Litgrid

To strengthen the electricity substation of Vilnius city and ensure reliable electricity transmission to the country's capital by reconstructing the 330 kV electricity transmission overhead line Lithuanian power plant - Vilnius from single-circuit to double-circuit.

Significance of the project

By implementing the strategic goals of the state and reorienting the Lithuanian electricity system to work in synchronous mode with the networks of continental Europe, reliable electricity transmission must be ensured and the security of electricity supply must be increased.

Synchronisation with the Central European Synchronous Area (CESA)is the last step towards Lithuania’s energy independence. Currently, our electricity system is still dependent on frequency control in Russia, but already in 2025, it will operate in one synchronous area together with the systems of other European countries.

Currently, electricity supply to consumers in the Vilnius region is ensured from two 330 kV transformer substations - Neris and Vilnius. In order to ensure a reliable supply of electricity to both existing and new consumers in the Vilnius region, after synchronisation with the continental European grid, the 330 kV overhead line from the Lithuanian power plant to Vilnius was renewed and strengthened.

Reconstruction of the electricity transmission line from the Lithuanian power plant to Vilnius was one of the first works to strengthen the Vilnius node, which is necessary to ensure a reliable electricity supply after the disconnection of the lines connecting the Lithuanian and Belarusian electricity systems.

General project information

During the reconstruction of the power transmission overhead line Lithuanian power plant – Vilnius, all supports of the line were replaced, and a double-circuit power transmission line (instead of the former single-circuit) was built on the newly installed supports. The works were carried out in the existing engineering corridor, the former protection zones have been retained. The overhead line passes through the municipalities of Elektrėnai, Trakai district and Vilnius.
