Prices in the wholesale electricity market may be falling, driven by the high penetration of renewables, but the benefit does not reach the retail market. Consumers in Greece paid the third highest price of kilowatt-hour in Europe in 2025, and the costliest in terms of purchasing power.
In 2025, retail rates in terms of nominal prices and purchasing power, were, respectively, €36.50 per megawatt-hour (or 29.3%) and €72.60/MWh (57.8%) more expensive than the European average.
The vast majority of consumers with green tariffs (58% at the end of 2025) paid an average of 13.3% more per KWh than blue tariffs and 27.3% more than yellow tariffs, which were the cheapest option in the 2024-2025 two-year period.
According to the analysis of colored tariffs by Green Tank, based on data from RAAEY, if all consumers with green tariffs chose the cheapest yellow tariff every month, they would reduce their electricity costs by €1.23 billion over the two-year period.
The conclusions of the Green Tank report on the retail energy market in Greece, based on both Eurostat and RAAEY data for 2024-2025, reveal the disproportionate costs that consumers in Greece pay compared to consumers in the rest of Europe, especially when energy poverty in the country remains at very high levels.
