Super storm Sandy’s record blackouts and prolonged recovery laid bare the U.S. electrical grid’s vulnerability to wind and flood, renewing calls for utilities to invest billions to toughen their defenses against extreme weather that may become more common.
European countries such as Germany, the Netherlands and the U.K. routinely bury cables that connect homes to power networks, protecting them from wind and ice. U.S. utilities have balked at moving more infrastructure below ground, saying consumers would object to spending as much as $2.1 million a mile, according to one industry estimate, to bury wires for a system that’s not fail-safe.
“There is no system that is bulletproof, whether you bury it, whether you put it up on poles, some force of nature can get you,” John Miksad, senior vice president for electric operations at New York-based Consolidated Edison (ED), owner of New York’s utility. “As powerful as we like to think we are, human designs do have their limitations.”
So the question is, can we afford to not only transition to renewables (requiring greater transmission capacity) but prepare for climate change as well?
