The project for the construction of the 400 kV Cernavoda – Stalpu overhead transmission line has successfully overcame its most difficult and challenging technical stage, namely the crossing of the Danube over 2.6 kilometers, of which 1.13 kilometers are above water. The section was completed by Electromontaj.
The section crossing the Danube River was completed in approximately three weeks, including the preparatory phases. Its complexity and uniqueness involved special efforts on the part of the constructors and expert teams of electricity transmission system operator Transelectrica, being the first such large-scale electrical engineering work carried out in the Romanian electricity transmission system in the last 35 years. The double-circuit overhead transmission line is supported on both banks of the Danube by the highest high-voltage poles of the entire national energy infrastructure, measuring the height of 150 meters.
The only work of this type that crosses the Danube was carried out in 1987, being the 400 kV Cernavoda – Gura Ialomitei transmission line.
The 400 kV Cernavoda – Stalpu overhead transmission line project, with a total investment of around 75 million euros, benefits from non- refundable co-financing of 27 million euros through the Connecting Europe Facility (CEF). The project is part of the North-South Interconnection East Electricity Corridor and aims to strengthen the cross-section between the west coast of the Black Sea and the rest of the European system, contributing at the same time to the strengthening of the electricity transmission network in
Romania, to the increase of the interconnection capacity between Romania and Bulgaria and to the integration of the wind energy produced in the Dobrogea area.
