Does that mean they have cables physically connecting their AC grids to the European AC grid? How many megawatts can those cables transfer? Which direction is the transfer going to be? Will they be buying electricity from Europe or selling electricity to Europe? > All electricity interconnections with Russia and Belarus have been permanently disconnected. How many megawatts were those connections?

> Does that mean they have cables physically connecting their AC grids to the European AC grid? Yes, in the Suwalki Gap (border between Poland and Lithuania). Until this point, the connections were HVDC including to Sweden and Finland (across the Baltic Sea). > Will they be buying electricity from Europe or selling electricity to Europe? They already participate in the EU electricity market (through the HVDC lines), some hours buying cheap power from clean sources, sometimes selling expensive non-renewable power.

  Note that Finland and Sweden aren't on the European Continental grid, but the Scandinavian grid, which has its border within Denmark. Thiis means there's now an additional route for Finland to sell power even further south.

    Do you happen to have a link to a news item saying something changes for Finland? You are the first one I see mentioning this - I suppose because the HVDC lines were already there.

      I'm mistaken, the existing link between Lithuania and Poland was already in use, and the new one isn't built yet: https://en.m.wikipedia.org/wiki/Harmony_Link https://en.m.wikipedia.org/wiki/Harmony_Link

        Looking at the orange lines on the map here, the connections between Estonia and Latvia may have been missing before this project: https://www.entsoe.eu/news/2025/02/09/entso-e-confirms-successful-synchronization-of-the-continental-european-electricity-system-with-the-systems-of-the-baltic-countries/ https://www.entsoe.eu/news/2025/02/09/entso-e-confirms-succe...
