Assam Official Tariff: Active for 2026 (Valid till 2027) Billing Cycle: Monthly (30 Days)

APDCL Electricity Bill Calculator 2026 – Assam Power Tariff & Solar ToD

Electricity distribution across Assam is managed by APDCL under retail tariff schedules approved by the Assam Electricity Regulatory Commission (AERC). Assam employs a load-split billing system where connected capacity determines your domestic tariff classification. Households with sanctioned loads under 5 kW fall under Domestic-A, featuring progressive telescopic energy slabs (0-120, 121-240, and 240+ units) and fixed charges of ₹75 per kilowatt. Residences with loads from 5 kW to 30 kW shift to Domestic-B, which carries higher energy rates and fixed charges of ₹120 per kilowatt. Furthermore, APDCL leads the country in smart meter innovation by offering a 20% Solar Time-of-Day (ToD) tariff discount for daytime electricity consumed between 9:00 AM and 5:00 PM. This calculator applies official AERC tariff schedules to compute exact monthly bills for both standard and smart prepaid connections.

How APDCL Electricity Bills Are Calculated in Assam (FY 2026-27)

Assam follows a load-split billing system governed by the Assam Electricity Regulatory Commission (AERC Tariff Order for FY 2026-27, Order dated 06 March 2026, Petition No. 20 of 2025). The commission maintained zero tariff hike, and the Government of Assam continued its targeted tariff subsidies for the 2026-27 fiscal year. In Assam, your sanctioned connected load decides your domestic tariff category: households with connected load below 5 kW are billed under Domestic-A, while homes with 5 kW to 30 kW are billed under Domestic-B.

LT-II: Domestic-A Load < 5 kW

For standard residential households with sanctioned load from 0.5 kW up to 4.99 kW. Uses 5 progressive slabs starting at ₹4.25/unit. Fixed demand charge is ₹70.00/kW/month.

Starting Energy Rate: ₹4.25 / u

LT-III: Domestic-B Load 5 to 30 kW

For larger homes, villas, and multiple air conditioner connections with sanctioned load between 5 kW and 30 kW. Starts directly at ₹6.75/unit for 0–300 units with ₹70.00/kW/month fixed charges.

Starting Energy Rate: ₹6.75 / u

LT-I: Jeevan Dhara ≤ 0.5 kW & ≤ 45u

Lifeline tariff for low-income families with sanctioned load ≤ 0.5 kW consuming up to 45 units/month. Flat rate of ₹3.35/unit and flat ₹40.00/month connection fee. Crossing 45 units shifts billing to Domestic-A.

Flat Energy Rate: ₹3.35 / u

LT-IV: Commercial 0.5 to 30 kW

For retail shops, private offices, hotels, restaurants, and non-residential establishments. Uniform flat energy charge of ₹8.94/unit across all consumption, plus ₹150.00/kW/month demand charges.

Flat Energy Rate: ₹8.94 / u

Taxes, Duties & Smart Meter Discounts in Assam

1. Assam Electricity Duty (5.00%) Under the Assam Electricity Duty Act, a state tax of 5.00% is charged on total energy charges across all LT categories. It is computed as: Electricity Duty = Energy Charges × 5%.

2. 20% Solar Time-of-Day (ToD) Rebate Consumers equipped with smart prepaid or postpaid meters receive an official 20% rebate on energy charges for consumption during daytime solar hours (9:00 AM to 5:00 PM). This rebate directly lowers your bill.

AERC FY 2026-27 Validated

⚡ Notice the AERC Connected Load Split in Action (Test 1 vs Test 2): A family using 150 units with a 2 kW load pays ₹873.95 under Domestic-A. If that same family had a sanctioned load of 5 kW, their bill rises to ₹1,413.13 under Domestic-B. Because 5 kW shifts your starting energy slab from ₹4.25 to ₹6.75/unit from unit 1, keeping your sanctioned load below 5 kW saves significant money each month.

💡 Practical Ways to Reduce Your APDCL Power Bill

1. Keep Connected Load Under 5 kW: The moment your connected load reaches 5 kW, APDCL classifies you under Domestic-B. Your base energy rate jumps from ₹4.25 to ₹6.75 per unit right from unit 1. If your sanctioned load is 5 kW but your peak requirement is less, submit a load reduction request on the APDCL myBijli portal or at your local sub-division office.

2. Run Power Appliances Between 9 AM and 5 PM: If you have an APDCL smart prepaid meter, take advantage of the 20% Solar Time-of-Day discount. Running water pumps, washing machines, iron boxes, and geysers during daytime hours directly cuts energy charges.

3. Keep an Eye on the 45-Unit Lifeline Limit: Jeevan Dhara consumers pay ₹3.35 per unit and ₹40 flat connection fee. If your monthly usage exceeds 45 units, the entire bill moves to Domestic-A rates, increasing your slab charges and demand fees.

4. Install Rooftop Solar Under PM Surya Ghar: In Assam, grid-connected rooftop solar offsets daytime usage and exports surplus power back to APDCL, helping bring monthly electricity bills down to near zero.

Frequently Asked Questions about APDCL Bill

Under AERC tariff schedules, residential categorization depends strictly on contracted capacity. Domestic-A applies to residential households with connected loads below 5 kW, using three progressive telescopic slabs (0 to 120, 121 to 240, and above 240 units) with fixed charges of ₹75 per kW per month. Domestic-B applies to larger residences with sanctioned loads from 5 kW to 30 kW, which are billed at higher base energy rates alongside fixed charges of ₹120 per kW per month.

Under landmark regulations issued by the Assam Electricity Regulatory Commission, domestic consumers equipped with smart electronic meters receive a 20% rebate on active energy charges for electricity consumed during designated solar hours (9:00 AM to 5:00 PM). This incentive encourages households to operate energy-intensive equipment like washing machines, water pumps, and air conditioners during peak solar generation hours when cheap green power fills the grid.

Jeevan Dhara is an exclusive lifeline tariff designed for economically vulnerable and BPL households across rural and urban Assam. To qualify, the connected load must not exceed 1.0 kW and monthly consumption must remain under 30 units. Power is provided at a subsidized rate of ₹4.35 per unit with a minimal fixed charge of ₹40 per month. If consumption exceeds 30 units in any month, the consumer is billed under regular Domestic-A rates.

FPPPA stands for Fuel and Power Purchase Price Adjustment. It accounts for fluctuations in the cost of natural gas from state fields, hydro power purchase rates, and interstate transmission charges incurred by APDCL. AERC audits these variations quarterly and approves FPPPA surcharges (typically ranging from 25 paise to 60 paise per unit) that appear as an additional line item on monthly bills.

APDCL smart prepaid meters provide several direct benefits: they eliminate physical meter-reading errors and delayed bills, allow real-time daily consumption tracking on the APDCL myBijli mobile application, provide an upfront 2% digital recharge discount, and enable automatic eligibility for the 20% daytime Solar Time-of-Day power discount.

To protect consumers from unexpected blackouts, APDCL smart meters have a built-in emergency credit buffer and friendly non-disconnection hours. Meters do not disconnect power automatically between 6:00 PM and 10:00 AM on weekdays, or on Sundays and recognized state holidays, even if the balance falls into negative. The temporary negative balance is automatically recovered on the subsequent digital recharge.
