Power failures which often disrupt the smooth flow of traffic at many of Delhi's intersections will no longer be a problem at the Ring Road-Africa Avenue Crossing near Bhikaji Cama Place in South Delhi, thanks to the solar power system which has gone into operation from today. The solar power system, which will take on whenever power fails and keep the traffic lights going, was inaugurated by the Minister of State for Railways and Parliamentary Affairs, Mr. Ram Naik.
