Estonia, Tallinn: Estonia’s TSO Elering has successfully completed the reconstruction work on the Viru-Tsirguliina 330 kV overhead transmission line, which constitutes a part of the major project for synchronisation with Continental Europe. This is one of the largest and most important physical infrastructure objects in Estonia required for synchronisation. The connection was energised on 5 November.
Work began in June 2023 and was completed in October 2024, with maintenance and cleaning work partially ongoing. Within the framework of the project, the 244 km line was overhauled, including the replacement of the outdated Soviet-era line cables and towers with modern ones. About 50 hectares of land were reclaimed from the protection zone.
On the Viru-Mustvee line section, 257 towers were erected, while 469 towers were erected on the Mustvee-Tsirguliina section. The main contractors Leonhard Weiss and Enersense performed the construction work.
Hannes Kont, Head of Project Management and Director of the Synchronisation Program of Elering explained that after disconnecting from the Russian electricity system, the Baltic countries must maintain a reinforced north-south electricity connection.
On 8 February, the system operators of the Baltic countries will desynchronise the Estonian, Latvian and Lithuanian electricity systems from the Russian synchronous area. This will be followed by an isolated operation test in the course of which the capacity of the electricity systems of the three Baltic countries will be evaluated. Synchronisation with the Continental European frequency area is planned to take place on 9 February 2025.
