State enterprise Ukrenergo plans to file a lawsuit to international court demanding requirement for losses caused by the illegal seizure of its assets as a result of the annexation of Crimea against the newly formed Krymenergo, company acting director Vsevolod Kovalchuk has said.

"We won't sue with Russia, we will sue with certain legal entities, which now use our property, i.e. with Krymenergo. They expropriated Krymenergo, which operates the distribution networks and the Crimean power system that operated our power grids. They united them into one company, adding partially expropriated private generation, and made a unified enterprise," he said in an interview with Interfax-Ukraine.

"The company is allegedly Crimean, but registered as a legal entity under Russian laws. All the registers of the State Property Fund say this is property of Ukraine, while the occupiers use it. We do not receive remuneration from this. Therefore, we have every right to claim compensation. The question is not what the legal status of Crimea is and what Russia thinks about this. A legal entity of the Russian Federation backed by the Russian Army seized our property and it is making money. The essence of the claim is this. It's not about politics," Kovalchuk said.
