Direct Answer: How Does Karnataka’s Gruha Jyothi Electricity Subsidy Work?

Karnataka’s Gruha Jyothi scheme waives 100% of electricity bills up to your entitlement (12-month average consumption + 10%, max 200 units), resulting in a ₹0 Zero Bill. If you consume over your entitlement but $\le 200$ units, you pay only for excess units. Consuming 201+ units triggers complete disqualification, requiring full bill payment!

KERC LT-2(a) Domestic Electricity Tariff Slabs (Official Rates)

The Karnataka Electricity Regulatory Commission (KERC) mandates unified residential tariffs across all DISCOMs in Karnataka. Domestic power bills consist of four statutory components:

1. Telescopic Energy Slabs
• First 100 Units (0 – 100 kWh): ₹4.75 per unit
• Above 100 Units (101+ kWh): ₹7.00 per unit

Telescopic billing means everyone pays ₹4.75 for their first 100 units. Only units in excess of 100 are charged at the higher ₹7.00 marginal slab rate.

2. Fixed Charges & Statutory Taxes
• Fixed Charge: ₹110 (1st kW) + ₹210/kW (additional load)
• Fuel Adjustment (FAC): ~₹0.24 per unit
• Karnataka Electricity Duty: 9.0% on (Energy + FAC)

Fixed charges are based on sanctioned connected load. A standard 2 kW apartment pays ₹320/month in fixed charges (₹110 + ₹210).

How Gruha Jyothi Entitlement is Calculated (The Official Math)

Many consumers assume Gruha Jyothi offers a flat 200 free units to every household. Under the Energy Department of Karnataka guidelines, your entitlement is personalized:

Monthly Entitled Units = Min(200, Round(Average Monthly Units of Preceding 12 Months × 1.10))
Rule A: 100% Zero Bill (₹0)

If current consumption is $\le$ Entitled Units and under 200 units, the state waives energy charges, fixed charges, FAC, and tax. You pay ₹0.00.

Rule B: Partial Bill (Excess Units)

If consumption is > Entitlement but $\le$ 200 units, you get subsidy for entitled units and only pay for the excess units at ₹7.00/unit + tax.

Rule C: 200-Unit Disqualification

If consumption is > 200 units (even 201 units!), you lose 100% of the subsidy and must pay the full commercial bill!

The 200-Unit Cliff Trap: The ₹1,650 Shock for 1 Extra Unit

Examine the staggering financial difference between consuming exactly 200 units versus 201 units in a standard 2 kW Bengaluru household:

Frequently Asked Questions (BESCOM & Gruha Jyothi)

Expert answers to KERC slabs, 12-month entitlement calculations, and billing cliff rules.

How does the Gruha Jyothi 200 units free electricity scheme work in Karnataka?▾
The Gruha Jyothi scheme provides free electricity to registered domestic households in Karnataka. Unlike Delhi’s flat 200-unit rule, each household in Karnataka receives a personalized monthly entitlement calculated as their Average Monthly Consumption over the preceding 12 months + a 10% bonus, capped at 200 units. If your monthly consumption is less than or equal to your entitlement (and under 200 units), you get a 100% Zero Bill (₹0).
What is the 200-unit cliff trap under the Gruha Jyothi scheme?▾
The 200-unit cliff trap is the strict ceiling rule of the Gruha Jyothi scheme: if your total consumption in any month exceeds 200 units (even by just 1 unit, e.g. 201 units), you are 100% disqualified from the scheme for that month! You receive zero government subsidy and must pay the full commercial domestic bill for the entire 201+ units, causing your bill to jump instantly from ₹0 to over ₹1,650.
What happens if my electricity consumption exceeds my 12-month entitlement but remains under 200 units?▾
If your consumption is above your personal entitlement but does not exceed 200 units, you receive a Partial Bill. The Government of Karnataka waives the charges for your entitled units, and you only pay for the excess units consumed beyond your entitlement at the applicable KERC marginal slab rate (₹7.00/unit), plus proportional fixed charges and 9% electricity tax.
What are the current KERC LT-2(a) domestic electricity tariff slabs in Karnataka for 2026?▾
Under the KERC unified LT-2(a) domestic tariff: Energy charges are telescopic: 0 to 100 units at ₹4.75 per unit, and above 100 units at ₹7.00 per unit. Fixed charges are ₹110 per month for the first 1 kW of sanctioned load, plus ₹210 per kW per month for each additional kW. Fuel Adjustment Charges (FAC) average ₹0.22 to ₹0.26 per unit, and Karnataka Electricity Duty is 9% on Energy Charges + FAC.
How is the entitlement calculated for new tenants or new houses without 12 months billing history?▾
For new domestic connections or newly moved tenants without 12 months of previous billing history under the same consumer account, the Government of Karnataka applies a default provisional entitlement of 53 to 60 units per month (based on state domestic averages) until a 12-month track record is established.
Which electricity distribution companies (DISCOMs) are covered by KERC tariff in Karnataka?▾
All 5 state DISCOMs operate under KERC regulations: (1) BESCOM (Bengaluru Urban, Rural, Tumakuru, Kolar, Davanagere, Chitradurga); (2) MESCOM (Mangaluru, Udupi, Shivamogga, Chikkamagaluru); (3) HESCOM (Hubballi-Dharwad, Belagavi, Haveri, Bagalkote); (4) GESCOM (Kalaburagi, Bidar, Raichur, Ballari); and (5) CESC (Mysuru, Mandya, Hassan, Kodagu).
