Romania: Transelectrica completed an investment of 18 million euros in the energy infrastructure in Dobrogea

Supported byClarion Energy banner

Transelectrica has completed an investment of around 92 million RON (17.5 million euros) for the consolidation of energy security in the Dobrogea region, the development of the electric transmission network and the national energy system, by building two new 400 kV double-circuit connections, with a total length of 55 kilometers, in the Medgidia Sud 400 kV Electric Substation.

This work made it possible to put into operation four 400 kV overhead power lines, respectively: LEA 400 kV interconnection Medgidia South – Varna (Bulgaria), LEA 400 kV interconnection Medgidia South – Dobrudja (Bulgaria), LEA 400 kV Medgidia South – Stupina and LEA 400 kV Medgidia Sud – Rahman, thus transforming the Medgidia Sud Station into one of interconnection with the Bulgarian electricity system.

The execution works were carried out by the Electromontaj (association leader), ELM Electromontaj Cluj and EMFOR Montaj as subcontractors, and the implementation of the project in the computer systems was carried out with the support of the specialists Teletrans SA, the subsidiary of Transelectrica, which ensured the modelling and integration of the new lines in the EMS – SCADA system, as well as communications and data exchanges with the Bulgarian Transport and System Operator.

Thus, a significant benefit of this work is the reduction of active power losses on 400 kV overhead power lines by approximately 10 MW, under conditions of high electricity production in wind power plants.

At the same time, it will increase the cross-border capacity on the border with Bulgaria for export, with values between 200 MW and 300 MW, and for import by approximately 100 MW.
