ENTSO-E (European Network of Transmission System Operators for Electricity)
ENTSO-E was established by European Union countries in 2009, in order to increase energy supply security by creating a common internal electricity market model with grid integration, to maximize electricity generation-transmission-distribution efficiency and to minimize environmental problems. 42 transmission system operators from 35 countries are members of ENTSO-E.
Trial synchronous parallel operation between Turkish Power System and ENTSO-E Continental Europe Synchronous Area (CESA) was initiated on 18 September 2010. With the completion of the trial synchronous parallel operation phase, permanent connection between our country and ENTSO-E CESA electrical systems has been provided with the "Long Term Agreement" signed on April 14, 2015.
In 2021, the existing Long Term Agreement was revised within the framework of the Synchronous Region Framework Agreement signed among the Transmission System Operators that are members of ENTSO-E and re-signed between TEİAŞ and ENTSO-E.
With permanent connections, Türkiye electricity market has entered into a legal way for integration with the European internal electricity market. On January 14, 2016, "Observer Membership Agreement" was signed and TEİAŞ became the first and only Observer member of ENTSO-E.
TEİAŞ representatives who were participating to the special working group studies for the connection of Türkiye to ENTSO-E before permanent connection, have also started to participate in the works carried out in a large number of different working groups and sub-committees of ENTSO-E after the Long Term Agreement and Observer Membership.

EURELECTRIC (The Union of the Electric Industry)
EURELCTRIC is the industry association representing the common interests of the electricity industry at European level. The goal of EURELECTRIC with members from 32 different countries; as a professional organization, to create a platform where problems encountered in the electricity sector can be discussed. It has an impact on the decisions taken in the EU Commission through the news, notifications and reports it publishes.
TESAB was established in 2005, and since this date, TESAB has been representing our country in EURELECTRIC. TESAB directs its experts, to EURELECTRIC Committees and Working Groups through its member companies, NGOs and individuals and contributes to EURELECTRIC reports.
TESAB established the EURELECTRIC Coordination Committee in 2020 in order to ensure these works are carried out in a coordinated manner. The staff of our Corporation are members of the working groups established under the EURELECTRIC Coordination Committee and closely follow EURELECTRIC activities.
