Rohit Bajaj, Head and Senior Vice President- Business Development at IEX, said, “We are very optimistic about the growing potential of the green market and have achieved a cumulative trade volume of around 3.5 BU to date. The GTAM commenced in August 2020, and it has been doing well.”

“The GDAM has just become operational in October 2021, and we hope this market will also do exceptionally well. Our focus is on capacity building, and we are working closely with our buyers and sellers and other stakeholders to generate further liquidity in the market. The green market has today emerged as a critical avenue with more and more utilities and commercial and industrial consumers participating to meet their energy and renewable purchase obligation (RPO) requirements in an integrated, flexible, and competitive manner,” he said.

Day-Ahead, Term-Ahead, and Real-Time Electricity Market

IEX said the average price was ₹12 (~$0.16)/kWh in the first fortnight of October 2021.
