Sergey Boyarkin has said that the shutdown of Ignalina Nuclear Power Plant combined with Polish plans to scrap coal-fired generation in compliance with environmental regulation means that the Baltic region faces an energy crisis by 2015.[9][13] He also has said that Kaliningrad Oblast will be isolated from electricity supplies from Russia if the Baltic states de-synchronize themselves from the Russian electricity grid and join the synchronous grid of Continental Europe (ENTSO-E grid).[13] He also mentioned technical complications and unreliability in electricity transfer from Smolensk Nuclear Power Plant, the main supplier of Kaliningrad Oblast, via Belarus and Lithuania.[3]
