According to Hydro-Quebec, the outages on Thursday occurred when protective devices tripped on two 735-kV transmission lines carrying power from James Bay to southern Quebec.

“Power was gradually restored from the Hydro-Quebec grid in the southern part of the province,” it noted in a statement released Thursday night.

“But the transmission lines affected are still unavailable. They are being inspected, which is more difficult in the dark. In addition to the ongoing ground patrol, there will be a helicopter patrol at daybreak.”
