The design and construction works of L301 Tartu-Valmiera 330/110kV overhead line started

During the construction works the old overhead line will be demolished and utilized in full (approximately 85 km). After the demolition of the old line, new foundations will be laid, new poles and wires will be delivered and installed. During the renovation works, more than 300 poles will be demolished and erected. The 110 kV overhead lines running in parallel will be installed on the same poles as the 330 kV line with joint suspension.

 Upon completion of the L301 overhead line project, the security of supply of both the Estonian and Latvian electricity systems will increase significantly and the capacity between Estonia and Latvia will improve.
