“NordBalt” - the submarine interconnection between Lithuania and Sweden, which has been in operation since 2015, ensures a diversity of electricity sources, which in the first year of operation has determined up to 30% reduced electricity prices.
The strategic electricity project was implemented by Litgrid, the Lithuanian electricity transmission system operator, and Svenska Kraftnät, the Swedish electricity transmission system operator.

The aim of the “NordBalt” project is to establish an interconnection between Lithuania and Sweden. The connection is about 450 km long and 700 MW. This connection consists of high-voltage direct current submarine and underground cables and converter stations in Lithuania and Sweden. An integral part of this strategic project is the reconstruction of Klaipėda Transformer Substation, which was completed in 2014, and the 330 kV Klaipėda-Telšiai power transmission line, which was commissioned in mid-October 2014.
