For commercial consumers, DERC hiked the power rates by up to 11 per cent.
Despite the hikes, the regulator claimed the power bills of 80 per cent of the consumers, whose monthly consumption does not exceed 400 units, will witness some marginal decline as it has subsumed the power purchase adjustment cost (PPAC) for next three months. The PPAC surcharge will be reviewed in November.
The rates for consumption up to 400 units have been hiked by 2.5 per cent and DERC chairperson P D Sudhakar said their bills will actually come down by up to 5 per cent as PPCA has been withdrawn.
"The rates for consumption between 400 to 800 units has been hiked by 7.5 per cent but as PPAC surcharge has been withdrawn, there will be reduction of 0.5 per cent in power bills of these high-end consumers also," Sudhakar said.
The tariff for domestic consumers in the New Delhi Municipal Council areas has been hiked by up to 9.5 per cent but their bills will still be low as compared to other parts as rates were much less earlier. The NDMC directly supplies power to the residents.
For domestic consumption beyond 800 units a month in areas served by the discoms, the hike has been fixed at 15 per cent. Sudhakar said after PPAC adjustment, the hike will be around 7 per cent.
"The monthly tariff for over 80 per cent of the domestic consumers whose consumption does not exceed 800 units will come down as we have subsumed the PPAC surcharge for next three months. The PPAC surcharge will be reviewed in November," Sudhakar said, announcing the new rates which come into effect from today.
Sudhakar said those consuming up to 200 units in a month will have to pay Rs 4 instead of current Rs 3.90 per unit while the rates between 200 to 400 have been increased from Rs 5.80 to Rs 5.95 per unit.
Those rates of per unit between 400-800 have been hiked to Rs 7.30 from existing Rs 6.80 per unit.
A new slab of 800-1200 units has been created, and those consuming power in this category will have to pay Rs 8.10 per unit against current Rs 7. The per unit rate beyond 1200 units has been fixed at Rs 8.75.
The exact rates may vary in areas served by BSES Rajdhani Power Ltd, BSES Yamuna Power Ltd and Tata Power Delhi Distribution Ltd as PPAC for each of these three discoms were different.
