They do not define exactly who is in what block. That, of course, is for security purposes. What happens is now, when we go into a warning stage, the word is put out to the media and that's when radio and television stations start broadcasting that people should conserve because when we go into this stage 1 or stage 2, people and commercial businesses are required to cut back on their energy consumption in hopes of avoiding a stage 3 alert and what usually follows is rolling blackouts. It's been different each time, but sometimes we have seen where we have had adequate warning and people have been able to cut back on their use. Other times it's gone from stage 2 to stage 3 blackouts very quickly.
People have no idea that it's coming, unless they have their radio or television on.
Block 50 are areas exempt from outages. Up until April, oil refineries were exempt, but now the oil refineries have been told they are no longer exempt, but they have not been told which block they are in. California has rotated blackouts through the 14th block, as of today. If there are more blackouts on Tuesday, we will proceed through the rest of Block 14 and then go back to Block 1 and start all over again. But many of these refineries have no idea when to expect these blackouts.
