Power Outage Preparedness for Greek Households: The Complete 2026 Guide

Power outages in Greece are a regular occurrence for most households — not a rare emergency. Our community data shows that the average Greek resident in a major city experiences a reported power disruption roughly four to six times per year, with higher frequency in suburban and rural areas. In island communities and mountainous regions, the frequency can be significantly higher.

This guide is designed to help you move from a reactive mindset (scrambling when the lights go out) to a proactive one (prepared for outages as a normal part of life in Greece). We cover equipment, planning, food safety, medical needs, and what to do immediately after power is restored.

Phase 1: Before an Outage Happens

### Build Your Outage Kit

A well-stocked outage kit costs €100–200 to assemble and will be used many times over. The essentials:

Lighting: - Two or three LED flashlights (not candles — open flames are a fire risk) - Spare AA and AAA batteries (keep them fresh; swap annually) - A headlamp is more practical than a handheld torch for extended use

Power: - A power bank (10,000 mAh or larger) to keep phones charged during extended outages. Charge it regularly. - Consider a second, larger power station (50,000 mAh+) if you work from home or have family members with powered medical needs

Communication: - A battery-powered radio (AM/FM) for news during extended outages when mobile networks may be congested - Keep a written list of key phone numbers: DEDDIE 11500, your local utility, family contacts, your doctor

Food and water: - Three-day supply of non-perishable food that does not require cooking: nuts, dried fruit, tinned goods with easy-open lids, crackers - Three litres of bottled water per person per day for three days (adjust upward in summer) - A manual can opener

First aid and medications: - Standard first aid kit - If any household member takes refrigerated medication (insulin, certain heart medications), consult your doctor now about safe storage during outages

### Protect Your Electronics

Voltage surges at the moment power is restored are the leading cause of appliance damage in Greece. Protecting your equipment proactively is far cheaper than claiming compensation after damage occurs.

Surge protectors (πολύπριζα με προστασία υπέρτασης): Install one on every circuit that connects to sensitive electronics — computers, televisions, audio equipment, gaming consoles. Look for models rated at 2,000 joules or higher, with a working indicator light. Replace them after any surge event, as their protective capacity is consumed by each event.

UPS (Uninterruptible Power Supply): For computers, routers, and any device where losing power mid-use is disruptive or dangerous, a UPS provides both surge protection and battery backup. A modest home UPS (600–1000 VA, €60–120) will keep a laptop and router running for 30–60 minutes during an outage — enough to save your work and have time to shut down properly.

Whole-house surge protector: Installed at your electrical panel by a licensed electrician, this provides the first line of defence against external surges entering your home from the grid. Cost: €150–300 installed. Particularly recommended for homes with expensive appliances or in areas with frequent grid events.

Refrigerators and appliances: Never connect a refrigerator to a regular surge protector power strip — the starting current of the compressor motor can trip the protection and leave the fridge disconnected. Use a direct wall connection or a dedicated appliance surge protector rated for motor loads.

### Know Your Risk Level

Check your city's page on Outage.gr to see your area's outage frequency and average restoration time. If your area shows more than five outages per month or average restoration times exceeding three hours, you are in a higher-risk zone and the investment in a UPS and surge protection is particularly justified.

Also check the scheduled maintenance section regularly. DEDDIE-planned outages are shown on your city's page and in the My Area section if you grant location access. Knowing about a planned outage in advance allows you to charge devices, fill water containers, and plan around the disruption.

Phase 2: When an Outage Begins

### Immediate Actions (First 5 Minutes)

1. **Check if it is just your home or wider.** Look outside at streetlights and neighbouring buildings. If only your home is dark, check your circuit breaker panel first.

1. **Unplug sensitive electronics immediately.** Computers, televisions, audio equipment, gaming consoles, and smart home devices should be unplugged. The voltage surge that often accompanies power restoration is more damaging than the outage itself.

1. **Keep refrigerator and freezer closed.** A refrigerator maintains food safety for approximately four hours with the door closed. A full, undisturbed freezer can hold safe temperatures for 48 hours; a half-full freezer for approximately 24 hours. Do not open them to check — every opening speeds temperature loss.

1. **Report the outage.** Call DEDDIE at 11500 and submit a report on Outage.gr. Reporting helps your community know they are not alone and creates documented evidence of the event.

1. **Charge your power bank and phone if they are not already charged.** Once the outage is confirmed as wider than your building, charge everything you have.

### If the Outage Extends Beyond 2 Hours

Phone management: Lower screen brightness to maximum darkness, disable Wi-Fi if you have mobile data, and close background apps. A fully charged modern smartphone can last 8–12 hours in low-usage mode.

Check on vulnerable neighbours. Elderly residents, those with young children, and anyone with powered medical equipment may need assistance. An extended outage in summer heat or winter cold can be medically dangerous for vulnerable people.

Food safety decisions. If a refrigerator has been at above 4°C for more than two hours, perishable items (meat, dairy, eggs, cooked food) should be discarded. When in doubt, throw it out — food poisoning risk is not worth it.

Winter cold: In winter, close off unused rooms and gather household members in one room to conserve body heat. Dress in layers. Avoid using gas cookers for heating — carbon monoxide risk in enclosed spaces.

Summer heat: An extended outage in summer without air conditioning is a genuine health risk for elderly residents and young children. Move to the coolest room. Stay hydrated. If the outage is prolonged and temperatures are extreme, consider going to a public space (shopping centre, library) with power.

Phase 3: When Power Returns

### First 5 Minutes After Restoration

1. **Wait before reconnecting.** Voltage may be unstable in the first few minutes after restoration. Wait at least five minutes before plugging anything back in.

1. **Reconnect one device at a time.** Starting with the most important. Do not immediately power on everything simultaneously — this can overload circuits and create a secondary disruption.

1. **Inspect for damage.** Before turning on appliances, visually check for any signs of damage: burn marks, melted plastic, unusual smells. If anything looks wrong, do not use it until it has been inspected by an electrician.

1. **Check the refrigerator temperature.** If the outage was more than four hours, verify the temperature before consuming refrigerated food.

1. **Report the restoration on Outage.gr.** If you submitted a report, mark it as resolved. This helps maintain the accuracy of the community map and contributes to the restoration time data that benefits everyone.

### If You Suspect Appliance Damage

Act immediately. You have 20 working days from the outage to file a compensation claim with DEDDIE under RAE Decision 1151A/2019. Do not repair or dispose of damaged appliances before DEDDIE's potential inspection. See our comprehensive compensation guide for the full process.

Special Considerations

### Residents With Medical Equipment

If anyone in your household depends on electrically powered medical equipment (oxygen concentrators, home dialysis machines, CPAP devices, insulin refrigeration), register this with DEDDIE. DEDDIE maintains a registry of medically dependent customers and is required to prioritise their restoration and provide advance notice of scheduled outages.

Contact DEDDIE in advance to register, and speak with your doctor about backup plans and how long your equipment can safely operate without power.

### Remote Work and Home Offices

For those working from home, even short outages represent lost productivity. A UPS for your computer and router, combined with a mobile data backup plan, covers the majority of short outages. For extended outages, a local coffee shop or library with public Wi-Fi and power provides a practical backup workspace.

Keep cloud backups current — if your computer powers off unexpectedly during a grid event, locally unsaved work can be lost even if the hardware survives.
