Earth Hour and weather effect: Power demand down 1000MW

The capital’s power demand fell by 1,000MW on Saturday, according to the State Load Dispatch Centre. The “phenomenal” dip is attributed to the Earth Hour observed by Delhi on Saturday evening and the rain that brought the mercury down by a few notches.
As Delhi joined over 2,000 cities worldwide to observe Earth Hour by switching off lights between 8.30 and 9.30 pm, the cool weather made it a sweat-free experience. “The dip in temperature ensured a drop in power demand too. Coupled with the electricity saved during the Earth Hour, it brought down Delhi’s total consumption by over 1,000MW,” said a senior official of the power department. While the department is yet to ascertain as to exactly how much power did the Earth Hour save, officials estimate it to be 250 to 300 MW. “I was monitoring the situation last evening and there was a considerable dip in demand. We have to also take into account the cool weather on Saturday,” said Power Secretary Rajendra Kumar.
He added that power distribution companies played a big role in spreading awareness about Earth Hour. “On Saturday, we sent out over 6 lakh text messages,” said a BSES spokesperson. President welfare associations (RWAs) were roped in too. “We held workshops for various RWAs and requested them to observe Earth Hour,” said an NDPL spokesperson. The distribution companies are certainly overwhelmed by the response they received.
