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

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

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-Québec said.
