History
The decision to build this powerline was made in 1977 and it went in operation in 1985. The line went out of service after Poland joined thesynchronous grid of Continental Europe

However, there was a plan to re-activate this line after 2010 by constructing a back-to-back conversion station on the Polish end of the line, but this was not implemented.

from the Ukrainian power grid and using the powerline to connect to the Burshtyn TES energy island which operates on the European power grid, to facilitate exports to Poland and Hungary. In 2019 the Ministry of Energy created a consortium, Ukraine Power Bridge Company Limited, to progress the project, but as of 2020 the project was not agreed. In 2022 Ukraine's grid had synchronised with the European grid and restoration work on the line began. As of 2023, it is operational at 400 kV.
