Image description

The image shows the map of Romania with the very high voltage electrical network, respectively four hundred kilovolts, distributed by the Transelectrica company.

The map of the country is marked embossed, and the border is outlined with in bold.

The overhead power lines are rendered by thick and blank lines, joined together by blank circles, these representing the transformation stations, also called electric substations, of the high voltage lines.

The overhead power lines highlighted by blank dashed lines refer to those proposed as projects.

Similar to them are the proposed transformer stations, which are rendered by blank squares.

The electric substation is part of the chain of electrical distribution networks, with the role of reducing the high voltage from the power lines, so that the modified voltage is compatible for public consumption.

The distribution of the electricity network is zonal or within the big cities, municipalities of the country.

The most frequent electric substations are located in the southern and southeastern part of Romania, respectively Bucharest in the south central area, and the surrounding region, then Dobrogea with Tulcea, Constanța and Cernavoda, in the southeast area.

General information

From generator to consumer, the electric current passes through several phases. Power generation is carried out in power plants of different types. After generation, the current is converted, amplified, or reduced, depending on the destination, using the transformer stations. From transformer stations to consumers, electricity is transported using electrical cables.

The distribution network comprises all substations and electrical cables by which electricity is transported from the generator to the consumer. Like roads, the electricity distribution network has a map on which are listed all the power transformer stations and all the electrical cables, as well as the localities they interconnect. Just as a road connects two or more localities, so do the electrical cables, which, together with the transformer stations, interconnect several towns and villages. The national electricity grid also has links even with the neighboring states of Romania.

Major electricity production is concentrated in the southern part of our country because there is the Danube with the most important hydropower plants in the country, namely Iron Gates One and Two. Also in the South, we also have the most extensive solar and wind parks.

In the center of Transylvania, the most important node, that is the point of interconnection between counties, is the electric transformation station at Campia Turzii. This node connects the counties of Cluj, Alba and Mureş.

In Bihor County, there is the Oradea Sud station which electrically interconnects the West, the North and the South of Romania.

The national electricity grid consists of eighty-one power stations and over eight thousand kilometres of overhead cables.
