Seven UTC fuel cell systems to power world’s largest fuel cell installation at Verizon facility

SOUTH WINDSOR, Conn., March 20, 2002 — UTC Fuel Cells, a unit of United Technologies Corp., Wednesday announced the sale of seven PC25™ fuel cell power plants to Verizon to provide primary power for a critical call-routing center on Long Island, New York.

The seven units, which each produce 200 kilowatts of electricity and 900,000 Btus of usable heat, will form the largest fuel cell installation in the world, surpassing the PC25 installation at the Connecticut Juvenile Training Center in Middletown, Conn.

“Verizon’s decision to install PC25 fuel cell power plants at this facility demonstrates the ability of our fuel cells to meet critical power needs cleanly and reliably,” said UTC Fuel Cells President William Miller. “We are proud to add Verizon, one of the communication companies in the world, to our long customer list.”

Verizon will install the units at a 332,000 square-foot facility in Garden City that delivers local phone service to some 40,000 Verizon customers on a 24-hour basis. The facility is also home to more than 1,000 employees who handle various functions, including answering customer calls.

The fuel cells, which together will generate 1.4 megawatts of electricity, will provide primary electrical power for the facility. Verizon also plans to install four natural gas powered generators to operate in parallel with the fuel cells as a hybrid system that can generate up to 4.4 megawatts of electrical power. The generators will serve as backup power, along with the electrical grid and batteries

Last year, UTC Fuel Cells installed six units at the Connecticut Juvenile Training School in Middletown. The units form a 1.2-megawatt microgrid to provide power to buildings on the campus. This is currently the largest fuel cell installation in the world.

A fuel cell is an electrochemical device that combines hydrogen, or hydrogen-rich fuel, and oxygen to produce electricity, heat and water. Fuel cells operate without combustion, making them almost pollution free. While a traditional generating system produces as much as 25 pounds of pollutants to generate 1,000 kilowatt-hours of electricity, the PC25 power plant produces less than an ounce.

UTC Fuel Cells has manufactured the PC25 power plant since 1991 and delivered more than 245 to customers in 19 countries on five continents. Those power plants have together accumulated nearly 5 million hours of operation.

UTC Fuel Cells produces and develops fuel cells for commercial, transportation, residential and space applications.
