The Hydro-Quebec electricity transmission system is an international electric power transmission network centered in Quebec, Canada. It pioneered the use of very high voltage 735 kilovolt alternating current power lines, which link the population centers of Montreal and Quebec City to distant hydroelectric generating stations such as the Daniel-Johnson Dam, the James Bay Project in northwestern Quebec, and the Churchill Falls Generating Station in Labrador.

Why did the Quebec power grid fail in the 1998 ice storm if its towers were built for heavy ice?
The storm deposited up to 70 millimetres of ice, far beyond even the raised design standard.
The towers and lines were built to a standard of ice tolerance more than three times higher than the Canadian standard of 13 millimetres. The ice storm of the late 1990s was heavier still, depositing up to 70 millimetres of ice, which exceeded what the system was designed to carry.
