The new 500MW HVDC converter station will help the 330kV Lithuanian grid to connect with the 400kV Polish grid.

The power and automation technology group said the development will result in integrating the electricity networks of the Baltic states with the continental European power grid.

In addition to designing and engineering, the company will supply and install the converter station including equipment such as power transformers and thyristor valves.

Schedule to be operational in 2015, the HVDC convertor station will be built near the city of Alytus in Lithuania. A 160km-long 400kV AC overhead power line will connect the station with a substation close to the Polish city of Elk.

ABB Power Systems division head Brice Koch commented, "In addition to facilitating energy trading between Poland and Lithuania, this link will strengthen grid stability and security of power supply in the region."

Currently, the Lithuanian electricity system is connected with the Latvian and Estonian grids. The latest link will bolster the NordBalt HVDC connection with Sweden.
