"The first tests show that the line is ready to start operations by the end of the year," Karolis Sankovski, director of the Lithuanian power transmission company's Strategic Infrastructure Department, said in a press release.
Electricity flowed via the transmission line for the first time on Thursday. The HVDC back-to-back converter station will be tested next, followed by the testing of the whole interconnection, the transmission system operator said.
The 163-kilometer, 400-kilovolt interconnection runs between Alytus, in southern Lithuania, and Elk, in northwestern Poland.
LitPol Link, worth around 370 million euros, is the first electricity link between the technologically different grids of Lithuania and Western Europe.
