Foreword

IndIa has long played an Important role in the world’s wind energy
market. already established in the 1990s, by 2005 it had developed into the world’s
fourth largest market, and the only sizeable market in asia at that time.

In 2008, India was the country that brought online the third largest amount of wind
energy, after the uS and China, and it now ranks fifth in total installed capacity with
9,645 mW of wind power installed at the end of 2008.

a strong domestic manufacturing base has underpinned the growth of the Indian wind
energy market. the Indian wind turbine manufacturer Suzlon is now a recognised player
on the global market, and many international companies are established in India.

India has a great untapped potential for wind energy. according to official estimates, the
country’s total wind energy resource amounts to 48 gW of installed capacity, but some
experts think that this figure is on the conservative side, and that technological
improvements could significantly increase this potential.

the positive development of wind energy in India has mainly been driven by progressive
state level legislation, including policy measures such as renewable portfolio standards
and feed-in-tariffs. at the moment, there is no coherent national renewable energy
policy to drive the development of wind energy. this is urgently needed to realise the
country’s full potential and reap the benefits for both the environment and the economy.

the Indian government is currently considering the introduction of a national renewable
energy policy, so this report comes as a timely reminder of how important a role wind
energy could play in securing India’s energy security, curbing its CO2 emissions,
providing new employment and boosting economic development.

as can be seen by the Indian Wind energy Outlook, the wind industry, both domestic and
international, stands ready to do its part in achieving an energy revolution in India. With
sufficient political will and the right policy frameworks, it could do even more.
