About WBSEDCL tariff structure

West Bengal State Electricity Distribution Co. Ltd. bills domestic consumers using a telescopic slab structure. Each slab applies only to the units within that range, so adding a few more units never reprices your earlier (cheaper) units.

Beyond energy charges, the WBSEDCL bill includes a fixed charge of ₹30/kW/month on your sanctioned load, an FAC pass-through of ₹0.00/unit (revised monthly), and West Bengal electricity duty of 0%.

We verify WBSEDCL rates against the latest SERC tariff order quarterly. Last verified: 2026-04-22. Original source: official tariff order.
