The construction works of the Ostrovu Mare – RET (new OPL) 220 double-circuit LEA 220 double-circuit Ostrovu Mare – RET (new line), which will contribute to the discharge of energy produced in the Iron Gates 2 hydropower plant, are at an advanced stage of execution, Transelectrica announces. The line is about 31 kilometres long, has 105 poles and crosses the territory of 5 administrative territorial units in Mehedinți County.

This week took place the investment status control, which was attended by Ștefăniță Munteanu, Chairman of the Transelectrica Board of Directors, and Florin Tătaru, member of the Board of Directors, together with the Director of the Investment Department, Dorinel Vladu, and representatives of the contractor, Electromontaj SA and ELM Electromontaj Cluj SA.

The new 220 kV line will connect the Cetate Station with the 82nd station of Romania’s Electricity Transmission Grid, the Ostrov Station, an investment which is in the public procurement phase for the execution contract. The construction of the new Ostrovu Mare – RET line and the Ostrov station are mainly aimed at increasing the discharge capacity into the National Electricity Grid of the electricity produced in the Iron Gates 2 Hydropower Plant.

The electricity transmission grid managed by the national electricity transmission company Transelectrica SA currently has approximately 9,140 kilometres of 400 kV, 220 kV and 110 kV overhead lines and 81 transformer stations. Over the last six years, the National Transmission and System Operator has built more than 400 kilometres of new 400 kV overhead power lines, and 740 kilometres of high-voltage overhead power lines are under construction until 2030 with a total value of more than 380 million euros.
