FuelCell Energy's Record-Setting Power Plant Serves as Centerpiece of Earth Day Dedication at Montana's Billings Clinic; Montana Senator Conrad Burns Notes Ultra-Clean, High-Efficiency Plant Lowers Both Energy and Healthcare Costs

DANBURY, Conn.--(BUSINESS WIRE)--April 25, 2006--FuelCell Energy, Inc. (NasdaqNM:FCEL), a leading manufacturer of ultra-clean electric power generation plants for commercial and industrial customers, marked Earth Day 2006 with the dedication of a highly efficient Direct FuelCell/Turbine(R) (DFC/T(R)) at the Billings Clinic in Montana.

Joining officials from the Billings Clinic and FuelCell Energy to mark the plant's installation was U.S. Sen. Conrad Burns, R-Mont.

"This will not only help energy costs, but healthcare costs as well," said Burns. "We can find ways to develop energy and lower health care costs. I know what the impact is going to be, and it is all positive."

FuelCell Energy has been developing the DFC/T product following an initial Vision 21 Program contract award from the U.S. Department of Energy (DOE) in 2000. The DFC/T system integrates FuelCell Energy's 250 kilowatt Direct FuelCell(R) (DFC(R)) power plant with a 60 kilowatt microturbine from Capstone Turbine Corporation. Heat generated by the fuel cell is used to drive a modified microturbine to generate additional electricity. The supplemental microturbine power increases the electrical efficiency and reduces the cost of power generated -- without the use of additional fuel. The combined-cycle DFC/T system has no combustion which allows for ultra-clean performance.

"This fuel cell power plant will help reduce energy costs for the clinic, which, like other businesses, has seen a stiff increase in heating and power costs in the past five years," said Jim Duncan, Director of Development and Community Affairs for the Billings Clinic. "We really have to tackle cost containment from every possible angle, whether it is medical liability insurance or energy efficiency."

In February, FuelCell Energy announced this DFC/T power plant achieved a 56 percent electrical efficiency -- a record-setting performance in a sub-megawatt class - for over 800 continuous hours during initial testing at its Danbury facility. This product can serve markets that require high efficiency electrical generation.

About FuelCell Energy

FuelCell Energy develops and markets ultra-clean power plants that generate electricity with higher efficiency than distributed generation plants of similar size and with virtually no air pollution. Fuel cells produce base load electricity giving commercial and industrial customers greater control over their power generation economics, reliability and emissions. Emerging state, federal and international regulations to reduce harmful greenhouse gas emissions consider fuel cell power plants in the same environmentally friendly category as wind and solar energy sources -- with the added advantages of running 24 hours a day and the capacity to be installed where wind turbines or solar panels often cannot. Headquartered in Danbury, Conn., FuelCell Energy services over 40 power plant sites around the globe that have generated more than 94 million kilowatt hours, and conducts R&D on next-generation fuel cell technologies to meet the world's ever-increasing demand for ultra-clean distributed energy.
