Steps in this direction include an automation system that can divide two of the region’s distribution grids into a total of four sub grids in just fractions of a second, thus preventing a disturbance from spreading throughout the entire grid. This allows the power supply in the undamaged sections to remain in service so that an outage affects fewer people. The area where the power supply has now been designed to better withstand storms includes the Financial District.
When hurricanes make land, they often cause flooding, sometimes resulting in power outages. Such events can spread throughout the grid in a matter of seconds and can also knock out the power in unflooded regions. After Hurricane Sandy swept through the region in 2012, more than 800,000 New Yorkers were left without electricity for days. Experts predict that the number of violent storms will continue to rise in the future, which is why Con Edison decided to invest in measures to enhance the resilience of its infrastructure.
