The PCUs 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 power to useable AC power that can then be delivered to the individual user or application. SatCon's electronics enable these alternative energy systems to be utility grid compatible in order to be tied to the existing electric utility grid. Alternative energy systems can alleviate congestion on highly loaded utility distribution networks and offer an alternative to power line extensions in remote areas.

"Sales for our PCUs for alternative energy applications are strong and growing," said Millard Firebaugh, President and COO of SatCon Technology Corporation. "SatCon has sold over 100 units at the 30 to 225 kilowatts power levels and 40 units at power levels above 300 kilowatts since we entered the PCU market for alternative energy applications including fuel cells, solar-photovoltaics and advanced battery applications. The world-wide market for higher power PCUs, by various analysts' estimates will grow from about $95 million per year to over $575 million per year over the next six years. Good news for SatCon."
