Power and automation technology group ABB has secured an order worth $50m from Hydro-Quebec to upgrade a ultra-high voltage transmission system in Canada.

The transmission system will help transport clean hydroelectric power from the north to south of Quebec.

The two Static Var Compensators in the Nemiscau substation, about 1,000km north of Montreal, provide fast-acting reactive power compensation in the 735kV electricity network.

ABB head of power systems division Peter Leupp said the upgrades will provide significant life extension of the SVCs and reduce electrical losses substantially in addition to enhancing the reliability of the existing grid.

The upgrades are scheduled to be complete by 2014.
