Build a backup plan around time and priorities.
A useful outage plan starts with the loads you need to keep running, how long the outage may last, and which loads can wait.
Start with the outage window
Short interruptions and multi-day outages create very different energy requirements. Zaron Energy organizes planning around realistic time windows so you can see how quickly essential loads consume stored energy.
