Electricity Market Transparency

​Transparency has improved markedly in Europe over the past few years, culminating in Regulation (EU) No 5 43/2013 of 14 June 2013 on submission and publication of data in electricity markets. Through this Regulation, it has now become mandatory for European Member State data providers and owners to submit fundamental information related to electricity generation, load, transmission and balancing for publication through the ENTSO-E Transparency Platform.

Transparency is essential for the implementation of the Internal Electricity Market (IEM) and for the creation of efficient, liquid and competitive wholesale markets. It is also critical for creating a level playing field between market participants and avoiding the scope for market power (if it exists) to be abused.This platform enables the provision of the required electricity market information for the future and further facilitates the development of efficient and competitive energy markets across Europe. Such developments support the steady evolution of electricity markets across Europe in terms of integration, competition

The ENTSO-E Transparency Platform

In accordance with Regulation 543/2013, the ENTSO-E Transparency Platform was launched on 5 January 2015.

  • ENTSO-E also published the Manual of Procedures, which provides information necessary to submit or extract data to or from the Platform. For more information, visit the dedicated page.

  • Following the launch of the new platform, the https://transparency.entsoe.eu/ website, on which TSOs had voluntarily published some market data since 2011, was de-commissioned in March 2015. The historical data from 2011-2014, which was previously published on entsoe.net, is available to download from the Transparency Platform: the Data Pre-5.1.15 section

  • In March 2015, the ENTSO-E Transparency User Group was formed to analyse user feedback and requirements and formulate recommendations as input to further improvements to the ENTSO-E Transparency Platform’s user interface and to its future development.
