Wind Energy Programme in India
The Wind power programme
in India was initiated towards the end of the Sixth Plan, in 1983-84.
A market-oriented strategy was adopted from inception, which has led
to the successful commercial development of the technology. The broad
based National programme includes wind resource assessment activities;
research and development support; implementation of demonstration
projects to create awareness and opening up of new sites; involvement
of utilities and industry; development of infrastructure capability
and capacity for manufacture, installation, operation and maintenance
of wind electric generators; and policy support. The programme aims at
catalyzing commercialisation of wind power generation in the country.
The Wind Resources Assessment Programme is being implemented through
the State Nodal Agencies, Field Research Unit of Indian Institute of
Tropical Meteorology (IITM-FRU) and Center for Wind Energy Technology
(C-WET).
Wind in India are influenced by the strong south-west summer monsoon,
which starts in May-June, when cool, humid air moves towards the land
and the weaker north-east winter monsoon, which starts in October,
when cool, dry sir moves towards the ocean. During the period march to
August, the winds are uniformly strong over the whole Indian
Peninsula, except the eastern peninsular coast. Wind speeds during the
period November to march are relatively weak, though higher winds are
available during a part of the period on the Tamil Nadu coastline.
A notable feature of the Indian programme has been the interest among
private investors/developers in setting up of commercial wind power
projects. The gross potential is 48,561 MW (source C-wet) and a total
of about 11,807.00 MW of commercial projects have been established
until March 31, 2010.
The break-up of projects implemented in prominent wind potential
states (as on March 31, 2010) is as given below
