Greek Electricity Tariffs for May: Stability Amidst Uncertainty

As Greece navigates May 2026, the energy market is characterized by a cautious wait-and-see approach, influenced by significant geopolitical uncertainty. While wholesale electricity prices on the Energy Exchange have seen a modest decrease of 6.6% to €88.72/MWh, the majority of suppliers have opted to keep their 'green' tariff rates unchanged. This decision reflects a strategic move to build a financial cushion against potential price surges stemming from the ongoing crisis in the Middle East and the anticipated increase in energy consumption during the summer months.

Consumers will find a detailed breakdown of electricity tariffs across various providers for May. Public Power Corporation (DEI) maintains its green residential tariff (Γ1/Γ1Ν) at €0.138/kWh, with its flexible yellow tariff (myHome4All) slightly lower at €0.1378/kWh. Protergia, the second-largest supplier, holds its green tariff steady at €0.159/kWh. HERON keeps its BASIC HOME green tariff at €0.14760/kWh while slightly reducing business tariffs. NRG maintains its green tariff at €0.199/kWh.

The most significant adjustment comes from Elin Oil, which has surprised the market with a substantial 21% reduction in its green tariff, bringing it down to €0.1346/kWh from €0.17016 in April. VOLTON has made a minor adjustment, with its green tariff now at €0.18635/kWh, a slight decrease from the previous month. This landscape of stable, and in one case reduced, pricing offers a degree of predictability for Greek households and businesses amidst a volatile global energy environment, though the underlying geopolitical risks remain a key concern for future price stability.
