Romanian transmission system operator Transelectrica expects work on the 400 kV Suceava-Bălți connection with Moldova to begin in early 2027, as permits for the Romanian section advance. The electricity interconnector will reinforce Moldova’s link with the continental European power system and strengthen Romania’s transmission network.
The Romanian section will extend about 93.3 kilometres through Suceava and Botoșani counties. The investment is estimated at approximately €25 million excluding VAT, and construction is expected to take around 36 months.
Transelectrica has selected the contractors for the project. In March 2025, it awarded a design-and-construction contract to a consortium led by Electromontaj and including ELM Electromontaj Cluj.
Permits and construction preparations
Much of the preparatory work has been completed, and attention is now turning to the final construction permits and remaining administrative procedures.
Cross-border and transmission benefits
The project’s strategic role extends beyond a single border connection. It is intended to 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 add physical infrastructure for cross-border power exchange with Moldova. The investment comes as transmission infrastructure gains importance for security of supply and renewable energy integration across eastern and southeastern Europe.
For Romania, the line would strengthen an increasingly important eastern border. For Moldova, it would provide another physical connection to the European electricity system and reduce the strategic importance of more vulnerable supply routes.
