State power utility Tangedco purchased 4,140.96 million units of electricity from April 2021 to January 2022, at an average cost of ₹5.51 per unit.
In a petition filed with the Tamil Nadu Electricity Regulatory Commission (TNERC), Tangedco noted that in order to meet the demand in case of a shortage of wind and solar power or outages at its own thermal plants, power purchases were made through exchanges.
As per the data shared by Tangedco, it procured 961.38 million units at ₹8.15 per unit in October 2021, when a country-wide coal shortage made the headlines. It also noted that due to coal-related issues like domestic supply constraints and higher price of imported coal, electricity prices at power exchanges were high and very volatile.
