FAQs

  • Q: How do you decide which customers should have their electricity cut?

    Groups of circuits in each utility's service area are picked so a certain amount of demand can be eliminated and the electric system can be balanced. The circuits are from a wide area, so small numbers of customers in varied parts of the state would be affected. Utilities attempt to ensure that facilities such as hospitals, airports, sewage treatment plants and specific sections of large cities served by networked circuits are exempt from these blackouts.
