APDCL — Assam's Power Distribution Utility
Like Tamil Nadu, Assam is served by a single state-wide utility — APDCL (Assam Power Distribution Company Limited) — rather than multiple DISCOMs. All tariffs are set by the AERC (Assam Electricity Regulatory Commission) and apply uniformly across the state; APDCL organises its operations into broad zonal circles for billing and fault response.
APDCL — Distribution
Bills, meters and consumer service across every district of Assam. The same AERC-approved tariff applies from Guwahati to Silchar.
Guwahati, Dibrugarh & Jorhat Zones
The Lower Assam zone (Guwahati/Kamrup) is the largest consumer base; Upper Assam covers the tea-growing belt around Dibrugarh, Jorhat and Tinsukia.
Nagaon, Tezpur & Silchar Zones
Central Assam serves Nagaon and Tezpur; the Barak Valley zone (Silchar, Karimganj, Hailakandi) is administered separately due to its geographic separation from the Brahmaputra valley.
Assam Electricity Tariff 2026 — APDCL Domestic & Commercial
Rates per the AERC Tariff Order effective 1 April 2025 (FY 2025-26 schedule, continuing into 2026 pending revision). Assam categorises domestic tariffs by connected load, not by a usage tier like some other states.
🏠 Domestic-A (LT-II) — Connected Load Below 5 kW
Covers the vast majority of households in Assam. Telescopic — each slab is charged only for units within that band.
| Units / Month (kWh) | Rate (₹/unit) |
|---|---|
| 1 – 120 units | ₹4.25/unit |
| 121 – 400 units | ₹6.30/unit |
| Above 400 units | ₹8.19/unit |
🏡 Domestic-B (LT-III) — Connected Load 5 to 30 kW
For larger homes with higher sanctioned load. Starts from a higher base rate than Domestic-A.
| Units / Month (kWh) | Rate (₹/unit) |
|---|---|
| 1 – 200 units | ₹6.75/unit |
| 201 – 500 units | ≈ ₹7.50/unit |
| Above 500 units | ≈ ₹8.50/unit |
The ₹6.75 base rate is officially confirmed; higher-tier breakpoints above are indicative — refer to your APDCL bill or the AERC tariff order for exact figures.

📋 Additional Charges (All Domestic Categories)
| Charge | Rate | Notes |
|---|---|---|
| Fixed Charge (Domestic) | ≈ ₹70/month | APDCL publishes a range of ₹40-₹70 depending on load; ₹70 is typical for Domestic-A |
| FPPPA (Fuel & Power Purchase Cost Adjustment) | ≈ ₹0.15/unit | Variable, revised periodically to pass through fuel/power-purchase costs |
| Electricity Duty | 5% of energy charges | Applies to domestic AND commercial — Assam does not exempt domestic bills |
| Solar Time-of-Day Rebate | 20% off energy (smart meters) | For consumption during solar hours, 9 AM–5 PM |
🏢 Commercial (LT-IV) Rates — 2026
| Units / Month | Rate (₹/unit) |
|---|---|
| All units (flat, no slabs) | ₹8.94/unit |
Commercial connections do not get telescopic slabs — every unit is billed at the same flat rate. Fixed charge is ₹150 per kW of sanctioned load per month (e.g. a 5 kW connection pays ₹750/month fixed), plus the standard 5% Electricity Duty.
How to Calculate Your Assam Electricity Bill
The exact method APDCL uses to compute your monthly bijli bill, explained with each charge component.
Read Your Meter
Note total units (kWh) consumed for the month. Assam domestic and commercial bills are both billed monthly.
Check Your Category
Domestic-A (under 5kW), Domestic-B (5-30kW), or Commercial (LT-IV) — your sanctioned load determines which ladder applies.
Apply Slab Rates (Telescopic)
For domestic, each unit range is charged at its own rate — 1-120u at ₹4.25, 121-400u at ₹6.30, above 400u at ₹8.19. Commercial is a flat ₹8.94/unit throughout.
Apply Solar ToD Rebate (Optional)
Smart meter users get ~20% off energy charges for solar-hour (9 AM-5 PM) consumption — a genuine, easy way to cut your bill.
Add FPPPA + Fixed Charge
FPPPA ≈ ₹0.15 × total units. Fixed Charge ≈ ₹70/month (domestic) or ₹150/kW (commercial), regardless of consumption.
Add 5% Duty & Total
Electricity Duty = 5% of energy charges, applied to both domestic and commercial. Total = Energy + FPPPA + Fixed + Duty − ToD rebate (if applicable).

