Power Outage Statistics in Greece: What Our Community Reports Reveal

Since launching in early 2026, Outage.gr has grown into a crowdsourced utility outage tracker for Greece. In our first months, the community has submitted more than 1,500 verified reports covering power, water, and internet disruptions from Athens to the smaller Aegean islands. This analysis examines what that early data reveals — and is honest about what it is still too soon to claim.

The Scale of the Data

As of mid-2026, our database holds more than 1,500 community-verified outage reports, backed by over 650 neighbour confirmations. Every entry was submitted anonymously by a resident, confirmed by at least one neighbour using the "Me Too" button, and timestamped to the minute. The dataset is young and growing, so we treat it as an emerging picture rather than a definitive census.

Power outages dominate overwhelmingly: roughly 97% of all reports concern electricity, with internet disruptions and water supply problems making up the small remainder. This skew partly reflects how immediately noticeable a power cut is compared with a slow drop in water pressure, and partly reflects where our early community has been most active.

Frequency: How Often Do Outages Occur?

In recent weeks the platform has been receiving on the order of 300+ new community reports per week. We deliberately avoid projecting annual or seasonal trends yet — the site is only months old, so we do not have a full year of data to make claims about summer heatwave peaks or winter storm seasons. As the dataset matures across a full calendar year, we will publish seasonal analysis grounded in real observations rather than estimates.

The areas with the highest number of reports so far are large population centres such as Athens, Thessaloniki, and Patra — a reflection of where most residents (and therefore most reporters) are, rather than proof that these cities have the worst infrastructure.

Duration: How Long Do Outages Last?

Measuring restoration time requires reports that have both a start timestamp (the original submission) and an end timestamp (when the reporter marked it resolved). Only a minority of reports are formally marked resolved — most expire naturally from the map after one hour of inactivity — so our resolved-time sample is still small. For that reason we are not yet publishing precise regional medians: with a few dozen resolved reports, any per-city figure would be statistically unreliable.

For context, DEDDIE's own published service-level targets call for restoration within four hours in the large majority of low-voltage network faults. As our resolved-report sample grows, we will compare community-observed restoration times against those targets and publish the results transparently, including sample sizes.

Why Seasonal Claims Have to Wait

It is tempting to describe summer heatwave peaks and autumn storm spikes, and those patterns are well documented in Greece's grid more broadly. But Outage.gr itself has not yet operated through a full calendar year, so we will not pretend our own data proves them. Rather than publish seasonal percentages we cannot back, we are letting the dataset run through summer, autumn and winter, and will report the real seasonal curve once we have observed it. We would rather be useful and honest than impressive and wrong.

Power, Internet and Water

The overwhelming majority of reports — around 97% — concern electricity. Internet and water reports together make up only a few percent. Some internet reports are likely secondary effects of power cuts (when a substation or a home router loses power, the connection drops too), which is hard to separate from genuine ISP-side failures using community reports alone. As the volume of internet and water reports grows, we will look at provider-level and area-level patterns, but at current sample sizes we deliberately avoid naming specific providers as the "worst" — that would not be a fair or statistically sound claim.

Implications for Residents

Even at an early stage, the data is practically useful. If you live in an area that shows repeated outages — visible on each city's dedicated page on Outage.gr — you have a stronger basis for consumer-protection action.

Individual residents whose electrical appliances are damaged by a power outage may be entitled to compensation of up to €600 per incident under RAE Decision 1151A/2019. The key requirement is reporting the outage to DEDDIE at 11500 on the day it happens and filing a formal claim within 20 working days. A timestamped Outage.gr report can serve as supporting documentation.

Residents who believe their area has systemic reliability problems can escalate complaints to RAAEY (the Regulatory Authority for Energy), citing the documented frequency of outages. A pattern of community reports covering the same area over multiple months provides useful supporting evidence.

Methodology Note

All figures here come from Outage.gr's own database and are stated as of mid-2026. Our data represents community-reported and community-verified outages — it captures disruptions that affected real residents and were confirmed by neighbours. It does not capture outages that went unreported, or very brief ones (under ~10 minutes, which rarely attract reports), so it should be read as a lower bound on actual outage frequency, not an upper bound. Because the platform is young, sample sizes for resolved-time and seasonal analysis are still small, and we say so explicitly rather than dressing estimates up as findings. City-level statistics update in real time on each city's page.
