Branford High School first school in Connecticut to install a clean UTC Power on-site tri-generation power system

SOUTH WINDSOR, Conn., Aug. 29, 2007 – UTC Power, a United Technologies (NYSE: UTX) company, today announced that Branford High School in Branford, Connecticut, has selected a PureComfort® tri-generation system to provide on-site power, cooling and heating at the 1,200-student facility.

This ultra clean combined cooling, heating and power system also will enable the high school to double as an emergency shelter by having an on-site power source capable of grid-independent operation.

PureComfort® systems are extremely energy efficient. They can achieve an overall energy utilization of up to 90 percent – far greater than the 33 percent typical of the electrical grid. These systems also reduce a customer’s carbon footprint because of their higher fuel utilizations and the use of natural gas to generate electricity, rather than coal or oil.

The system’s design also ensures a reduction in pollutant emissions such as smog-forming nitrogen oxides, and there are no ozone-depleting refrigerants. Compared with generating power from the grid, the system will save more than 2.5 million gallons of water annually, nearly enough water to fill four Olympic-sized swimming pools.

According to Mark Deming, director of Facilities for the Branford School District, “The UTC Power system was the sensible choice for us; it can provide power, cooling and heating simultaneously in a clean, green, efficient manner. Plus, we know we can count on having backup power if there’s a grid failure.”

The UTC Power system will be the first in the state to provide simultaneous heating and cooling, with no seasonal changeover required, using the hot exhaust from its natural gas-fired microturbines to drive a double-effect absorption chiller. The system will lower the high school’s energy bills and provide positive cash flow for the school district.

United Technologies Corp., based in Hartford, Conn., provides high-technology products and services to the building and aerospace industries.
