Power supply in Spain has been approximately half-restored after the blackout on Monday, April 28. This was reported by Prime Minister Pedro Sanchez during a televised address: "According to data from the power grid, almost 50 percent of the power supply is already restored. The task now is to continue restoring the supply over the next few hours." Electricity is being supplied to Spain from France and Morocco. Disruptions in the power network were caused by sudden fluctuations in high-voltage lines according to a statement by Spain's grid operator Red Eléctrica. On the evening of April 28, Spain's Ministry of Interior declared a state of emergency nationwide.
