Block Exchange Notification

The Block Exchange Notification service - known by the French acronym NEB - involves market players notifying RTE, on either a day-ahead or intraday basis, of the sale (or purchase) of a block of electrical energy to (or from) another Balance Responsible Entity, or the delivery of a block of energy to a remotely metered site.

Block Exchange Notifications therefore allow:

  • two Balance Responsible Entities to exchange electricity blocks between them;
  • one Balance Responsible Entity to supply electricity to sites within the perimeter of another Balance Responsible Entity

RTE ensures that this notification is taken into account when calculating the Balance Responsible Entity's imbalance.


To use the Block Exchange Notification service,

  • you must be a Balance Responsible Entity
  • you must sign a contract with RTE based on the rules applicable to the Block Exchange service.

These can be found together in Section 3 of the Rules on Programming, the Balancing Mechanism and the Balance Responsible System.
