1.2 Megawatt Power Plant is the Largest Distributed Generation Power Plant Certified for the California Market

FuelCell Energy, Inc. (Nasdaq:FCEL), a leading manufacturer of high-efficiency, ultra-clean power plants for commercial, industrial and utility customers, today announced that its DFC1500MA(tm) has received three certifications that confirm the 1.2 MW power plant meets California's emission regulations and complies with both requirements for connecting to power grids and national product safety standards.

FuelCell Energy's DFC1500MA(tm) system met the stringent air quality rules set by the California Air Resources Board (CARB); was certified by the Rule 21 Working Group to technical requirements for interconnecting with California's power grid; and was approved by CSA International for its adherence to the American National Standard for Stationary Fuel Cell Power Systems operating and safety standards.

These certifications have the effect of simplifying or shortening the approval process for installing on-site forms of power generation like Direct FuelCell(r) (DFC(r)) power plants. Their comprehensive pre-qualification tests reduce or eliminate the need to obtain certain permits; affirms the power plant's ultra-clean emission profile; and confirms its ability to connect safely with the existing power infrastructure.

"Our customers can be assured that our DFC fuel cells operate at the highest standards for air quality, interconnection and safety," said William Karambelas, FuelCell Energy Vice President of Business Development. "Local authorities are also assured of compliance with applicable standards which can reduce the time required in the approval and permitting processes."

 * CARB 2007 measures a product's adherence to California's
   toughest-in-the-nation air quality rules.  With the certification,
   the DFC1500MA system may be installed in California Air Quality
   Management Districts without obtaining an air permit (please see
   http://www.arb.ca.gov) and the power plant is eligible for
   preferential rate treatment such as elimination of "exit fees" and
   "standby charges" for electric generation at customer sites.

 * The Rule 21 Working Group develops comprehensive interconnection,
   operation and metering requirements for customer-sited generation
   in California. Its guidelines have been rolled into the
   interconnection requirements of utilities across the U.S., so the
   DFC1500 MA certification is beneficial across the country. The
   DFC1500MA system is the largest distributed generation power plant
   certified to Rule 21 and it is the fourth FuelCell Energy power
   plant to gain the accreditation.

 * CSA International is accredited by the U.S. Occupational Safety and
   Health Administration (OSHA) to evaluate stationary fuel cell power
   systems against ANSI/CSA America FC1-2004 (the established American
   standard for stationary fuel cell power systems).  Certification of
   the DFC1500MA system assures local authorities that the power plant
   meets all design, construction, operational, quality and safety
   requirements.
 

FuelCell Energy's DFC power plants may be situated close to where electricity is needed because they dramatically reduce the noise, NOX, SOX and particulate matter associated with traditional means of generation such as turbines or combustion engines. In addition to producing ultra-clean electricity 24/7, DFC power plants can run on a variety of fuels, including renewable biofuels, and can dramatically improve energy efficiency through combined heat and power applications.
