Baltics Complete Power Grid Synchronisation with Europe

The Baltic countries have completed a significant project, marking their successful synchronisation with continental Europe's power grid. This synchronisation, achieved on 8 February 2025, ensures stable frequency control and reinforces energy security in the region.

The project involved the installation of nine synchronous condensers across Latvia, Lithuania, and Estonia. These devices, installed by AS 'Augstsprieguma tīkls' (AST) in collaboration with Siemens Energy and Enersense Latvija, provide a total of 100 MVAr of reactive power and 2,090 MVA·s of inertia for the Baltic grid.

The Līksna synchronous condenser station in Latvia, commissioned earlier than planned, is one of these installations. It contributes significantly to the stability and reliability of the transmission system. The total investment for this project amounted to EUR 114 million, with 75% co-funded by the Connecting Europe Facility (CEF).

The completion of the synchronous condenser project in Latvia and across the Baltics, marked by the Līksna station, paves the way for enhanced integration of renewable energy and improved energy security in the region. AST, as the power transmission system operator in Latvia, played a crucial role in this achievement.
