Turboden Enters UK Market With Two Organic Rankine Cycle Biomass Power Plants

British Sky Broadcasting and Heathrow Airport embrace renewable energy

EAST HARTFORD, Conn., May 2, 2012 /PRNewswire/ --Turboden recently entered
the UK market with awards for two biomass-fueled Combined Cooling, Heat and
Power plants for two of the country's most well known institutions - British
Sky Broadcasting and Heathrow Airport. Both will receive clean, carbon-neutral
power by utilizing Turboden Organic Rankine Cycle (ORC) turbogenerators.
Turboden is a Pratt & Whitney Power Systems company, and Pratt & Whitney is a
United Technologies Corp. (NYSE: UTX) company.

"Traditionally, Turboden has developed projects in which ORC units were
suitable for district-heating in small or medium-sized villages," says Paolo
Bertuzzi, general manager, Turboden. "With these larger scale trigeneration
projects, Turboden is delivering cost-saving renewable energy solutions for
some of the UK's most prominent institutions. We're proud to now be able to
enter the UK market."

British Sky Broadcasting Ltd (BSkyB) is a public satellite broadcasting
company operating in the United Kingdom and Ireland. It is the largest pay-TV
broadcaster in the United Kingdom with over 10 million subscribers. BSkyB is
developing a 1 MW CCHP plant as an integral part of its carbon cutting
emissions plans for its new studio, editing and transmission and data
facility.

The main BSkyB campus in Hounslow, West London, will receive 32 tons of wood
chips per day from local businesses within 25 miles of the facility. The wood
products are burned at temperatures exceeding 1,000 degrees Celsius to heat
thermal oil systems, which drives the 1 MW ORC turbine. Lower-grade heat is
then recovered to create chilled water for cooling and the remaining heat is
used for hot water.

One of the key initial objectives of the ORC plant was to offset at least 20
percent of the new facility's C02 emissions, but the plant has doubled this to
up to 40 percent since it was installed last December, according to Steve
Holford, head of engineering projects and energy at BSkyB.

BAA Airports Limited, which operates six airports in the UK, including London
Heathrow, is installing Turboden's second ORC plant in the UK. London Heathrow
is one of the busiest airports in the world, serving some 180 destinations in
more than 90 countries. Turboden's biomass-fuelled CCHP ORC unit at London
Heathrow will use clean wood waste to produce 1.8 MW of electricity and 8MW of
thermal heat and cooling to Terminals T2a and T2b, and heat only to Terminal
T5. Construction of the Heathrow plant is almost complete and start-up is
expected by summer.

Similar trigenerative CCHP ORC plants have recently been installed at a public
hospital in Every, France, and another CCHP ORC plant is now underway for a
five-star hotel in Poland.

"At a time when the UK government is formally assessing the potential of
renewable electricity and heating technologies in the country through 2030, we
are showcasing the flexibility and cost effectiveness of biomass-fuelled
plants," added Bertuzzi. "These projects provide a significant example of how
biomass can contribute to meeting the country's renewable energy goals."

Turboden's ORC technology utilizes heat from several sources including
biomass, geothermal, concentrated solar power, and by recovering heat from
industrial processes, engines and gas turbines. The technology is unique, in
that it uses an organic fluid instead of steam to drive a turbo-generator,
which can range in nominal output from about 1 to 10 MW and up. The system
employs a closed-cycle process that uses relatively low- to
moderate-temperature heat sources to generate electricity. These ORC systems
are driven by a simple evaporation process and are entirely enclosed, which
means they produce virtually noemissions.

Turboden, a Pratt & Whitney Power Systems company, is an Italian company and a
global leader in the design, manufacture, and servicing of Organic Rankine
Cycle (ORC) turbogenerators, which harness heat to generate electrical power
from renewable sources, including solar energy, biomass, geothermal energy and
waste heat. Turboden and Pratt & Whitney combined have over 250 ORC power
plants sold in more than 20 countries and offers standard turbogenerators from
1 to 10 MW and up. Turboden is a specialist in ORC technology. www.turboden.it

Pratt & Whitney is a world leader in the design, manufacture and service of
aircraft engines, space propulsion systems and industrial gas turbines. United
Technologies, based in Hartford, Conn., is a diversified company providing
high technology products and services to the global aerospace and commercial
building industries.
