IIT Bombay: Chennai and Mumbai have high wind energy potential

The researchers studied the strength of the southwest wind during the active period and the break period of the monsoon

Of the six cities studied by Indian Institute of Technology, Bombay researchers, Chennai and Mumbai seem to have the highest potential to harvest wind energy during the time when the wind energy potential is very high (active period) during the monsoon period. Compared with these two cities, Indore, Ahmedabad and Kolkata have less potential to harvest wind energy; Delhi has the least potential. The results were published in the journal Meteorology and Atmospheric Physics.

The researchers studied the strength of southwest wind during the time of the monsoon and called the period when the wind energy potential is high, the active period and the period when the wind energy potential is low, the break period. The high wind energy potential during the active period also coincides with more rainfall; there is less rainfall and less wind energy potential during the break period.

“The idea behind the study was know what the implications of the active and break periods would have on energy demand scenario in the major cities,” says Prof. Subimal Ghosh from the Department of Civil Engineering, IIT Bombay, and one of the authors of the paper.

“We have not studied the impact of climate change on wind power in the six cities. Though we have studied both active and break periods, the focus of the work was on studying the impact of dry spells [break periods] during the monsoon on energy demand-supply,” says Prof. M.C. Deo from the Department of Civil Engineering, IIT Bombay, and one of the authors of the paper.

“Our study tries to answer the question if possible extraction of wind energy in the six cities can be relied on to meet the additional power demand during prolonged dry spells in the monsoon season.”
