Load demand across Tamil Nadu

(THE HINDU | www.thehindu.com | Jul 26, 2017)

The State Load Despatch Centres (SLDC), which keep track of the entire grid operation in the State, are located in Chennai, Madurai and Erode.

And data from the SLDCs show that in the last one year, overall load increase has been recorded only in the area covering Chennai district and parts of Kancheepuram district by 100 MW.

In the rest of the State, there was little change.

Further, at 2,100 MW, Chennai North was the most intense power consuming region in the State.

The State’s power demand stands at around 13,200 MW per day covering 42 circles.

Of this, Chennai city alone accounts for nearly one-fourth. Power managers attribute the increase in electricity demand in the city to the increase in the number of air conditioners used by residents. Chennai has the maximum number of air conditioners in operation in the State, particularly in the domestic sector.

The electricity official said the highest demand of 15,343 MW registered on April 29 last year is yet to be touched this year. While the State electricity demand varies between 13,000 MW and 14,000 MW per day, the daily consumption is in the range of 275 million units (MUs) to 310 MUs.

The break-up of the 9 distribution regions shows that Chennai, combined with Chennai South and North regions, consumes 3,500 MW, Coimbatore 2,000 MW, Erode 1,600 MW, Vellore 1,400 MW, Tiruchi 1,400 MW, Tirunelveli 1,170 MW, Madurai 1,150 MW and Villupuram 980 MW.
