Macy?s East Inc. CHP Demonstration(ST8577-1)

Energy Concepts Engineering, P.C.

Background

Macy’s East operates a combined retail and office building in Brooklyn that serves as the host site for this project. This facility, with more than 800 employees occupying more than 1 million square feet, operates year round and requires electric power, heating and air conditioning.

Project Description

The Combined Heat and Power (CHP) system uses modular induction-type engine-driven generators. The CHP system operates in parallel with the local electric utility grid in the electric service territory of Consolidated Edison Company of New York, Inc. (Con Edison). The system recovers heat to drive an absorption chiller. The project has installed and demonstrated the efficiency of a CHP system, with several engine generators totaling 875 kW. The CHP plant provides electricity to several separate electric services (separate meters); it was determined that it would not be cost-effective to re-wire the site to aggregate electric services under a single meter.

Benefits

The recovered heat is captured in the form of hot water for preheating condensate return water and boiler makeup water, and in the form of steam for space heating as a supplement to the existing boilers and for operating absorbers for chilled water cooling. Technology transfer and publicity has emphasized wide dissemination of the project results. This project is forecast to provide peak load reduction of approximately 875 kW, and result in over $400,000 in annual net annual energy savings for the host site facility. It is forecast that approximately 80% of the engine’s input fuel will be used through electric power and heat.

Project Results

The CHP system began operation in late 2008; performance data is publicly-available at http://chp.nyserda.org
