We have no basis to support or reject ICRA value. We have no data on cost per megawatt of windfarm and break-up of cost components.
Do we have a pure play WTG?
I did a small calculation of IRR for 250 MW @ 2.65/unit in SECI-1 for Inox.
For PLF @ 40%
Cost @5 crore/mw IRR = 18.3%
Cost @7 crore/mw IRR = 12.5%
For PLF @ 30%
Cost @5 crore/mw IRR = 13.3%
Cost @7 crore/mw IRR = 8.7%
Therefore cost of project, interest rate & PLF are critical to the success of project.
