EPD — The Energy & Power Department, Government of Sikkim
Unlike most Indian states, Sikkim's electricity is not distributed by a corporatized DISCOM. The Energy & Power Department, Government of Sikkim (EPD) is itself the sole power distributor — a government department acting as a deemed licensee under the Electricity Act, 2003, directly responsible for generation, transmission and distribution across the entire state.
EPD — Government Department, Not a DISCOM
EPD operates across roughly 7,096 sq km and serves a population of around 6.08 lakh — making Sikkim one of the smallest and least populous states served by a single utility.
SSERC — Sikkim State Electricity Regulatory Commission
Headquartered in Deorali near Gangtok, SSERC approves all tariff orders, renewable energy regulations, and net metering policy for the state.
Teesta & Rangit Hydro Projects
Large hydroelectric projects like Teesta Stage V and the Rangit HEP generate far more power than Sikkim consumes, with surplus sold to the national grid — helping keep domestic tariffs low.

📋 Additional Charges (Domestic)
| Charge | Rate | Notes |
|---|---|---|
| Fixed Charge — Single-Phase | ₹50/month (flat) | Typical for small households — not based on sanctioned load in kW |
| Fixed Charge — Three-Phase | ₹200/month (flat) | 4x the single-phase charge — typical for larger homes/heavier appliance loads |
| Fuel Adjustment Charge (indicative) | ≈ ₹0.10/unit | Variable surcharge component seen on many Indian tariffs; not separately itemised in all public Sikkim sources |
| Electricity Duty | 5% of (Energy + Fixed Charges) | Applied to the combined total, not energy alone |
🏢 Commercial Rates — 2026 (Indicative)
| Units / Month | Rate (₹/unit) |
|---|---|
| 1 – 100 units | ≈ ₹3.50/unit |
| 101 – 300 units | ≈ ₹5.00/unit |
| Above 300 units | ≈ ₹6.50/unit |
Commercial rates carry "significantly higher base rates and steeper phase-based capacity charges" per EPD notices, but exact published slab breakpoints were not accessible for this page — figures above are indicative. Commercial fixed charge is approximately ₹150/month single-phase or ₹400/month three-phase.
How to Calculate Your Sikkim Electricity Bill
The exact method EPD uses to compute your monthly bijli bill, explained with each charge component.
Read Your Meter
Note total units (kWh) consumed for the month. Sikkim domestic and commercial bills are billed monthly.
Apply Telescopic Slabs
1-50 units at ₹1.10, 51-100 at ₹2.10, 101-200 at ₹3.10, above 200 at ₹4.10 — each band charged at its own rate.
Add the Phase-Based Fixed Charge
₹50/month flat for single-phase, or ₹200/month flat for three-phase — regardless of actual units consumed.
Add Fuel Adjustment
An indicative ≈₹0.10/unit surcharge, similar to fuel/power-purchase adjustments used across most Indian tariffs.
Apply the 5% Duty — On the TOTAL
Add energy charges + fixed charge together, then apply 5% duty to that combined figure — not to energy alone.
Total Bill
Total = Energy + Fixed + Fuel Adjustment + Duty. Compare with your EPD bill to verify accuracy.