Advantages & Disadvantages of Assam's Electricity Tariff System
✅ Advantages
- Domestic-A's first-slab rate of ₹4.25/unit for the first 120 units is genuinely affordable for small households.
- The 20% Solar Time-of-Day rebate is a real, usable way to cut bills by shifting heavy appliance use to daytime.
- Jeevan Dhara offers meaningful protection for the poorest households with very small connections.
- Load-based categories (rather than usage-tier switching) make your applicable ladder predictable month to month.
- Single state-wide utility (APDCL) means consistent billing rules and support across all districts.
- Monthly billing (not bi-monthly) means smaller, more manageable individual payments.
⚠ Disadvantages
- The 120-unit cliff causes a sharp ~48% jump in per-unit rate right after a fairly low threshold — easy to cross with one AC.
- Unlike many states, Assam charges the 5% Electricity Duty on domestic bills too — no exemption for households.
- Commercial connections pay a high flat ₹8.94/unit rate with zero free-unit cushion and a steep ₹150/kW fixed charge.
- Domestic-B's higher-tier breakpoints beyond the ₹6.75 base are not fully published in accessible form — check your bill for specifics.
- FPPPA surcharge changes can happen with limited public notice, causing unpredictable month-to-month variation.
- Frequent monsoon-related outages in parts of the state can complicate consistent meter readings.
12 Proven Ways to Reduce Your Assam Electricity Bill
Stay Under 120 Units If Possible
The single biggest lever for small households: keeping monthly usage at or below 120 units locks in the cheapest ₹4.25/unit rate for your entire bill.
Use the Solar ToD Rebate
If you have a smart meter, run washing machines, water pumps and ironing between 9 AM and 5 PM to capture the 20% rebate on those units.
Set AC at 24–26°C
Every 1°C higher saves ~6% power. Assam's humid climate makes 24-26°C with a fan feel comparable to much lower settings.
Use a Dehumidifier, Not Just AC
Assam's humidity increases AC load significantly. A dehumidifier uses far less power than running AC purely to reduce moisture.
Switch All Bulbs to LED
LEDs use 8-10W vs 40-60W incandescent — especially valuable during Assam's long monsoon evenings when lights run for hours.
5-Star Inverter Appliances
5-star ACs and refrigerators use 25-30% less power, meaningfully reducing how fast you cross the 120 and 400-unit thresholds.
Use Voltage Stabilisers
Frequent voltage drops in parts of Assam can make appliances draw more power to compensate — stabilisers and inverter fans help.
Clean AC & Fridge Filters Often
Dust and humidity clog filters faster in Assam's climate, forcing appliances to work harder and use more power.
Turn Off Mosquito Repellent Lamps Early
Many Assam households run electric mosquito lamps nightly — switching off a few hours earlier adds up over a month.
Eliminate Phantom Loads
TVs, set-top boxes and chargers left plugged in waste 50-100 units/year — use switchable power strips.
Track Usage Monthly
Since Domestic-A's rate jumps sharply after 120 and 400 units, a quick mid-month meter check helps you project and adjust.
Check Consumption via APDCL App
Use the APDCL portal or mobile app to monitor usage trends and catch unexpected spikes before the bill arrives.

Unlike some states, Assam applies a 5% Electricity Duty on domestic bills too — calculated on the energy charge amount. Commercial connections pay the same 5%.
Assam Electricity Consumer Rights & Complaint Process
Step 1: Contact APDCL
Reach your local APDCL sub-division office or the consumer care helpline 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: AERC Ombudsman
Escalate unresolved cases to the Electricity Ombudsman appointed by AERC, which can order bill corrections, refunds and penalties.
Solar Rooftop & the Solar Time-of-Day Rebate in Assam 2026
Assam offers two distinct ways to cut your bill with solar: installing your own rooftop panels, or simply timing your usage to capture APDCL's 20% Time-of-Day rebate on grid power.
How the Solar ToD Rebate Works
Consumers fitted with a smart meter receive a 20% rebate on energy charges for consumption recorded between 9 AM and 5 PM — the hours of peak solar generation. This rewards shifting heavy appliance use (washing machines, water pumps, ironing) into daytime, easing evening grid demand without needing your own solar panels. For those who do go solar, net metering is also available: surplus rooftop generation exported to the APDCL grid is credited against your bill, and the PM Surya Ghar scheme offers a subsidy of up to ₹78,000 for systems up to 3 kW.
Assam Electricity Tariff History
Note: figures for years before the 2025 order are approximate milestones based on publicly available AERC notifications; refer to apdcl.org for archived tariff orders with exact historical slab rates.
Smart Meters in Assam 2026
Why Smart Meters Matter in Assam
Beyond removing manual meter-reading visits, a smart meter is a prerequisite for the 20% Solar Time-of-Day rebate — without one, APDCL cannot verify which units you consumed during solar hours (9 AM-5 PM), so you can't claim the discount.
📍 Assam Smart Meter Rollout
APDCL is deploying smart meters under the central Revamped Distribution Sector Scheme (RDSS), with urban centres like Guwahati prioritised. Check the APDCL portal or contact your local sub-division office for your area's status.
Benefits for Consumers
- Unlocks the 20% Solar ToD rebate
- No estimated billing — only actual usage charged
- Instant consumption data via app
- Eliminates meter-reading visits, useful during monsoon access disruptions
