Dear Sirs,

TN govt has just announced that it expects Germany and/or TN Govt to spend ~1600 Crores on “evaluation” of wind power potential in TN. (I hope here is a mistake in The Hindu reporting this…!)

I am raising a discussion with my academic colleagues on what this money itself will fetch for TN as Solar power in KwH units. We appreciate the folks at TN govt are no fools, and yet we at the University have to be sure what we are doing with tax-payers’ money.

It should be quite simple for you to answer this question at this expenditure level. We would appreciate your advice on this(including the aspect of scaling up at this level of expense) before we do anything more about this project.

Thanking you,

It does seem a bit steep to spend 1600 crore on just evaluation. However, I am not familiar with the wind energy sector.

So purely by a capacity point of view: 1600 crore rupees can allow the government to set up solar power plant of about 210MW-270MW capacity.

Keep in mind for Tamilnadu:
Thermal 7527 MW
Hydro 2186 MW
Renewable 7979 MW
Nuclear 501 MW
TOTAL 18193 MW

So, about 1.5% of all Tamilnadu’s energy requirement can be met using solar instead of this evaluation.

Hope this helps.
