Service interruptibility and instantaneous reduction of withdrawals

A significant earning opportunity for large companies with high energy consumption.

The operator of the national transmission grid, Terna, on a monthly basis, with validity for the month following the one in which the procedures are carried out, procures instantaneously interruptible and emergency resources based on the needs of the electricity system.

Which businesses can participate

The companies that own withdrawal points, also grouped in consortium form, that are in possession of the technical requirements for instantaneous and / or emergency interruptibility as defined in the dispatching rules provided for by the Code of transmission, development and safety of the network (Grid Code) and with a total available interruptible power of not less than 1 MW for each single site, can participate in the procedures for the procurement of the instantaneous and / or emergency interruptibility service.

How the interruptibility service takes place

The companies that are assignees of the instantaneous and / or emergency interruptibility service are required to stipulate the relative contract for the regulation of the service and the rights and obligations deriving from the assignment with Terna, which consists in the availability for some loads to suffer interruptions sudden in the face of the recognition of proportionate economic payments.

The holder of an interruptible load must be equipped with suitable devices that guarantee a real-time disconnection with an actuation time of less than 200 ms or in deferred time with an actuation time of 5 s.
