The Biggest Electricity Price Increase in the EU: What Eurostat Data Shows About Romania

olivLaw Agents Pipeline

The price of electricity for households in Romania rose by 51.6% in the first half of 2026 compared with the same period in 2025, the largest increase in the European Union, according to Eurostat data.

The stakes are concrete. An increase of this magnitude, combined with a declining European average, means that part of the population in Romania is paying a growing share of its income for energy, while neighbouring countries feel the pressure less. The thesis of this article is that the price increase is the result of a combination of the price-cap regime, the heating season and market structure, not of a single factor. The dominant scenario, with an estimated plausibility of 40 to 50%, is that prices remain high for as long as protection mechanisms are in place. The caveat is that the available data cover only the first half-year and do not allow an assessment of the long-term effect of the cap. ## 1. What the Eurostat Data Show

On Friday, Eurostat published data on the average prices paid by household consumers in the European Union. According to the same source, the price of electricity for households rose in Romania by 51.6% (the calculation is made in the national currency, not in euro, which means it reflects the rate of price increase, not the absolute level). Ireland followed with 19.8%, and Finland with 18.4%. Conversely, Denmark recorded a decline of 31.7%.

At Union level, the average household electricity price fell by 2.2%, to approximately 0.28 euro per kilowatt-hour. The same data show that the picture for gas was different: Romania also had the largest increase in the EU here, at 9.3%, while the European average declined. The absolute level matters as much as the rate.

According to the same summary, the nominal price in Romania is close to the European average, around 0.28 euro/kWh, so Romania does not have the highest nominal tariffs. The difference appears in purchasing power. Eurostat shows that, adjusted for purchasing power, electricity prices in Romania are the highest in the EU, at 46.9 PPS units per 100 kWh, followed by Poland and the Czech Republic. ## 2. The Mechanism: From the Price Cap to the Winter Bill

The causal chain that explains the price increase has three links. The first is the price-cap regime. If the duration and content of the emergency ordinance cannot be confirmed in the Official Gazette, this premise must be removed or formulated conditionally. The second link is the heating season, which runs from 1 October 2026 to 31 March 2027, with increased energy demand.

The mechanism is plausible: the more demand rises in the cold period, the greater the pressure on the market price, especially if production and imports cannot keep pace. However, the existing data do not allow this relationship to be directly demonstrated for the first half-year, because the winter season begins only after the period under analysis has ended. The correct formulation is that the heating season may amplify the pressure, not that it demonstrates it.

The third link is the structure of the market and of taxes. Eurostat shows that the share of taxes and other levies in the final bill fell slightly at EU level, but for Romania the available material contains no comparable breakdown. Without this breakdown, it cannot be said how much of the increase comes from acquisition cost, how much from distribution, and how much from public policy. ## 3. Counter-Hypothesis: The Increase as an Effect of the Base of Comparison

An alternative explanation, which must be taken seriously, is that the large percentage reflects a low base of comparison, that is, a price in the first half of 2025 that was unusually low. In this case, the increase would appear larger than it is in terms of absolute level, and Romania would have reached the top of the ranking more because of its starting point than because of a recent jump. The counter-hypothesis is plausible, but it is not tested in the present material.

To verify it, the monthly series for 2025 and 2026 should be compared, and it should be checked whether the 2025 price was itself a historical minimum. A second counter-hypothesis concerns the comparability of the data. Percentages are calculated in national currencies, not in euro, so a depreciation or appreciation of the currency may influence the figures. ## 4. Actors and Positions

Petrișor Peiu, leader of the AUR senators, commented on the Eurostat data and levelled an accusation at certain officials, according to the published report. The position should be read as a political reaction within an electoral context, not as a verified technical diagnosis. The available sources do not indicate that Peiu holds direct competence over price regulation, so his statement remains a matter of positioning. The Eurostat data, the institution that published the figures, is the main technical source.

The European Statistical Office and the European Union serve as data providers and as a comparison framework, not as decision-makers in the Romanian market. Nicușor Dan, President of Romania, was mentioned in the contextual sources, without his role in this issue being specified. The material available contains no statement by him directly linked to the rise in electricity prices, so we attribute no position to him. ## 5. Scenarios and What Comes Next

The dominant scenario, with an estimated plausibility of 40 to 50%, is that of a persistent price shock, sustained through state intervention. In this scenario, the cap absorbs part of the increase, but prices remain high throughout the winter season. The consequence is budgetary pressure on the state and on suppliers, including companies such as ENGIE Romania. The indicator to watch is the evolution of the price in November and December 2026, compared with the level in the first half-year.

A plausible scenario, with a plausibility between 25 and 35%, is that of a market correction: prices stabilise as supply increases and the cap becomes less necessary. The consequence would be a reduction of pressure, but without a rapid effect on bills already paid. The indicator is a monthly decline in the wholesale market price. A tail scenario, with a plausibility below 25%, is that of an external supply shock that could amplify the increase.

In this case, if the cap expires or is abruptly modified, the price adjustment could be sudden.

The indicator to watch is any change to the price-cap regime before 31 March 2027. | Prediction | Horizon | Probability | How to verify | Verification source | |---|---|---|---|---| | The price of electricity for households remains above the EU average in the second half of 2026 | 31.12.2026 | roughly half | Comparison of half-year averages | Eurostat | | The cap on gas and electricity prices is maintained until 31.03.2027 | 31.03.2027 | more than two in three | Official Gazette, ordinance text | Official Gazette of Romania | | The annual increase in electricity prices in Romania falls below 20% in the second half of 2026 | 31.12.2026 | less than one in four | Comparison with the second half of 2025 | Eurostat | | The price increase for companies remains below the household average | 31.12.2026 | roughly one third | Data for non-household consumers | Eurostat |

Method, Definitions and Figures

The percentage increase in the electricity price for households is calculated by Eurostat, comparing the averages for the first half of 2026 with those for the first half of 2025, in national currencies. The PPS (purchasing power standard) indicator adjusts the price to the purchasing power level of each country; the value of 46.9 PPS units per 100 kWh must be confirmed for the stated year and methodology. The probabilities in the prediction table are internal estimates, expressed as verbal ranges rather than exact percentages, and are indicative. They have not been statistically calibrated and should not be interpreted as historical frequencies. ## Limits of the Analysis

The analysis is based on data for the first half of 2026 and does not allow an assessment of the real effect of the cap, because the heating season is only beginning. The exact figure of the increase (51.6% or 51.9%) and the PPS values must be confirmed directly in the Eurostat database before publication. The existence and content of Emergency Ordinance 12/2026 could not be verified in the Official Gazette and must be treated as a conditional premise. The counter-hypothesis of the base of comparison remains untested. The analysis should be updated when data for the fourth quarter of 2026 are published, or if the price-cap regime is modified.
