How do we cooperate?


To further enhance interaction and exchange of ideas, ACER has been holding its annual Energy Market Integrity and Transparency (EMIT) Forum each September/October in Ljubljana since 2017. The event is attended by policy experts from the Member States, energy traders and consumers, transmission system organisations and NRAs.

ACER periodically meets with energy exchange surveillance technical experts and financial authorities via the Market Surveillance Forum (MSF) and the Energy Trading Enforcement Forum (ETEF).

ACER also regularly cooperates with the European​ Securities and Markets Authority (ESMA), the competent financial market authorities of the Member States and, where appropriate, national competition authorities. ACER also engages in international cooperation.

Memorandums of Understanding (MoUs)

The scope and practical terms of implementing the cooperation foreseen in REMIT is defined in a Memorandum of Understanding (MoU).

ACER has signed MoUs with NRAs, ESMA, organised market places (OMPs), and the US Federal Energy Regulatory Commission (FERC).

Whilst the MoU with the NRAs is a multilateral one, the MoUs with organised market places are bilateral. This allows organised market places to set out the content and procedures for the cooperation on more specific issues related to market monitoring under REMIT. ACER had signed MoUs with eight organised market places across the European Union.  ​
