IESOE Transparency Platform 

The Electricity Interconnection in South-Western Europe (IESOE) transparency platform (www.iesoe.eu) is a project which has been coordinated by REN, Réseau de Transport d'Électricité (RTE), Red Eléctrica de España (REE) and the Office National de l'Electricité et de l'Eau Potable (ONEE), the Transmission System Operators (TSO) of France, Spain, Portugal and Morocco. This project is a decisive step to greater transparency in electrical power markets.

The platform provides Market Agents and the general public with coordinated, coherent and free information on the interconnection capacities between the electrical systems of France, Spain, Portugal and Morocco and their respective utilization.

Real time information is also provided on the utilization of interconnection capacity as well as information on long-term congestion management mechanisms, prices of organized markets and economic information on interconnection management.
