Power-hungry neighbours starve Capital

Delhi has sought the Centre’s intervention to make other North Indian states stop overdrawing power.
Chief Minister Sheila Dikshit has written to Union Power Minister Shushilkumar Shinde that an unstable Northern Grid, caused by over-drawals by neighbouring states, is forcing power cuts in Delhi even when the Capital had enough power.
“Load-shedding is taking place not because of power shortage but because of under frequency relays in the Northern Grid caused by overdrawing of power,” she said.
When constituent states draw more power than their quota of power from the Northern Grid the frequency at which the grid operates falls, forcing all constituent states to shut down their systems temporarily to restore the operable grid frequency of 50 Hz.
But even if overdrawing by states is reigned in, the Capital’s “power preparedness” this summer has taken a serious jolt because the Centre has not yet sent the 350 MW — as good as 10 per cent of Delhi’s average peak demand — Delhi had been asking for and had banked on.
Power secretary Rajendra Kumar said, “We have asked the Centre for more power but that is yet to arrive.”
The demand for power this summer is expected to easily cross 4,500 MW but Delhi has already started struggling at 3,900 MW. Kumar claimed some of the states had directed their power generating companies to not sell power outside.
“It has also affected us as our discoms had entered into agreements with power generating units of some other states for supplying power to Delhi,” he said.
While Monday did not see any under-frequency relays, the weather cooled down significantly following a welcome spell of rain. The peak demand was just 3,133 MW.
