The Indian Energy Exchange (IEX) traded 377 million units (MU) of renewable energy in December 2022, an 6% increase month-over-month (MoM) compared to 354 MU traded in the previous month and a 2% year-over-year (YoY) increase.
This included the energy traded in the Green Day-Ahead Market (GDAM) and Green Term-Ahead Market (GTAM).
The exchange traded 8,452 MU of energy during December, including renewable energy certificates (REC) equivalent to 487 MU. The overall volume on the exchange saw a 9% MoM increase. However, it declined by 7% year-over-year due to high REC traded volumes in the previous year.
IEX recorded 24.2 BU volume and saw a 5% quarter-over-quarter (QoQ) growth across all its market segments in the third quarter of the fiscal year 2023.
The exchange said that improving coal inventory and the onset of winter will reduce the clearing price further, which is expected to provide cost optimization opportunities to power distribution companies and open access consumers.
According to data from the National Load Dispatch Center, the energy demand met in December 2022 was 121 BU, a 10% increase from the previous year. The exchange achieved 1,130 MU volume in the third quarter of the financial year (FY) 2022-23, a decline of 6% YoY.

In December 2022, the volume of the Day-Ahead Market (DAM) decreased by 2% MoM to 5,001 MU. The DAM volume was also down 8% from the previous year due to high prices caused by a constrained supply.

The Real-Time Electricity Market achieved 1,763 MU volume during the month, registering 25% MoM and 17 YoY growth. There were 670 participants in this segment. According to IEX, the consistent growth of the real-time electricity market indicates the growing reliance on distribution utilities and industries to achieve the power demand-supply balancing in real-time most efficiently.
