Long, buried transmission lines can import large amounts of clean hydroelectricity from neighboring jurisdictions directly into dense urban grids, supplying a substantial fraction of city demand while avoiding visible overhead infrastructure. Building them requires specialized cable imports, converter stations, and thousands of localized easements and permits, creating new governance and supply‑chain dependencies.
— If replicated, this model reshapes urban decarbonization strategy, shifting emphasis from local generation and rooftop solar toward cross‑border transmission and associated permitting, supply‑chain, and sovereignty questions.
