This calculator compares electricity tariffs from 12 providers in the Greek energy market.
Tariff data comes from energycost.gr (RAAEY, the Greek energy regulator)
and is updated monthly.
Each calculation includes a full breakdown of supply charges, regulated charges (transmission, distribution, YKO, ETMEAR),
and taxes (special consumption tax, special duty 0.5%, VAT 6%). Regulated charges are based on current RAAEY decisions
(E-189/2025 for transmission, E-99/2025 for distribution).
The electricity bill consists of three parts: supply charges (standing charge + energy per kWh), regulated charges (transmission, distribution, YKO, ETMEAR) which are the same for all providers, and taxes (special consumption tax, special duty 0.5%, VAT 6%).
What do the green, yellow, and blue tariff colors mean?
RAAEY (the Greek energy regulator) categorizes tariffs by color: Green means a fixed price with no adjustment clause, Yellow means a fixed price with an adjustment clause, and Blue means a variable price that follows the wholesale market.
What are regulated charges?
Regulated charges are set by RAAEY and are identical regardless of your provider. They include: System Usage Charges (ΧΧΣ) for transmission, Network Usage Charges (ΧΧΔ) for distribution, YKO (Public Utility Services), and ETMEAR (renewable energy levy).
How do I switch electricity provider in Greece?
Switching is free and done online. The new provider handles the process. No meter change or power interruption is needed. The switch typically takes 10-15 business days.
What is the night tariff?
The night tariff (time-of-use) offers lower prices during nighttime hours (usually 23:00-07:00). It requires a special meter that records day and night consumption separately. It is worthwhile if a large portion of your consumption happens at night.
