The shutdown of the bus system at the substation occurred today at 17:40 local time. This led to a partial restriction of the island's electricity supply. Some consumers received electricity again within ten minutes. However, work is still underway to restore the normal operation of the power system.
Note that there is no unified energy system on Sakhalin and the Kuriles. Each of the islands feeds on its own sources. There are four power plants operating in Sakhalin.
