Electricity Prices in Greece, October 2026: Green Tariffs Compared and How to Switch Supplier

Electricity prices in Greece changed again on 1 October. After wholesale prices rose by about 17% in September, most suppliers raised the price of their floating "green" tariffs. A few held theirs. The gap between the cheapest and the most expensive is wide, and the headline price per kWh does not tell you what you will pay. This guide lays out the October numbers from published price lists and shows how to check your own.

October 2026 green tariffs at a glance

Insider put the average of green tariffs at close to 24 cents per kWh in October. The cheapest and dearest on the list above differ by more than 12 cents per kWh.

Watch out for tiered tariffs

Two of the plans in the table are tiered: the headline price applies only to the first 100 kWh a month, and the price rises sharply above that.

For a household using a typical 300 kWh a month, those prices matter a great deal.

What does 300 kWh cost?

Energy charge only, October 2026. The first three figures are as calculated by biskotto.gr; the others are our arithmetic from the published rates (flat rate × kWh, or the two tiers for tiered plans).

Same electricity, same month, a difference of nearly €48 in energy charges alone. Fixed fees, consistency discounts and regulated charges come on top.

Fixed-price plans

PPC kept its promotional fixed-price blue tariff, myHome Online, at €0.115 per kWh in October with a €3.50 fixed fee. At 300 kWh that is about €38 in energy plus fixed fee, by our arithmetic. Fixed plans lock the price for the contract period, which protects you against monthly increases like this one, but they come with conditions (for example, how you apply and pay, and how long you must stay). Read the conditions before you sign.

Five checks before you switch

1. What is the real monthly bill? Add the fixed fee and apply the discounts to your own kWh, not the average.
2. What are the conditions? "Consistency discount" (έκπτωση συνέπειας) and similar discounts depend on paying on time or other rules.
3. Is it tiered? If you use more than 100 kWh, a tiered plan can cost double.
4. Is it fixed or floating? Floating prices reset monthly. Fixed ones lock in a price for a period.
5. What are the exit terms? Check for early-termination fees on fixed plans.

How to switch

Switching is done by your new supplier, normally online with a recent bill and your supply number, and your old supplier does not need to be told. The network stays the same: DEDDIE keeps running the poles and meters and fixing faults whoever you pay (see who to call in a power cut). Switching does not change the quality of supply.

Where to compare

A comparison tool does the arithmetic against your own consumption. Pricefox compares electricity and gas plans across suppliers:

You can also use Allazorevma.gr, a comparison site, or look at a supplier directly, for example ZeniΘ. We link to these sites and may earn a commission if you sign up through them, at no cost to you. The tables above include every supplier whether or not we have a link. As the table shows, ZeniΘ's Power Home Start plan is tiered and expensive above 100 kWh, so look at its other plans and compare the total cost before choosing. See also our provider overview.

Prices and outages are different problems

A cheaper supplier will not make the lights stay on. Outages are about the network, which is DEDDIE's job, and you cannot choose it. What you can do is prepare: see our guides to a UPS for your home and a power-cut kit, and report problems on Outage.gr.
