'Synchronous area' means an area covered by synchronously interconnected TSOs, such as the synchronous areas of Continental Europe ('CE'), Great Britain ('GB'), Ireland-Northern Ireland ('IRE') and Northern Europe ('NE') and the power systems of Lithuania, Latvia and Estonia, together referred to as 'Baltic' which are part of a wider synchronous area.
Article 2(1) of the Network Code on requirements for grid connection of generators (NC RfG)
Synchronous area in the European Union Internal Electricity Market is an area covered by interconnected Transmission System Operators (TSOs) with a common system frequency in a steady state, such as the synchronous areas Continental Europe (CE), Cyprus (CY), Great Britain (GB), Ireland (IRE), Northern Europe (NE) and the power systems of Lithuania, Latvia and Estonia (Baltic) as a part of a synchronous area.
Synchronous areas do not stop at the European Union's borders and can include the territory of third countries - Recital 15 of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (System Operation Guideline - SOGL).
The Frequency Containment Reserves (FCRs) are dimensioned at the level of synchronous area (see Article 153 of the SOGL).
