HESCOM Electricity Bill Calculator (Updated)

Calculating an electricity bill manually can become difficult when energy charges, connected-load charges, fuel surcharge, electricity duty, and government subsidy benefits are applied separately. The calculation can be even more confusing for consumers who need to determine whether they qualify for Karnataka’s Gruha Jyothi Scheme.

The HESCOM Electricity Bill Calculator is a smart online utility designed for electricity consumers served by Hubli Electricity Supply Company Limited. It helps domestic households, commercial establishments, industrial units, and public EV charging operators estimate their monthly electricity expenses before receiving the official bill.

Using the supplied Karnataka Electricity Regulatory Commission FY 2026-27 tariff structure, the calculator applies the Domestic LT-1 single-slab tariff, Gruha Jyothi subsidy rules, Commercial LT-3 charges, Industrial LT-5 rates, EV charging tariffs, FPPCA fuel surcharge, fixed demand charges, and 9% State Electricity Duty.

HESCOM supplies electricity across important parts of North-Western Karnataka, including Hubballi-Dharwad, Belagavi, Uttara Kannada, Karwar, Haveri, Gadag, Bagalkot, Vijayapura, and nearby urban and rural areas.

Electricity usage can vary considerably across these regions. A family in Hubballi-Dharwad may use electricity for household appliances, air conditioning, and water heating, while a commercial establishment in Belagavi, an industrial unit in Gadag, or an EV charging station in Vijayapura may have a significantly different consumption and sanctioned-load profile.

The HESCOM Electricity Bill Calculator simplifies the calculation by displaying energy charges, connected-load charges, Gruha Jyothi subsidy deduction, FPPCA fuel surcharge, electricity duty, and the estimated net payable amount in a transparent itemized format.

What Is the HESCOM Electricity Bill Calculator?

The HESCOM Electricity Bill Calculator is an online electricity bill estimation tool developed for consumers of Hubli Electricity Supply Company Limited. It calculates the expected monthly electricity bill using consumption units, selected connection category, sanctioned load, and subsidy eligibility.

Unlike calculators that only multiply total units by one electricity rate, this tool calculates the main billing components separately. It applies the correct tariff and fixed demand charge according to the selected consumer category.

Under the supplied tariff structure, Domestic LT-1 consumers are charged through a simplified single energy rate of ₹7.00 per unit. The applicable fixed demand charge is calculated using the sanctioned load entered by the consumer.

Eligible domestic consumers registered under the Karnataka Government’s Gruha Jyothi Scheme can also calculate the subsidy benefit available for monthly consumption within the specified limit.

For example, if a registered domestic consumer uses 180 units during one month, the calculator can process the estimate as follows:

• Calculate the gross value of 180 units at the Domestic LT-1 tariff.
• Calculate the fixed demand charge according to sanctioned load.
• Calculate the applicable FPPCA fuel surcharge.
• Calculate State Electricity Duty where applicable.
• Apply the eligible Gruha Jyothi subsidy benefit.
• Display the estimated net payable amount.

Under the supplied scheme logic, a registered domestic consumer using up to 200 units can receive the applicable Gruha Jyothi benefit. When monthly consumption exceeds 200 units, the calculator applies the standard domestic billing calculation according to the configured scheme rule.

The calculator supports the following HESCOM consumer categories:

• Domestic LT-1 with Gruha Jyothi option
• Commercial LT-3 Non-Domestic Power and Lighting
• Industrial LT-5 Motive Power
• LT-6(c) Public EV Charging Station

This makes the tool useful for homeowners, tenants, landlords, shop owners, offices, hotels, restaurants, educational institutions, workshops, factories, manufacturing units, and EV charging operators across North-Western Karnataka.

How to Use the HESCOM Electricity Bill Calculator?

Key Features of This HESCOM Electricity Bill Calculator

This calculator is designed around the supplied KERC FY 2026-27 tariff information and includes the main components required for estimating a HESCOM electricity bill.

Why Is Our HESCOM Electricity Bill Calculator Different From Other Tools?

Estimating a HESCOM electricity bill requires more than multiplying the total monthly electricity units by one common rate. The final amount may include energy charges, sanctioned-load-based fixed demand charges, FPPCA fuel surcharge, State Electricity Duty, and an eligible Gruha Jyothi subsidy benefit.

The calculation also changes according to the selected connection category. Domestic LT-1, Commercial LT-3, Industrial LT-5, and LT-6(c) EV Charging consumers have different energy rates, load units, and fixed demand charges.

The HESCOM Electricity Bill Calculator applies the selected category automatically. Domestic consumers can enable the Gruha Jyothi option, while the calculator hides the subsidy setting when a commercial, industrial, or EV charging category is selected.

