This is war: Europe’s energy security depends on full synchronisation of Ukraine and Moldova with the EU electricity system

28 February 2022

Since 24 February, the Ukrainian and Moldovan power systems have been operating in isolated mode. The planned isolated mode test is part of their preparation to fully synchronize with the interconnected power systems of the synchronous area of Continental Europe. The Ukrainian and Moldovan systems proved to be stable despite the extremely challenging conditions caused by the Russian invasion. But the Ukrainian and Moldovan power systems continue to be under threat, and so do the lives of citizens depending on those systems.

Ensuring uninterrupted electricity supply in Ukraine and Moldova is paramount also for the safety of citizens in the European Union and the other Energy Community Contracting Parties. Continuous operation of the system must be ensured to maintain the safety of Ukraine’s nuclear power plants. Moreover, a blackout of the Ukrainian system would result in a blackout in Moldova too. Against these serious threats, the accelerated synchronisation of the Ukraine and Moldova seems to be the best way to prevent a possible blackout of their power systems due to prolonged armed conflict, and the lesser of the two severe risks for Ukraine and the rest of Europe.

The risks associated with emergency synchronisation, especially for EU neighbouring counties, should be assessed by EU Member States and transmission system operators in light of the critical situation in Ukraine. Security measures could be put in place to minimize the potential risks. The Secretariat will engage to ensure that synchronization, as soon as the circumstances allow, will be matched by a continuation of the reform process in line with Energy Community rules and the conditions requested for certifying Ukraine’s transmission system operator Ukrenergo. We will continue to monitor the security of supply situation in the region.
