Data: Evaluation of Power Distribution System

I came across an interesting set of data in the Central Electricity Authority's website. The table ranks the performance of power distribution system of distribution companies (DISCOMs)/ state electricity boards (SEBs) for the month of March 2005 of 22 urban agglomerations, with population more than 8 lakhs. Among the notable cities not in the list - Banglore, Mumbai City, Pune (due to non-furnishing of information).
The evaluation has been done based on the average number of trippings per feeder and the outage duration per tripping for 11 KV system.

Based on number of trippings per feeder
1. Kolkata (WB) - 0.13
2. Surat (Guj) - 0.16
3. Mumbai (Mah suburbs) - 0.31
4. Ahmedabad (Guj) - 0.34
5. Vishakapatnam (AP) - 0.64
6. Delhi (provider: NDPL)- 1.11
..

Based on outage (in minutes) duration per tripping
1. Jabalpur (MP) - 6.43
2. Coimbatore (TN) - 6.83
3. Chennai (TN) - 9.52
4. Mulund (Mah) - 9.73
5. Kochi (Kerala) - 12.19
6. Trichy (TN) - 14.93

What I was actually looking for was some data on inadequate capacity in feeder lines between newer generation centers (wind energy, etc) and load centers. The interest was sparked off by an article in The Hindu earlier this month.
