Ukraine Fully Restores the Isaccea–Vulcănești Power Line

The 400 kV Isaccea–Vulcănești overhead power transmission line has been fully restored after damage caused by Russian drone attacks on energy infrastructure in southern Ukraine. This was announced on Saturday evening by the Ministry of Energy of the Republic of Moldova.

According to the ministry, the restoration works were successfully completed by the Ukrainian side, after which the line was tested under voltage. The tests confirmed that it is operating safely and stably. As a result, the transmission capacity of the interconnection has been restored and the reliability of electricity supply has been strengthened.

Despite the completion of the repair works, the Moldovan authorities continue to call on consumers to use electricity sparingly in order to avoid high bills and additional pressure on the national energy system.

It should be recalled that the Isaccea–Vulcănești 400 kV line is one of the key elements of Moldova’s power system and an important link with the European power grid. It was disconnected during the night of 23–24 March following damage caused by Russian attacks. In response, Moldova’s parliament introduced a 60-day state of emergency in the energy sector at an extraordinary session.

Earlier, Moldova’s Prime Minister Alexandru Munteanu and Minister of Energy Dorin Junghietu stated that the Republic of Moldova would cover the financial costs related to the repair works.

Comment by the Institute of Danube Research

 The restoration of the Isaccea–Vulcănești line goes far beyond a purely technical repair. It represents the stabilization of one of the critical energy corridors in the southwestern part of the region, helping ensure Moldova’s electricity security and supporting its integration into the European energy space. This case also demonstrates that the security of energy infrastructure in Ukraine’s border areas has a direct impact on the energy security of neighboring states. In a broader sense, it once again confirms the strategic interdependence of the countries of the Danube–Black Sea region in matters of critical infrastructure, energy resilience, and response to hybrid threats.
