EU interconnection points - system development projects

Our Company regularly monitors the demand both via binding and non-binding market demand assessments relevant to interconnection points. Further to the Commission Regulation (EU) 2017/459 at least in each odd-numbered year our Company cooperates with the adjacent transmission system operators in the processes of assessing market demand for incremental capacity and of conducting technical studies for incremental capacity projects for the joint interconnection points.


Our Company launches a non-binding market survey for incremental capacity for interconnection points according to Article 26 of Commission Regulation (EU) 2017/459 (CAM NC) between 5 July and 30 August 2021.

The non-binding demand indications can be submitted by filling out the incremental capacity survey sheet available at this link and sent to our Company by 30 August 2021, under the conditions detailed in the respective newsletter.

The corresponding Resolution No. H1617/2021 of the Hungarian Energy and Public Utility Regulatory Authority regulating the application rules and payment terms of the registration fee is accessible here in Hungarian. The English translation of the Attachment No. 1. thereto - detailing the specific application rules and payment terms - is accessible here for informative purposes exclusively.

The respective market demand assessment reports are published at the given interconnection point below.
