Why Your Industrial Electricity Bill in India Keeps Rising

At some point in the last few years, your electricity bill stopped looking like a utility invoice and started looking like a tax return. Multiple line items. Charges with names that sound interchangeable. A total that is reliably, inexplicably higher than the number you calculated by multiplying your units consumed by your “per unit rate.”

You are not miscalculating. The bill is genuinely that complicated — by design, as it happens — and most of what makes it complicated is working against you.

India’s industrial and commercial consumers pay some of the highest effective electricity tariffs in Asia. Not because energy is expensive to generate here — in fact, with solar and wind now among the cheapest generation sources in the world, the raw cost of producing electricity in India has never been lower. The gap between what it costs to produce a unit of electricity and what your business pays for it is filled by a system of charges, cross-subsidies, and regulatory levies that most business owners have never had anyone properly explain to them.

This article does exactly that. A complete breakdown of what is actually on your industrial electricity bill, why every charge exists, which ones are discretionary (or avoidable), and what the businesses who are paying significantly less than you are doing differently.

The Number You Think You Pay Is Not the Number You Actually Pay

Here is the single most important thing to understand before anything else: the “per unit rate” printed in your state’s tariff schedule is not your real cost of electricity.

A Karnataka HT industrial consumer might see a base energy charge of ₹6.75 per unit. A textile manufacturer in Tamil Nadu might note a commercial rate of ₹7.50. A factory in Assam is paying ₹9.29. These are the numbers business owners quote when asked what they pay for power.

The actual landed cost — once every surcharge, levy, and fixed charge is divided across total units consumed — is typically 30 to 50 percent higher.

That gap is not a billing error. It is the accumulated weight of a series of charges that each have their own justification, their own regulatory history, and their own trajectory of growth. Understanding them individually is the only way to understand your total bill — and the only way to identify which parts of it are reducible.

What Is Actually on Your Industrial Electricity Bill

1. Energy Charges

This is the base per-unit rate — the number most business owners focus on, and in isolation, the least complete picture of what electricity actually costs. Energy charges are set by your State Electricity Regulatory Commission (SERC) and revised periodically, typically once a year. In practice, they move in one direction.

2. Fixed Charges / Demand Charges

This is the charge that confuses most business owners because it has nothing to do with how much electricity you actually consumed. Demand charges are levied based on your contracted maximum demand — the peak load your facility is authorised to draw from the grid in any given 15-minute interval, measured in kilowatts or kilovolt-amperes.

You pay this charge every month whether your machines run at full capacity or sit idle. It is the DISCOM’s way of recovering the cost of the infrastructure it had to build and maintain to serve your peak demand — substations, transformers, transmission lines — regardless of whether you use it. For a manufacturing business with seasonal production cycles or variable shifts, demand charges can represent a significant percentage of the total bill.

3. Fuel Adjustment Charge (FAC / PPAC)

The name gives away the logic. Power distribution companies in India source most of their electricity from coal-based thermal plants, and coal prices move with global commodity markets. When coal prices rise, DISCOMs pass that increase directly to consumers through a variable monthly adjustment called the Fuel Adjustment Charge (FAC) or Power Purchase Adjustment Cost (PPAC), depending on your state.

This charge is not fixed, not predictable, and not within your control. It appears on your bill as a number that changes every month based on your DISCOM’s fuel procurement costs in the previous period. In states with high dependence on imported coal, this component has been a significant driver of bill increases over the past three years as global coal prices spiked and remained elevated.

4. Cross Subsidy Surcharge (CSS)

This is the charge that most directly explains why industrial and commercial consumers pay so much more than domestic ones — and it is worth understanding properly because it is one of the most structurally significant items on your bill.

India’s electricity pricing system is built on a cross-subsidy model. Domestic consumers, farmers, and small establishments are charged below the actual cost of supplying them electricity — sometimes significantly below. Someone has to cover the shortfall. That someone is you.

The cross subsidy surcharge is a direct levy on HT industrial and large commercial consumers, designed to compensate DISCOMs for the subsidy they extend to lower-tariff categories. In many states, it represents ₹1.00 to ₹2.50 per unit on top of the base energy charge. It is, in plain terms, a transfer of cost from residential consumers to businesses — one that grows as the gap between subsidised and cost-reflective tariffs widens.

5. Renewable Energy Surcharge / Additional Surcharge

Here is the one that should make every industrial business owner stop and read carefully.

Buried in your electricity bill is a charge of approximately ₹0.50 to ₹0.80 per unit — in many bills labelled as a Renewable Purchase Obligation (RPO) surcharge or Renewable Energy Surcharge — that you are paying every month for renewable energy. Not for the renewable energy your facility uses. For the renewable energy transition India is funding at a national level, which your conventional grid supply is not part of.

Your factory runs on coal-based grid power. You pay a renewable energy surcharge on every unit of that coal-based power. You are subsidising a clean energy system that delivers nothing to your business while receiving nothing from it.

This is not an oversight in the system. It is a deliberate mechanism to fund India’s renewable build-out. But it is worth naming clearly: as an industrial consumer on conventional grid supply, you are paying for the renewable energy transition without receiving any of its benefits.

