Bahrain World Trade Center (also called
Bahrain WTC or BWTC) is a high
twin tower complex located in Manama, Bahrain.
towers were built in 2008 by the multi-national architectural firm
. It is the first skyscraper
in the world to integrate wind turbines
into its design.
50-floor structure is constructed in
close proximity to the King Faisal
Highway, near popular landmarks such as the towers of BFH, NBB,
Lulu and the scenic Pearl
Roundabout. It currently ranks as the second
tallest building in Bahrain, after the twin towers of the

The two towers are linked via three skybridges
, each holding a 225KW
, totalling to 675kW of
wind power production. Each of these turbines measure in diameter,
and is aligned north, which is the direction from which air from
Gulf blows in.
-shaped buildings on either side are designed to
wind through the gap to provide
accelerated wind passing through the turbines. This was confirmed
by wind tunnel
tests, which showed that
the buildings create an S-shaped flow, ensuring that any wind
coming within a 45° angle to either side of the central axis will
create a wind stream that remains perpendicular to the turbines.
This significantly increases their potential to generate
The wind turbines are expected to provide 11% to 15% of the towers'
total power consumption, or approximately 1.1 to 1.3 GWh
a year. This is equivalent to providing the lighting
for about 300 homes annually. The three turbines were turned on for
the first time on the 8th of April, 2008. They are expected to
operate 50% of the time on an average day.
