Power companies depend heavily on coal to run smelters and generate electricity.
Shares of Reliance Power tumbled 6.79 per cent, while Adani Power lost 6.44 per cent on the BSE.
Among others, Tata Power fell by 2.77 per cent, NHPC (-1.87 per cent), Torrent Power (-1.84 per cent) and NTPC (-0.63 per cent).
"Shares of power generation and power distribution companies extended Monday's losses triggered by a Supreme Court ruling that all coal mining licenses distributed since 1993 are illegal," said Jayant Manglik, President-retail distribution, Religare Securities.
However, the consequences arising from the verdict of such coal blocks will be considered after further hearing by the apex court.
