Levis De-Icer

HVDC transmission linesHydro-QuébecVague or ambiguous time from June 2023

The Levis De-Icer is a High voltage direct current (HVDC) system, aimed at de-icing multiple AC power lines in Quebec, Canada. It is the only HVDC system not used for power transmission. In the winter of 1998, Québec's power lines were toppled by icing, sometimes up to 75 mm. To prevent such a damage, a de-icing system was developed.The Levis De-Icer can use a maximum power of 250 MW; its operation voltage is ±17.4 kV. It can be used on multiple 735 kV AC power lines. When there is no icing, the Lévis De-Icer installed at Hydro-Québec's Lévis substation operates as static VAR compensator improving the stability of the AC lines.
