NTPC started selling surplus power at the day-ahead market through India Energy Exchange from June 4 this year. In the last 9 days the company managed to sell only about 9% of what it offered primarily because its power has been costlier than the market clearing prices on each day.
According to officials from the India Energy Exchange, NTPC offered some 30.5 million units of power over the last nine days but it managed to sell only about 2.74 million units - about 8.9% of what was offered.
"Power from thermal power stations at Vidhyanchal, Unchahar, Rihand and Dadri Power was on offer although the company has enlisted 13 stations - nine in North India and four in West. Power from some of these thermal power stations turned out to be costlier than the market clearing prices resulting in power offered by the company remaining unsold," a senior IEX official said.
Between June 4th and 12th the market clearing price hovered between Rs 1.9 per unit to Rs 2.6 per unit while NTPC's average energy cost, leaving out the fixed cost portion, is around Rs 2.25 per unit.
According to analysts, it will make sense for buyers to buy this power only if the market clearing prices touches or crosses Rs 2.25 per unit. NTPC total average cost is Rs 3.21 per unit.
NTPC offered the quantum of power that has been tied up by utilities for supplies to their consumers, but was not requisitioned by power utilities. It is accounted under power purchase agreements with the utilities and discoms need to pay the fixed cost portion of the power tariff even if it is not consumed. NTPC is, however, free to sell this power.
To facilitate utilization of un-requisitioned power, the power ministry in its amendment of the National Tariff Policy carried out in January 2016, incorporated enabling provisions to allow the central generating companies trade their unused power.
