Subway Emergency Power

PCTI Supports Subway Infrastructure Program Post Hurricane Sandy

Hurricane Sandy was the largest Atlantic Hurricane on record, and the second most costly hurricane in US history. In Manhattan, despite covering entrances and vents, erecting flood walls across tracks, and readying pumps, each of the seven subway tunnels leading into lower Manhattan took on water. Following Hurricane Sandy, the South Eastern Pennsylvania Transit Authority (SEPTA) was facing a challenge to improve its aging infrastructure that became increasingly vulnerable to extreme weather.  Power electronics company Power Conversion Technologies, Inc. worked with SEPTA to solve one of those issues, specifically their subway pump room emergency power project.

The Emergency Power Project

The project integrates a series of emergency power systems for pump rooms throughout the subway tunnels in the City of Philadelphia.  The pump room project is part of a larger $86.8 million federal grant to strengthen the transit authority’s infrastructure against storms.

Pumps are active 24/7, pumping out groundwater from the subway tunnels. The pumps are located close to the Schuylkill River which presents a challenge to keep underground tunnels dry.  An integrated emergency power network will help to protect passengers and infrastructure from the risk of flooding that could result from widespread power outages.

Phase 3 of PCTI’s DC/AC Inverters for SEPTA ranging from 50-200KVA

PCTI Provides DC/AC Inverters to Fix Issues

PCTI’s DC/AC inverters ranging from 50KVA to 200KVA will take the power from the subway’s third rail and convert it usable power to support 100 horsepower pumps.

The inverters will supply back-up power, providing resilience to localized or regional power outages, to help keep the 22 pump rooms dry. This project is one of the many to keep SEPTA up and running in the midst of dangerous weather and to keep passengers safe.
