Transparency has improved markedly over the past few years, with new rules under EU Regulation 543/2013 on submission and publication of data in electricity markets making European electricity market information more precise and comparable. It is now mandatory for EU Members States to submit fundamental information related to electricity generation, load, transmission and electricity balancing, which ENTSO-E now publishes on the ENTSO-E Transparency Platform as of 5 January 2015.
In 2016 a new data portal was launched called Power Statistics. This contains all data from Janurary 2016 onwards.
For historic data, up to December 2015 you may use the original data portal service. This statistical database encompasses a range of historical data sets regarding power systems of ENTSO-E member TSOs. ENTSO-E is the single data competence centre for European electricity transmission systems.
Within ENTSO-E’s Working Group Electronic Data Interchange, a coding scheme has been developed, managed and maintained to facilitate cross-border exchanges and to efficiently and reliably identify different objects and parties relating to the IEM and its operations. This is known as the Energy Identification Coding (EIC) scheme, approved by ENTSO-E for the harmonisation and implementation of standardised electronic data interchanges.
