On 9 February 2025, at 14:05 EET, Estonia, Latvia and Lithuania successfully synchronised their electricity grids with the Continental Europe Synchronous Area (CESA), marking a historic milestone in their journey towards strengthened energy system resilience and integration with the Continental Europe electricity grid. At the same exact moment, they disconnected their grids from the IPS/UPS system previously governed by the BRELL agreement with Russia and Belarus.
This extraordinary feature marks the completion of a project that started in 2014 with the realisation of two studies helping to identify the technical and financial requirements for a successful Baltic synchronisation with the Continental Europe Network (CEN). The project has received more than 1,2 billion EUR in funding from the Connecting Europe Facility (CEF) Energy programme. The CEF Energy funding facilitated the implementation of studies, the development of infrastructure and the purchase and installation of the required IT equipment.
The successful completion of the Baltic Synchronisation project constitutes a prime example of successful cross-border cooperation and commitment. Multiple stakeholders from the involved countries, such as transmission system operators, contractors, CINEA, and the governments of the Baltic States and Poland have exerted a collective effort that resulted in their energy independence from the previous system and in strengthening the reliability and security of the entire CESA system. Cross-border infrastructures, such as interconnections between Latvia-Estonia, and Lithuania-Poland, that allow grid stabilisation and decrease risks from the synchronisation process, are the result of this multiannual, multi-stakeholder cooperation across borders.
