APDCL Billing Structure: Slabs, Categories, and Subsidies
Assam’s residential billing is split into three distinct categories based on connected load and consumption limits. Understanding which category your home falls under is key to predicting your charges:
- Jeevan Dhara (LT-I): A highly subsidized flat-rate category designed for low-income households. It applies only to connections with a load up to 0.5 kW and a monthly consumption of 45 units or less.
- Domestic-A (LT-II): The standard residential connection for the vast majority of households in Assam, covering connected loads from 0.5 kW up to 5 kW. It uses a 5-tier telescopic slab system.
- Domestic-B (LT-III): For larger residential homes with a connected load between 5 kW and 30 kW. It features a 3-tier telescopic system with slightly higher base rates.
In addition to energy rates, APDCL charges a flat monthly fixed charge (ranging from ₹40 to ₹70 for domestic users) and a state Assam electricity duty 5% calculated on the total energy bill amount.
☀️ Solar ToD Rebate: A Unique Incentive in Assam
To encourage green energy adoption, APDCL offers a 20% rebate on energy charges for consumption during solar hours (9:00 AM to 5:00 PM) for consumers equipped with smart meters. This Solar ToD rebate Assam initiative makes running heavy appliances during midday highly economical, helping you lower your effective monthly tariff.

APDCL Domestic Tariff Slabs (FY 2026-27)
The table below lists the complete APDCL domestic tariff rate slabs for residential consumers under standard categories:
| Category | Monthly Consumption Slab | Rate / Unit (₹) | Fixed Charge (₹/month) | Key Features |
|---|---|---|---|---|
| LT-I Jeevan Dhara | Up to 45 Units Only | ₹ 3.35 | ₹ 40.00 | Highly subsidized; load limit 0.5 kW |
| LT-II Domestic-A (0.5 kW to 5 kW) |
0 – 120 Units | ₹ 4.25 | ₹ 70.00 | Standard residential; telescopic slabs; eligible for Solar ToD |
| 121 – 240 Units | ₹ 6.30 | |||
| 241 – 300 Units | ₹ 7.20 | |||
| 301 – 500 Units | ₹ 7.40 | |||
| Above 500 Units | ₹ 8.19 | |||
| LT-III Domestic-B (5 kW to 30 kW) |
0 – 300 Units | ₹ 6.75 | ₹ 70.00 | Medium-large homes; higher base rates; telescopic |

Real Worked Examples Using the APDCL Domestic Calculation Formula
Example 1: Monthly Usage 100 Units — LT-II Domestic-A
Since 100 units is within the first slab (0-120), the calculation is straightforward:
| Billing Component | Calculation Detail | Cost (₹) |
|---|---|---|
| Energy Charge | 100 units × ₹4.25 | ₹ 425.00 |
| Fixed Charge | Flat monthly charge | ₹ 70.00 |
| Electricity Duty (5%) | 5% of Energy Charge (₹425) | ₹ 21.25 |
| Total Monthly Bill | ≈ ₹ 516 | |
Example 2: Monthly Usage 200 Units — LT-II Domestic-A
Because 200 units crosses the 120-unit mark, APDCL’s telescopic system bills the first 120 units at the lower rate, and the remaining 80 units at the next slab rate:
| Slab | Units | Rate (₹) | Cost (₹) |
|---|---|---|---|
| 0 – 120 Units | 120 | ₹ 4.25 | ₹ 510.00 |
| 121 – 200 Units | 80 | ₹ 6.30 | ₹ 504.00 |
| Fixed Charge | — | — | ₹ 70.00 |
| Electricity Duty (5%) | — | 5% of ₹1,014 | ₹ 50.70 |
| Total Monthly Bill | ≈ ₹ 1,135 | ||
Jeevan Dhara Scheme: Subsidized Tariff for Low-Income Households
The **Jeevan Dhara scheme APDCL** program is a targeted social welfare subsidy aimed at economically weaker sections. To prevent misuse, APDCL has set strict criteria:
- Connected Load Limit: Your sanctioned load must not exceed 0.5 kW. If you add heavy appliances and APDCL audits your load to be higher, you will be shifted to standard Domestic-A.
- Consumption Cap: You must consume 45 units or less per month. If your usage goes to 46 units or more in any given billing cycle, you lose the Jeevan Dhara rate for that month, and your bill is calculated at the standard Domestic-A rates from unit 1.
- Eligibility Check: To confirm **APDCL Jeevan Dhara eligibility and benefits**, ensure your connection classification code in your electricity bill is marked under the LT-I Jeevan Dhara category.
APDCL Commercial & Industrial Tariff Summary
| Category | Base Rate / Unit (₹) | Fixed Charge (₹/kW/month) | Applicability |

