Fig. 1. ABB’s latest high voltage direct current (HVDC) project is based in Lithuania.
BB has won an order worth US$110 million (€85 million) from Litgrid, Lithuania’s state- owned electricity transmission system operator, to supply and
install a high-voltage direct current (HVDC) converter station in the country. Te 500MW back-to-back HVDC converter station will help connect the 330kV Lithuanian grid to the 400kV Polish grid, thereby integrating the electricity networks of the Baltic states with the continental European power grid and contributing to the development of an EU electricity market. At present, the Lithuanian electricity system is connected only with the grids of Latvia, Estonia and the countries to the east. Te new link will also bolster the NordBalt HVDC connection with Sweden, which is currently under construction by ABB.
“In addition to facilitating energy trading
between Poland and Lithuania, this link will strengthen grid stability and security of power supply in the region,” said Brice Koch, head of ABB’s power systems division. “Our leading global track record in HVDC technology was pivotal in winning this order.” ABB will design, engineer, supply and install
the converter station including high-voltage equipment such as power transformers and thyristor valves. Te station will be built near the city of Alytus and is expected to be operational in 2015. A 160km-long 400kV AC overhead line will link the HVDC station in Alytus with a substation close to the city of Elk in Poland. ABB pioneered HVDC technology almost 60
years ago and has now completed more than 90 HVDC projects around the world with a total transmission capacity of more than 95,000MW (Fig. 1).
