Electrical Interruptibility is included in the “Defence systems for the national electricity service” and the mechanism was launched by Terna in 2001. It aims to involve demand units connected at medium and high voltage for correct balancing of the national electricity grid. This service involves reduction in a customer’s withdrawal within 200 ms following a disconnection request from Terna, operator of the Italian national electricity grid.
How does Electrical Interruptibility work?
The service involves a company being prepared to interrupt their withdrawal of power from the grid within 200 ms. To enable Terna to perform this activity for correct balancing of the national electricity grid, users must equip themselves with an advanced system for real-time monitoring of consumption and to trigger disconnections.
This system is referred to as a UPDC (peripheral load-disconnection unit).
Technical requirements for parties that want to participate in the Electrical Interruptibility mechanism:
[
Minimum power 1 MW per site (HV/MV) – (annual demand of at least 7,000 MWh).
[
Installation of a UPDC system and participation in Terna auctions.
[
Readiness for instant disconnection.
Why participate in the Electrical Interruptibility service?
Companies willing to sign up to this mechanism supporting the electricity grid can earn in the form of a fixed annual fee and a variable fee for each request of € 3,000 per MW.

On Energy Team’s software platform, CloE an app is available specifically for interruptible users that tracks, analyses and stores communications between the UPDC and Terna, publishing information on a server for customers to consult historical data and calculate the remuneration due.
Discover the monthly reduction service for interruptible customers
Interruptible companies have the opportunity to participate in Terna’s new consumption reduction service, making themselves available to reduce the withdrawal of electricity from the grid. The call for the reduction can take place with two days notice for the period 10 February – 31 December 2023. For this availability, the companies will obtain a fee of up to €59,200/MW (pay as bid).
Energy Team participated in the service involving its customers for a quantity equal to 75 MW out of a total of 258 MW awarded in the auction held on February 7, 2023.
