District Energy (Heating and Cooling)

In Philadelphia, Veolia Energy's district energy network serves more than 300 customers in the central business district from three steam production facilities and one chilled water facility.

At the 104th annual IDEA conference, in June 2013, city officials from Philadelphia and Boston advocated the value of district energy infrastructure in their cities for a clean energy future (click here for video highlights).

Veolia Energy Philadelphia is regulated by the Pennsylvania Public Utility Commission.

"Green Steam" Avoids Carbon Emissions Equivalent to the Removal of 70,000 Cars

Grays Ferry is one of Veolia Energy's three Philadelphia steam production facilities. Grays Ferry is a 163-megawatt cogeneration facility with a combustion turbine and an extraction/condensing steam turbine. Grays Ferry has a Heat Recovery Steam Generator with duct firing capability and steam capacity of 711 Mlbs per hour, and a 735 Mlbs per hour high-pressure superheat boiler.

Since the 2012 completion of a $60 million investment to upgrade the natural gas infrastructure and to install two rapid-response boilers, Veolia Energy has increased its production of efficient, cogenerated steam ("green steam").

By producing steam and electricity simultaneously, Veolia Energy avoids the emission of approximately 430,000 metric tons of carbon dioxide annually. These avoided emissions are the equivalent of removing 70,000 automobiles from the streets each year.
