Kerala No. 1 Hota. State is very small. Trivandrum to Palakkad was doubled and electrified much before. Shoranur section was sanctioned late in 2011-2012 and took almost 5 years to complete. Even now also KSEB not providing electricity to Uppala TSS, correct me if I am wrong.
Tamil Nadu 3 major electrification works are in progress. 4th can start anytime. Then only few section will be left.
