Terna and Swissgrid Launch Public Consultation on Intraday Continuous Capacity Allocation Rules for IT-CH Border

Terna and Swissgrid have opened a one-month public consultation (7 September 2026 to 7 October 2026) on a proposed mechanism for Intraday Continuous Capacity Allocation (IDCC) intended to enable efficient cross-border intraday trading on the IT-CH border.

The introduction of an intraday continuous capacity allocation mechanism on the IT-CH interconnector would give market participants a formal process to access cross-border intraday capacity in real time, potentially improving intraday liquidity and price convergence between the Italian and Swiss markets ahead of delivery.

This consultation targets a specific and previously uncaptured design gap: continuous intraday capacity allocation rules for a border (IT-CH) that sits outside the core XBID/SDAC intraday coupling arrangements applicable to many other EU borders, given Switzerland's non-EU status. The joint TSO-led initiative (rather than a NEMO or ACER-driven process) suggests this is being handled as a bilateral technical arrangement, similar to other Swiss-border capacity mechanisms. Key open questions for the consultation period include how allocated capacity will interact with existing day-ahead IT-CH allocation, whether allocation will use explicit or implicit methods, and how the rules will align with broader Market Network Code principles referenced in the ENTSO-E consultation framing. Given the one-month consultation window with no stated decision or implementation date, this event remains at an early design stage; the next material development will be publication of consultation feedback and a revised or finalized rules document from Terna and Swissgrid.
