Kerala State Electricity Board (KSEB) has secured an approval from the Kerala State Electricity Regulatory Commission (KSERC) for revision of electricity tariff to mobilise INR6.5bn (€77.7m).

The new tariff would be effective from this month.

The charges for all categories of domestic, other than those consuming up to 40 units, would have minor increase, The Economic Times reported.

Electricity consumed up to 300 units will have a hike between ten to 50 units, which would be billed under the present telescopic slab system, a mechanism where rate increases as the consumption rises.

The tariff will remain same for those who consume below 40 units.

Electricity consumed for agriculture and institutions like homes for poor people and orphanages are exempted from hike.

Meanwhile, domestic consumers using more than 300 units per month would be billed under non-telescopic slab system. The charges for 350 units will be INR5, INR5.50 for 400 units, INR6 for 500 units and INR7 for more than 500 units.
