Greece Electricity Tariff API

How a household electricity price is built in Greece

Greece runs the simplest network structure in Europe: one nationwide distribution operator serves every address, including the islands, so there is never a question of which local grid company applies, and the regulated part of the bill is identical everywhere. Supply is liberalized among around eighteen suppliers, though the former state monopoly still holds most household connections. The distinctive feature is a legally mandated four-colour product classification that every offer must declare itself into.

What a household bill is made of

1. 1

   Energy

   The national day-ahead market is the reference. What a household actually pays depends on its product colour: blue products pass through a contractually fixed rate; green products pass through a rate the supplier announces for each coming calendar month; yellow products apply a published indexation formula over a wholesale reference; orange products pass the hourly clearing price through directly.

2. 2

   Network charges

   Two regulator-set components, both national. The transmission charge is a pure per-kWh rate for non-telemetered low-voltage customers — the category households fall in — while telemetered customers pay a capacity charge instead. The distribution charge has three parts: a fixed charge per kilovolt-ampere of connection capacity (not on consumption), a small per-kWh variable charge, and a per-meter charge. The distribution revenue requirement is deliberately weighted heavily toward the fixed leg.

3. 3

   Taxes and levies

   A public-service-obligation charge set directly in statute and stepped by four-monthly consumption, with separate day and night bands — it funds uniform island pricing, the large-family tariff and the social tariff. A renewables levy funds the special renewable-support account. An excise duty applies at a reduced domestic rate. Finally a special 0.5% duty is charged on the value of the electricity consumed plus the excise — the one Greek levy that is proportional rather than per-kWh, and unusually it is not subject to VAT.

4. 4

   VAT

   6%, the reduced rate: electricity is listed in the reduced-rate annex of the VAT code, so the 24% standard rate does not apply. VAT covers the energy, network, public-service, renewables and excise lines but not the 0.5% duty or the municipal items.

Regulation shaping the price

• Every supply product must legally be declared in one of four colour categories, which fixes how its price may move — this is a statutory classification, not marketing.
• The green category is Greece’s largest and most distinctive: a semi-floating price that each supplier announces for the coming calendar month and then holds fixed for that month, effectively resetting twelve times a year.
• Public-service and renewables charges are national and identical for every supplier, so the whole non-energy stack can be reconstructed from a household’s consumption and connection capacity.
• Net billing replaced net metering for new installations: generation is netted against consumption in real time and the surplus is paid at the wholesale day-ahead price, not credited at a retail-equivalent rate. Pre-existing net-metering contracts continue under their original terms.
• Two non-electricity items ride on the same bill — a public-broadcaster levy and municipal charges assessed on floor area — which belong on the bill but never in a per-kWh price.
