The Delhi Electricity Regulatory Commission (DERC) Chairman P D Sudhakar said the average hike is 20.87 per cent in all categories and domestic tarrif has been hiked by 24.15 per cent.
The regulator had in August last year hiked the tariff by 22 per cent hike for all categories of consumers. The tariff was hiked by five per cent in February and by upto two per cent in May this year to adjust the power purchase cost of the distribution companies.
All the three power distribution companies, BSES Rajdhani Power Ltd, BSES Yamuna Power Ltd and Tata Power Delhi Distribution Ltd have been pushing for a hefty hike citing their "severe" finacial condition.
Several areas in Delhi have been facing severe outages for the last five days after state-run NHPC cut supply of 200 MW power to BSES Rajdhani Power Ltd for failing to pay up dues of over Rs 225 crore. Another power generation firm Damodar Valley Corporation has threatened to stop 280 MW supply to the discom if it did not make payment of around Rs 330 crore.
The two BSES discoms have said the situation has worsened due to absence of a cost-reflective tariff structure.
The announcement by the regulator came a day after Chief Minister Sheila Dikshit had batted for hike in tariff saying the DERC will have to take a realistic view of the situation while finalising the new rates.
