Power Outage Prep

Planning for a pPower Outageower outage will also help prepare you for other types of emergencies. 

Read the guide, keep it in a handy spot, such as in your emergency kit and be ready when a power outage happens.

  1. Step 1: Prepare Your Home
  2. Step 2: Make an Emergency Plan
  3. Step 3: Get an Emergency Kit
  • You can install a non-electric standby stove or heater. Choose heating units that are not dependent on an electric motor, electric fan, or some other electric device to function. It is important to adequately vent the stove or heater with the type of chimney flue specified for it. Never connect two heating units to the same chimney flue at the same time.
  • If you have a wood-burning fireplace, have the chimney cleaned every fall in preparation for use and to eliminate creosote build-up which could ignite and cause a chimney fire.
  • If the standby heating unit will use the normal house oil or gas supply, have it connected with shut-off valves by a certified tradesperson.
  • Before considering the use of an emergency generator during a power outage, check with the furnace, appliance, and lighting fixture dealers or manufacturers regarding power requirements and proper operating procedures.

People with Disabilities or Others Requiring Assistance

Consider how you may be affected in a power outage, including:

  • Your evacuation route - without elevator service (if applicable)
  • Planning for a backup power supply for essential medical equipment
  • Keeping a flashlight and a cell phone handy to signal for help
  • Establishing a self-help network to assist and check on you during an emergency
  • Enrolling in a medical alert program that will signal for help if you are immobilized
  • Keeping a list of facilities that provide life-sustaining equipment or treatment
  • Keeping a list of medical conditions and treatment
  • If you live in an apartment, advise the property management that you may need assistance staying in your apartment or that you must be evacuated if there is a power outage. This will allow the property manager to plan and make the necessary arrangements on your behalf.

During A Power OutageOncor

  • First, check whether the power outage is limited to your home. If your neighbors' power is still on, check your own circuit breaker panel or fuse box. If the problem is not a breaker or a fuse, check the service wires leading to the house. If they are obviously damaged or on the ground, stay at least 10 meters back and notify your electric supply authority. Keep the number along with other emergency numbers near your telephone.
  • If your neighbors' power is also out, notify Oncor Electric power company.
  • Turn off all tools, appliances and electronic equipment, and turn the thermostat(s) for the home heating system down to a minimum to prevent damage from a power surge when power is restored. Also, power can be restored more easily when there is not a heavy load on the electrical system.
  • Turn off all lights, except one inside and one outside, so that both you and hydro crews outside know that power has been restored.
  • Don't open your freezer or fridge unless it is absolutely necessary. A full freezer will keep food frozen for 24 to 36 hours if the door remains closed.
  • Never use charcoal or gas barbecues, camping heating equipment, or home generators indoors. They give off carbon monoxide. Because you can't smell or see it, carbon monoxide can cause health problems and is life-threatening.
    Use proper candle holders. Never leave lit candles unattended and keep out of reach of children. Always extinguish candles before going to bed.
  • Listen to your battery-powered or crank radio for information on the outage and advice from authorities.
  • Make sure your home has a working carbon monoxide detector. If it is hard-wired to the house's electrical supply, ensure it has a battery-powered back-up.
  • Protect sensitive electrical appliances such as TVs, computer, and DVD players with a surge-protecting power bar.

Use of Home Generators

Home generators are handy for backup electricity in case of an outage, but must only be used in accordance with the manufacturer's guidelines. A backup generator may only be connected to your home's electrical system through an approved transfer panel and switch that has been installed by a qualified electrician. Never plug a generator into a wall outlet as serious injury can result when the current produced by the home generator is fed back into the electrical lines, and transformed to a higher voltage. This can endanger the lives of utility employees working to restore the power.

To operate a generator safely:

  • Follow the manufacturer's instructions
  • Ensure that the generator operates outdoors in well-ventilated conditions, well away from doors or windows, to prevent exhaust gases from entering the house
  • Connect lights and appliances directly to the generator. If extension cords must be used, ensure they are properly rated, approved cords
