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.
