TEC Infrastructure ensured a smooth technical supervision of general reconstruction works that included the works of replacement of all the supports of this line: a total of 184 supports were replaced into new metal ones. During the reconstruction, the structures of the supports were dismantled, new foundations were installed, metal galvanised supports were installed, the cables were laid and the lightning protection cable with a fibre optic cable was installed.
The works started in September 2020 and today we are pleased to see the results. The 61 km long power transmission line stretches over 4 municipalities of Lithuania: Elektrėnai (16.2 km), Kaišiadorys District (6 km), Prienai (16 km) and Alytus District (22.4 km). This project was exceptional for the TEC Group as our involvement had to be quick and we had to join the project when the construction was already in progress. Another challenge of this project was the weather. When laying power transmission line, some sections were impassable due to wet meadows and marshes, therefore, we had to wait for a colder season to ensure smoother transportation of materials.
It is crucial to ensure a smooth and continuous transmission of energy to the consumers, as storing of electricity in large quantities is impossible and it must be produced and supplied in real time. The reconstruction of this power transmission line will significantly contribute to the reliability of the power transmission network and will allow to ensure a more stable electricity supply for the consumers of this region and the entire Lithuania.
According to Miron Čebatul, the Technical Supervision Manager of general construction works at TEC Infrastructure, during the construction works, it was necessary to control that the progress and the results of the construction of the building would be in line with the construction design, and the fertile upper layer of soil would be excavated and stored in the course of construction, and returned to the original site after the completion of works, in order to restore the former condition of the territory. In order not to disturb the life of birds in ornithological reserve areas, reconstruction works were not carried out in these sections from April 1 to August 1. In the territories where the power transmission line is close to the residential areas, fixing of cables as high as possible was ensured according to the technical possibilities.
