In December 2025, Ukraine significantly increased its electricity imports – by 54% compared to the previous month, to 639.5 thousand MWh, which was the highest figure since July 2024, the DIXI Group analytical center reported on its website on Wednesday, citing data from Energy Map.
“The increase in imports occurred against the backdrop of a deterioration in the power grid due to massive attacks by the Russian Federation on energy infrastructure and seasonal growth in consumption,” the center said.
During December, Russia carried out four massive attacks, targeting electricity generation, transmission, and distribution facilities. In particular, the attacks on December 6 and 23 led to a forced reduction in the generation of nuclear power plants, which provide more than half of Ukraine’s total electricity production. An additional factor contributing to the increased load on the power system was a significant drop in air temperature throughout the country, which led to an increase in energy consumption.
According to Energy Map, the increase in supply volumes was usually recorded the day after or two days after the shelling, during a period of reduced available generation and growing power shortages. Thus, after the attack on December 6, imports increased to 21.3 thousand MWh on December 7 (+18%) and to 32.6 thousand MWh on December 8 (+81%). A similar trend was observed after other massive strikes that took place on December 13, 23, and 27.
In December, Hungary accounted for the largest share of imports – 41%. Slovakia accounted for 21%, Romania and Poland for 18% each, and Moldova for 2%.
In December, the maximum transmission capacity of inter-state crossings for electricity imports increased from 2.1 GW to 2.3 GW. On average, the available transmission capacity was used at 37.4% during the month.
“Thus, December 2025 was the third consecutive month that Ukraine ended as a net importer of electricity,” DIXI Group emphasized.
On the other hand, Ukraine did not export electricity in December. The last time zero export volumes were recorded was in August 2024.
