Power generation from wind has emerged as one of the
most successful programmes in the renewable energy sector, and has
started making meaningful contributions to the overall power
requirements of some States.
Energy is a major input for overall socio-economic
developement. Use of fossil fuels is expected to fuel the economic
development process of a majority of the world population during
the next two decades. However, at some time during the period
2020-2050, fossil fuels are likely to reach their maximum
potential, and their price will become higher than other renewable
energy options on account of increasingly constrained production
and availability. Therefore, renewables are expected to play a key
role in accelerating development and sustainable growth in the
second half of the next century, accounting then to 50 to 60% of
the total global energy supply.
After the creation of a seprate Ministry in 1992,
special emphasis was given in the Eighth Plan to generation of
grid quality power from renewables. The total installed capacity
of power from renewables today stands at nearly 1350 MW with
contribution from wind power of nearly 1000 MW.
Wind power installations worldwide have crossed 78728
MW producing about 54 billion KWh of energy annually. A total
capacity MW has been installed in Germany(20,952 MW), Spain (12,500 MW), USA (12,376 MW), India (7140 MW), Denmar(3136 MW) and in Europe. India is now the fourth largest wind
power generator in the world after Germany, USA and Spain.
The State of the World 1998, a world-watch Institute
Report on progress toward a sustainable society, released earlier
this year, has noted that renewable energy production in the world
is expanding rapidly. Wind generation is the fastest growing
energy source in this decade and is expanding at 25% per year. The
Report recognises India as a new "Wind Superpower". With
declining trend of cost and increase in the scale of wind turbine
manufacturing, wind promises to become a major power source
globally in the first few decades of the new millennium.
MNRE(Ministry of New and Renewable Energy)
are implementing the world's largest wind resource assessment
programme, which forms the backbone of their wind exploitation
efforts. Preliminary estimates indicate a potential of about
45,000 MW. Scientific surveys are being intensified to identify
specific viable and potential sites. A recent study undertaken to
re-assess the potential, places it at about 60,000 MW. Assuming a
grid penetration of 20%, a technical potential of about 15192 MW
is already available for exploitation in the potential States. 160
sites have so far been identified in 13 States. Survey work is in
progress in 24 States / UTs. The States of Rajasthan and West
Bengal have also shown wind potential.
Today, we have a wind power installed capacity of 7320
MW in the country, out of which about 7250 MW is accounted for by
commercial installations. About 33.5 billion units of electricity
have been fed to the grid so far. A good local production base for
wind turbines now exists in the country, with 8 manufacturing
companies active in this sector.
Today, the capital cost of wind power projects range
between Rs. 4 to 5 crores per MW. This gives a levelised cost of
energy generation in the range of Rs. 2.00 to Rs. 2.50 KWh, taking
into consideration the fiscal benefits extended by the Government.
The government has introduced a package of incentives
which includes tax concessions such as 80% accelerated
depreciation, tax holidays for power generation projects, soft
loans, customs and excise duty reliefs, liberalised foreign
investment procedures, etc.
IREDA and other financial institutes mostly in the private sector are playing a significant role in promoting
Renewable Energy Projects, in general and Wind Energy Projects in
particular |
