Which Greek Cities Have the Most Power Outage Reports? Raw Counts for 2026
Athens, Heraklion and Piraeus lead Outage.gr's power-outage report counts in 2026. Here is the top ten, why raw counts are not a reliability ranking, and how to read your own city.

Key Facts
- Top power-report counts (to 20 Oct 2026): Athens 535, Heraklion 530, Piraeus 515, Peristeri 431, Volos 429
- Counts follow where people use Outage.gr, so a big city with many users will rank high either way
- We do not publish a per-capita or restoration-time ranking: the data cannot support one yet
- Every city has its own page with its report history and scheduled DEDDIE outages
A natural question is: which Greek city has the worst electricity? We would love to answer it, but the honest answer from our data is "we cannot rank cities by reliability yet". We can show you the raw numbers.
Power outage reports by city
| City | Power reports (to 20 Oct 2026) | City page |
|---|---|---|
| Athens | 535 | Athens |
| Heraklion | 530 | Heraklion |
| Piraeus | 515 | Piraeus |
| Peristeri | 431 | Peristeri |
| Volos | 429 | Volos |
| Larissa | 369 | Larissa |
| Chania | 354 | Chania |
| Ioannina | 329 | Ioannina |
| Patras | 301 | Patras |
| Kallithea | 184 | Kallithea |
Heraklion and Patras counts cover the wider municipal unit. Only places with 150 or more power reports are listed.
Why this is not a league table
- Users, not grids. A city appears high because many people there use Outage.gr and report. A city with a similar grid but fewer users appears low.
- No per-capita adjustment. We have not divided by population, because our user base is not spread evenly with population.
- Events concentrate counts. One big event can add hundreds of reports in a day. Crete's counts are heavily shaped by the 15–16 September storm outages and the 7 September fault (see the Crete blackout analysis).
- Reporting habits differ. Some communities report more than others.
What stands out anyway
- Attica contributes four of the top ten (Athens, Piraeus, Peristeri, Kallithea), which fits it being the most populated region.
- Thessaly has two (Volos and Larissa). In May and June, Thessaly was among the regions with the most reports.
- Crete has two (Heraklion and Chania), and those counts cluster in August and September.
How to read your own city
Open your city page to see its report history and the DEDDIE scheduled outages announced for it. If you want to see whether your area is affected right now, use the live map. And if you live in a place with repeated outages, the best response is practical: a UPS for your router and PC and a power-cut kit.
What would make a real ranking possible?
Three things: more reports spread across more places, enough reports marked as resolved to measure how long outages last, and a way to adjust for the number of users. We will publish a proper comparison as soon as the data can support it.
