The Šiauliai–Jelgava power line is an electricity link (interconnector) in the Baltic transmission system (synchronous with the IPS/UPS system) between Lithuania and Latvia. The overhead power line is one of seven interconnections between the two countries and one of the four 330 kV power transmission lines between Lithuania and Latvia.
In 1956, the Lithuanian national electricity grid was established with a link between the Petrašiūnai Power Plant in Kaunas and the Rekyva Power Plant in Šiauliai. Šiauliai (Lithuania) and Jelgava (Latvia) were connected in 1962 creating the first ever transmission link between the two neighbouring countries. It was also the first ever 330 kV power line in Lithuania.[1]
In 1997, a long link with a voltage of 330 kV to the Lithuanian city Telšiai was added to the Šiauliai–Jelgava power line.
