Bills of those consuming less than 800 units will reduce because power purchase cost adjustment charges (PPAC) has been scrapped till November. PPAC formed 6%-8% of a consumer's bill. The bill for 'common areas', like lifts or parking spots in a colony, will be fixed under 200-unit slab. Earlier, common areas were charged under the highest slab.The new rates will result in 10 paise increase for first 200 units, 15 paise for 201 to 400 units and 50 paise for 401 units and above in the the electricity bills. The Delhi Electricity Regulatory Commission (DERC) had received a representation from the power distribution companies seeking a power tariff increase as part of the power purchase adjustment charges. The power regulator had said it had received a representation from the three power distribution companies. High power tariffs and promises to reduce it considerably was a major rallying point for a number of parties during the recently concluded Delhi Assembly elections. Both the Aam Aadmi Party (AAP) and the Bharatiya Janata Party (BJP) during their campaigns had promised that if elected to power, they would slash power tariffs considerably. While AAP had said it would bring down the power bills by 50%, the BJP had claimed that it will reduce power tariff by 30%. The power distribution companies have also filed their aggregate revenue requirements to decide power tariff for the next year. “Their claims are being examined but we have a few queries and have sought a reply from them,” said a senior official. Discoms claim that they have to pay power suppliers such as National Ther mal Power Corporation and Delhi’s Indraprastha and Pragati on a monthly basis while it took them at least two years to recover the expenses from consumers, hence a system of PPAC wherein tariff increased quarterly is helpful.
