A 339-mile underground power line, designed to transport hydropower from Quebec to Queens, is currently facing operational hurdles. The infrastructure, which officially launched in May, serves as the longest underground transmission line in North America and has the capacity to supply up to 20% of New York City’s electricity needs.

The project, intended to bolster the state's energy grid, has been inactive for much of July. The disruption comes shortly after the line demonstrated its potential during a July 3 heat wave, when it contributed approximately 9% of the state's total electricity demand. Experts are now evaluating the long-term viability of the project, particularly regarding how regional drought conditions might impact the availability of the hydropower supply.