Three-Phase
Advantages & Disadvantages of Sikkim's Electricity Tariff System
✅ Advantages
- ₹1.10/unit for the first 50 units is genuinely among the cheapest domestic rates anywhere in India.
- Even the top slab (₹4.10/unit above 200 units) is lower than the starting slab in many other states.
- Flat phase-based fixed charge (₹50 or ₹200) is simple to understand — no per-kW math required.
- A single government department (EPD) manages the entire state, avoiding multi-DISCOM confusion.
- Abundant hydro surplus, sold to the national grid, provides long-term price stability.
- Monthly billing keeps individual payments smaller and more predictable than bi-monthly cycles.
⚠ Disadvantages
- The 5% Electricity Duty is calculated on energy + fixed charges combined, not energy alone — a subtle but real extra cost.
- Three-phase connections pay a flat ₹200/month fixed charge — 4x the single-phase rate — regardless of actual usage.
- Commercial tariff breakpoints are not as clearly published as domestic rates.
- Remote high-altitude areas (Lachen, Lachung, Dzongu) can face meter-reading and supply disruptions from landslides and heavy snow.
- No widely publicised bulk free-unit subsidy scheme, unlike some neighbouring states.
- Being a small state, there's limited competitive pressure or alternative service options if disputes arise.
12 Proven Ways to Reduce Your Sikkim Electricity Bill
Stay Under 50 or 100 Units If Possible
Small households can often stay within the ₹1.10 or ₹2.10 slabs entirely, keeping the energy portion of the bill minimal.
Think Twice Before Upgrading to Three-Phase
A three-phase connection quadruples your fixed charge (₹200 vs ₹50/month) — only upgrade if you genuinely need the higher capacity for heavy appliances.
Consider an Induction Cooktop
Given Sikkim's cheap hydro-powered electricity, induction cooking can be a cost-effective alternative to LPG for many households.
Use Efficient Room Heaters in Winter
Higher-elevation areas like Lachen and Lachung need more winter heating — oil-filled or ceramic heaters use less power than old-style bar heaters for the same warmth.
Switch All Bulbs to LED
LEDs use 8-10W vs 40-60W incandescent — valuable during Sikkim's long monsoon and misty evenings when lighting runs for hours.
5-Star Inverter Appliances
5-star refrigerators and heaters use 25-30% less power, helping you stay in the cheaper slabs longer each month.
Solar for Remote Areas
For households in remote villages with less reliable grid access, small solar or micro-hydel systems can supplement EPD supply.
Eliminate Phantom Loads
TVs, set-top boxes and chargers left plugged in waste power year-round — use switchable power strips.
Air-Dry Laundry When Possible
Skipping the electric dryer during Sikkim's drier months (autumn, spring) saves meaningful power versus daily dryer use.
Leverage Natural Ventilation
Sikkim's cool mountain climate rarely needs air conditioning — natural ventilation and shade can handle most cooling needs.
Maintain Refrigerator Seals
Check door seals and avoid overloading — a well-maintained fridge in a cool climate uses noticeably less power.
Track Usage Monthly
Since the tariff jumps at 50, 100 and 200 units, a quick mid-month meter check helps you project and adjust before the bill arrives.

Sikkim Electricity Bill — Answered in Seconds
| Consumption | Rate |
|---|---|
| 1–50 units | ₹1.10 |
| 51–100 units | ₹2.10 |
| 101–200 units | ₹3.10 |
| Above 200 units | ₹4.10 |
30u × ₹2.10 = ₹63
Energy = ₹118 | Fixed = ₹50
Duty base = ₹168 → Duty (5%) = ₹8.40
Total = ₹176.40 / month
SSERC's 5% Electricity Duty is applied to energy charges + fixed charge combined. On a ₹168 base (₹118 energy + ₹50 fixed), that's ₹8.40 duty. If the duty applied to energy alone, it would only be ₹5.90 — a small but real difference.
Unlike states that charge fixed fees per kilowatt of sanctioned load, Sikkim charges a flat ₹50/month for single-phase or ₹200/month for three-phase connections — the same regardless of your exact load or usage.
Sikkim Electricity Consumer Rights & Complaint Process
Step 1: Contact EPD
Reach your local EPD sub-division office for billing errors, outages, or reconnection issues.
Step 2: CGRF
File with the Consumer Grievance Redressal Forum (CGRF), mandated under the Electricity Act 2003, if the local office doesn't resolve your issue.
Step 3: SSERC Ombudsman
Escalate unresolved cases to the Electricity Ombudsman appointed by SSERC, which can order bill corrections, refunds and penalties.
Solar Rooftop & Net Metering in Sikkim 2026
Sikkim already runs largely on clean hydro power, so solar isn't essential the way it is in coal-heavy states — but net metering is available and especially useful for remote areas with less reliable grid access.
How Net Metering Works
Sikkim's Grid Connected Rooftop Solar Photovoltaic System Policy (notified by EPD and regulated by SSERC) allows surplus rooftop generation to be credited against your bill under net or gross metering arrangements. The Sikkim Renewable Energy Development Agency (SREDA), an autonomous body under EPD, promotes renewable energy uptake statewide, including a past target of 50 MW of grid-connected rooftop solar. The PM Surya Ghar scheme offers a subsidy of up to ₹78,000 for systems up to 3 kW. Given Sikkim's already-low ₹1.10-₹4.10/unit domestic rates, payback periods run longer than in high-tariff states — solar makes the most sense for remote villages with unreliable grid supply or for larger commercial/institutional loads.

Smart Meters in Sikkim 2026
Why Smart Meters Matter Here
Beyond removing manual meter-reading visits — which can be genuinely difficult in remote, high-altitude, landslide-prone areas of North Sikkim — smart meters give EPD accurate, real-time consumption data instead of estimated billing.
📍 Sikkim Smart Meter Rollout
EPD is deploying smart meters under the central Revamped Distribution Sector Scheme (RDSS), with Gangtok prioritised. Check with your local sub-division office for your area's status.
Benefits for Consumers
- No estimated billing during monsoon/landslide-disrupted reading periods
- Instant consumption data via app
- Easier to track approaching the 50, 100 and 200-unit slab thresholds
- Reduces disputes over usage in remote areas
