Con Edison: One year after Hurricane Sandy
NEW YORK - - A year after Superstorm Sandy ravaged the New York area, Con Edison has made numerous improvements to its energy-delivery systems as part of a $1 billion plan to fortify critical infrastructure and protect New Yorkers from major storms. Overhead equipment is now tougher and more resilient. Substations have new walls and raised equipment. Gas and steam infrastructure also is protected with water-proofing measures.
“Con Edison’s 14,000 workers have all played a role in developing a fortified energy system,” said Con Edison President Craig Ivey. “Damaging weather is becoming more frequent. When a storm hits the region, we want to restore customers safely and quickly. We are responding to Sandy by building a tougher system.”
