Israel Electric Corporation (IEC) has installed a warning system to inform citizens regarding the level of reserves available. The system is based on four colors: condition green (regular electricity supply); condition yellow (consumption demand is close to available supply capacity and IEC is acting to balance the system); condition orange (consumption demand is close to the generation capacity limit and electricity blackouts are possible. IEC will update consumers so that they may act in a timely manner); condition red (consumption is higher than generation capacity and there are blackouts in certain areas. IEC is asking the cooperation of the public to re-balance the system)
