Trail synchronization of European, Ukrainian and Moldovan Power grid running
The European Transmission System Operators started a trial synchronization of the continental European power system with the power systems of Ukraine and Moldova on 16 March 2022.
The Continental Europe Synchronous Area (CESA) is the world's largest synchronous electricity network (by connected power). The synchronous frequency is 50 Hz, and the area serves over 400 million customers in 24 countries, including most of the European Union. The transmission system operators in CESA are responsible for maintaining the frequency of 50 Hz to ensure the system's stability. This means that energy resources and consumption must always be balanced throughout the synchronous area.
The European Network of Transmission System Operators for Electricity, is the association for European transmission system operators. Its 39 members, representing 35 countries, are responsible for the secure and coordinated operation of the European electricity grid, the largest interconnected electricity network in the world.
The acceleration of the synchronization project, which has been ongoing since 2017, was possible thanks to previous studies and the adoption of risk mitigation measures. A positive analysis confirmed that emergency synchronization is technically feasible and that measures can be taken to ensure secure power systems. It is an important milestone for the continental European TSOs working with Ukrenergo and Moldelectrica, which operate their respective power systems under challenging conditions.
The synchronization process involves the cooperation of ENTSO-E, the European Commission, all TSOs involved, and their national authorities for their support and assistance in the synchronization process.
