This is the best summary I could come up with:

Estonia, Latvia and Lithuania have agreed to speed up their integration into the European Union's electricity system in order to desynchronize from the Russian power grid.

The three Baltic countries, which are EU and NATO members, still remain a part of the Soviet-era BRELL power system that also includes Belarus and whose frequencies are controlled by Moscow, leaving them vulnerable to possible energy weaponisation by the Kremlin.

The countries' leaders signed the deal on Thursday and said in a statement that their synchronisation with the Continental Europe Network "holds strategic importance not only for us but for the entire European Union" and that the continued reliance on the BRELL system "is a threat to the Baltic States' energy security".

European Commission chief Ursula von der Leyen welcomed the announcement, writing on X, also known as Twitter, that "this will further reinforce the strength and resilience of the EU's electricity grid, and our energy independence overall."

Energy Commissioner Kadri Simson said "this historical agreement" will see the three Baltic countries join the EU electricity grid "almost one year earlier than previously intended."

I'm a bot and I'm open source!

Great news for sustainability, too
