"It is a matter of grave concern that even two weeks after the May 30 thunderstorm, which the power department officials are blaming for the destruction of power cables and towers, no concrete action plan to prevent such a situation from arising in the future appears to be in place," the party said in a statement.
The party also alleged lack of accountability in the functioning of power discoms and blamed Congress and BJP for it.
The party demanded that steps taken by Delhi administration and Union Power Ministry for the emergency electricity restoration to ensure lesser power outages in the national capital be made public.
"The silence of both, the BJP and the Congress on the functioning of discoms and their inability to ensure uninterrupted power supply, give rise to reasonable apprehension about their close relations with these discoms," the party said.
