITY PRODUCTS
October 2017 – September 2018 – IP 2
IP 2 – entry
IP 2 – exit
Explanation of the probability of interruption
Interruption if counter-flow is too
high
Interruption due to the utilisation of the
neighbouring infrastructure operator
Explanation of the historical and/or forecasted
data used to estimate the probability of
interruption
Forecasted probability based on
trend in probability since 2015
n/a
Probability of interruption (‘Pro’)
0.1
n/a
Data used for the estimation of the risk of
interruption
Data sheet to be included
n/a
Value of the adjustment factor ‘A’
1
n/a
Ex-ante Discount (Di_(
ex-ante
))
10%
n/a
Ex-post Discount (‘Yes’ or ‘n/a’; if ‘Yes’ then explain
how the conditions were met)
n/a
Yes; the conditions are met as
there was no interruption due to
physical congestion in the year

Table 75:
Example 2 for classification of interruptible capacity products
The details provided in tables 69 and 70 are only indicative. Further to stakeholder
feedback, ENTSOG notes that a more detailed level of information will have to be
provided by the TSO or NRA when actually filling out these tables. This information
should include product type, average duration of potential interruptions, average
interrupted capacity, likelihood of interruption based on historical data, the relevant
points, nominations, flow levels, etc. Also, events and flow patterns on the network
which may trigger an interruption, for example falling pressure at an IP, and why.
