Description
Hitachi Energy (then ABB) was awarded a turnkey contract by Lithuanian TSO Litgrid, together with Svenska kraftnät, in December 2010 to deliver the HVDC cable system for the 700 MW, ±300 kV NordBalt interconnector between Lithuania and Sweden. The scope covered engineering and design of the HVDC Light cable system, manufacture of two 300 kV XLPE submarine cables of about 400 km each (around 800 km of subsea cable in total), and the associated underground land cables on both shores (approximately 106 km in total). Hitachi Energy also supplied and installed the submarine and land cables, including offshore laying, landfall works, jointing and commissioning, in parallel with its converter station deliveries. The specific cable contract was valued at about €270 million and enabled the first direct HVDC power exchange between the Nordic and Baltic electricity markets.
