Wind generation falls, TANGEDCO may Purchase Power

TNN | Aug 16, 2017, 08.34 AM IST CHENNAI: Wind power generation fell to 495MW on Monday night from nearly 3000MW a few days ago. Monday being a holiday due to Janmashtami, power demand in the state was less than 10,000MW, and with the help of standby thermal units, Tangedco was able to supply power.

Wednesday could be a challenge for the discom when the demand is expected to cross 13,000MW. Without wind power generation and both the units of Kudankulam, it could be tough to manage. Discom officials, however, are confident of meeting the demand by purchasing power from the market.

“The forecast on wind power said the generation will be lower due to rain in southern regions. Based on that, we started power generation from our own thermal units as well as other private thermal units in Tamil Nadu which were put on standby mode,” Tangedco distribution director M A Helen told TOI.

There is no news about the two units in Kudankulam. “Kudankulam officials are not forthcoming with information as to when the two units will be restarted, but two units in Vallur are working and from there we are able to get about 700MW,” said the director.

“If the demand increases beyond our present generation capability, say to 13,000MW, we will purchase power from the market where it is available at lower tariff. We will have to bid for the power early so that we will be able to purchase at a lower tariff,” she said.

The second unit of Vallur, which was shut due to a problem in the boiler, restarted on Tuesday evening.”The third unit, which was shut due to fire two months ago, is not yet ready. Two other units are generating power, mostly to the full capacity of 500MW each. Tamil Nadu will be getting 375MW each from the two units,” said an official at the Vallur joint venture unit.

The discom is hopeful of meeting a demand of up to 14,000MW. “As of now, the demand is around 13,500MW and it is mostly due to residents using air conditioners in Chennai and Coimbatore. Once the weather gets better, the demand is likely to reduce,” said the Tangedco official.
