The blackouts are intended to manage a dramatic fall in power generation capacity caused by a massive earthquake and tsunami that hit the country on Friday. Tokyo Electric Power Co. has lost about 27 percent of its electricity generation capacity and will be short of demand by about 10 million kilowatts. The number of dead and missing stands at around 3,000, but that figure is growing by the hours. Several electronics companies have plants in the region and they’ve been offline since Friday. Several companies have announced plans to temporarily suspend production at some domestic factories.”]
