SatCon Wins $1.1 Million Navy Contract for Integrated Motor Propulsor and Controller

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 has been awarded a
Phase II SBIR 'cost-plus' contract for an integrated motor propulsor
(IMP) with the Office of Naval Research (ONR). The total value of the
contract is $1.1 Million and will be funded over the term of the
project.
   SatCon will design, fabricate, test, and deliver a complete
integrated motor propulsor (IMP) system including motor, controller,
and podded propulsor. An IMP enables propulsion for marine vehicles
without any mechanical shaft couplings to a power generation source.
Final unit delivery and testing at a Navy facility is scheduled for
early 2008.
   "SatCon is pleased to continue our strong relationship with the US
Navy," stated SatCon's President and Chief Operating Officer, Millard
Firebaugh. "Not only does this contract support our stated strategic
initiative to expand our Navy business, but contributes to other
product initiatives within SatCon, such as advanced micro-hydro power
generation using rim-driven motors. The technology developed as a
result of this effort will benefit our hybrid electric vehicle and
aerospace offerings for higher power density, higher efficiency
electric drive solutions."
   This propulsor technology expands on machinery research and
development conducted at SatCon on low weight permanent-magnet
rim-motors for naval underwater propulsor applications, and high power
density liquid cooled machinery for hybrid electric vehicle
applications. The goal is to advance the state of the art to a power
density exceeding 0.6 HP/lb for a complete 50 HP IMP system.
   This effort supports the Navy's Future Naval Capabilities thrust
towards all electric drives and unmanned systems. Podded propulsion
systems promise to reduce overall ship system weight, reduce in-hull
space claims, and improve overall power conversion efficiency.
Furthermore, they enable higher power unmanned underwater vehicle
(UUV) applications to increase range and endurance for improved
mission effectiveness.
   The award is another example of SatCon's expertise in electric
power conversion systems for vehicle applications. Our permanent
magnet machine technologies result in high-efficiency, low weight
designs that have demonstrated steady improvement with each design
generation. Our power electronics expertise in component packaging,
system architecture, and software controls enables us to develop
efficient and compact solutions for challenging applications within
constrained space and environmental requirements.
