The Transmission System Operators (TSOs) of Continental Europe have agreed to increase the trade capacity with Ukraine and Moldova from 100 MW to 250 MW. Commercial electricity exchanges with the Ukraine/Moldova power system started on 30 June 2022 on the interconnection between Ukraine and Romania, followed by the Ukraine-Slovakia interconnection on 7 July 2022. Electricity trading on the other interconnections (Ukraine-Hungary and Moldova-Romania) is expected to follow later. The possibility of further increasing trade capacity will be assessed in September based on power system stability and security considerations. Ukraine is a net exporter of electricity, with 1.6 TWh of net exports in 2021. Moldova is a net importer of electricity, with 3.4 TWh in 2019.
In March 2022, the electricity grids of Ukraine and Moldova were synchronised with the Continental European Grid. The two countries, which were previously linked with the IPS/UPS electricity system (former USSR system) including the Unified Power System of Russia as well as the national networks of Kazakhstan, Kyrgyzstan, Belarus, Azerbaijan, Tajikistan, Georgia, and Mongolia, disconnected their power systems from the networks of Russia and Belarus in February 2022, following the Russian invasion of Ukraine. Subsequently, Ukrenergo applied for emergency synchronisation with the European power system, which was previously scheduled in 2023.
