Renewable Energy Trading at IEX Down 11% in October, Weighted Average Price Drops

A total of 358,000 RECs cleared during the month, registering a decline of 39% MoM


The Indian Energy Exchange (IEX) traded 403 million units (MU) of renewable energy in October 2022, an 11% decrease month-over-month (MoM) compared to 454 MU traded in the previous month.

The exchange traded 7,972 MU of energy during the month. The total volume on the exchange in October was lower by 13% on a year-over-year (YoY) basis due to the high volume base of last year and lower by 2% on an MoM basis due to reduced REC trading.

Improved domestic coal supply led to easing supply-side constraints, resulting in lower prices on IEX. The average clearing price in the Day-Ahead Market was ₹3.83 (~$0.046)/kWh in October, which was lower by 32% on a MoM basis and 52% on a YoY basis.

The exchange suggests that a further correction in prices due to improvement in coal availability and reduction in demand due to the onset of winter is expected to provide an opportunity for cost optimization by distribution companies and open-access consumers, resulting in increased volumes on the exchange in the future.

According to the power demand data published by the National Load Dispatch Center, the energy consumption at 115 BU during October 2022 increased by 1% on a YoY basis, and on an MoM basis, it declined by 10%.
