Power Cut in Greece: Who Do You Call, DEDDIE or Your Supplier (PPC, HERON, Protergia…)?
Your supplier sends the bill, but DEDDIE runs the network. A plain-language guide to who fixes what in a Greek power cut, which number to call, what to have ready, and when to call 112 instead.

Key Facts
- DEDDIE operates the distribution network and fixes faults, whoever your electricity supplier is
- Your supplier handles billing, tariffs and contracts, not street-level faults
- DEDDIE fault line: 11500 (free, 24/7)
- Sparks, a downed cable or a fire: call 112 first and stay away
- A report on Outage.gr is not a report to DEDDIE: call 11500 as well
Many people call the wrong company when the lights go out. They ring the electricity supplier they pay every month, and the supplier cannot do anything about a fault in the street. This short guide explains who does what, so you reach the right place on the first call.
The two companies you deal with
- DEDDIE (ΔΕΔΔΗΕ) is the network operator. It owns and maintains the poles, cables, transformers and meters that bring power to your building. It fixes faults and announces planned works. You do not choose DEDDIE: it serves your area whoever you pay.
- Your supplier (PPC/ΔΕΗ, HERON, Protergia, Enerwave, ZeniΘ, Volton and others) sells you the electricity and sends the bill. You can switch supplier freely, and that never changes who fixes the network.
So a power cut is almost always a DEDDIE matter. A bill, a tariff or a contract is a supplier matter.
Who to call: quick table
| Situation | Call | Why |
|---|---|---|
| Whole street or area is dark | DEDDIE, 11500 (free, 24/7) | Network fault: only DEDDIE can fix it |
| Sparks, a downed cable, burning smell, fire | 112 first, then DEDDIE | Safety: stay well away |
| Only your flat is dark; neighbours have power | Check your breakers, then an electrician | Probably an internal fault |
| Meter or supply cable looks damaged | DEDDIE, 11500 | The meter and supply line belong to the network |
| You received a planned-outage notice | DEDDIE notice; check My Area | Planned works are announced by DEDDIE |
| A bill, tariff or contract question | Your supplier | Billing is the supplier's job |
| Appliance damaged when power returned | DEDDIE (report it the same day), then your insurer | See the compensation guide |
| Internet down but lights are on | Your internet provider | Different company again |
| No water | Your local water utility (EYDAP: 1022 in Athens) | See water disruptions |
What to do before you call
- Check your own panel. If a breaker has tripped, reset it once. If it trips again, stop and call an electrician.
- Look outside. If neighbours or street lights are also dark, it is a network fault.
- Check the map. Our outage map shows whether others nearby have reported the same thing.
- Have this ready: your address and a landmark, your supply number (it is on your bill), and the time the power went out.
- Ask for a reference number and write it down: you will need it if you ever claim for damage.
One important note about Outage.gr
Outage.gr is an independent community platform. It is not part of DEDDIE or any utility, and a report here does not notify DEDDIE. Community reports complement official fault reporting, they do not replace it. Call 11500 as well, and then report the outage on Outage.gr so your neighbours can see it too.
When it is not just a power cut
Sparks, burning smell, a downed line or a fire are emergencies: call 112 and keep everyone away. If someone is stuck in a lift, call 112 or the fire service (199) and do not try to force the doors.
Our full list of numbers for all utilities is in the emergency contact guide. To get ready for the next cut, see our UPS guide and the power-cut kit.
