According to Mercom sources, the decline in renewable energy trading was due to the lower generation from wind and hydropower sources due to the seasonal changes and flooding in most regions of the country. Also, with solar generation mostly tied up in long-term power purchase agreements, the market experienced a considerable drop in overall renewable energy trading.
The total electricity volume traded at the Exchange was recorded at 9,260 MU in October, a 21% YoY increase. The overall volume, including Renewable Energy Certificates Energy Saving Certificates, was 9,483 MU during the month, an 18% YoY increase.
According to GRID-INDIA, the country’s energy consumption reached 139 billion units during the month, a 22% YoY increase due to the surge in demand driven by increased electricity consumption, below-average rainfall in October, and a lower base from the same month last year.
The surge in electricity trade was primarily due to distribution companies actively purchasing power on the exchange to meet the increased demand.
