Electricity prices in Greece remain dynamic – and for households and businesses, this means that flexibility is required. Since January 1, 2024, a new, color-coded tariff system has been in place to create more transparency: Blue stands for fixed tariffs, Green for the “Special” tariff model with a price announced monthly in advance, Yellow for variable tariffs and Orange for future dynamic tariffs, the price of which can fluctuate hourly based on the wholesale market (prerequisite: smart meter). This structure was introduced by the Ministry of Environment and Energy to make comparisons easier and shorten decision-making processes. ΥΠΕΝ+1Η ΝΑΥΤΕΜΠΟΡΙΚΗ
At the same time, the distribution network operator DEDDIE/HEDNO is pushing ahead with the rollout of smart meters so that flexible and dynamic pricing models can function at all. Official announcements and industry reports speak of a significant acceleration until 2025 and beyond – the goal is a large-scale coverage that paves the way for time-variable and dynamic tariffs. For consumers, this means that anyone with a smart meter will be able to react more actively to price signals in the future. energypress.euIskraemeco Corpo
Another important component is the February 1, 2025 effective new two-zone-based low-tariff system: In addition to the nightly off-peak phase, there is now also a midday discounted zone. In winter (Nov.–Mar.), 12:00–15:00 and 02:00–05:00 are generally considered low-tariff, in summer (Apr.–Oct.) 11:00–15:00 and 02:00–04:00. The aim is to shift consumption to times of high generation – especially from photovoltaics – and thus reduce costs. Anyone who places large consumers (e.g. boilers, washing machines) in these time windows can save noticeably. ΔΕΔΔΗΕ+1ΔΕΗ
How are prices developing? After the extreme swings in 2022/23, the situation remained volatile. At times, the government activated targeted subsidies to ease the burden on households; depending on wholesale market conditions, such measures were reactivated in certain months. This highlights how strongly end-customer prices still depend on wholesale markets and the weather—and why choosing a tariff each month has once again become an active issue for many customers.

What is changing with the tariffs themselves? Officially, the four-colour system applies, but the regulator (RAAEY) is working on further adjustments. Public debate is focusing on new tariff categories and a rebalancing of the existing models to sharpen price signals and reduce misunderstandings among consumers. This includes, among other things, considerations around more flexible (“red”) options alongside blue, yellow and orange; in some cases, there is even talk of phasing out the green model. Important: These are proposals/procedures under consultation, not final adopted rules—still, the debate shows where things are heading: away from flat rates and towards usage- and time-dependent pricing.
