Sikkim electricity bill calculator — how your bijli bill is built
The Energy & Power Department of Sikkim bills on SSERC slabs of ₹2.10 (0–50), ₹3.10 (51–100), ₹4.10 (101–200), ₹4.60 (201–400) and ₹5.10 (401+) per unit with a ₹50/month fixed charge (single-phase) and 5% electricity duty — the FY 2025-26 order of 27 March 2025 added roughly ₹1/unit across the board.
Gangtok to the border towns share one tariff; hydro-abundant Sikkim keeps rates among India's lowest. The FY 2026-27 public hearing was held on 17 June 2026 but the final order is pending, so the FY 2025-26 rates continue.
Example: your Sikkim bill for 250 units
Take a Sikkim household using 250 units in one month on Energy & Power Dept. The telescopic energy charge is 50 × ₹2.1 + 50 × ₹3.1 + 100 × ₹4.1 + 50 × ₹4.6 = ₹900.00. Add the fixed charge (₹50.00), FAC (₹0.00) and electricity duty (₹47.50) — that gives a gross bill of ₹997.50. With no subsidy in this state, ₹997.50 is your payable.
Here is the same 250 units across every DISCOM in Sikkim — useful when your board's name differs from the common one:
| DISCOM | Energy | Fixed | FAC | Duty | Subsidy | Total |
|---|---|---|---|---|---|---|
| Energy & Power Dept | ₹900.00 | ₹50.00 | ₹0.00 | ₹47.50 | — | ₹997.50 |
Does Sikkim offer a free-unit scheme?
Sikkim currently bills without a domestic free-unit subsidy, so the calculator's checkbox stays off and no green deduction line appears. That is tariff design, not an error — the energy charge is collected in full and the fixed charge, FAC and duty apply on top. If the state announces a scheme, we add it to the data and the toggle lights up automatically.

The table below is generated from the same data the calculator uses, so what you see here is exactly what is charged. Looking for the per-unit electricity price in The slab column IS your per-unit rate — each rate applies only to the units inside its own slab range.
| DISCOM | Slabs | Fixed charge | FAC |
|---|---|---|---|
| Energy & Power Dept | 1–50 @ ₹2.1, 51–100 @ ₹3.1, 101–200 @ ₹4.1, 201–400 @ ₹4.6, 401–above 401 @ ₹5.1 | ₹50/month | ₹0/unit |
Remember: in telescopic billing each slab rate applies only to the units inside its range. Many websites multiply one rate by total units — that is wrong and overstates bills. This calculator, like your DISCOM, adds slab by slab.
4 practical ways to lower your Sikkim bill
- The ₹2.10 opening slab is among India's cheapest — the first 50 units cost almost nothing.
- Electric heating in winter is the main driver; room-wise heaters and warm clothing first.
- Sikkim's five-slab ladder rewards staying under 100 units — the rate doubles beyond it.
- A solar water heater suits the cold-morning pattern and trims the geyser line.
