Romanian transmission system operator Transelectrica expects construction of the 400 kV Suceava-Bălți power interconnector with Moldova to start in early 2027, as permitting for the Romanian section advances. The line will extend about 93.3 kilometres through Suceava and Botoșani counties. It is intended to strengthen Moldova’s connection to the continental European electricity system and reinforce Romania’s transmission network.
The investment is estimated at approximately €25 million excluding VAT, and construction is expected to take around 36 months. Transelectrica has selected the contractors, awarding a design-and-construction contract in March 2025 to a consortium led by Electromontaj and including ELM Electromontaj Cluj. Most preparatory work is complete, with final construction permits and outstanding administrative procedures remaining.
Cross-border and transmission network role
The Suceava-Bălți project has a broader strategic role than a single border connection. It will support Moldova’s deeper integration with the European ENTSO-E system and contribute to completing Romania’s national 400 kV transmission ring. The line is expected to improve electricity flows through northern Romania and expand the physical infrastructure available for cross-border electricity exchange with Moldova.
The investment comes as transmission infrastructure grows in importance for security of supply and renewable integration across eastern and southeastern Europe. For Romania, the line would strengthen an increasingly important eastern border. For Moldova, it would add another physical connection to the European electricity system and reduce the strategic significance of more vulnerable supply routes.
