In addition to the new infrastructures, operation of the TRF is based principally on a short-term market mechanism: locational spread.
This mechanism uses the most flexible sources, i.e. the underground storage facilities: it is essential that these sources be available over the entire winter.
Monitoring of the stocks then seems necessary in order to:
- Ensure that, over the entire winter, the Shippers will have highly localised flexibility resources in order to meet the localised spread calls
- Activate a preventive mechanism in the event of a recognised risk relating to the availability of this short-term flexibility.
- Weekly publication between 1 November and 1 April
- Requirement which must be determined over 7 days or 15 days
