Cable issues force a second shutdown at new Hydro-Quebec line supplying New York City electricity

A $6 billion hydroelectric power line that can supply up to 20% of New York City’s electricity has been shut down for the second time this month because of a cable issue, the electric company Hydro-Québec said on Monday.

“Teams working around the clock have identified a cable issue at a location on the US portion of the transmission line,” said Hydro-Québec, which developed the 1,250-megawatt transmission line with Blackstone Inc.

The current cable issue with the power line Champlain Hudson Power Express, which operated during New York City’s recent heat wave, is unrelated to a shutdown that happened on July 1, Hydro-Quebec said.

This is a developing story.
