The Kerala State Electricity Board (KSEB) will levy a thermal fuel surcharge in January, charging 7 paise per unit for bimonthly-billed consumers and 8 paise for monthly-billed consumers. This aims to recover an additional ₹18.45 crore spent on power purchases in November 2025 due to fuel price variations. The surcharge operates under regulations allowing cost recovery, with a current cap of 10 paise per unit. A proposal to remove this cap is under consideration by the Kerala State Electricity Regulatory Commission.
