Potential for Small Wind Power

The JNNSM way

JNNSM Solar installation target = 20000 MW

40% locations support wind power = 8000MW

50% of 8000MW by wind power for energy leveling = 4000MW

Same investment, same infrastructure = Higher energy

output & better ROI

In conclusion

Small wind turbines are low cost, low maintenance

and dependable alternative energy generators which

can be installed in short time in very little space and

virtually without any additional infrastructure.

The only large investment is in the acquisition of

wind speed data at 20M/ 30M height for the open

lands & roof top levels across the cities of India.
