Abstract:
Wind power production has grown
substantially in the world over the past two
decades, making wind the fastest-growing non fossil energy source. The growing rate of
installed capacity of wind power was reported
to be less than 20% from 2000 to 2019 and
anticipated to increase by another 50% by the
end of 2023. Wind resources in Sri Lanka show
varied wind energy potential in different
regions. Adapting new wind technologies, such
as large turbines and tall towers, can optimize
wind generation in different regions while
increasing the wind power potential for the
country. In this study, the wind tower hub
height is used as the primary factor to evaluate
the impact of new technologies. It is shown that
by increasing the tower height by 20-40 m over
the standard 80 m hub height, wind power can
be generated at a competitive cost in Sri Lanka.
