HUDEX Hungarian Derivative Energy Exchange



HUPX and CEEGEX are Registered Reporting Mechanisms (RRMs) for the automated reporting of HUDEX trading data in compliance with REMIT Art.8. HUPX and CEEGEX are continuously enhancing its reporting service in accordance with new specifications and requirements communicated by ACER.

By using the reporting service, market participants will:

  • have access to a standardised user interface,
  • reduce their reporting efforts of REMIT transaction data significantly,
  • be able to download REMIT data files individually and
  • monitor reported data and reporting status via an easily accessible web interface.

“REMIT affects everyone who participates in, or whose conduct affects, wholesale energy markets within the Union. It makes no difference whether or not the person resides within the EU or whether or not they are professional investors. Moreover, non-EU and non-EEA market participants are covered by REMIT when entering into transactions, including the placing of orders to trade, in one or more wholesale energy markets in the Union.

Accordingly, the obligations to register under REMIT with the competent NRA and to report data to the Agency according to Article 8(1) and (5) of REMIT also applies to such non-EU and non-EEA market participants. The same holds for the prohibitions of market abuse pursuant to Articles 3 and 5 of REMIT.”
