ABB Digitalizes Critical Substation in New York City

2017-03-22 - T&D World article - March 21, 2017
ABB has completed a major upgrade of a key substation in New York City, where several conventional pieces of power equipment have been replaced with digitally-enabled technology, in collaboration with leading energy utility Con Edison. The bulk power substation, among the largest of its kind in the US, supplies electricity to hundreds of thousands of customers in lower Manhattan.

The area suffered significant flood damage from the saltwater storm surge of Hurricane Sandy in 2012, resulting in widespread power outages. Con Edison has since invested heavily to safeguard its power infrastructure, including the protection of substations by reinforcing perimeter walls, gates and floodwalls.

A new elevated design with a modular 420 kV Plug and Switch System (PASS) hybrid switchgear is installed more than 35 feet (10 meters) above the original substation level, to further help avoid the normal path of super storms. The innovative PASS enables a 50 percent space saving and incorporatesĀ a special rotating bushings feature that enables easy transportation and fast onsite installation. These storm protection measures and grid resiliency features are expected to improve power reliability and mitigate outages. As part of the latest digital upgrade by ABB, some 80 percent of the copper control cabling has been rendered obsolete and has been replaced by a few fiber optic cables.
