Greater Mumbai and Kolkata have the best power distribution systems in India, according to a ranking by distribution companies, based on the number of trippings per feeder and period of feeder outages. The ranking was done by the Central Electricity Authority.
Despite the power shortage in Maharashtra, four circles in Mumbai were in the top 10 discoms in terms of performance. Four Tamil Nadu circles were in the top 20, along with BSES Rajdhani, which supplies power to south-west Delhi.
In a rating of discoms in the country, the CEA has placed Thiruvananthapuram and Thane next on the list.
The discoms have been rated by the CEA under its monthly evaluation of the power distribution system. The rating is based on the number of trippings and outage duration of 11 Kv feeders.
At present only towns with a population exceeding 800,000 are being evaluated. Gradually all towns in the country will be rated by the CEA which proposes to work out the reliability evaluation indices in line with international practice, said a CEA release.
Thirteen states did not furnish the information required for rating, namely Assam, Bihar, Chhattisgarh, Jammu and Kashmir, Jharkhand, Karnataka, Rajasthan and Uttar Pradesh. In Delhi, North Delhi Power Ltd did not submit the data.
Gujarat gave no information on the Rajkot, Surat and Vadodara circles while in Maharashtra, no information was furnished for Mumbai Suburban, Pune, Nashik, Aurangabad and Nagpur. In Madhya Pradesh, only Jabalpur submitted the required information.
