NEW YORK - A push is on to harden New York City's electrical infrastructure against future floods.
Superstorm Sandy sent seawater pouring into low-lying power substations and skyscraper basements in late October, causing damage that blacked out half the island for days.
The city's main power utility, public officials and building owners are looking at ways to eliminate vulnerabilities exposed by the surge.
Some skyscraper owners in waterfront areas have already begun moving electrical infrastructure out of basements that flooded during the storm. They say they will house it on higher floors.
Consolidated Edison says it is eyeing possible reconstruction of electrical substations that sit in flood zones. But a complete overhaul could cost as much as $800 million.
