Finland's grid operator, Fingrid, however, said it lacked the replacement parts Ukraine needs."The Ukrainians have asked European grid operators for spares, and we have also received a request.We naturally strive to help if we have the parts, but it's my understanding that Ukraine's system isn't an exact match with ours," Timo Kaukonen, who manages operational planning at Fingrid, told Finnish news agency STT.He noted that Ukraine had already started conserving electricity ahead of Saturday's drone attacks on power infrastructure.Ukraine maintains that Russia's strategy is to damage critical infrastructure as winter approaches, leaving people without heat or electricity and triggering a mass exodus of Ukrainian refugees into western states."
