Public Consultation on the Imbalance Settlement Harmonisation Methodology (ISHM) Assessment

Public Consultation on ISHM Assessment

All TSOs have launched a public consultation on the assessment of the need for further harmonisation of imbalance settlement, in accordance with Article 52(2) of Commission Regulation (EU) 2017/2195 establishing a guideline on electricity balancing (EB Regulation) and Article 12(3) of the Imbalance Settlement Harmonisation Methodology (ISHM).

The Imbalance Settlement Harmonisation Methodology aims to further specify and harmonise the rules for imbalance settlement. Pursuant to the EB Regulation, all TSOs were required to implement this Methodology by January 2022.

Through this consultation, all TSOs seek input from stakeholders on the assessment of the need for further harmonisation of imbalance settlement. The assessment is based on the evaluation of the consequences and possible distortions resulting from non-harmonisation, pursuant to Article 59(3)(i) of the EB Regulation.

The public consultation:

  • Opened: 26 June 2026
  • Closes: 7 September 2026
