Planning for the inevitable power outage can be thought of as a continuum from no backup power to complete coverage of all circuits in all locations. There is no single point on that continuum that is right for every business. For some businesses, locking the doors and waiting for power to return might be a viable alternative. For others, full operation for the duration of the outage is the only option. For most companies with branch operations, the best solution is often a strategic mixture of coverage based on the critical nature of products or services, location, population density or any number of other factors.
