How Assam per-unit rates are set

The Assam State Electricity Regulatory Commission publishes an annual tariff order specifying slab rates, fixed charges, fuel adjustment formulas, and electricity duty for each DISCOM. For domestic consumers in Assam, APDCL uses a telescopic billing structure — meaning each slab applies only to the units within that slab range.

The headline per-unit rate is only the energy charge. Your full bill also includes a fixed charge (typically ₹50/kW/month), Fuel & Power Purchase Cost Adjustment (FAC / FPPCA, set monthly) and an electricity duty of 6%. Together these can add 15–30% to the effective per-unit cost.

Tariffs are typically revised once a year, with mid-year FAC pass-through revisions for fuel cost volatility. We verify Assam rates against the official tariff order every quarter. Last verified: 2026-04-22.

Assam electricity rate — FAQs

Answers to the most common electricity bill questions in India.

What is the electricity unit rate in Assam in 2026?
As per the latest SERC tariff order, domestic electricity rates in Assam range from ₹5.99/unit (entry slab) to ₹7.94/unit (highest slab). Exact slab rates differ between DISCOMs — see the table on this page for APDCL.
How much does 1 unit (1 kWh) of electricity cost in Assam?
1 unit = 1 kWh in every Indian state including Assam. The cost of 1 unit at APDCL starts at ₹5.99 for the first slab and rises with consumption. Add fixed charges, FAC and electricity duty to get the effective per-unit cost. See the 1-unit kWh calculator for a full breakdown.
Why does the per-unit rate change as I use more electricity?
Assam uses a telescopic slab structure for domestic consumers. Only the units that fall within each slab are charged at that slab's rate, so cheaper units stay cheap even as you climb slabs.
What is the commercial electricity rate in Assam?
Commercial (LT) rates in Assam typically start at ₹7.75/unit and go up to ₹9.75/unit, plus a higher fixed charge per kW than domestic. Industrial tariffs are usually flat-rate.
Do these unit rates include fixed charges and FAC?
No — the per-unit rates shown are the energy charge only. Your actual bill also includes a fixed charge (₹/kW of sanctioned load), Fuel Adjustment Charge (FAC, varies monthly), electricity duty (a percentage of energy charges), and sometimes meter rent. The effective per-unit rate is typically 15–30% higher. Use the bill calculator for the all-in figure.
