ABB will deliver a high-voltage direct current (HVDC) converter station that will add 1,250 MW of transmission capacity between the provinces by March 2009. The new converter station in southern Quebec will create a new interconnection between the 315 kV grid in Quebec and the 230 kV grid in Ontario. ABB’s scope of supply includes design and manufacture of equipment, installation, commissioning and civil works.

In addition to improving grid reliability in both provinces, Ontario will benefit by having substantially more access to hydroelectric power from Quebec.
