The Factory Owner's Guide to Paying Less for Electricity — Without Waiting for the DISCOM to Change

Every factory owner knows the feeling. The electricity bill arrives, and the number has gone up again. You do the calculation in your head — another revision, another squeeze on margin — and then you set it aside, because what is there to do? You need the power. The DISCOM is the only one supplying it. And tariffs go one direction.

It is one of those costs that Indian manufacturers have treated for years as simply a fact of operating a factory in India. Unlike raw material prices, which you can negotiate and shop around for. Unlike logistics, where route optimisation and carrier competition give you some leverage. Electricity from your state distribution company arrives at the price the regulator approves each year, and your choices are to pay it or stop running your machines.

What a growing number of factory owners across India have discovered over the last few years is that this is not entirely true. There is a legitimate, well-established legal framework that allows manufacturers to purchase electricity directly from renewable energy producers at rates they negotiate — not rates that are set for them. It is called Open Access, and for energy-intensive manufacturers who haven’t seriously explored it, the numbers involved make it one of the most important business conversations you can have in 2026.

What Open Access Is — and Who It’s Designed For

Open Access is not a workaround or a loophole. It is a right established by the Electricity Act of 2003 — a framework specifically designed to introduce competition into India’s power market by allowing large electricity consumers to purchase power from generators of their choice, transmitted through the existing national and state grid infrastructure.

Industries with a connected load of 1 MW or more are eligible to participate. This threshold covers a wide range of manufacturers — mid-sized textile mills, food processing units, pharmaceutical manufacturers, auto component factories, steel processors, and similar facilities where heavy machinery runs for extended hours and electricity forms a significant share of monthly operating expenses.

Under Open Access, your business signs a Power Purchase Agreement directly with a renewable energy generator — typically a solar power plant, a wind farm, or increasingly a hybrid of both. The electricity that generator produces is fed into the grid and delivered to your facility through the same connection and infrastructure you already use. Your DISCOM remains involved for the last-mile distribution and for certain statutory charges. But the primary commercial relationship for your electricity supply — the price, the duration, the terms — is now between you and a generator who is not operating under a tariff regime that has been moving upward every year for the past decade.

The Savings That Are Showing Up in Practice

The financial case for Open Access is not built on optimistic projections. It is built on what is actually happening in the factories that have made the switch.

In Karnataka, Gujarat, Tamil Nadu, Andhra Pradesh, and Maharashtra — the states where Open Access adoption among industrial consumers has been most active — manufacturers are consistently reporting reductions in their effective electricity cost of 25 to 40 percent compared to conventional DISCOM supply. This is the landed cost figure — calculated after accounting for all the additional charges that apply to Open Access consumers: wheeling charges for use of the transmission network, transmission fees, cross-subsidy surcharges, and any other applicable statutory levies in a given state.

For a factory spending ₹60 lakh per month on electricity at current DISCOM rates, a 30 percent reduction represents ₹18 lakh saved every month. Annually, that is ₹2.16 crore that remains in the business rather than leaving through the electricity account. On a 20-year Open Access agreement — the kind of long-term structure that most manufacturers choose — the cumulative saving is a number that reframes the entire financial history of the business.

Beyond the per-unit saving, there is the stability dimension that experienced Open Access users consistently identify as the feature they value most. Your Open Access tariff is fixed for the contract period. The tariff revision that arrives next April, and the one after that, applies to your competitors’ DISCOM bills — not to your agreement. The gap between your electricity cost and theirs widens with every revision cycle, and that widening gap shows up in margin, in pricing flexibility, and in capacity to invest.

The Sustainability Angle That Has Become a Commercial Reality

When manufacturers in India first started exploring Open Access three or four years ago, the sustainability credential — the ability to report genuine renewable energy usage — was a secondary consideration. The cost saving was the argument; the clean energy story was a bonus.

That balance has shifted. For manufacturers supplying to large domestic groups with published ESG commitments, to international buyers with supplier sustainability requirements, or to any company that has started receiving detailed environmental questionnaires from its customers or investors — verified renewable energy usage has moved from a differentiating feature to a qualification criterion.

Open Access renewable energy provides the documentation that these evaluations require. The megawatt-hours of solar or wind power your factory consumes through an Open Access agreement are trackable and reportable in a way that a renewable energy certificate or a carbon credit is not. For a manufacturer in Tamil Nadu supplying to a European retail brand, or a pharmaceutical company in Gujarat working with an international distributor, that documentation supports commercial relationships that are genuinely at risk without it.

The cost saving and the clean energy credential are, through Open Access, the same decision — not competing priorities requiring separate solutions.

What You Should Know Before Making the Decision

Honest advice on Open Access requires acknowledging the variables that make the outcome different for different businesses.

State regulations governing Open Access — the specific charges that apply, the approval processes required, and the regulatory clarity of the framework — vary meaningfully across India. Karnataka, Gujarat, Tamil Nadu, and Andhra Pradesh are among the states where the framework is most developed and the process most navigable. Other states are at earlier stages of regulatory maturity, which can affect both the timeline for getting an Open Access arrangement in place and the specific economics of the resulting agreement.

Load requirements and consumption patterns also affect how Open Access arrangements are structured. A factory with highly consistent, predictable consumption across all hours is a different Open Access case from one with significant variation across shifts, seasons, or production cycles. The structure of the power purchase agreement — the contracted capacity, the supply guarantees, and the scheduling arrangements — needs to be tailored to your actual operating profile to deliver the saving reliably in practice rather than just on paper.

Approval timelines vary by state and by the specific regulatory requirements that apply to your facility’s connection and capacity. Working with an advisor who understands the process in your specific geography is the difference between an Open Access transition that moves efficiently and one that stalls in regulatory paperwork.

None of these are reasons to avoid Open Access. They are reasons to approach it with good information and proper support — which is what the right advisory partner provides.

The Conversation That Costs Nothing but Could Change a Great Deal

The factory owners who have already made the switch to Open Access are not looking back. They are operating with electricity costs that their DISCOM-dependent competitors cannot match, accumulating a cost advantage that grows more pronounced with every tariff revision cycle, and building a renewable energy track record that is opening commercial doors that require it.

The ones considering the move — who have read enough, heard enough from peers, or done enough rough calculations to know that it probably makes sense for their business — are in the position of every business owner who has identified an opportunity and not yet moved on it. The opportunity is still there. But so is the cost of not having moved earlier.

At Open Access Energy, we start every client conversation with the same thing: your numbers. Your actual consumption data, your state’s specific charges, and the available renewable options in your geography. We build the landed cost calculation with you, show you what the saving genuinely looks like for your business, and handle everything from developer selection to regulatory approvals to ongoing energy management if you decide to move forward.

Reach out to Open Access Energy today. The bill arrives every month whether you act or not. The only question is what number is on it.
