Indian firm Acme Solar has matched its record – the lowest ever solar bid in India – once again during Solar Energy Corporation of India’s (SECI) 3GW Interstate Transmission System (ISTS) solar auction.

The firm is set for 600MW of capacity at a price of INR2.44/kWh (US$0.036), a tariff with which it bagged 600MW of capacity in the recent 2GW ISTS solar auction from SECI and 200MW in Rajasthan in May 2017, the first time such a low tariff had been reached in India.