For registered domestic consumers, the tool checks whether monthly electricity consumption is within the supplied 200-unit Gruha Jyothi limit. If consumption is within the eligible limit, the applicable subsidy benefit is displayed separately. If consumption exceeds 200 units, the calculator prepares the bill using the standard domestic tariff rules configured for the tool.

Whether you are estimating a household bill in Hubballi-Dharwad, a commercial bill in Belagavi, an industrial electricity expense in Gadag, or an EV charging bill in Vijayapura, the calculator uses category-specific rates instead of one general Karnataka electricity formula.

HESCOM North-Western Karnataka FY 2026-27 Tariff Rates and Categories

The electricity tariff applicable to a HESCOM consumer depends on the selected connection category, monthly electricity consumption, and sanctioned load. Domestic connections use the supplied single-slab energy rate, while commercial, industrial, and EV categories follow separate rates and fixed demand charges.

The following tariff information is based on the supplied KERC FY 2026-27 data used for this calculator.

Domestic LT-1 Single-Slab Electricity Tariff

Under the supplied tariff structure, Domestic LT-1 consumers are billed using a simplified single energy rate rather than multiple consumption slabs.

How the Domestic LT-1 Calculation Works

The domestic energy charge is calculated by multiplying the total monthly electricity consumption by ₹7.00 per unit.

The calculator then adds the fixed demand charge according to the sanctioned load entered by the consumer.

• Energy charge: Total monthly units × ₹7.00
• Fixed demand charge: Sanctioned load in kW × ₹115
• FPPCA fuel surcharge: Total monthly units × ₹0.92
• Electricity Duty: 9% according to the configured bill calculation
• Gruha Jyothi benefit: Applied separately for eligible registered domestic consumers

Example: Domestic Consumer Using 180 Units

Suppose a Domestic LT-1 consumer uses 180 units during one month and has a sanctioned load of 2 kW.

• Gross energy charge: 180 × ₹7.00
• Fixed demand charge: 2 × ₹115
• FPPCA surcharge: 180 × ₹0.92
• Electricity Duty: Calculated at the configured 9% rate

If the consumer is registered and eligible under the Gruha Jyothi Scheme, the calculator displays the subsidy deduction separately and shows the estimated net payable amount after applying the configured scheme benefit.

How the Gruha Jyothi Scheme Is Calculated

The Karnataka Government’s Gruha Jyothi Scheme provides an electricity subsidy benefit to eligible registered domestic consumers. Under the supplied calculator logic, the subsidy option is available only when Domestic LT-1 is selected.

The calculator follows these basic rules:

• Registered domestic consumer: The Gruha Jyothi option can be enabled.
• Monthly consumption up to 200 units: The configured subsidy benefit is applied.
• Monthly consumption above 200 units: The bill is calculated according to the standard Domestic LT-1 tariff rules supplied for the calculator.
• Commercial, industrial, and EV consumers: The Gruha Jyothi option is hidden because the scheme is intended for eligible domestic connections.

Example: Registered Consumer Using 195 Units

A registered domestic consumer using 195 units falls within the supplied 200-unit consumption limit.

The calculator first prepares a detailed gross bill by calculating the energy charge, fixed demand charge, FPPCA surcharge, and electricity duty. It then shows the eligible Gruha Jyothi subsidy as a separate deduction and displays the estimated net amount.

Example: Consumer Using 225 Units

When monthly consumption reaches 225 units, it exceeds the supplied 200-unit Gruha Jyothi limit.

Under the supplied calculator logic, the standard Domestic LT-1 energy charge is applied to the total monthly consumption. Fixed demand charges, FPPCA surcharge, and electricity duty are then added according to the configured tariff rules.

Why the Subsidy Status Must Be Selected Correctly

The Gruha Jyothi benefit should only be selected by a registered and eligible domestic consumer. Enabling the option without valid scheme eligibility may produce an estimated bill that does not match the official HESCOM bill.

Consumers should check their latest electricity bill, scheme registration status, and official eligibility details before relying on the subsidy estimate.

Commercial LT-3 Non-Domestic Tariff

The Commercial LT-3 category generally applies to shops, offices, hotels, restaurants, clinics, educational institutions, business premises, and other eligible non-domestic power and lighting connections.

The commercial bill calculation also includes the configured FPPCA fuel surcharge and State Electricity Duty.

Example: Commercial Connection With 3 kW Load

Suppose a Commercial LT-3 consumer uses 300 units with a sanctioned load of 3 kW.

