Plug Power launches new fuel cell product providing heat and electricity

LATHAM, N.Y., July 26, 2002 — Plug Power Inc. introduced the GenSys™5C, the company’s new Combined Heat and Power (CHP) fuel cell system, at the Town Hall in Babylon, N. Y.

The Plug Power GenSys™5C unit is installed and operating at the Babylon Town Hall where it provides supplemental heat and electricity to the facility. “LIPA is proud to be a pioneer in the field of fuel cell technology,” said LIPA Chairman Richard M. Kessel.

“LIPA believes that fuel cells hold the key to achieving true distributed generation that makes economic and environmental sense. Installation of this unit will help us better understand the issues associated with the integration of fuel cells at customers’ facilities where heat produced by the units can also be used.”

The GenSys™5C, which is based on Plug Power’s proprietary technology, captures the heat generated during the production of electricity and makes it available for integration into a heating or hot water system. The system is capable of generating 5kW of electricity and 9kW of heat and is available immediately, with an expected order-to-delivery lead-time of eight to ten weeks.

“Our extensive field experience and market engagement activities over the past two years have allowed us to incorporate direct customer feedback into the GenSys™5C product,” said Mark Sperry, Plug Power Vice President and Chief Marketing Officer. “The increased efficiency achieved by capturing and utilizing the heat generated within the system enables a lower total cost of energy, which is critical to our customers.”

Plug Power has been awarded multiple patents pertaining to combined heat and power fuel cell products. The patents cover the use and control of an integrated fuel cell system for providing electricity and domestic hot water to a building. The company’s current patent portfolio includes 53 issued patents and 130 patent applications pending worldwide

GenSys™5C was evaluated and certified by CSA International (CSA) and is certified as compliant with the American National Standards Institute (ANSI) standard for fuel cell power plants. The power conversion system was evaluated by the Underwriters Laboratories Inc. (UL) and is listed as compliant with the standard for Inverters, Converters and Controllers for use in independent power systems. GenSys™5C conforms to the Federal Communications Commission (FCC) standards for Electromagnetic Compliance (EMC).

Plug Power designs, develops and manufacturers on-site electric power generation systems utilizing Proton Exchange Membrane fuel cells for stationary applications. Plug Power’s fuel cell systems are expected to be sold globally through a joint venture with General Electric and through DTE Energy Technologies in a four-state territory, which includes Michigan, Illinois, Ohio and Indiana. The company’s headquarters are located in Latham, N.Y., with offices in Washington, D.C. and The Netherlands.
