Since February 21, Europe has made a significant step forward in energy diversification and getting rid of dependency on Russian oil and gas. Of course, diversification of the energy flow is important. Europe is increasing renewables shared with Ukraine. We also see its rebuilding and maintaining the mixture of energy sources and the development of clean energy.
I would also like to say that we are already building strong co-operation with Canada in the energy sector. Just this year, the Canadian company Cameco and the Ukrainian operator of all of our nuclear power stations signed a 10-year contract for the supply of uranium, and Canada is helping us. Before, pre-wartime—by which I mean before 2014—Ukraine was buying most of this nuclear power fuel from Russia. Now we are buying it from the Canadian-owned company Westinghouse, and Cameco will provide uranium as a source for production of this nuclear fuel, so we really appreciate the strategic partnership that has started. The contracts were signed this year.
We also signed an MOU with our hydro power operator and another Canadian infrastructure company to help us to build hydro power facilities in Ukraine, because, in the Ukrainian strategy for rebuilding, Ukraine sees itself as the energy hub for Europe, having one of the most developed energy infrastructures in electricity, oil and gas. We have the biggest gas storage capability on the European continent, which is, even during the war, widely used by all of the European gas traders, so Ukraine will, of course, put a lot of effort into rebuilding the energy sector and into building more capacity in gas production, renewable energy and nuclear, which, as of today, is 50% of Ukrainian electricity production. We see here big opportunities for co-operation with Canadian companies.
