The Metatron Danke Green Energy 100MW wind energy project

Metatron Danke Green Energy Pvt Ltd proposes to set up a 100 MW capacity wind farm in two sites in the state of Gujarat. This section describes in detail the various salient features of the project.

Site details
MDGEPL has identified two high potential sites, Boru and Meghpur, at Gujarat. The following exhibits indicate the location of the sites along the border of Gujarat and Rajasthan. The weather around the area is tropical and receives rain fall mainly from the north east monsoon during the October-December months.

Wind Resource
One of the most important aspects for a wind farm project is the estimation of wind resource of the site. The key parameters in this are the wind speed and the wind power density.

The local wind climate tends to be relatively constant over time. In other words, the energy content of the wind tends to vary less from year to year than, say, agricultural production. Typically, inter-annual wind energy production from a turbine varies with a standard deviation of around 10% of mean energy. In practice, however, wind turbines are not equally efficient at all wind speeds, and wind turbines have a generator of a finite size. At different wind speeds a wind turbine will be able to generate only a fraction of total rated power.

Land availability
Wind farms typically require large areas of land to be set up. This is because minimum distance needs to be maintained between the turbines. Typically in India around 3500 acres of land is required for setting up a 200MW wind farm with 133 wind turbines of 1.5MW rating. MDGEPL has secured around 1500 acres of land from the Government of Gujarat at these two sites (500 acres at Meghpur and 1000 acres at Boru). It has been able to secure the land at less than the market price due to its favourable relationship with the government. Currently the land has been blocked for MDGEPL and can be purchased in less than a week once the funds are mobilized.

Grid feed in points
A key constraint facing wind energy development internationally is bottlenecks in the electrical interconnection to the grid. One reason is that good wind resources (just like oil, gas and coal) are frequently found in remote, sparsely populated areas with (thermally) limited transmission capacity to other parts of the electrical grid, where electricity is consumed. Ideally wind farms need to be located close to grid feed in points. The proximity ensures that the capital costs required to evacuate the power by connecting to the grid is minimal. There are four Gujarat government state electricity board grids around the proposed sites. Three of the grids have a capacity of 66KV and the one of them is a larger grid with 200KV capacity.
