Greek electricity consumers are shifting toward variable yellow tariffs following energy market instability caused by the war in the Middle East, according to official data.
Official figures from the Regulatory Authority for Waste, Energy and Water (RAAEY) covering the first half of the year show yellow tariff market shares rising in May and June as fixed blue contracts became less competitive.
Under Greece's standardized electricity tariff system, green products represent regulated monthly plans, blue contracts provide fixed pricing over set terms, yellow products offer variable rates indexed to wholesale market prices, and orange plans deliver dynamic pricing for customers with smart meters.
During the first four months of the year, consumers continued moving away from green-regulated options and toward fixed blue tariffs. That trend stalled in May and June, when the market share for fixed plans remained relatively stable, green tariffs continued losing subscribers, and variable yellow tariffs recorded gains following the outbreak of conflict in late February.
Tariff market shares
RAAEY data shows commercial customers adopted variable yellow contracts at higher rates than households during the first half of the year. In June, yellow tariffs accounted for 18.38% of commercial power plans compared to 15.21% among residential accounts.
Fixed blue tariffs secured 25.42% of the business market in June, while residential uptake reached 31.62%. Green tariffs retained the largest portion of both market segments, standing at 53.19% for commercial users and 53.17% for households.
Meanwhile, dynamic orange tariffs failed to attract consumer interest. RAAEY recorded only 15 residential customers nationwide enrolled in orange plans during the six-month period.
Rising prices drive shift
The shift toward yellow tariffs comes after variable contracts proved cheaper than competing options during the previous winter, although consumers cannot know total costs in advance compared to fixed plans.
At the same time, price increases on fixed blue plans reduced their competitiveness during the current year. In 2025, fixed blue tariffs were available from as low as 9 cents per kilowatt-hour, but current starting prices have climbed close to 11 cents per kilowatt-hour, with average rates standing even higher.
