This tender has seen multiple deadline extensions amid inadequate bidder participation. The request for selection was first issued in February last year with a bid submission deadline of March 27, 2019. Another reason for reissuing the tender was that the updates were delayed due to the change of portal from TCIL (Telecommunications Consultants India) to the Bharat tender portal.

Data from the latest report by Mercom India Research – India Solar Market Leaderboard 1H 2019 – reveals that the top 10 rooftop solar developers in India accounted for 41.3% of total installations in the period while all others made up for 58.7%.

In a recently concluded auction, Kerala State Electricity Board Limited (KSEBL) awarded 46.5 MW of rooftop solar capacity to Tata Power, Waaree Group, and Inkel, a senior KSEBL official confirmed to Mercom.
