Viability, implementation risks constrain outlook for wind energy sector; capacity addition to rise to 16 GW by 2023: Crisil

New Delhi: The country's wind energy sector is likely to see a slow growth with regard to capacity addition over the next five years, CRISIL Research said on Wednesday.The shift to a competitive bidding mechanism has slowed industry growth due to a significant fall in tariffs, triggering a decline in both bid response and profitability for original equipment manufacturers (OEMs), CRISIL Research said in a statement.[caption id="attachment_23842" align="alignleft" width="380"]
