The tower for the WEG is tubular and must be coated with
corrosion proof layer so that it can withstand environmental
impact for at least 25 years life time. The towers must
have necessary arrangements to ensure safe access to nacelle.
of the farm
WEGs would be located in rows perpendicular to the predominant
wind direction with adequate spacing between the WEGs in
a row and between two rows to avoid interference and wake
effect. Spacing between two WEGs is defined in terms of
the number of times of rotor diameter of the WEGs. Normally,
spacing between two consecutive rows is kept more than the
spacing between two WEGs in a row to reduce wake effect.
Sitting the WEGs on a given area or preparation of layout
plan of WEGs on a given area is known as Micrositing of
WEGs. Micrositing is one of the most important activities
of designing a wind farm. This plays a vital role in generation
power from a wind farm. Proper layout of wind farm ensures
optimum harnessing of the wind power potential. Now-a-days
micrositing is done with the help of computer software programs.
There are many software programs available for micrositing.
has already identified potential technical consultants (such
as M/S Consolidated Energy Consultants
Ltd) who could carry out the micrositing and the
layout of the farm.
Estimation of annual generation is the one of the most important
activity for examining the feasibility of installing a wind
power project at any site. One of the key parameters that
affects the annual power generation at a site is the capacity
utilization factor of the wind electric generators. The
capacity utilization parameter is, in turn, dependent on
the mean annual wind speed and wind power density at the
site and the type of wind electric generator employed. The
Gujarat government in its tariff determination order dated
August 2009 takes an average CUF in Gujarat as 23%.
stage of the project
The project is currently in a pre development feasibility
study phase. The sites have been identified and the wind
resource at the site has been assessed through readings
available from government undertaken experiments. The land
which is currently owned by the government has been blocked
for MDGEPL and could be bought within 7 working days. Potential
EPC contractors have already been identified and quotes
actual construction activities of the project will start
once the funds are mobilized. A detailed project work/job
completion schedule with the various activities, timelines
and responsibilities would be provided to the investor.
In case the investor wishes to conduct a due-diligence on
the wind resource and other parameters at the site, full
support would be provided by MDGEPL subject to an NDA agreement
between MDGEPL and the investor.
