​Outage tips

  • Call 911 for any emergency or life threatening situations.
  • Turn off or disconnect any appliances (stove or oven etc) or electronic equipment.
  • Keep one light on so you know when the power comes back on.
  • Don't bring gas or charcoal BBQs indoors. Be careful with candles.

  • Listen to a battery-powered or wind-up radio for information.
  • Limit how often you open and close your refrigerator and freezer doors to help food stay cool.
