Power Outage Statistics in Greece

Greece experiences thousands of reported utility outages every year. Outage.gr has been collecting crowdsourced data since 2025, building one of the most detailed public datasets on utility reliability across the country. This guide explains what the data shows, which regions are most affected, and how to use outage statistics to protect yourself.

What Outage.gr Data Tells Us

Every report on Outage.gr includes a utility type (power, water, or internet), a precise location, a timestamp, and community confirmations. Reports expire automatically after one hour of inactivity — this means only active, recently verified outages stay on the map, keeping the data clean and current. Power outages consistently make up the majority of reports, followed by internet and water. This reflects both the frequency of power grid events and the fact that power outages are immediately noticeable — unlike slow pressure drops in water supply.

Most Affected Regions

Outage distribution in Greece is influenced by infrastructure age, weather exposure, and population density. Remote island communities and mountainous areas often experience longer restoration times due to limited maintenance access. Urban centres like Athens (Attica) have more frequent reports simply because of population size, but restoration times tend to be shorter. During extreme weather events — such as heat waves in summer or storms in winter — outage frequency spikes nationally. The Outage.gr map reflects these events in real time, with clusters of reports appearing across affected regions simultaneously.

Average Restoration Times

Based on community data, most power outages in urban Greek areas are resolved within 1–3 hours. DEDDIE's contracted response time for unplanned faults is typically within a few hours, though this varies by region and time of day. Scheduled maintenance outages have fixed start and end times and are published in advance — Outage.gr imports these automatically. Extended outages (over 6 hours) are less common but more likely during major infrastructure failures, storms, or wildfire events. The average restoration time visible on each city page is calculated from resolved reports — the more data a city has, the more reliable its average.

How to Use This Data

• Check your city page to see local outage trends and average restoration times
• Use the My Area section to see scheduled DEDDIE maintenance near your exact location
• If your area has frequent outages, document them on Outage.gr to build evidence for consumer complaints
• Historical outage data from Outage.gr can serve as supporting documentation for compensation claims filed with DEDDIE
• City pages are updated daily as new reports come in and old ones expire

Frequent Outages and Your Rights

If your area experiences repeated power outages causing appliance damage, you have legal rights under Greek consumer law and RAE Decision 1151A/2019. Each incident must be reported to DEDDIE at 11500 and a compensation claim filed within 20 working days. The maximum compensation per incident is €600. Outage.gr certificates — available in the Evidence section — can serve as timestamped supporting documentation when filing claims, showing the date, time, and community-verified scope of each outage.
