30 minutes until the power goes out: Do these things now

When a power outage is announced in advance, preparation is not only about the supplies you already have. What you do during the final minutes before the electricity is switched off can make the outage much easier to manage. This is especially useful during planned or rotating outages, when you may receive a short warning before your area loses power.

About 30 minutes before the outage, charge the devices you are most likely to need: your phone, power bank, rechargeable lights, radio and, if necessary, a laptop. Prioritize useful equipment instead of trying to run every appliance at once.

Around 20 minutes before the outage, think about water. Buildings that rely on electric pumps, pressure systems or private wells may lose water service when the electricity stops. Fill drinking bottles and a small container for basic needs. For a short planned outage, there is usually no need to store excessive amounts.

About 15 minutes before the cut, finish whatever is already running. Complete cooking if possible, save open computer files and stop washing machines or dishwashers in a controlled way. Avoid letting important tasks end simply because the power disappears.

Keep refrigerator and freezer doors closed from this point onward. Every unnecessary opening allows warmer air inside and shortens the time food remains safely cold.

During the final five to ten minutes, shut down sensitive electronics properly and unplug them if appropriate. Computers, televisions, gaming consoles and similar devices may benefit from being disconnected until power returns and stabilizes. Put a flashlight in one fixed, easy-to-reach location.

Tell everyone in the household what is about to happen. Children, older family members and guests should not be surprised when the lights suddenly go out. Keep mechanical keys accessible in case electric door releases, intercom systems or garage doors stop working.

When electricity returns, do not immediately switch on every major appliance. Give the supply a moment to stabilize and reconnect equipment step by step. During rotating outages, another interruption may follow later.

The biggest advantage of a scheduled outage is advance notice. A simple 30-minute routine turns the final moments before a power cut into an organized transition instead of a last-minute scramble.
