The floodlights on the High Court end tower at Eden went off yesterday causing a hold-up in play. Even as the CESC blamed CAB’s faulty maintenance for the disruption, the latter alleged it was improper power supply by the CESC that caused the floodlights to go out.

The CAB today handed over log-sheets to Kolkata police commissioner Gautam Mohan Chakraborti, clarifying that the lights went off because of faulty electricity supply.

The Indian Express has learnt that the power supply readings provided in CAB’s log-sheet entries suggest that the CESC’s supply to the floodlight tower in question had fallen short well below the bare minimum power supply required for the floodlights to remain on.

“We require a minimum of 6,100 kilowatts from the CESC for our transformers at Eden to run the towers. But last night, the supply fell to 6,020 kilowatts and consequently, the lights went off. And as known, it takes 20 minutes for the lights to start functioning after proper power supply is restored,” CAB administrator Chitrak Mitra told The Indian Express.

Mitra is in-charge of the committee formed by Dalmiya to investigate the blackout. “Every detail has been mentioned in the log-sheet entries and it’s for everyone to see. Other than improper power supply from the CESC, there can be no other reason for the blackout,” said Mitra.

CAB joint-secretary Biswarup Dey handed over the paperwork to the Kolkata police at today’s meet, he added.

Chakraborti, meanwhile, said that a one-man committee comprising Special Additional Commissioner (Armed Police) Debasish Roy has been instituted to look into the matter.

“He will submit the report in the next seven days,” said Chakraborti.
