If the power goes out, the first thing you need to do is call the power distributor. It would be best if you were caution and had already all the important numbers saved in your phone, including numbers of utility companies and a local Westminster electrician. Ask how long the power failure will last until the reasons for its production are identified and repaired.
Once you know how long it will take, you can approximate if you have enough resources so that the lack of electricity does not cause you too much trouble, for example with heating the water or with the indoor thermal comfort. If you find out that the power outage will take several hours take the appropriate measures: do not open the windows to prevent heat loss and save the battery from your phone or laptop to have them available in case of emergency.
If you want to play safe, and the power outage to not to cause you any inconvenience, one of the objects that prove to be very helpful is an electric current generator. Although it involves a larger investment than for flashlights, at a time of crisis it is extremely useful and will get you out of difficult situations. You can opt for a small, portable generator that provides enough electricity for a home.
