Get ready for frequent power cuts in the coming few days. Overdrawing of power by neighbouring states, coal and water shortage coupled with technical snags has led to reduction in power supply to the city.
The situation got critical on Monday with most states overdrawing from the national grid. Delhi experienced a shortage of close to 1,000MW of power on Monday.
"The grid situation was alarming today as the normal frequency of the grid which should be around 49.5hz went down to 48.6hz. Had it touched 48.5hz, the grid would have collapsed and there would have been a total blackout. To avoid this, distribution companies had to carry out load-shedding in various parts of the city," said a senior power department official.
The National Thermal Power Corporation (NTPC) said on Monday that several of its power stations have been hit by coal shortage, which is why it is supplying significantly less power than their installed capacities.
"Mining and loading of coal to our stations has suffered due to heavy rains and strikes which have affected coal production at several mines. Coal supply from these mines is almost about 70% of the NTPC's contracted quantity," said a NTPC official.
NTPC power stations at Dadri in Delhi, Unchahar in Uttar Pradesh, Singrauli and Vindhyachal in Madhya Pradesh, Farakka and Kahalgaon in east and Ramagundam and Simhadari in south have been affected due to coal shortage. The official added that before the onset of monsoons, NTPC had a coal stock of 5.3million tonnes to meet the requirement of 13.2 days, which has depleted drastically.
"Moreover, the Badarpur plant is generating less because of the shortage of water due to temporary closure of the Agra canal," added the official.
The UP Irrigation department said they had informed the NTPC about the canal's repair work due to which the water body has been temporarily closed.
"We had to repair the skin plates of the canal's barrage gates. The temporary closure will continue till October 25," said a senior official of the UP Irrigation department.
The worst affected areas were south Delhi - which included Amar Colony, Kailash Colony, Chittaranjan Park, Greater Kailash I and II and Defence Colony - and in east Delhi - which included areas like Mayur Vihar and IP Extension. These localities have been facing power cuts lasting up to four hours.
"We have never experienced such a situation at this time of the year. Carrying out daily activities like running the washing machine and filling up water have become difficult," said Richa Verma, a resident of south Delhi's Amar Colony.
