Founded in 2008, Coreso encompasses nine European operators, which are also its shareholders (Elia in Belgium, Eirgrid in Ireland, 50hertz in Germany, National Grid in the UK, REE in Spain, REN in Portugal, RTE in France, SONI in Northern Ireland, Terna in Italy).

Coreso provides services to secure energy transmission for over 55% of the population of the European Union. Located in Brussels, about fifty engineers, seconded from their companies, combine their expertise 24 hours a day, 7 days a week to anticipate the operation both in the short term and the long term.

The mission of CORESO is to proactively support TSOs to ensure security of supply on a European regional basis. Coreso focuses its coordination activities and thus provides the highest added value from a year ahead until Intraday (few hours before real time). Coreso, as the other RSCs, is a service provider of nationally regulated TSOs.

ENTSO-E, the European Network of Transmission System Operators, represents 43 electricity transmission system operators (TSOs) from 36 countries across Europe. ENTSO-E was established and given legal mandates by the EU’s Third Legislative Package for the Internal Energy Market in 2009, which aims to further liberalise the gas and electricity markets in the EU.
