policy shift by the Government of India and Government of Maharashtra
since 1983-84, has resulted in effective commercialization of wind
power sector. Out of the total installed capacity of 20492MW renewable
power in the country and Wind Power projects share 14156MW.
That puts India as the fourth largest
producer of wind power in the world:
Germany (27126 MW)
USA (40216 MW)
Spain (20674 MW)
India (14156 MW)
Denmark (3805 MW)
China (38280 MW)
Wind Potential Assessment
Assessed wind power
potential in the country is about 49130 MW, while in Maharashtra
it is 5439 MW. Sites with Annual Mean Wind Density above
200 W/m2 are considered suitable for wind power projects.
339 such sites have been identified in the country, of which
40 sites are in Maharashtra.Wind speed monitoring is in
progress at 211 Sites To instill confidence in the investors,
demonstration projects worth 7.34 MW installed capacity
were initiated in the state with support from MNRE, installed
by MEDA. Also, MEDA with its own funds has set up 3.75 MW
additional demonstration Wind Power Project as a source
of revenue generation. Thus the total capacity of demonstration
Wind Power Project by MEDA is 11.09 MW in Maharashtra.
policies of the Government of Maharashtra and technical
viability of demonstration projects have attracted private
investment of more than Rs 11895 crores in the wind sector
so far. Nearly 2309 MW of private wind power projects have
been installed in the State upto Mar-2011.
Commercial viability of wind
power projects is gradually increasing due to technological advancement.
Replacement of old 250 kW wind turbines of 30 m height with 1.0
MW single unit size of 50 m has provided an edge for attractive
investment. Higher wind power density due to increased height, lower
installation cost per MW and less land requirement makes a case
for choosing higher unit size of wind turbines. Fortunately, wind
turbines of 1 MW are being manufactured in the country and still
higher capacity units of 1.25 MW and 1.5 MW are under trial at Center
for Wind Energy Technology (C-WET), Chennai. The production capacity
of domestic wind turbines industry is 500 MW per year, which can
go up to 750 MW per year based on demand.
