Solar Auctions in 2018: Who Had the Biggest Share of the Pie?

ACME Solar, SB Energy, and Azure Power bagged 42 percent of awarded large-scale solar projects in 2018


India’s solar market is on a roll with over 24 GW of large-scale solar photovoltaic (PV) capacity installed in the country as of December 2018. According to Mercom India Research, over 13 GW of large-scale solar projects were auctioned and awarded in 2018, nearly three times more than the 4.5 GW awarded in 2017.

With the government focused on large mega-tenders and auctions, smaller developers have largely been left out due to financial constraints because auctions have become too big for them to bid.

Solar auctions of over 13 GW have not been spread evenly and a few large developers have won most of the projects. ACME Solar won the most auctions in 2018 (16 percent), followed by SB Energy with 15 percent, and Azure Power with a 11 percent. In 2018, approximately 67 percent of large-scale solar auctions were won by just seven developers.

SB Energy (SoftBank), a joint venture of Japan’s SoftBank, Taiwan’s Foxconn, and Bharti Airtel, was awarded 2 GW of large-scale solar PV projects to be developed across the country at an average tariff rate of ₹2.73 (~$0.0389)/kWh in 2018. In 2017, they won 600 MW of solar projects at a tariff range of ₹2.45 (~$0.0349)/kWh to ₹2.63 (~$0.0375)/kWh. Recently, SECI cancelled 2.4 GW of auctioned solar capacity due to a high price difference in tariffs, for which SB Energy quoted a tariff of ₹2.71 (~$0.0395)/kWh to develop 1.8 GW, but was awarded only 1.1 GW. The 1.1 GW project capacity is the single largest capacity bid in India in a reverse auction so far.

Azure Power, an independent solar power producer with an overall project portfolio of over 3 GW has been among the most active in the solar power auctions. With one of the largest project pipelines, Azure Power has been awarded approximately 1.4 GW capacity and tariffs ranging between a low of ₹2.53 (~$0.036)/kWh and a high of ₹3.34 (~$0.047)/kWh. Azure’s project development pipeline including rooftop projects now stands at 1.9 GW.
