The Tamil Nadu Spinning Mills Association has urged the State power utility to do away with restrictions on power supply to industrial consumers.

The representation to the Tamil Nadu Generation and Distribution Corporation Ltd comes at a time when increasing wind power generation has helped bridge the prevailing power shortage that necessitated the restrictions in the first place.

The Association, the members of which own over 3,000 MW of wind power generation capacity (about half that installed in the State), said in the representation that over the last one week, wind power supply into the grid has crossed 30 million units. On Saturday, it was more than 60 million units, the highest ever in Tamil Nadu.

The power utility should consider withdrawing the prevailing restrictions on power supply and the additional restriction under consideration by the Generation and Distribution Corporation will hit wind generation as the wind mills will have to be stopped, backed down, from feeding power to the grid.

According to the Association, the additional restriction and control measures aim at making industrial units with High Tension power supply observe two-day power holiday in a week with one on Sundays and the other on a notified day for each region. But the validity of this proposal is being considered by the Tamil Nadu Electricity and Regulatory Commission, the power regulator.

The Corporation can enhance its revenue even as the windmill owners inject power to full capacities.

If the restrictions on power supply are not withdrawn, windmills will be forced to back out their generation during all power holidays due to lack of demand. This would be a waste of a green and clean power.

Wind mills were backed out on May 4 at a substation in the night. This shows that demand and supply have not been managed appropriately, the Association said.

Since 2008, the State has been facing a nearly 30 per cent shortage of power supply. Wind generation is a seasonal phenomenon with the season starting in April-May and lasting up to October.
