Creating a new transmission code for the power grid


Following preparations to connect Turkey’s power network with the continental European power grid under a previous project, Turkey’s electricity transmission regulations needed to be harmonised with European Network of Transmission System Operators for Electricity (ENTSO-E) requirements. The new transmission code defined the technical principles and requirements governing the operation and use of the Turkish power system and the roles in this regard of the players involved in it. It also set out the rules to integrate wind power into the grid.

The project’s aims and core activities

The project’s purpose is to harmonise the Turkish power transmission code with that of the ENTSO-E for continental Europe. The Turkish Electricity Transmission Corporation (TEİAŞ) is playing a central role in implementing the project.

The draft code will be compiled after an examination of the relevant ENTSO-E handbook and its market and technical regulations. Upon completion, the draft code will be submitted to the Energy Market Regulatory Authority for approval.

Training for TEİAŞ staff is also being organised, which will involve technical study visits for senior staff to a transmission company in an EU country. Subsequently, engineers from specific departments will be given training in ENTSO-E system requirements.

The new code will enhance the parallel synchronisation of the Turkish power system with the central European grid, leading to a better functioning system in the cross-border electricity trade between Turkey and its European neighbours. Improving the overall interconnected power system, operational security, and quality of supply for the end users will enhance the electricity transmission system performance in Turkey and in the ENTSO-E system. This will ensure better functionality in the operation of the general power system.
