SatCon Streamlines Operations to Focus Investment Spending on Rapidly Growing Renewable Energy Business

   Record Backlog Exceeds $33 Million

   SatCon Technology Corporation(R) (Nasdaq NM: SATC), a developer
and manufacturer of power electronics and motors for the alternative
energy markets, today announced that it intends to close its
manufacturing facility in Worcester, Massachusetts prior to December
31, 2006, and is streamlining operations to focus spending on the
rapidly growing renewable energy business.
   Orders on hand are at an all-time high of over $33 million,
including more than $16 million from Stationary Power Systems,
SatCon's subsidiary focused on renewable energy products. While total
orders on hand are up over 50 percent compared with this same time a
year ago, the orders on hand for Stationary Power Systems are up
approximately 165 percent, compared with $6 million a year ago, and is
indicative of the success the Company is having in our renewable
energy product lines.
   In order to ensure that the Company will be able to respond
effectively to these rapidly emerging market opportunities, steps are
being taken to curtail activities in non-strategic product lines and
direct working capital towards growth markets like photovoltaic
inverters.
   "Our record level of orders on hand gives me confidence that we
are on track to transform this company into a high growth renewable
energy company. We believe that the steps we are taking to consolidate
facilities and align our organization with our product and market
initiatives will ultimately drive the business towards
sustainability," said David Eisenhaure, Chairman and Chief Executive
Officer. "We are taking the opportunity to do more work in fewer
square feet of manufacturing space by reducing our facilities' space
by approximately one third and yet continue to grow our revenues in
our strategic product areas. The combination of reducing costs,
identifying non-strategic initiatives and focusing on high growth
market opportunities is expected to drive significant productivity
gains and result in improved financial performance."
