Troll A 1&2 entered commercial operation on 1 October 2005, when the 88 MW HVDC Light power-from-shore system began delivering electricity from the onshore rectifier station at Kollsnes to the offshore Troll A platform via approximately 70 km of subsea cable at plus or minus 60 kV. This was the world first HVDC Light installation to an offshore platform, replacing gas turbine-driven compressors with electrically driven units. Testing had been completed in February 2005, with the two compressor units brought into operation in early October. The system was delivered by ABB (now Hitachi Energy).
