Overview

On 27 March 2025, ACER received the transmission system operators’ (TSOs’) proposal to amend the Harmonised Allocation Rules (HAR) for long-term electricity transmission rights.

The harmonised allocation rules apply to all long-term transmission rights allocations conducted within the European Union. They provide specifications for the auctioning of long-term transmission rights (including use and curtailment of long-term transmission rights, eligibility criteria, etc.) and go through a review process every two years. 

Why we are consulting

The TSOs’ proposal updates various elements of the HAR related to arrangements with market participants to consider upcoming market changes (e.g. introduction of 15 minutes market time unit in day-ahead) and recent incidents (e.g. single-day ahead market decoupling in June 2024).

To inform its decision-making process, ACER encourages stakeholders to submit their inputs until 22 May 2025.
