Algorithmic Trading In Energy Markets Features Again In ACER's Latest REMIT Quarterly

REMIT is the EU-wide framework that detects and deters market manipulation and abuse in wholesale energy markets. It enhances transparency and trust in the integrity of Europe’s energy markets.

ACER’s REMIT Quarterlies provide updates on REMIT-related activities, helping stakeholders stay informed. Due to strong interest from readers, the latest issue continues the series on algorithmic trading in energy markets.

What’s new?

Following the overview of algorithmic trading and its implications under REMIT in the 44^th edition, the 45th REMIT Quarterly explains how ACER is adapting its market surveillance to the growing use of this practice in wholesale energy markets.

Algorithmic trading uses computer programs to automatically execute trades based on pre-defined instructions (such as when to buy or sell), often at speeds and volumes beyond human capacity. As energy markets become increasingly automated, REMIT continues to evolve to ensure that potential market abuse can be effectively detected and addressed, regardless of whether trading is manual or automated. 

Also in this Quarterly:

• Takeaways from two joint ACER-European Commission events: the annual REMIT workshop (11 June 2026) and the webinar on new REMIT implementing rules (23 April 2026). 

• A case report on the Hungarian energy regulator’s decision to fine Hungaro Energy for manipulating the gas market.

• Updates on market surveillance, including statistics on the 453 REMIT breach cases under review at the end of Q2 2026.

• Changes to the geographical scope of inside information platforms (IIPs) and how market participants are using them.

• Recent energy market trends, showing a continued increase in trading on organised market places (OMPs), driven by growth in natural gas forward markets.
