According to Energy Map, during 28 September - 4 October, electricity exports increased by 75.6% compared to the previous week, reaching 147.0 GWh, while imports decreased by 10.6% to 12.3 GWh. Overall, electricity exports exceeded imports twelvefold. This was the highest weekly export volume since September 2025. On 2 October, the highest daily export volume over the same period was also recorded, at 26.1 GWh.
The key factor behind this trend was the return of sunny weather. The reporting week was clearer than the previous one, while temperatures remained almost unchanged. This is reflected in the pattern of cross-border electricity flows: during daily hours, from 09:00 to 18:00, exports increased by 170.4%, compared with a 46.5% increase during the remaining hours. The increase was driven by higher solar generation under clear weather conditions, which affected the power system balance during daytime hours and, consequently, the dynamics of cross-border electricity flows.
During the reporting period, Ukraine’s power system was balanced primarily through domestic generation and electricity imports. On 30 September, emergency power outages were imposed in Kyiv city, Kyiv, Chernihiv, and Zhytomyr regions due to equipment overload caused by shelling. In the Kyiv region, scheduled hourly outages were also implemented from 18:00 to 24:00 that day. For 1 October, consumption restrictions for households and industrial consumers had been planned in certain regions, but these measures were subsequently cancelled. At the same time, consumers in Kyiv city, Kyiv, and Zhytomyr regions were urged to use electricity sparingly during the evening hours.
Cross-border flow data indicate the localized nature of these restrictions. Even during the 18:00–24:00 period on 30 September, Ukraine remained a net exporter of electricity, with exports totaling 4.1 GWh compared with 1.1 GWh of imports. This indicates that the outages resulted from damage to and overloading of equipment in specific regions rather than from an overall power capacity deficit across the system.
Imports by country*:
- Hungary – 9.0 GWh (73.1%);
- Romania – 2.1 GWh (17.2%);
- Poland – 1.2 GWh (9.5%);
- Moldova – 0.02 GWh (0.2%).
Electricity imports decreased from Poland by 59.2%, from Moldova by 57.1%, and from Romania by 23.1%. Hungary was the only destination where imports increased, by 11.1%. No electricity imports from Slovakia were recorded for the fourth consecutive week.
Exports by country*:
- Hungary – 73.6 GWh (50.1%);
- Moldova– 44.9 GWh (30.5%);
- Romania – 28.3 GWh (19.3%);
- Poland – 0.2 GWh (0.2%).
Electricity exports increased by almost the same rate across three destinations: by 76.8% to Romania, 76.1% to Hungary, and 75.8% to Moldova. Exports to Poland were the only ones to decline, by 43.2%, albeit from relatively low volumes. There were no electricity exports to Slovakia.
