SatCon Technology Corporation(R) (Nasdaq NM: SATC), a manufacturer of electronic power control systems, today announced that its fuel cell Power Conditioning Unit (PCU) will be used as part of a 250-kilowatt Direct FuelCell(R) (DFC(R)) power plant to be installed by FuelCell Energy, Inc. (Nasdaq NM: FCEL) as part of a temporary distributed power generation micro-grid for the Democratic National Convention to be held at the Fleet Center in Boston on July 26-29, 2004.

According to a July 8th FuelCell Energy release; "The Company's DFC300A power plant will operate on natural gas supplied by Keyspan Energy and will be combined with generators to provide power for the Fleet Center and media stations. FuelCell Energy's DFC power plant, which generates electricity electrochemically and without combustion, will produce 99.9 percent less harmful air pollution and 59 percent less carbon dioxide than traditional combustion-based fossil fuel power plants, and will use half as much fuel per kilowatt hour of electricity than conventional power plants.... The use of the fuel cell power plant not only contributes to the Democratic National Convention Committee's goal of promoting the use of clean and efficient energy generation, but will also demonstrate the operation of ultra-clean technology applicable for electricity solutions around the world."

"Fuel Cells are a power source for an alternative energy power distribution system that can supplement or replace utility grid electricity with higher efficiencies and less harmful pollution," said David Eisenhaure, president and CEO of SatCon Technology. "We have been supplying FuelCell Energy with PCU's for some time and are pleased to see them used in such a high profile application. Our PCU's are designed for use with alternative energy power systems to generate electrical power in office buildings, small factories, hotels and similar facilities. These systems need high-power, high-reliability electronics and controls to convert their output to useable AC power that can then be delivered to the individual user or application."
