Baltics Boost Grid Stability with Nine New Synchronous Condensers

Nine new synchronous condensers bolster Baltic grid stability. The EUR 114 million project, co-funded by the Connecting Europe Facility, ensures reliable operation post-synchronisation with continental Europe.

Baltics Boost Grid Stability with Nine New Synchronous Condensers

Latvia, Lithuania, and Estonia have bolstered their power grids with nine new synchronous condensers. This EUR 114 million project, co-funded by the Connecting Europe Facility, ensures stable frequency and reliable operation of the transmission system. The Līksna synchronous condenser station marks the completion of this power project across the Baltics.

AS 'Augstsprieguma tīkls' (AST), Latvia's power transmission system operator, led the project in cooperation with Siemens Energy and Enersense Latvija. The Līksna station, the third and final one in Latvia, was commissioned earlier than planned and provides 100 MVAr of reactive power. Together with the other eight stations, they contribute a total of 2,090 MVA·s of inertia to the Baltic power grid.

The project's completion coincides with the Baltic states' synchronisation with continental Europe on 8 February 2025. This synchronisation enables joint operation of power systems, enhances energy security, and facilitates renewable energy integration. AST, which owns 68.46% of shares in AS Conexus Baltic Grid, plays a crucial role in ensuring continuous, secure, and sustainable power transmission throughout Latvia.

The completion of the synchronous condenser project, with the Līksna station as its capstone, strengthens the Baltic power grid's resilience and reliability. This achievement, coupled with the successful synchronisation with continental Europe, paves the way for a more stable and secure power future in the region.
