Nearly a lakh electricity consumers in West Bengal, fed by the state distribution utility CESC will bear the brunt of a tariff revision approved by the electricity regulator today.

Though the regulator has not escalated tariff of the West Bengal State Electricity Distribution Company (WBSEDCL) from the existing levels of 6.07 a unit on average, the discom is allowed to recover approximately Rs 1,200 crore from consumers as arrears for 2011-12.

According to sources, the arrears cropped up as the State Government dilly dallied in allowing the discom to file the tariff revision petition, leading to under-recovery. “We are now allowed by the regulator to recover the cost push for 2011-12,” a company source said. He, however, added that the arrears for 2011-12 would be collected in 48 monthly instalments to ensure consumer interest.

Nearly 25 lakh consumers of the privately run CESC Ltd, are marginally hurt as the regulator awarded a 6 paise per unit rise to mitigate increase in fuel prices, freight and excise duty revision on power purchase during the fiscal.

Acording to company sources, the approximately 1 per cent tariff hike will leave a positive impact of Rs 55 crore annually on CESC’s finances.