5 Practical Ways to Save Electricity Bill in Assam
💡 Pro Tip: Eliminate Your Electricity Bills with Solar!
Instead of just reducing your appliance usage, installing a grid-connected rooftop solar system can completely wipe out your electricity bills. You can generate your own power and even sell the excess back to APDCL. Use our new Assam Solar Bill Calculator to instantly estimate your installation cost, government subsidies, and monthly savings in seconds.
With telescopic tariffs jumping from ₹4.25 to ₹6.30 (a 48% increase) after the first 120 units, keeping your monthly usage under key slab limits has immediate financial returns. Here are five practical methods on **how to save electricity bill in Assam**:
1. Stay Within the 120-Unit Boundary
For standard **LT-II Domestic-A connection Assam** accounts, the first 120 units are billed at a very low ₹4.25 per unit. The 121st unit jumps immediately to ₹6.30. By keeping a weekly eye on your digital meter and aiming for a monthly total of 120 units or less, you avoid entering the higher-cost slabs entirely, keeping your bill around ₹500 to ₹600.
2. Run Heavy Loads During Solar ToD Hours
If you have an APDCL smart meter installed, take advantage of the 20% solar rebate program. Plan your washing machine, water geyser, and ironing tasks between 9:00 AM and 5:00 PM. The 20% discount on these energy-heavy activities effectively lowers your per-unit cost during midday hours.
3. Switch to BEE 5-Star Ceiling Fans
Assam experiences warm and humid monsoons, requiring fans to run constantly for months. A traditional induction ceiling fan consumes 75 to 80 watts. Upgrading to a 5-star Brushless DC (BLDC) motor fan reduces consumption to just 28 to 35 watts. Running three BLDC fans instead of old induction models saves 35 to 40 units per month, which translates to a saving of ₹150 to ₹250 on your APDCL bill.
4. Clean Air Conditioner Filters Bi-Weekly
Dust and humidity in Assam’s air clog AC air filters quickly. When filters are dirty, the compressor has to work twice as hard to cool the room, drawing significantly more current. Washing your AC filters every two weeks ensures maximum airflow, allowing the compressor to cut off earlier and saving up to 10-15% of your AC’s monthly power draw.
5. Audit and Minimize Standby Power
Leaving televisions, gaming consoles, desktop computers, and setup boxes plugged in on standby mode draws constant phantom power. In a typical home, this adds about 5 to 10 units to your monthly bill. In Assam, where every unit counts toward crossing into higher telescopic slabs, switching off appliances from the main wall switch eliminates this unnecessary waste.
Frequently Asked Questions (FAQs)
What happens if my consumption exceeds 45 units on a Jeevan Dhara connection?
If you exceed 45 units in a month, your connection will lose the subsidized Jeevan Dhara flat rate (₹3.35/unit) for that billing cycle. Instead, the entire bill will be recalculated based on standard Domestic-A rates, starting at ₹4.25 for the first slab. To prevent this, monitor your meter weekly and keep your consumption under 45 units.
Does APDCL charge a fixed fee monthly for domestic connections?
Yes. APDCL charges a flat monthly fixed charge of ₹70 for standard Domestic-A (LT-II) and Domestic-B (LT-III) connections, and ₹40 for Jeevan Dhara (LT-I) connections. This fee is constant and does not depend on how many units you consume during the billing period.
How do I verify if my APDCL bill is correct?
Take your total units consumed, apply the telescopic slab rates (₹4.25 for the first 120 units, ₹6.30 for the next 120, etc.), add the ₹70 fixed charge, and calculate the 5% electricity duty. Our online calculator does this automatically. If the final amount differs significantly, verify if any past arrears, fuel adjustments, or meter rents were added to your official bill.
How can I pay my APDCL bill online?
You can pay online via the official APDCL portal (apdcl.org) or by using their official mobile app “myBijulee”. Alternatively, you can use UPI applications such as Google Pay, PhonePe, or Paytm by searching for APDCL as the utility provider and entering your 12-digit consumer number.
