Eastern and western system parts connected with one 330 kV double-link line Kruonis HPSPP-Lietuvos PP. </p><p>• In&nbsp;the far future it is necessary to improve security of supply for Vilnius region – should be build third 330 kV substation near Vilnius, to connect Vilnius and Neris 330 kV substations.
