4 Transparency Regulation

ENTSO-E’s Transparency Platform (Art. 3, Regulation 543/2013) centralises data relating to the generation, transportation and consumption of electricity at the European level. The data are collected from data providers, including TSOs and other qualified third parties. Depending on the users’ needs, these data can serve various purposes, such as market analysis, research or trading. The TP is also instrumental for the monitoring and regulation of power markets. Start-ups and new players increasingly use the TP’s wealth of data for delivering more value to customers, for example through shedding light on life-CO2 emissions by country, wind generation and more.

ENTSO-E reviewed the Manual of Procedures (MoP) and the Memorandum of Understanding (MoU) data quality requirements and consulted stakeholders on the amendments to the MoP v3r3. The amendments were submitted to ACER in October 2021.

In 2021, the TP was also amended for further publications and data collections, some of which are used only with a limited number of parties:

  • Transparency requirements from Art. 12 EBGL and Title 11 SOGL
  • Transparency requirements by the implementation frameworks of the European balancing platforms
  • Information to be made available to ACER for monitoring activities according to the list of information of Art. 82 CACM and Art. 63 FCA.

Finally, ENTSO-E also developed the TP for FSkar purposes and is carrying out the TP architectural study to respond to the ever-growing publication requirements.
