Maharashtra C&I tariffs are falling — what it means

July 2026 · 7 min read

The short version: electricity tariffs for commercial and industrial consumers in Maharashtra are on a downward path, not an upward one. If a solar company has told you otherwise, they are either working from an out-of-date script or an imported one.

This matters, because almost the entire solar industry sells on the same premise — that grid power gets more expensive every year, so you should lock in cheaper generation now. In many markets that premise is sound. In Maharashtra, right now, it isn't.

What the order actually says

The Maharashtra Electricity Regulatory Commission sets tariffs through a multi-year tariff process rather than year by year. The operative order directs a reduction of roughly 10% in FY2025-26, and a cumulative reduction of around 16% by FY2029-30, with a sharp cut to the cross-subsidy that commercial and industrial consumers have historically carried.

Read that last clause twice. C&I consumers in Maharashtra have long paid above the cost of supply in order to subsidise other categories. The direction of travel is to narrow that gap. If you run a factory in this state, you have been the one paying the premium — and the premium is being reduced.

We are deliberately not quoting a rupees-per-unit figure here. The schedule is category-specific and changes with each order, and a stale number is worse than none. Your own bill has the current one on it.

Why this breaks the standard pitch

The conventional solar argument runs: tariffs rise about 5% a year, so over 25 years you avoid an enormous and growing cost, and here is a payback figure built on that curve.

Remove the escalation assumption and that model changes shape considerably. A proposal whose returns depend on tariffs climbing every year is not a proposal about your roof. It is a bet on a regulatory forecast, presented as engineering.

We think that is the wrong thing to sell, quite apart from being the wrong thing to say in Maharashtra. It is also fragile: the moment the assumption is questioned, the whole case wobbles.

The argument that survives

Here is what does not depend on tariff direction.

A tariff is a policy variable. It is reset periodically by a regulator weighing subsidies, fuel costs, distribution losses and political pressure. It can go down, as it is doing now. It can go up later. What you cannot do is plan around it, because you do not control it and neither does your supplier.

A solar asset on your roof removes that variable for the portion of your load it serves. Once it is built and paid for, the cost of the units it generates is fixed for the life of the system — roughly 25 years — because the fuel is free and the only ongoing cost is maintenance. You are not betting that grid power gets more expensive. You are removing a line item from the list of things that can move against you.

That argument holds whether tariffs rise, fall, or stay flat. It is the reason we lead with price certainty rather than savings theatre, and it is why our homepage says tariffs rise and tariffs fall — a solar asset on your roof doesn't care.

How to read a proposal in this light

Three questions worth asking any vendor, including us:

• What tariff escalation rate does your model assume? If the answer is 4-5% a year in Maharashtra, ask them to justify it against the current order. If the answer is “none”, the model is more honest and the numbers will look less exciting.
• Which of my units does this actually displace? Solar generates in daylight. If your load is concentrated on a night shift, a large system will export or curtail rather than offset, and the economics differ completely. This is a question about your shift pattern, not your roof.
• What happens to the case if tariffs fall another 10%? A serious vendor will have thought about it. If the proposal only works in one direction, you have found out something useful.

The honest caveat

We are not going to pretend falling tariffs are good news for solar economics. They are not. Cheaper grid power narrows the gap that a rooftop system has to beat, and it means the case has to be made more carefully — from your consumption pattern, your tariff category and your roof, rather than from a spreadsheet with an optimistic curve in it.

What it does not do is remove the case. Generation on your own roof is still generation you are not buying, at a cost you control, for two and a half decades. It just means the number has to be real.

That is the whole reason we publish a claims file and refuse to print a figure we cannot substantiate. In a market where the standard pitch is factually wrong about the home state, being the vendor that tells you so is not a marketing angle. It is the minimum.
