Is domestic power generation turning to be a case of oversupply?
The latest government data is an indicator of why the power situation improved this summer. The power deficit had come down to 2.2 per cent between April-July 2015 and electricity generation rose 3.5 per cent in July.
But developers fear that with 82,241 MW of thermal power generation capacity under various stages of construction as of July 2015, it could soon lead to a situation of oversupply.
In April-July alone, according to data from the Central Electricity Authority, electricity requirement grew 0.1 per cent to 369,253 million units, and availability rose almost 2 per cent to 361,299 million units.
With the financially stressed state distribution utilities opting for long power cuts in the hunt for power purchase agreements at cheaper tariffs, the growth in supply in the country is outstripping requirement.
The average power tariffs on the spot markets like Indian Energy Exchange during the period has been down by over Rs 1 a unit as compared to the same months last year, while the volume of electricity traded on the exchanges has gone up by at least 400-500 million units every month apart from June.
In such a situation, generators are also not producing to their full capacity. Plant load factors of thermal power plants are down to 60.96 per cent so far in the current fiscal from 66.42 per cent in the previous year.
Experts differ on their views on the pace at which the country needs to add generation capacity.
A former NTPC Chairman and Managing Director recently said: “Provided you are not looking for windfall profits then investment in power generation is still viable. NTPC has been generating return on investment of 18-19 per cent quite comfortably. Higher than that may not be possible.”