6. Electricity Duty / State Tax

A percentage-based levy imposed by state governments — typically between 5 and 20 percent of your base energy and demand charges, varying significantly by state and consumer category. In some states this goes directly to the state treasury; in others it funds specific infrastructure programmes. Either way, it adds materially to your total bill and compounds as the underlying charges rise.

7. Power Factor Charges / Reactive Power Penalties

If you run significant inductive loads — motors, compressors, HVAC systems, welding equipment — your facility draws reactive power from the grid in addition to the active power that does actual work. DISCOMs require industrial consumers to maintain a power factor above a minimum threshold (typically 0.85 or 0.90 lagging). If your power factor falls below this threshold, you pay a penalty on your bill. If it exceeds it, you receive a rebate.

Many manufacturing businesses haemorrhage money through power factor penalties without ever identifying it as a discrete problem. The solution — installing power factor correction capacitors — is typically cheap, straightforward, and pays for itself quickly. But because the charge appears as a line item most finance teams have not been trained to interrogate, it persists.

8. Time of Day (TOD) Charges

Most HT industrial consumers in India are on Time of Day metering, which means the per-unit energy charge varies by when electricity is consumed — higher during peak demand hours, lower during off-peak periods. If your production schedule is inflexible, TOD charges simply add to your cost. If you have some flexibility in when you run energy-intensive processes, TOD tariffs create a genuine opportunity to reduce your bill by shifting load into off-peak windows.

Why Industrial Consumers Are the System’s Preferred Target

Understanding why all of these charges fall disproportionately on industrial and commercial consumers requires understanding how India’s electricity system is structured and who it is designed to serve politically.

Domestic consumers vote. Agricultural consumers vote. Small establishments vote. Industrial consumers are a small percentage of the population and a large percentage of electricity revenue. The cross-subsidy model, in its current form, reflects this arithmetic directly: businesses bear an outsized share of the system’s costs because they are the least politically costly group to burden.

This is not a cynical observation — it is simply the structural reality that explains why industrial electricity tariffs in India have risen faster than inflation, faster than domestic tariffs, and faster than the cost of generation for the better part of two decades. Every state budgeting exercise involves decisions about how much subsidy to extend to favoured consumer categories. The bill for those decisions lands on your desk each month.

The trajectory will not reverse. The structural pressures driving it — rising agricultural subsidy obligations, ageing distribution infrastructure requiring capital expenditure, growing renewable purchase obligations — are all moving in one direction. The businesses that have found a way out of this dynamic are the ones that have stopped depending on the DISCOM for their power.

The Charges You Can Escape and the Ones You Cannot

Not every item on your electricity bill is equally unavoidable — and this is where the practical relevance of understanding your bill becomes clear.

Power factor penalties are entirely within your control. Correcting your facility’s power factor through capacitor banks is a straightforward, low-cost intervention that eliminates the penalty and often generates a rebate.

Demand charges can be partially managed through load scheduling and demand-side management — shifting the timing of large motors and compressors to flatten your peak demand profile. In practice, most businesses can reduce their maximum demand by 10 to 20 percent through operational changes alone.

TOD charges can be reduced through production scheduling, where the manufacturing process allows it.

But the Cross Subsidy Surcharge, the Renewable Energy Surcharge, the Fuel Adjustment Charge, the Electricity Duty, and the base energy charge itself — these are not reducible through operational efficiency. They are structural. They are set by regulators and state governments, and they will continue rising.

The only way to escape the structural charges is to change your relationship with the grid — specifically, to move from being a captive DISCOM consumer to an Open Access consumer who procures power directly from a renewable generator.

What Open Access Changes

Under an Open Access Power Purchase Agreement, an industrial or commercial business with a contracted demand of 100 kW or above purchases electricity directly from a solar or wind developer at a commercially negotiated rate.

The renewable energy surcharge disappears — because you are actually receiving renewable energy, not subsidising it from afar. The FAC disappears on those units — because your solar developer has no fuel cost to pass on. The base energy rate is typically 25 to 40 percent lower than your current DISCOM tariff, locked in for 15 to 25 years.

Wheeling charges, transmission charges, and a reduced cross-subsidy surcharge still apply to Open Access power — the grid infrastructure still needs to be maintained and paid for. But the total landed cost of Open Access renewable electricity, after accounting for every applicable charge, is consistently and significantly lower than staying on conventional grid supply.

The businesses making this switch are not doing so for ideological reasons. They are doing it because the financial case is clear, the process is manageable with the right advisor, and the alternative — absorbing compounding DISCOM tariff increases indefinitely — is one they have chosen to stop accepting.

Where to Start

Pick up your last three months of electricity bills. Add up every charge that appears on them — not just the energy charge, but every line item. Divide the total by the number of units consumed. That number is your real cost per unit of electricity.

Then compare it to what an Open Access solar agreement would cost in your state, at your consumption level, including all applicable charges.

That comparison, done honestly, is where most business owners encounter the clearest possible argument for making the switch.

At Open Access Exchange, we build that comparison for businesses across India — with precise, state-specific numbers — before asking for any commitment. If the case is there, you will see it. If it is not, we will tell you.
