The new Delegated Regulation 1227/2011 aims to establish detailed rules for the authorisation and supervision of Inside Information Platforms and Registered Reporting Mechanisms

April 9th, 2026 – The new Delegated Regulation first adopted on 30th January 2026, supplements Regulation 1227/2011 on wholesale energy market integrity and transparency (also known as REMIT), establishing the requirements and supervision of Inside Information Platforms (IIPs) and Registering Reporting Mechanisms (RRMs). IIPs are platforms through which energy market participants publish inside information with the potential to significantly affect wholesale energy prices, while RRMs are entities through which markets participants can report transaction data to the Agency for the Cooperation of Energy Regulators (ACER). Both categories, which were previously subject to a registration regime operated by ACER, will from now one have to follow the Regulation instead, which introduces several requirements that operators should meet and maintain.

The Regulation establishes new rules across four areas:

  • It defines the content of authorization applications, including identity documentation, organisational structure, data validation systems, security protocols, and a mandatory testing phase in which applicants must demonstrate ther technical capacity to submit data to ACER.
  • It sets out organisational requirements that authorised IIPs and RRMs must maintain, including data timeliness, validation systems, cybersecurity with explicit reference to the NIS2 Directive framework, conflict of interest management, business continuity, and backup arrangements.
  • It establishes a supervisory framework under which ACER may request information from authorised entities and respond to detected non-compliance.
  • It sets out procedures for authorization withdrawal, whether initiated by ACER or voluntarily by the operator, including a handover period of at least six months to protect client data.

The new changes will have a direct effect on entities currently registered or seeking authorisation as IIPs or RRMs under REMIT. This includes energy exchanges, data vendors, and reporting service providers operating in EU wholesale energy markets. It will also have substantial effects for energy market participants, including generators, traders, transmission system operators, and large industrial consumers, whom are indirectly affected insofar as they depend on IIPs and RRMs to fulfil their own REMIT disclosure and reporting obligations. ACER continues to hold supervisory authority, with national regulatory authorities being notified of authorisation decisions and certain compliance issues.
