The Power Line That Could Reshape New York’s Grid Is Hitting Snags
During a heat wave on July 3, 2026, New York State’s grid imported enough electricity from Canada to meet about 9% of its total demand that day. Some of that power traveled along a 339-mile underground transmission line stretching from Quebec to Queens—the longest in North America, which opened in May 2026.
The line could supply up to 20% of New York City’s electricity demand, primarily using Quebec’s abundant hydropower. However, challenges have emerged: the line was down for most of this month, and experts worry that drought conditions may impact the hydropower supply feeding it.
Despite these snags, the project could play a pivotal role in shaping the future of the US grid. Read our full story to understand how.

US Threats Against Chinese AI Escalate
In a separate development, the United States has intensified its threats against Chinese AI companies, signaling a new phase in the geopolitical battle over artificial intelligence. These actions, which include potential export controls and sanctions, aim to curb China’s access to advanced AI technologies and hardware. This comes amid growing US concerns about national security and technological leadership, particularly as 2026 sees China accelerate its AI ambitions in areas like autonomous systems and generative AI.
Industry analysts warn that such moves could fragment global AI supply chains and spur China to double down on domestic innovation, potentially reshaping the competitive landscape by 2027.
