Transelectrica has completed the most challenging 400 kV overhead power line project in the last 30 years

Transelectrica reports the successful completion of a significant project within the last 30 years. The construction project of the 400 kV Portile de Fier – (Anina) – Reșița Overhead Power Line (LEA, OPL) has been finished, with the line passing the energization test on February 29, 2024.

The investment project, valued at 150 million lei, was carried out by Asocierea ELECTROMONTAJ S.A. BUCURESTI – ROMELECTRO S.A., with subcontractors EMFOR MONTAJ SA, SC ELECTROMONTAJ SA Sibiu, and SC ELECTROMONTAJ SA Cluj. The line’s design was undertaken by the Bucharest Institute of Energy Studies and Design.

The energization of the newly constructed line signifies the conclusion of the execution works, validating the technical functionality of the electrical installation. Spanning a mostly mountainous area with rugged and challenging terrain, the Overhead Power Line 400 kV Portile de Fier – (Anina) – Reșita stands out as the most intricate and demanding line project undertaken in Romania over the past three decades. The technical complexities and hurdles faced by the project teams, both from the builders and the Company, showcase the remarkable efforts of the specialists involved in completing this line.

Operationally, the 400 kV Portile de Fier Overhead Power Line – (Anina) – Reșita will commence with the completion of the construction works of the 400 kV Reșita station, expected in the second half of this year. Simultaneously, the new 400 kV Reșita station will facilitate the operation of the 400 kV Reșita – Pancevo Overhead Electric Line.

With a total length of 117 kilometers, the new 400 kV Portile de Fier Overhead Power Line – (Anina) – Reșița comprises two sections: a newly constructed segment with 259 poles (the Portile de Fier – Anina section), spanning 81.1 kilometers, and the modernization of an existing line with 142 poles (Anina – Reșita section), covering 36 kilometers.
