Greece’s 2025 electricity providers show mixed price rankings

The Regulatory Authority for Waste, Energy and Water (RAEE) released its first annual “radiography” of the Greek electricity market for 2025. The analysis shows that price competitiveness varies by tariff type and consumption level, preventing a single “cheapest” supplier label.

For a typical household consuming 330 kWh per month, the lowest monthly charge was the variable‑rate Yellow One Home 2 from Irona at €29.95 in September. Over the full year, the most affordable fixed‑rate product was Protergia’s Value Secure 12M, with an annual competitive charge of €510. When averaging across all tariff categories, ELINoil recorded the lowest yearly charge at €50.79, followed by Protergia (€51.09) and DEI (€51.82). The highest average charges were posted by Solar Energy (€69.66), Volton (€59.86) and OTE Estate (€57.17).

Fixed‑rate tariffs tended to be cheaper overall: ELINoil (€42.65), Irona (€43.32) and Volton (€44.76) led the list, yet the same firms appeared among the most expensive in variable tariffs. DEI, third‑most‑priced in fixed tariffs, ranked second‑cheapest in variable tariffs and cheapest in special tariffs. For higher consumption (660 kWh/month) Protergia remained the cheapest (€97.97), with ELINoil (€99.94) and Enerwave (€101.91) close behind. Similar patterns were observed for small‑business customers.

The report concludes that consumers must assess providers by specific tariff categories and usage levels rather than relying on a single “cheapest” ranking.