• Energy charge: 300 × ₹7.50
• Fixed demand charge: 3 × ₹240
• FPPCA surcharge: 300 × ₹0.92
• Electricity Duty: Calculated at the configured 9% rate

The Gruha Jyothi subsidy is not applied because the connection is commercial.

Industrial LT-5 Motive Power Tariff

The Industrial LT-5 category is intended for eligible motive-power connections, workshops, factories, production units, manufacturing facilities, processing units, and other low-tension industrial consumers.

Industrial consumers should enter the connected load in HP because the supplied LT-5 fixed demand charge is based on horsepower rather than kW.

Example: Industrial Connection With 10 HP Load

Suppose an Industrial LT-5 consumer uses 800 units with a connected load of 10 HP.

• Energy charge: 800 × ₹5.40
• Fixed demand charge: 10 × ₹170
• FPPCA surcharge: 800 × ₹0.92
• Electricity Duty: Calculated at the configured 9% rate

LT-6(c) Public EV Charging Station Tariff

The LT-6(c) category applies to eligible public electric vehicle charging stations operating within the HESCOM service area.

The calculator also adds the configured FPPCA surcharge and electricity duty to prepare the estimated EV charging electricity bill.

FPPCA Fuel Surcharge Applied to HESCOM Bills

FPPCA is a fuel and power purchase cost adjustment applied according to electricity consumption. Under the supplied calculator data, the FPPCA surcharge is ₹0.92 per consumed unit.

The FPPCA amount is shown separately so consumers can distinguish the base energy charge from the additional fuel-related adjustment.

State Electricity Duty Applied to HESCOM Bills

The supplied calculator data includes State Electricity Duty at 9%. The calculator determines the duty using the taxable bill component configured in the calculation system and displays it separately in the detailed report.

Electricity Duty is different from the energy charge and FPPCA surcharge. It is added after calculating the applicable billing components for the selected consumer category.

The exact amount shown on an official bill may vary if the statutory duty base, exemptions, subsidy treatment, or regulatory instructions differ for a particular consumer account.

How the Estimated HESCOM Bill Is Calculated

The calculator prepares the monthly electricity bill estimate through the following process:

1. Select the applicable HESCOM consumer category.
2. Multiply monthly consumption by the relevant energy rate.
3. Calculate the fixed demand charge using the entered kW or HP load.
4. Calculate the FPPCA surcharge at ₹0.92 per consumed unit.
5. Calculate State Electricity Duty at the configured 9% rate.
6. Apply the Gruha Jyothi subsidy when Domestic LT-1 is selected and the consumer satisfies the supplied scheme conditions.
7. Display the gross bill, subsidy deduction, and estimated net payable amount separately.

The official HESCOM bill may include additional items such as previous arrears, delayed payment surcharge, meter adjustments, deposits, penalties, regulatory revisions, or account-specific charges.

Why Entering the Correct Connected Load Is Important

The connected or sanctioned load directly affects the fixed demand charge. Entering an incorrect load can create a significant difference between the calculator estimate and the official electricity bill.

• Domestic LT-1: ₹115 per kW/month
• Commercial LT-3: ₹240 per kW/month
• Industrial LT-5: ₹170 per HP/month
• EV Charging LT-6(c): ₹70 per kW/month

Consumers should enter the load printed on their latest HESCOM bill or electricity connection document instead of estimating it from the number of appliances or machines used at the premises.

Electricity-Saving Tips for HESCOM Consumers

• Track monthly electricity usage: Check meter readings regularly to identify sudden increases in consumption.
• Monitor the Gruha Jyothi limit: Eligible domestic consumers should track monthly units when usage approaches the supplied 200-unit limit.
• Use LED lighting: Replacing traditional bulbs with LED lights can reduce household and commercial energy consumption.
• Choose efficient cooling appliances: Energy-efficient fans, refrigerators, and air conditioners can lower monthly electricity usage.
• Switch off standby equipment: Chargers, televisions, computers, and other appliances may continue using electricity when left connected.
• Maintain water pumps: Properly serviced pumps can reduce electricity consumption in homes, farms, and commercial properties.
• Manage commercial operating hours: Shops, hotels, and offices should avoid running lighting and cooling equipment unnecessarily.
• Maintain industrial motors: Correctly sized and regularly serviced motors reduce energy losses and operating costs.
• Optimize EV charging schedules: Charging operators should monitor energy usage and equipment efficiency to control monthly expenses.
• Review connected load: Ensure the sanctioned load matches the actual requirement because fixed charges are calculated using kW or HP.
• Compare previous bills: Month-to-month comparison can help detect faulty appliances, leakage, or unusual consumption patterns.
