Indian power companies saw considerable jumps in the market value of their stocks on Monday, in wake of resignation of Arvind Kejriwal as chief minister of Delhi on Friday.

Activist-turned-politician Arvind Kejriwal, who was elected in part on a promise of lowering electricity tariffs, quit last Friday due to obstacles that Congress and BJP allegedly put in the way of an anti-corruption bill.

Stock in Tata Power Company Ltd gained 2.6 per cent in early morning trade on Monday, while stock in Reliance Infrastructure Ltd gained 0.4 per cent.

In December, Kejriwal had asked the state auditor to look into the accounts of power distribution companies (discoms) to see if they were profiteering. He had also asked the state's power regulator to revoke the licenses of the discoms in case they fail to supply power at affordable rates.

It may be noted here that billionaire Anil Ambani-led Reliance Infrastructure Ltd operates two discoms in the national capital in a joint venture (JV) with the Delhi government.

Shares of power companies also gained a considerable momentum after Finance Minister P Chidambaram announced in his interim budget that power sector would add 50,000 MW of capacity.

At 11:40 a. m., NTPC jumped 0.83 per cent; while Tata Power and Adani Power gained 3.25 per cent and 3.19 per cent, respectively.
