The latest energy data for the first half of 2026 released by the Romanian National Bureau of Statistics presents a highly contrasting set of industry signals. The overall energy production and terminal consumption are shrinking synchronously, while green electricity is rising sharply against the trend. Cross border electricity exports are expanding synchronously, and the energy structure transformation in Southeast Europe is advancing at an unexpected speed.

Structural contraction occurs simultaneously at both ends of supply and demand

In the first half of the year, Romania's total primary energy reached 15.502 million tons of oil equivalent, a year-on-year decrease of 4.1%. Domestic production fell by 2.6% year-on-year, and energy imports fell by 5.5% year-on-year. The overall consumption of terminal electricity decreased by 3.3%, with the largest decline in residential electricity consumption reaching 11.8%. The electricity consumption in the economic sector only slightly decreased by 0.6%, and the electricity consumption for public lighting fell by 4.6% year-on-year.

The overall weakening of energy demand has not dragged down the basic infrastructure of electricity supply. In the first half of the year, the total amount of electricity resources in China increased slightly by 1.1%, reaching a total scale of 34.691 billion kilowatt hours. The internal structure of the electricity supply side is undergoing a drastic differentiation and adjustment.

Accelerating the transition between new and old forces in power generation structure

The output of traditional base load power sources continues to shrink, with a year-on-year decrease of 5.9% in thermal power generation and a significant decrease of 11.7% in nuclear power generation. The combined production reduction of the two types of traditional power sources exceeds 1.08 billion kilowatt hours. Renewable energy represented by hydro, wind, and solar power has exploded comprehensively, with photovoltaic power generation increasing by 42.1% year-on-year, hydropower increasing by 17.9% year-on-year, wind power increasing by 9.0% year-on-year, and the total output of the three types of green power increasing by over 2.37 billion kilowatt hours.

The increase in new energy not only completely fills the supply gap left by traditional base load power sources, but also creates a large amount of surplus electricity, allowing Romania's electricity supply to achieve a slight increase in the total supply scale despite the overall demand contraction. Romania's energy data for the first half of 2026 is released, with green electricity significantly replacing traditional base load power sources, and cross-border electricity exports achieving double-digit growth simultaneously

Power grid and cross-border channels undertake transformation spillover

The high proportion of green power grid connection has begun to show practical impact, with a significant year-on-year increase of 16.4% in power grid technical losses in the first half of the year, and an additional loss of over 400 million kilowatt hours. This data directly reflects that the original transmission and distribution architecture is facing the impact of high proportion intermittent energy, and the demand for flexible upgrading of the power grid is urgent.

Against the backdrop of reduced local terminal consumption, the newly added green power increment has not been converted into wind and solar power curtailment, but is directly transmitted outward through cross-border interconnection channels. In the first half of the year, electricity exports increased by 11.4% year-on-year, with nearly 790 million kilowatt hours of newly exported electricity. Cross border power networks have become the core buffer carrier for absorbing the overflow of local green power. Keywords: green electricity, energy production

A seemingly contradictory set of statistical data precisely outlines the real stage of Romania's energy transition. Traditional power sources are accelerating their exit, new energy is rapidly filling the gap, and cross-border channels are taking over surplus production capacity. The electricity market pattern in Southeast Europe is being completely reshaped by this green power growth force.Editor/Cheng Liting
