Siemens partners with Con Edison to install storm hardening system in lower Manhattan

  • Distribution feeder automation technology will allow Con Edison to keep power flowing to area of lower Manhattan during flooding
  • First U.S. utility to install this type of power network separation technology

Siemens is partnering with Con Edison, the utility that powers New York City, to install technology that will help keep Con Edison customers in sections of Lower Manhattan in service during severe flooding. With its distribution feeder automation project Con Edison will ensure that unexpected weather events and flooding will no longer impact their entire power system, making them more resilient and prepared for the future.

Con Edison chose Siemens to collaborate on a new automation system to synchronously control underground switches and circuit breakers that will separate two of Con Edison's power distribution networks into four sub-networks.

That will allow the utility to continue delivering power to parts of Lower Manhattan, including Wall Street, in the event of flooding to coastal areas. Con Edison is the first utility in the U.S. to implement this storm-hardening technology.

For Con Edison the cooperation with Siemens is an important part of its program to fortify its energy-delivery systems and protect its customers from severe weather events like Superstorm Sandy and Hurricane Irene.

Siemens developed the distribution feeder automation technology specifically for Con Edison's system out of its Wendell, North Carolina, USA, research and development hub. Siemens' technology will allow the system to issue open and close commands within four milliseconds from Siemens field devices that control the circuit breakers and underground sectionalizing switches that in turn switch the power to the sub-networks. The system will operate across more than 44 primary circuits. This custom automation system is interoperable with Con Edison's control systems and installed primary switchgear.
