Non-binding market demand survey on incremental capacity for interconnection points

We inform you that as of today, 7th July 2025, the Transmission System Operator has launched a non-binding market demand assessment on incremental capacity for interconnection points. Transmission System Operator, in accordance with the Articles 26 to 29 of the Commission Regulation (EU) 2017/459, invites all Network Users to fill in the non-binding incremental capacity survey which will be available for eight weeks, until 1st September 2025. 

Please note that the non-binding incremental capacity survey can be completed separately for demand indications referred to natural gas transmission on this link or hydrogen transmission on this link.

Participants are reminded that a non-binding request for firm capacity on an interconnection has to be submitted to both neighbouring transmission system operators. If two entities plan to submit a request jointly, one on the one side and the other one on the other side of the interconnection point, then the interest should be expressed in a joint request with both neighbouring operators at the interconnection point.

Please send duly completed survey to e-mail: SKR@plinovodi.si

In addition, stakeholders interested in hydrogen transmission capacity should be aware of ongoing significant regional projects and related market demand survey’s for IP's with neighboring transmission system operators.
