Transelectrica’s 400 kV Portile de Fier – (Anina) – Resita OHL Project Completed
The 400 kV Portile de Fier – (Anina) – Resita overhead power line (OHL), the most challenging project of the last 30 years, has been successfully completed.
The project for the construction of the 400 kV Portile de Fier – (Anina) – Resita Overhead Power Line has been completed and the line successfully passed the energisation test on 29 February 2024. The total value of the investment project is RON 150 million, the works being carried out by the ELECTROMONTAJ S.A. BUCHAREST – ROMELECTRO S.A. Joint Venture, with subcontractors: EMFOR MONTAJ SA, SC ELECTROMONTAJ SA Sibiu and SC ELECTROMONTAJ SA Cluj. The design of the line was carried out by the Bucharest Institute for Studies and Power Engineering.
The energisation of the newly built line marks the end of the execution works by testing the technical functioning of the electrical installation. The Portile de Fier – (Anina) – Resita 400 kV Overhead Power Line is the most technically complex and difficult line project in Romania in the last 30 years, as its route crosses mostly mountainous, rugged, and inaccessible terrain. The technical complexity and the challenges that the project teams, both of the builders and the Company, encountered in the process of executing the works reflect the extraordinary effort of the specialists who contributed to the completion of this line.
The Portile de Fier – (Anina) – Resita 400 kV overhead power line will be operationally commissioned upon completion of the construction of the 400 kV Resita substation, which is expected in the second half of this year. At the same time, the new 400 kV Resita substation will allow the operation of the 400 kV Resita – Pancevo interconnection overhead line.
The new 400 kV Portile de Fier – (Anina) – Resita overhead power line has a total length of 117 kilometres and consists of two sections: a new construction of 259 poles (Portile de Fier – Anina section), with a length of 81.1 kilometres, and the modernisation of an existing line of 142 poles (Anina – Resita section), with a length of 36 kilometres.
